Abstract

The embodiment of the invention discloses a screen recording method and a touch television. A signal processing device is arranged between a television mainboard and a display screen. The signal processing device receives a video signal and an audio signal from the television mainboard. The signal processing device splits the video signal into a first video signal and a second video signal. The signal processing device transmits the first signal to the display screen. The signal processing device carries out hybrid coding on the second video signal and the audio signal, thereby obtaining a coding signal. The signal processing device transmits the first coding signal to a video recording device through a recording signal output port. Before the video signal is transmitted to the display screen, the video signal is transmitted to the signal processing device; after the signal processing device receives the video signal and the audio signal, the coding signal is output to the video recording device; therefore, the recording image effect is improved; and moreover, the occupation of the processor and memory resources on the television mainboard is reduced.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a screen recording method and a touch television. Background technique [0002] With the continuous development of TV technology, touch TV has been integrated into people's life. Such as figure 1 As shown, the touch TV includes a TV main board 1 and a display screen 2 the same as a traditional TV. The TV main board 1 is provided with a processor 3 , a video signal output terminal 4 and an audio signal output terminal 5 . Processor 3 is used for processing video and audio signals received through wired or wireless. The processed video signal is transmitted to the display screen 2 of the touch TV through the video signal output terminal 4 for playback, and the audio signal is transmitted to the external device of the touch TV through the audio signal output terminal 5 to play synchronously with the video signal. However, different from traditional TV sets, the display screen ...
