Abstract
A transmission method, apparatus, and system implement bidirectional transmission of an audio/video signal between peer devices. The transmission system may include a first transmission apparatus and a second transmission apparatus, where the first transmission apparatus is connected to the second transmission apparatus through a first cable, and the first cable includes a first number of main downlink lanes and a second number of main uplink lanes. Bidirectional transmission of the audio/video signal between the first transmission apparatus and the second transmission apparatus is performed through the first cable.
Claims20
An apparatus comprising:
- a processor;
- a first port configured to connect to a second transmission apparatus through a first cable, wherein the first cable comprises a first number of main downlink lanes and a second number of main uplink lanes;
- a first audio/video source adapter configured to:
- obtain a downlink media signal, wherein the downlink media signal comprises at least one of a downlink video signal or a downlink audio signal;
- encapsulate the downlink media signal to obtain a first downlink packet;
- and
- send the first downlink packet;
- a first multiplexer configured to:
- receive the first downlink packet from the first audio/video source adapter;
- pad the first downlink packet into a downlink data stream to obtain a padded downlink data stream;
- and
- send the padded downlink data stream;
- a first lane allocator configured to:
- receive the downlink data stream from the first multiplexer;
- allocate the downlink data stream to a first main downlink lane of the main downlink lanes;
- and
- send the downlink data stream to the second transmission apparatus;
- a first lane deallocator configured to:
- receive an uplink sub-data stream from the second transmission apparatus through a first uplink lane of the main uplink lanes;
- combine the uplink sub-data stream into an uplink data stream;
- and
- send the uplink data stream;
- a first demultiplexer configured to:
- receive the uplink data stream from the first lane deallocator;
- extract a first uplink packet from the uplink data stream;
- and
- send the first uplink packet;
- and
- a first audio/video sink adapter configured to:
- receive the first uplink packet from the first demultiplexer;
- and
- decapsulate the first uplink packet to obtain an uplink media signal.
