Method and system for multiplexed transport interface between demodulators (DEMODS) and set-top box (STB) system-on-chips (SOCS)

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.
