    • The invention relates to a method and device for buffering data for multiplexing. The invention also relates to a method of multiplexing and to a multiplexer arrangement using the method and device for buffering data for multiplexing. In one embodiment the invention can be applied to the buffering of non-traffic data, such as firmware updates or other supplementary information, before multiplexing the non-traffic data with traffic data, such as television data of television channels, to form a satellite broadcast channel. In embodiments of the invention, non-traffic data for multiplexing is buffered and then read out again for multiplexing at a rate which is a function of buffer fullness. The non-traffic data may be multiplexed with at least one traffic data channel. A multiplexer can view the non-traffic data channel as another multiplexing input and can allocate the available bit rate between the traffic data channels and the non-traffic data accordingly.
    • 本发明涉及用于缓冲多路复用数据的方法和装置。 本发明还涉及使用用于缓冲用于复用的数据的方法和装置的复用方法和多路复用器装置。 在一个实施例中,在将非业务数据与诸如电视频道的电视数据的业务数据复用之前,本发明可以应用于非业务数据的缓冲,例如固件更新或其他补充信息,以形成卫星广播 渠道。 在本发明的实施例中,用于多路复用的非业务数据被缓冲,然后再次读出以以缓冲器充满度的函数的复用。 非业务数据可以与至少一个业务数据信道多路复用。 多路复用器可以将非业务数据信道视为另一复用输入,并且可以相应地在业务数据信道和非业务数据之间分配可用比特率。
