TRANSMISSION METHOD AND DEVICE FOR HDMI AUDIO/VIDEO SIGNAL

摘要

The present invention discloses a transmission method and device for an HDMI audio/video signal. The method comprises: obtaining and decoding an HDMI audio/video input signal to separate and obtain a video signal from an audio signal; if a video signal is received, then performing the next step, and otherwise storing the audio signal; if the video signal is of a next row and is to be flipped, then storing two rows of video signals and outputting the same in a reverse order to perform encoding with the audio signal to generate a first HDMI audio/video output signal, and otherwise, encoding the video signal and the audio signal to generate a first HDMI audio/video output signal; obtaining and decoding the first HDMI audio/video output signal to separate and obtain a video signal from an audio signal; and reading resolution configuration information, and encoding the video signal and audio signal to obtain and output a second HDMI audio/video signal. Implementing the transmission method and device for an HDMI audio/video signal of the present invention can improve viewing convenience for test subjects and flexibly meet demands of different test subjects.
