Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The signal source control method according to the preferred embodiment of the present invention, as shown in fig. 1, includes the following steps:
and step S10, the display terminal establishes communication connection with a plurality of signal source devices, and the display terminal detects whether the signal source devices are accessed in real time.
Specifically, the display terminal may be an intelligent terminal device, such as a smart television, a smart display screen, a player only, and the like, and the signal source device may be a DVD, a smart phone, a game console, a set-top box, and the like.
Firstly, in order that the display terminal can communicate with a plurality of signal source devices, the display terminal establishes communication connection with the plurality of signal source devices through adding a channel, wherein the channel can be a control line (cable) and a space through which electric waves propagate, for example, the channel can establish communication connection with the plurality of signal source devices (for example, a smart television is respectively connected with a set top box and a DVD) through adding a control line (wired connection), specifically, for example, the invention can adopt one line as the control line, the control line of each signal source can be directly connected into the display terminal (for example, a smart television), the display terminal uniformly manages the control lines, for example, an AV signal (a video signal transmitted through the AV terminal) is originally composed of three lines of a video signal line and left and right audio signals, the AV signal is composed of 4 lines after adopting the scheme of the invention, and the lines are usually communicated with each other at the display terminal, and only can be inquired when the signal source devices are identified, therefore, in order that the control line can respond in time, the control line is a control line of 100KHz or a control line can be implemented at a high speed, and the speed is realized in the cable. In addition, the channel may be a wireless connection, such as bluetooth or wi, and the wireless connection is a space through which radio waves propagate, which may also achieve the purpose that the display terminal establishes communication connection with a plurality of signal source devices by adding a channel, and the present invention is preferably a control line based on the consideration of response speed.
Further, when the display terminal detects that the control line of the signal source device is set to a low level (0V), the signal source device is identified and determined by sequentially switching each signal source, that is, by separately isolating each signal source, for example, the display terminal performs sequential switching by controlling to switch on the control line, respectively identifies and determines each signal source device, for example, controls to switch on a corresponding communication link between the current signal source device and the display terminal, and controls to switch off a communication link between all external signal source devices except for an external signal source device corresponding to the channel and the display terminal, so that the display terminal can detect the signal source device on which the current communication link is switched on, thereby determining which signal source is switched on.
Further, the display terminal assigns a unique address to each of the signal source devices accessed, and is used for identification according to the assigned address (the address has uniqueness) during communication control. The display terminal is provided with a plurality of common signal sources, preferably, the invention can allocate addresses to 15 signal source devices which are accessed at most, for example, the addresses are represented by 4-bit binary numbers, from 1 to 15, and the address 0 is used for broadcasting; after the signal source equipment is accessed, the display terminal distributes a unique address to the signal source equipment for communication control.
And step S20, after the display terminal detects that the signal source equipment is accessed, the display terminal acquires the remote control type of the signal source equipment.
Specifically, the present control device mainly implements wireless control through a remote controller (controller), where the controller in the present invention uses the remote controller as an example, and remote control keys for controlling the signal source device are divided into two types, one is a global key, such as a source key, and can respond through the display terminal at any time, and the other is a compound key, where the current key function is determined according to different sources, such as a number 5, and is used for inputting a channel number when a TV source, and may be defined as playing when an AV source.
The controller, for example, a remote controller, generally displays functions of keys through silk-screen printing, such as number 5, and for a composite key, in order to facilitate use of the composite key, different functions need to be silk-screen printed, and then if silk-screen printing of the remote controller can also be displayed, displayed contents are adaptive to different scenes.
Therefore, after the signal source device is connected (i.e. the signal source device is connected to the display terminal), the display terminal obtains the remote control type specified by the controller protocol of the connected signal source device.
And step S30, after the display terminal is switched to the signal source of the signal source equipment, the display terminal is converted into a mode which is suitable for the remote control type of the signal source equipment according to the signal source, and a key instruction of a controller is forwarded to the signal source equipment.
Specifically, when the display terminal cuts to the source of a certain signal source device (for example, four signal source devices are connected with the display terminal, namely, a DVD, a smart phone, a game machine and a set top box respectively, for example, the currently connected signal source device is the set top box), the remote control type of the signal source device (for example, the set top box) is automatically adapted, and a key instruction (for example, a key instruction of a remote controller, different keys represent different instructions) is forwarded to the signal source device, so that one controller (remote controller) can control different signal source devices.
The key instruction may include a device code, a key value and a check code, and the transmission mode may be completed according to a NEC code protocol (i.e. NEC infrared coding protocol).
The communication protocol can select according to standardized keys and functions of different controllers of the signal source equipment, such as a remote controller of a smart television, a remote controller of a DVD, a remote controller of a set top box and the like, and for facilitating equipment selection, each type of remote controller can be divided into a simplified type and a full-function type. The controller can also be customized to accommodate the new device. After the type of the signal source equipment is identified, the display terminal can acquire the accessed controller information of the signal source equipment.
Further, the display terminal queries the accessed signal source equipment at intervals of preset time, sends a query instruction to the signal source equipment, and judges whether the signal source equipment is in a connection or disconnection state according to whether the signal source equipment responds to the query instruction; when the signal source equipment is detected to respond to the query instruction, judging that the signal source equipment is in a connection state; when the signal source equipment is detected to not respond to the query instruction, judging that the signal source equipment is in a disconnection state; in addition, when the display terminal is overtime and is not queried, the signal source equipment is judged to be in a disconnection state.
That is, the display terminal queries the accessed signal source device at preset time intervals (for example, 1 second and 2 seconds, the time may be set according to specific requirements), for example, the display terminal transmits the query command to the signal source device at intervals of 1 second, and determines whether the signal source device is in a connected or disconnected state according to whether the signal source device responds (responds). And when the display terminal is overtime and is not queried, the signal source equipment can be judged to be in a disconnection state.
Further, when the display terminal identifies the signal source devices and then enters a normal communication state, switching control between the signal source devices can be performed, so that a single controller can control different signal source devices.
Because the display terminal and the signal source equipment can mutually communicate, besides the control of the display terminal for controlling the controller for replacing the signal source, the display terminal can also replace the signal source to display OSD (namely, the menu of the DVD is automatically switched to the signal source by television display, namely, the DVD is accessed when watching television, and the signal source is automatically switched to the signal source of the DVD), thereby realizing the functions of automatic switching of the signal source playing, one-key standby and the like.
The invention realizes the control connection between the display terminal (intelligent television) and the signal source equipment, and controls a plurality of signal source equipment by a single controller (such as a remote controller) according to different scenes or user selection by adding a control channel between the display terminal and the signal source equipment; the user does not need to change the controller because of the different signal source equipment of control, and the user uses more conveniently, because use control channel, need control communication standard, have the standard controller just can peel off from the annex of equipment, realize the diversified demand of controller.
Meanwhile, the user can conveniently operate different devices, the operation of different signal source devices can be realized without changing different controllers by the user, and the number of controllers of the user is reduced; the controller can be separated from the accessory position of the equipment, so that more choices are given to the user, and different requirements of the user are met; and automatic identification can be realized when the signal source is accessed.
