| Abstract: | Audio data can be embedded in digital video stream for broadcasting. This paper studies the principle of audio embedded in digital HD video according to the SMPTE299M standard, designs and implements the audio demultiplexing system based on FPGA. The system can demultiplex 16 channels audio data sampled at 48K and play out the audio of selected channels which are concerned. It could be used in digital studio for monitoring and playing out the audio in each channel. |
