Abstract: A multimedia data transmission apparatus and method are provided. In the method, a data receiver receives at least one channel of multimedia data and transmits the received multimedia data to a selector and a data synthesis module. The selector selects target multimedia data from the received multimedia data and transmits the target multimedia data to a data processing module. The data processing module performs a format conversion on the target multimedia data to obtain converted data and transmits the converted data to a data transmitting module. The data synthesis module synthesizes the received multimedia data to obtain synthesized data and transmits the synthesized data to the data transmitting module. The data transmitting module transmits the converted data to a first processing device and transmits the synthesized data to a second processing device.

Abstract: A deserializer is provided. The deserializer includes a data receiver, an RCC transmitter, an I2C master, a command determination device, a video transmitter, a video processing device and an I2S transmitter. The data receiver analyzes raw data sent to the deserializer to obtain audio data, video data and/or command data. The I2S transmitter sends the audio data to the outside of the deserializer. The video processing equipment performs a format conversion on the video data and sends the video data to the outside of the deserializer. The command determination device determines the command data, and sends the command data to the outside of the deserializer in response to a determination result indicating that the command data is a deserializer external command.

Abstract: A serializer includes: an I2C controller, an I2C command analysis circuit, a system control circuit, a low-speed data transmission circuit, a high-speed data conversion circuit, a low-speed data processing circuit, a parallel-serial conversion bidirectional circuit, a serial-parallel conversion circuit, a protocol analysis circuit, a video data processing circuit and an I2C receiver. The serializer can receive the external control command from the external controller through the I2C controller, and can also receive the external control command and the internal control command through the parallel-serial conversion bidirectional circuit. In addition, the serializer can also receive the video data from the external video source through the serial-parallel conversion circuit, and receive the audio data from the external source through the I2C receiver. Therefore, the serializer in the present disclosure can be applied to both two application scenarios, which is more flexible in application.

Abstract: An FEC codec module is provided. Code elements, i.e., code words of forward error correction code, are added to the data code stream of each transmission link through the codec module, so that accurate error determination and automatic error correction may be realized at the receiving end. The interleaving process is performed on multi-link data to prevent the occurrence of continuous burst errors in the data link in a transmission process, and the error correction capability of FEC is utilized to improve the data transmission efficiency and anti-interference ability of the system.
