Technical Field
The invention relates to the field of audio processing, in particular to a network distributed seat system and an audio processing method based on the system.
Background
As shown in fig. 1, in the prior art, a conventional audio function of the network distributed agent system is to output the input audio of the agent coding box to the agent decoding box. If the audio is required to be subjected to professional audio processing, the output audio is required to be input into the professional audio processor system from the seat decoding box, and is input into the power amplifier or the sound box for output after being subjected to professional audio processing through the external professional audio processor system.
Generally, an audio processor mainly has functions of audio matrix switching and professional audio processing. The general network distributed agent system has the function effect of standby frequency matrix switching, and is repeated with the function of an audio matrix in a professional audio processor, so that the functions are repeated, and the cost is redundant.
In addition, because the audio signals are required to be additionally input into the professional audio processor for professional audio processing, the video signals and the audio signals in the seat decoding box pass through different processors, so that the synchronization of the audio signals and the video signals is difficult to ensure, and the experience is influenced.
Moreover, for the network distributed agent system, when there are few agent devices or items with more agent devices but only a small amount of signals are required for audio processing, the cost of configuring the professional audio processor is too high, and the functions cannot be realized because the professional audio processor is not configured.

The invention directly implants the audio processing chip in the agent coding box and the agent decoding box of the network distributed agent system, wherein the audio processing chip is an audio processing chip with reduced functions, has only an audio processing function and does not have an audio matrix switching function, so that the invention avoids the repetition of the original audio matrix switching function in the agent coding and decoding box, avoids the functional redundancy, and simultaneously can improve the adaptation compatibility of the audio processing chip and the agent coding and decoding box. Because the audio processing chip is reduced, the cost is lower, and the number of seat coding boxes and the number of seat decoding boxes which are required to be implanted into the audio processing chip can be determined according to actual needs, so that the flexibility of system layout is improved.

In the network distributed seat system, for the seat codec box with the built-in audio processing chip, the seat codec box inputs the audio signals in the received audio and video signals to the audio processing chip for audio processing, so that the quality of the audio can be improved.
In the above scheme, before the audio signal after the audio pre-stage processing and the video signal in the audio and video signal are output to the switch together, the audio processing chip in the seat coding box and the audio signal after the audio pre-stage processing are also subjected to delay correction, the seat coding box synchronously performs delay correction on the video signal in the audio and video signal, and the audio signal after the synchronous delay correction and the video signal are output to the switch together.

And for the seat decoding box without the built-in audio processing chip, after receiving the audio and video signals, the seat decoding box decodes the audio and video signals, and after decoding, the seat decoding box does not perform professional audio processing on the audio signals, but outputs the decoded audio and video signals.
In this process, the seat decoding box still has its original decoding function, but when the audio processing chip is built in, the audio signal obtained after decoding needs to be input into the audio processing chip for professional audio processing, and then the decoded video signal and the audio signal processed by the professional audio processing are output. The whole system structure does not need to greatly improve the seat decoding box, and the built-in audio processing chip can assist the seat decoding box to complete relevant professional audio processing.
In the implementation process, because only the audio signal is input to the audio processing chip for professional audio processing in the audio/video signal input to the seat decoding box, and the video signal is not processed in a related manner, the audio/video in the seat decoding box is easy to be asynchronous. And by adding delay correction, the video signals and the audio signals output by the seat decoding box can be ensured to be synchronous without delay.
