Broadcast television is a news-dissemination tool that disseminates sound, images, video over radio waves or wires. The broadcast television operator transmits the program by setting different frequency points. The broadcast operator may send the same program, i.e., a repeat program, at different frequency points. In the current mainstream television protocol stack processing scheme, repeated programs are not reasonably utilized.

In the currently mainstream television protocol stack processing scheme, there are generally two ways to process repeated programs:

the first way is to save the repeated program if it is searched during the channel searching process, and display the repeated program in the channel list. The television traverses the programs displayed in the channel list as they play the programs. If there are duplicate programs in the channel list, the time spent traversing the channel increases and the experience is poor for the user.

The second way is to discard the repeated program if it is searched during the channel searching process. Only one of the repeated programs is reserved. Only one of the repeated programs is also displayed in the channel list. This approach, while reducing the number of programs on the channel list, shortens the duration of completing a turn. But the repeated program is not effectively utilized because the repeated program is discarded in the channel searching process.

In addition, when the broadcast signal transmitting end fails to cause the program of a certain frequency point to stop transmitting, the program is interrupted to play, so that the viewing experience of a user is poor.

In order to solve the above problems, the present application provides a display apparatus, in which a user can input a control instruction using a control device or input a control instruction by voice.

After the user opens the display device, a control instruction to start searching the channel may be input, and the display device starts searching the channel, i.e., searches the program, in response to the control instruction. According to the method and the device, programs are searched according to the frequency points, and after all the programs are searched, all the searched programs are stored in the program storage file.

In some embodiments, the specific process of saving the searched program to the program storage file is:

the frequency point N can be searched first, if the frequency point N does not search the program, the frequency point N search is ended, and the next frequency point search is performed. If the frequency point N searches the program M, the program M is stored in a program storage file. Further, searching in the program storage file, whether the program M1 is stored or not. The program M1 and the program M are the same content, and the frequency point where the program M1 is located is different from the frequency point where the program M is located, and the program M1 is a repeated program of the program M. In the program storage file, a repetition mark pointing to the program M may be added on the program M1. Finally, a program storage file example as shown in table 1 can be obtained.

Frequency point 1 program A
	Frequency point 2 program B
Frequency point 3 program A (repetition)
	Frequency point 4 program C

Table 1 program storage file example

The program storage file shown in table 1 includes 4 records, each of which includes two pieces of information: frequency points and program names. Since the program a at the frequency point 1 and the program a at the frequency point 3 are repeated programs, a repeated mark is added to the program a at the frequency point 3. A repetition mark may be added to program a at bin 1. Here, the repeated program searched later adds a repetition mark.

In some embodiments, the display device may generate a playlist from the program storage file obtained by the search, and then display the playlist on the user interface. And displaying all programs obtained by searching channels in the play program list. The user can select a program to be played by controlling the operation device.

In some embodiments, the program content of the first program is played on the display in response to a control instruction from the user selecting the first program in the playlist of programs. When the signal of the first frequency point where the first program is located is interrupted, a second frequency point of the second program is read from the program storage file, and the program content of the second program is played on the display according to the second frequency point. The second program is a repeat of the first program.

For example, the first program may be the program a in the above-described embodiment, and the second program may be the program a (repetition) in the above-described embodiment. When the user selects program a in the playlist, the program content of program a is played on the display. When the signal of the frequency point 1 where the program A is located is interrupted, searching in the program storage file. Finally, according to the repetition mark, finding out the program A (repetition) and obtaining the frequency point 3 of the program A (repetition). Finally, according to the frequency point 3, the program A is played (repeated). Since the program content of the program a and the program a (repeated) are the same, when the signal of the frequency point 1 is interrupted, the program content of the program a can also be continuously played according to the frequency point 3. Not only reasonably utilizing repeated programs, but also improving the watching experience of users.

In some embodiments, the method for determining the repeated program specifically includes: comparing the comparison item content of the first program with the comparison item content of the second program, the first program and the second program being duplicate programs if the comparison item content of the first program and the comparison item content of the second program match perfectly. If the comparison item content of the first program and the comparison item content of the second program cannot be matched perfectly, the first program and the second program are not duplicate programs.

Before matching the comparison item content of the first program with the comparison item content of the second program, it is also necessary to determine the broadcast television system of the first program and the second program. The content of the comparison items of the programs in different broadcast television systems is different.

For example, the comparison items in the DVB broadcast television system include: the network ID (Original Network ID, original network identity), the tsid (Transport Stream ID, transport stream identity), and the sid (Service ID, service identity). If the broadcast television system of the first program and the second program is DVB, when determining whether the first program and the second program are the same program, it is necessary to determine whether the three comparison items are matched with each other. The comparison items in the ATSC broadcast television system include: tsid (Transport Stream ID) and sid (Service ID). If the broadcast television system of the first program and the second program is ATSC, when judging whether the first program and the second program are the same program, it is necessary to respectively judge whether the contents of the two comparison items are matched. The comparison items in the ATSC-T3 broadcast television system include: group ID (Group identification), bsid (Broadcast Stream ID, broadcast stream identification), sid (Service ID). If the broadcast television system of the first program and the second program is DVB, when determining whether the first program and the second program are the same program, it is necessary to determine whether the three comparison items are matched with each other.

In some embodiments, the specific steps of displaying the playlist on the display are:

program information of the stored program is read from the program storage file, and the read program information is sequentially displayed according to the entries. When a program that is not marked with a repetition mark is read, the program is normally displayed in a play program list. When a program marked with a repetition mark is read, the program is not displayed in the play program list.

For example, the program storage file shown in table 1 is read. When the program a of the frequency point 1 is read, since there is no repeat mark, the program a of the frequency point 1 is displayed in the play program list. Similarly, when the program B of the frequency bin 2 is read, since there is no repeat mark, the program B of the frequency bin 2 is displayed in the play list. When the program a of the spot 3 is read, since the recording has a repeat mark, the program a of the spot 3 is not displayed in the play list. The resulting playlist is shown in table 2.

Frequency point 1 program A
	Frequency point 2 program B
Frequency point 4 program C

Table 2 playlist examples

The embodiment can reasonably utilize the repeated programs, avoid the repeated display of the repeated programs in the play program list, shorten the time for completing one-turn channel, and further improve the watching experience of the user.

An embodiment of the present application provides a program saving method, as shown in a flowchart of the program saving method in fig. 6, including the following steps:

step one, starting the channel searching of the frequency point N, and ending the channel searching of the frequency point N if the frequency point N is the searching program.

And step two, if the program M is searched in the frequency point N, continuously judging whether the program which is the same as the program M and has the frequency point not being N is stored in the current program storage file.

And step three, if the program M is not stored in the program storage file and the frequency point is not the program of N, storing the program M searched in the frequency point N into the program storage file as a record.

If the program which is the same as the program M and has the frequency point which is not N is stored in the program storage file, the program M searched at the frequency point N is marked with a repeated mark, namely the program M (repeated), and the marked program M (repeated) is stored in the program storage file as a record.

step one, reading records in a program storage file, and if the recorded program has no repeated mark, displaying the program in a play program list.

And step two, if the recorded program has a repeated mark, the program is not displayed in the play program list.

And step three, after all records in the program storage file are read, ending the display flow of the play program list.

Based on the above embodiments, the embodiments of the present application further provide a content display method, such as a flowchart of the content display method shown in fig. 8, where the method includes the following steps:

step one, in response to a control instruction of selecting to play a first program in a play program list, playing the program content of the first program on a display.

And step two, when the signal of the first frequency point where the first program is located is interrupted and a second program exists in the program storage file, reading a second frequency point of the second program from the program storage file, and playing the program content of the second program on the display according to the second frequency point. The first program and the second program are the same program, and the first frequency point and the second frequency point are different frequency points.

And step three, when the signal of the first frequency point where the first program is located is interrupted and the second program does not exist in the program storage file, ending the program playing process.
