Definitions
- embedding the configuration data for at least one frame data in the previous invalid interval of at least one frame data of the video signal includes: determining the configuration data according to the rising edge or the falling edge of any frame synchronization signal in the previous invalid interval. The starting position of the transmission. Alternatively, the start transmission position of the configuration data is determined according to the rising edge or the falling edge of any row synchronization signal in the preceding invalid interval.
- a display device including: a memory and at least one processor.
- the memory is configured to store instructions.
- At least one processor executes instructions stored in the memory to implement the video signal sending method and/or the video signal receiving method described above.
- a non-transitory computer storage medium that stores computer-readable instructions, wherein, when the computer-readable instructions are executed by a computer, the video signal transmission described above can be executed.
- Method and/or video signal receiving method are provided.
- Fig. 3A schematically shows a format diagram of a video signal according to an embodiment of the present disclosure
- At least one of the “systems” shall include, but is not limited to, systems having A alone, B alone, C alone, A and B, A and C, B and C, and/or systems having A, B, C, etc. ).
- a video signal may include 5 frame data: frame data 1 to frame data 5.
- the configuration data a is embedded in the previous invalid interval of the frame data 1
- the configuration data b is embedded in the previous invalid interval of the frame data 2.
- the receiving end first parses out the configuration data a, and stores the configuration data a in the buffer area.
- the frame data 1 is parsed out, and the frame data 1 is processed based on the configuration data a in the buffer area to obtain the processed pixel data 1.
- the configuration data b is parsed out, and the configuration data b is stored in the buffer area to replace the configuration data a.
- each block of configuration data is transmitted separately based on the rising or falling edge of the line synchronization signal, that is, the data packets are separated from each other, and different data packets can be distinguished directly without passing through the header of the data packet
- the identification and the tail mark can be used to distinguish, which can save the amount of transmitted data.
- the present disclosure also provides a computer-readable storage medium.
- the computer-readable storage medium may be included in the device/device/system described in the above embodiment; or it may exist alone without being assembled into the device/ In the device/system.
- the aforementioned computer-readable storage medium carries one or more programs, and when the aforementioned one or more programs are executed, the video signal sending method and/or the video signal receiving method according to the embodiments of the present disclosure are implemented.
