    摘要： A multiplexed transport interface (MTSIF) may be utilized during communication between a demodulation module and a video processing system-on-chip (SoC). The MTSIF may enable concurrent demodulation of a plurality of input modulated video streams, via a plurality of demodulator chips within the demodulation module, by multiplexing data generated by the demodulator chips via the MTSIF during communication between the demodulator module and the video processing SoC. The MTSIF may also be utilized for communicating control signals, which may be used in controlling and/or managing operations of the demodulation module, the video processing SoC, and/or the MTSIF. Communication via the MTSIF may be synchronized. Packets communicated via the MTSIF may be timestamped. Timestamp counters may be used in the demodulation module and the video processing SoC to generate and/or track timestamps in communicated packets. The timestamp counter may be synchronized, using control signals communicated via the MTSIF.

    摘要： The present disclosure relates to the field of communication technologies, and discloses a method for and system of vehicle-carried audio and video transmission, a vehicle-carried terminal and a server. The method comprises the following operations: the vehicle-carried terminal acquiring an audio and video transmission request transmitted by the user, establishing a connection with the server through a plurality of physical links according to the audio and video transmission request, receiving a plurality of audio and video data packets transmitted by the server, merging the plurality of audio and video data packets into one audio and video data stream and decoding the audio and video data stream and outputting the decoded audio and video data stream. Through the plurality of physical links between the vehicle-carried terminal and the server, the plurality of audio and video data packets transmitted by the server can be received and finally the plurality of audio and video data packets are merged into one audio and video data stream. Compared with the method of transmitting one audio and video data stream through one physical link in the prior art, the embodiment of the present disclosure has the advantages that the vehicle-carried audio and video transmission speed is improved and the transmission speed is higher when the physical links are more.

    摘要： The present invention relates to a data processor and data processing method that facilitate properly processing a stream. An input stream is formed by a plurality of packets. Each of the packets of the input stream is distributed to one of a plurality of channels and null packets (NP) are distributed to the other channels. This divides the input stream into divided streams on a plurality of channels including the packets of the input stream at a predetermined density. The present invention can be used, for example, for a channel bonding (CB) technique in which an input stream is divided into a plurality of channels and transmitted.
