MP EG audio decoder 2 6 makes the solution The digital audio signal output from the multiplexer 24 is properly recorded in the dynamic random access memory DRAM 26a, and then the decoding process is performed on the audio signal compressed by the MP EG method. The decoded audio signal passes through the digital / Analog converter 30 converts to analog signals. The audio signal of the left channel is output through a buffer amplifier 3 1 L, and the audio signal of the right channel is output through a buffer amplifier 31R. There is an RF modulator 4 1 that converts the composite signal output by the NT SC encoder 27 and the audio signal output by the digital-to-analog converter 30 to a radio frequency (RF) signal and outputs it. Furthermore, when the RF is modulated When the device 41 is set to TV mode, the RF modulator will detect the RF signal output from an AV device such as a cable box in order to output it to a VCR or another AV device, and The detected RF signal is NT SC standard. In this embodiment, these video and audio signals are transmitted to a monitor 4 via an AV line 11. The central processing unit CP U 2 9 performs various processing tasks according to the program stored in the read-only memory R0M3 7. For example, the CPU 29 controls the tuner 21, the QPSK decoding circuit 22, and the size of the paper.

Furthermore, CPU 2 9 The control signal sending and receiving unit 2A controlling the AV device can output a preset control signal to other AV devices through the control line 12. Furthermore, CPu 29 also receives control signals from other AV devices The button switch (Fig. 3) of the control panel 40 can be used to directly input a predetermined command to the central processing unit (CPU) 2 9. Furthermore, when the remote control is used for 5 inches, the IR transmitting section 51 will transmit a Infrared signal, after receiving this infrared signal, the IR receiver 39 transmits this light reception result to the CPU 29. In short, by the remote controller 5, a preset command can be input to the CPU 29. In addition, In addition to the MP EG video data and audio data output by the front-end device 20 The demultiplexer 24 also has an EPG data, which is output and recorded in the EPG area 35A of the data buffer memory 35. The EPG information includes each broadcast from the time to the next 10 hours Channel program information (such as program channel, broadcast time, title, category, etc.). Because the EPG information system performs regular broadcasts, the EPG area 3 5A can always maintain the latest EPG data. Furthermore, the CPU has prepared a The sorting table of EPG data is stored in the EPG area 35 A, and the sorting table is recorded in the static random access memory 36, which will be described in detail below. The system has EEPROM 38 (electrically erasable and removable) Standard read-only memory) can properly store some data that can be saved after the power is turned off. For example, in 4 weeks, the history of the programs received by the tuner 21 is before the power is turned off. The channel number of the last channel to watch.

Description of invention (I9) BSS used by a high-output inquiry machine equipped with a satellite The bandwidth is from 12 ♦ 2GHz to 12.7GHz. In this case, one data package in multiple channels (up to 9) will be multiplexed and transmitted to a preset frequency assigned to each answering machine The signal, in other words, each answering machine will transmit multiple channels of signals, but only one type of carrier is used. In short, for example, when the number of answering machines is 2 3, at most 2 0 7 (= 9 X 2 3) channel data can be transmitted. In I RD 2, the front-end device 20 is used to receive and decode the channel carrier corresponding to a predetermined answering machine, so that the packaging data in up to 9 channels can be obtained. The demultiplexer 24 temporarily records each data package taken from the demodulation output in a data buffer memory 35, and then reads it out, counting the packaging of EPG data (guidance data, channel data and program data) In addition to the header, the data part will be recorded in the EPG area 3 5 A, the video data package will be provided to the M PEG video decoder 25 and decoded, and the audio data package will be provided to the MP EG audio decoder 2 6 Decoding "The detailed processing method of the encoder shown in Fig. 10 can be found in the article" Technology Supporting the US Information Highway "published on pages 180 to 189 of the aforementioned Nikkei e-magazine. In each answering machine, scheduling must be performed (scheduling), so that the transmission rate is consistent, for the carrier assigned to each answering machine, the transmission rate is 40 million bits per second. For example, for sports programs, there is a strong dynamic image, MP E G video data will occupy a lot of data packaging. In short, when there are many such programs, the number of programs that can be transferred with one answering machine is again applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) --------- ¢ 1 ------ 1T ----- C4 (Please read the note on the back _Issues before filling in this page) A7 B7 Printed by the Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economy V. Description of Invention (20) Will become rare. At the same time, for screens similar to news broadcast by broadcasters, MP E G video data can be transmitted with less data packaging because of less dynamic images. In short, if there are many such programs, the number of programs that can be transmitted by one answering machine will become very large. Figure 11 shows the internal use of dynamic random access memory 2 5 a. For example, the screen resolution of the monitor 4 is 7 2 Ο X 4 8 0 pixels, the luminance signal of each pixel is represented by 8 bits, and the color difference signal is 8 bits by 1 pixel to 2 It is expressed by the ratio of pixels, and the number of bits representing the entire pixel is 4147200 (720x48 Ox 1 · 5x8) bits. Assuming that a word contains 64 bits, the number of pixels corresponds to 6 4 8 0 0 words, if expressed in hexadecimal digits, it becomes 0 XFD 2 0 words.

Description of the invention 24) 1 · 5 hours' as shown in FIG. 19 mentioned below) from the channels of the preset screen area 2 5 〇 (for example 7 channels, as shown in FIG. 1 9 mentioned below) read EPG area 3 5A The program data in the program is written into the OSD area 2 5 aA in the DRAM 25 a as bit-mapped data. The above-mentioned preset screen area 25 50 is taken from all EPG tables 240. Afterwards, the 'MPEG video decoder 25 reads the bit map data stored in the OSD area 2 5 a A and outputs this data to the monitor 4. In this way, the overall EPG, such as the general guidelines (Figure 19), can be displayed on the monitor 4. When the 〇SD data of characters and the like are displayed, the character data stored in the e PG area 35 A will be compressed, The dictionary is used to perform the original processing. Finally, the read-only memory 3 7 will store the compressed code conversion font. The compressed code conversion font contains a spelling database and a dictionary. The system has a spelling database and 3 types of characters. Thesaurus. This system uses two bytes of data to represent one word (w〇rd) 〃, the first byte represents one of the three word lexicons, and is marked with 0 ’1 and 3. In addition to the two-byte data, there are preset words (words) arranged in the order of 0 to 2 5 5 together with the remaining one byte, and each word is represented by a number. When the encoder at the transmitting end transmits a predetermined word, it actually transmits two bytes of data. In the read-only memory 37, a conversion font will be prepared on the encoder side. The conversion font is used to retrieve the two-byte code and assign it to the original word. In addition, when the characters of non-prepared characters are sent out, one kind of spelling is taken out of the 2 5 6 kinds of spellings that have existed before, and they are combined and a text is issued.

The invention description (25) is sent out, and the spelling is represented by a byte code. A read-only memory 3 7 records a correspondence table (address conversion table) 'This table contains character code and font bit mapping data storage location, by looking up the conversion table, you can read the corresponding Predetermine the bit-mapped data of the character code and write it into the OSD area 2 5 a A. Of course, the read-only mnemonic 3 7 stores the bit-mapped data in the preset address. Furthermore, the read-only memory 3 7 stores logo data for display, and at the same time, the read-only memory 3 7 stores an address conversion table for calling out a logo identification code and the logo corresponding to this identification code Information (bit mapping information). After the logo identification code is clarified, by reading the logo data and writing this data into the SD area 2 5 a A, the logo of each playback station can be displayed on the monitor 4, and the above logo data is Stored in an address corresponding to the identification code. By the way, the sorting table stored in the static memory 36 is stored by the channel number. When this sorting table is used to retrieve a specific channel or program, or to replace the order by sorting, etc. The sorting table will be updated. However, as described below, the position information (indicators) of channel data and program data are stored in this sorting table. The indicators and channel data of the program data are combined into a "group". When the program data and channel data are When updating, the data will be changed in units of 'group ^. The flow chart in Figure 14 illustrates how to prepare a sorting table that will be written to static memory 36. For example, suppose EPG occupies 4 of 200 channels. · 5 hours, the minimum period of each program is set to 0 · 5 hours (30 seconds), so a maximum of 9 programs can be sent in a channel, the paper standard is applicable to the Chinese National Standard (CNS > A4 is now Grid (2 丨 0X297mm) (please read the notes on the back side • the matters needing attention before filling in this page) 1-----i II--, I " J 1— — I ^^ 1-I--1 ^ · ^ I ——- -28-A7 ____B7_____ V. Invention Ming (26), please read the back note first. The matters before you. Fill in the nest. This clothing% According to this, 200 channels can send up to 1800 (= 200x9) programs. Therefore, the processing shown in Figure 14 In the example, the number of groups in the sorting table will be set to 1 8 0 0. When step SP 1 starts to be executed, the variable N will be initialized to zero first, after that, the variable L will be initially reduced to 1, and the variable N represents a sorting table. Group number (address), for example, the group number can be set from 0 to 1799. Furthermore, the variable L represents the channel number, where any value will be set from 1 to 2 0 0 »Order ci Next, perform step SP2, where The address PCL (PC1 in this example) of the EPG area 35A is used as the channel data index of the address N (in this example, N = 〇) of the ranking table N in the static memory 36, and the above-mentioned EPG area 3 5 A corresponds to the channel number L (in this example, the channel number is 1), and finally, in this example, the address PC1 is set in the EPG area 35A of channel 1 as an index of the channel data of the address 〇 Printed by the Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, followed by step SP 3, in the channel number L In the channel information of *, the offset of the first program and the number of the program can be obtained, and the offset of the first program is used to retrieve the program LM in step SP 5. Then execute SP 4, and first perform the variable M to In the initialization of 1, the variable M represents the number of programs in the same channel, and its value is set to any value in the range of 1 to 9. Furthermore, step SP5 is executed to correspond to the program L- M (in this example, In the EPG area 3 5A of the program 1-1), an address will be taken as the program data index of a certain address N (in this example, N = 0) in the ranking table. Finally, in this example, the Chinese national standard (CNS) A4 specification (210X297 mm) is applied in the program 1 ~ i of the paper standard -29-A7 _____ _B7_ printed by the Central Consumers ’Bureau of the Ministry of Economic Affairs _____ _B7_ In the EPG area 3 5A of (27), there is an address PP1 — 1 that is set as the address. The index of the program information. Then execute step SP6, the system will determine whether the variable M is the number of programs or more. When the value of M is less than the number of programs in the same channel, step SP7 will be executed, and the variables N and M will increase by 1, so the N can be obtained = 1 and M = 2. Next, step SP8 is executed. In the EPG area 3 5 Α corresponding to the channel number L (channel number 1 in this example), there is an address PC 1 set as the address N (in this example) The channel information at address 1) refers to Sassafras. Then 'return to step SP5, and the subsequent processing is performed in the same manner. Through the repeated execution of steps SP 5 to SP 8, PC 1 is stored at addresses 0 to 7 in the sorting table as channel data indicators as shown in FIG. 15 and, corresponding to program 1 — From 1 to EPG area 3 to 5 of program 1-8, the addresses PP 1-1 to PP 1-8 are stored separately as the program data index of addresses 0 to 7 in the sorting table " When the above processing is finished After that, in step SP6, if it is determined that the variable M is equal to the number of programs, step SP9 will be executed. In this step, it will be determined whether the variable N is greater than 1 7 9 9 or the corresponding channel data has not left. When these conditions are not met, S Ρ 1 〇 will be executed, so that the variable N and the variable L will increase by 1, in this example, it will be set to N = 8 and L = 2. After that, step SP2 will be executed to repeatedly execute the same process. Finally, as shown in Fig. 15, PC 2 is written to address 8 in the sorting table to this paper standard.

Description of invention (32) 2 2 0, according to the selection button 1 3 1 upward (above the operator), downward (in front of the operator), right and left For the direction control, the cursor 2 1 2 moves up, down, left and right respectively. Here, if the key switch 1 3 1 is selected to be further manipulated, the cursor 2 1 2 moves to the program name display area The upper, lower, right and left ends of 2 2 0 will scroll the display content of the program name display area 2 2 0, for example, when the cursor 2 1 2 stays in the bottom row of the program name display area 2 2 0, and When the selection key switch 1 3 1 is operated downward, the display content of the program name display area 2 2 0 will scroll up one column. Since the cursor 212 stays in the lowest column, and the entire EPG table 240 specifies all the EPGs in FIG. 13, the cursor 212 will move down by one column. According to the upward, downward and rightward movements, the display content will be scrolled up in the same way until the drawing head of the E PG table 240. Furthermore, in addition to the up, down, left, and right movements, the selection key switch 1 3 1 can also be used for upper left, upper right, lower left, and lower right controls. Since the selection key switch has 8 directions of operation, the cursor 212 can also be moved in 8 directions. The selection key switcher 131 can perform a series of manipulations such as 8 directions to move the cursor 2 1 2, while the vertical direction control (selection manipulation) of the selection key switch 1 3 1 is used to determine the selection of the program. The moving cursor 2 1 2 only needs to be controlled by the thumb, without having to hold the remote controller 5 with the other hand, so that more convenient maneuverability can be obtained. Here, if a remote controller with a 4-way tour key and a selection button is used to achieve a similar cursor movement function, multiple moving paper standards will be implemented to use the Chinese National Standard Falcon (常 呢) 84 specifications ( 210 father, 297 mm) Lu Qi ------ 1T ------ ^ (please read the note on the back side * and then fill out this page) -35-Beigong Consumer Cooperation Co., Ltd., Central Bureau of Standards, Ministry of Economic Affairs Print A7 _ _B7 ____-_ 5. Description of the invention (33) until the program is selected. For example, as shown in 囵 20, in order to display the cursor in the 4th row and the leftmost column in the program name display area 22〇 (a rectangular area displaying the program name in the time period from 9:30 to 10:00 in TBS 233) 2 1 2 Move to the lowest row and the rightmost column (a rectangular area showing the program name in the time slot of 10: 30 to 11: 〇〇 in SCFI), press the down arrow key three times and the right cursor key After the second time, the selection button must be pressed, so a total of 6 buttons are required. In addition, the button pressed each time is different, so you should use the other hand to hold the remote control. In order to replace the aforementioned 4-direction cursor key, it is considered to propose an 8-direction cursor key, and in this case, it is necessary to occupy a larger area on the remote control surface, which will hinder the design of the remote controller. Furthermore, more buttons must be added, which inevitably affects the controllability of the buttons. In this embodiment, the selection button is used as a cursor button that can move the cursor 2 12 in 8 directions. When using the thumb to arbitrarily manipulate the selection button switch 1 3 1 in 8 directions, the selection button can be used to borrow The thumb presses the selection button switch 1 3 1 vertically to confirm the selection of the program. From this, it can be seen that a series of operations moved from the cursor 2 12 to the program selection can be operated without holding the remote controller with the other hand, that is, only the thumb is required at any time. In the above general guide screen, the name of EP (General Guide) can be displayed, the Chronicle of the station selected at that time, the content of the program, and the date at that time.

Invention Description (39) If there is an input action for further cursor movement, the processing action performed at that time will be suspended and immediately Start the process corresponding to the newly entered Sassafras move. In step s P 67, if it is determined that it is not necessary to display the pay-per-view program, then proceed to step SP 68 and notify the MP EG video decoder 2 5 Process blue package image output. Finally, during the execution of step SP 74, the overall guidance background image shown in FIG. 20 displays the program image specified by the cursor 2 1 2 and also outputs the audio signal accompanying the image. At the same time, if the cursor 2 1 2 specifies a pay-per-view program, and the registration is not required, the background image will be completely blue, and there will be no sound output. If the cursor specifies a pay-per-view program, the program will not be received under certain conditions, so the following situation can be avoided, that is, after the desired program is selected, only if the program passes the program's Illustrations, and only after the user's billing is completed, will it be received. In this way, point and manipulate the selector switch 1 3 1 to move the cursor to the desired position. In this way, the command to receive the program specified by Yushu 2 1 2 will be immediately sent to the front-end device 20, and the reception will be initiated. deal with. And finally, before the action of the selection key switch 131 for determining the preset program, the reception processing of the program has already started. Therefore, after the selection button switch 1 3 1 performs the selection and manipulation, the reception of the program has been completed. Even if the reception of the program is not completed, the time that the program is displayed on the monitor 4 is less than that at the time.

Description of Invention (4〇) Display time required. If it is determined in step SP 6 2 that the selection action is a vertical manipulation, step SP 6 3 will then be executed in order to set 0 SD display switching in the register in MP EG video decoder 25, this The action is to switch the window display of the overall guideline. Next, in step S P 6 3, the still image output shown in FIG. 21 and set in step S P 40 is switched. Therefore, the decoding performed after the screen switching starts at step SP 74, and the channel image after the screen switching is immediately displayed as the screen of the desired channel after the static image is eliminated. In the above manner, and in this embodiment, after the overall guidance is displayed, the background image will be a still image that is still. Therefore, when the cursor is moved and the program to be viewed is selected in the overall guidance screen, the overall guidance screen will disappear, and at the same time, the selected channel image will be displayed. In this way, when the program is selected on the overall guidance screen, the background picture is disturbed and unstable. For the above embodiment, when the overall guidance screen is displayed, the channel image that has been displayed will become a still image, and when the cursor moves across the overall guidance, the background image can also be fixed to make it a still image. Figures 23 and 24 illustrate processing examples in this situation.

In other words, In this embodiment, when the overall guidelines are displayed on all sides, the background image will not be converted to a still image, but a dynamic image will be maintained. Next, the program selection process in FIG. 24 will be described. The program selection process is basically the same as the figure The program selection process in 22 is the same, however, for the program process in FIG. 24, step 9 1 will be inserted in step SP67 and step SP69, and step 74 will be inserted in step SP 6 1 and step 9 2 and then, step SP63 The processing in is converted to the processing in step 93, and the other processing in FIG. 24 is the same as the corresponding processing in FIG. 22. Therefore, in this embodiment, the direction of the selector switch 1 3 1 is selected via And control and step Step SP 6 5 'Move cursor' can read the program information corresponding to the button that has been moved in step SP 6 6. Printed by the employee consumer cooperative of the Central Bureau of Standards of the Ministry of Economy if judged in step SP 67 Knowing that the displayed program is set as a pay-per-view program, the setting work of step SP 9 1 will be performed, so that the video output sent to the temporary memory of the PEG video decoder 25 will become a static image, and the MP EG audio The audio output in the register of the decoder 26 is muted. In other words, when the cursor is moved to the key of another program, the motion of the program displayed before the cursor is moved will become a static image and muted. Therefore, in the processing in steps S Ρ 6 9 to S Ρ 7 4, MP EG video decoder 25 and MP EG audio decoder 26 will insert all the keys according to the movement of the player, and perform the program reception and decoding process When these processes are completed, step SP9 2 will be carried out in order to switch the paper size to the Chinese National Standard (CNS) Α4 specification (210Χ297mm) -44-A7 Printed by the Fee Cooperative ___B7__ V. Description of invention (42) The static image setting and mute setting completed in step SP 9 1. Therefore, before the cursor moves, the existing still image will be converted to after the cursor moves Program animation, and the above-mentioned still image corresponds to the key illustration. Then, return to step SP 6 1 to wait for the new input command to be issued by the remote controller 5. If it is judged in step SP 6 2 that the key switch 1 is selected 1 When there is an action, proceed to step SP93 to set 0 SD display switching in the MPEG video decoder 25's temporary memory. This will eliminate the overall guidance that has been displayed and display after the screen switching Animation of the program, and this program corresponds to the displayed key illustration. As described above, in this embodiment, if the cursor moves to a new key icon, a static image is displayed on the background, and the program receiving process corresponding to the key icon of the moving cursor will immediately start to be executed, and when the receiving process After the end, the static image is converted into the corresponding program animation after moving the cursor. Therefore, compared with the previously mentioned embodiment, the user can clearly feel that the program has been switched. Incidentally, in step SP 6 5, if there is an input manipulation to move the cursor to the new button insert before the processing of steps SP 6 6 and SP 9 2 is completed, these processes will be interrupted, Then, the program (channel) processing corresponding to the new key illustration is executed. Then, in the IRD2 shown in FIG. 4, if a program (channel) switching command is input, the switching of still image processing will be performed immediately. The command input is to control the channel up and down key switcher by using the remote controller 5 1 3 3, or press the number switch 1 3 8 to enter the channel, please read the notes on the back of this page. The stupid book size is applicable to China National Standards (CNS) A4 (210X297mm) -45-A7 __ B7 V. Description of the invention (43) No. _. In other words, by manipulating the channel up and down key switch 1 3 3 to enter the command to move the channel up and down, or pressing the number key switch 1 3 8 to directly enter the predetermined channel number, the channel shown in Figure 25 ( Program) switching process will be executed. In step S P 11 1, the received program image is converted into a still image and subjected to sound reduction processing. In other words, each process is set in the registers of MPE G video decoder 25 and MP EG audio decoder 26. Therefore, if the channel switching command is input, the displayed image will become a static image and be muted . Printed by the Employee Consumer Cooperative of the Central Bureau of Economic Affairs of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page). Then, perform steps 1 1 2 to start the reception process of the switched program (channel). In other words, the central processing unit (CPU) 29 controls the front-end device 20 according to the newly input channel and the needs of the demultiplexer 24 to start the reception process of a new channel (switched channel). In step S P 1 1 3, it waits until the switching process ends, and immediately after the switching process ends, step S P 1 1 4 is executed to release the still image and silence processing set in step S P 1 11 1. In other words, what is displayed at this time is the dynamic honey of the channel after switching, and the sound signal with this animation is output. Therefore, during channel switching, it is possible to avoid possible image disturbance and temporary disappearance. Fig. 26 shows other examples of the configuration of the remote controller 5. In this embodiment, instead of the selection key switch 1 3 1 which is operated in 8 directions in the circle 5, the point key switch 2 0 1 to 2 0 4 and Press this button to switch the paper size to the Chinese National Standard (CNS) A4 (210X 297mm) -46-A7 ___B7 printed by the Employee Consumer Cooperative of the Central Standardization Bureau of the Ministry of Economic Affairs V. Invention Description (44) Device 2 0 0, and Point key switch 2 0 1 to 2 0 4 can be used for up, down, left, and right pointing * In addition | In this embodiment, the wired key switch 1 4 5 'TV key switch 1 4 6 and DSS key switch 1 4 7 It is operated in dimmed mode, and the light emitting diodes (LEDs) 148 to 150 'used in FIG. 5 are also omitted here. The LEDs (not shown) on the back of the buttons 145 to 1 4 7 are based on the operation Come to light. The other key switches are basically the same as those in Fig. 5, although the arrangement positions are different. In the above embodiment, the cursor is displayed in a preset brightness, color and blinking mode, but it is also possible to use an arrow and other patterns not related to key insertion as a cursor display, the important point is that the cursor can be used to specify a predetermined position Indicator. In addition, in the above-mentioned embodiment, although the selection of the program is performed in the overall index mode, the present invention can also select the program in other modes. In addition, the present invention also describes the application of I RD 2, and this I RD 2 can actually be used in the monitor 4 (TV).
