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.

Multimedia data transmission apparatus and method

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.

Deserializer

A data processing method is applied to a digital interface, which includes: reading data cached by a data source, where the data source includes a video source and an auxiliary data source; outputting video data, if the video data cached by the video source is not empty, where when the video data is output, corresponding position marks are at start and end positions of a frame structure of the video data and at start and end positions of a row structure of the video data; and outputting auxiliary data, if the video data cached by the video source is empty, the auxiliary data cached by the auxiliary data source is not empty and the frame structure or the row structure of the video data has been output, where when the auxiliary data is output, corresponding position marks are at a start position and an end position of the auxiliary data.

Data processing method and device

A control method and device for bidirectional communication are provided. A handshake between the master and slave communication units is realized by sending the training sequence. The master communication unit is controlled to obtain control information from the ECU. The control information is packaged into the custom package, and the custom package is encoded. The master communication unit is controlled to send the custom package to the slave communication unit. The slave communication unit decodes, verifies and corrects the custom package. The slave communication unit feeds back the correct message to the master communication unit if the custom package is verified to be correct, else feeds back the error message to the master communication unit. The master communication unit resends the custom package to the slave communication unit if it receives the error information or does not receive any feedback information within the preset time period.

Control method and device for bidirectional communication

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.

A conversion apparatus, a storage device and a method for manufacturing the same are provided. The storage device may include a DDR storage layer, a DDR interface layer, a conversion logic circuit layer, and a peripheral interface layer. The peripheral interface layer may include a GDDR interface layer or a PCIe interface layer. The conversion logic circuit layer may process, by using DDR storage logic, data obtained through the peripheral interface layer and transfer processed data to the DDR interface layer, or process, by using GDDR storage logic, data obtained through the DDR interface layer and transfer processed data to the peripheral interface Layer. The DDR storage layer may be connected to the DDR interface layer, so that the conversion logic circuit layer can convert the storage logic of the data from DDR to GDDR or from GDDR to DDR.

A signal extension system is provided according to the present disclosure, which includes: a transmitting side chip and a receiving side chip connected to the transmitting side chip. The transmitting side chip is configured to receive high-definition video data and transmit the high-definition video data to the receiving side chip after performing first color space conversion, low compression, parallel-serial coding on the high-definition video data sequentially. The receiving side chip is configured to receive the high-definition video data transmitted from the transmitting side chip and output the high-definition video data to a display device for display after performing serial-parallel decoding, low decompression, and second color space conversion on the received high-definition video data. With the above signal extension system, a transmission distance of the high-definition video data is extended.

Signal extension method and system

A method and a system for encrypting a data stream are provided. The method includes receiving a multimedia data stream including multiple data elements; dividing the multimedia data stream into M data sub-streams based on sequence of the multiple data elements in the multimedia data stream, where the M data sub-streams follow a synchronous clock period which is M times of a clock period of the multimedia data stream, where M is a positive integer greater than 1; and generating a key at a predetermined time interval with a new pipeline algorithm, and encrypting the data elements in the M data sub-streams with the key and the complicated control logic, and the predetermined time interval is N times of the clock period of the M data sub-streams, where N is a positive integer.
