    摘要: Provided is a method and system for transmitting MPEG frames between a DOCSIS based satellite modem termination system (SMTS) and a corresponding satellite modem (SM) system. The method includes identifying at least one data stream requiring transmission between the SMTS and the SM, the data stream including one or more MPEG frames. Next, the MPEG frames are organized within SMTS data queues based upon predetermined parameters and then transmitted based upon their organization within the data queues.

    摘要: Provided are a method and system for determining system time in a satellite based cable data communication system. The system includes a satellite modem termination system configured to transmit data frames to a receiver in a predetermined symbol rate. Each frame includes a corresponding number of symbols and has a time stamp (i) indicative of the frame's time of transmission and (ii) positioned within the frame at a location common to all of the frames. The method includes receiving at least two consecutively transmitted data frames within the receiver and registering the time stamp of the first received data frame within the receiver to produce a first time stamp. Also, the time stamp of the second received data frame is registered within the receiver to produce a second time stamp. The time of transmission of the second transmitted data frame is updated, wherein the updating is a function of the first time stamp, the second time stamp, the corresponding number of symbols, and the symbol rate.

    摘要: Provided are a method and system for processing at least two consecutive MPEG Q-blocks in a communications system, one of the Q-blocks being low rate and the other being high rate. The method includes back-filling an empty portion in a first transmitted Q-block with a first portion of second type data, the remaining portion of data of the second type data being included in another Q-block prior to transmission. The second type data crosses a boundary between the first and the other Q-block when the actual number is less than a corresponding maximum number. Finally, the method includes receiving within an associated subscriber modem one of the first and the second type data and not receiving the other of the first and the second type data when the second type data crosses the boundary.
