Abstract: An Internet Protocol Television (IPTV) broadcasting system is provided. The IPTV broadcasting system includes: An Internet Protocol Television (IPTV) broadcasting system for reducing a display delay when a channel is changed, including: a stream transmitting apparatus receiving a broadcast channel stream, generating an acceleration stream from the broadcast channel stream, and transmitting the broadcast channel stream and the acceleration stream; and a set-top box receiving the broadcast channel stream and the acceleration stream from the stream transmitting apparatus, and reproducing a decoding stream, according to a type of a received frame in the broadcast channel stream and the acceleration stream. Therefore, it is possible to reduce a display delay when a channel is changed.

Abstract: The present invention is directed to a scheduling method for processing at least two channels in a VoP (Voice over Packet) system. The VoP system according to the present invention includes a packet buffer for temporarily storing packets transferred from a packet network; a DSP (Digital Signal Processor) for processing algorithm modules of at least two channels; a scheduler for scheduling a channel to be executed by the DSP every cycle, and controlling the DSP to execute an algorithm module having a fixed execution time among the algorithm modules of the channels, and then an algorithm module having a variable execution time; and a TDM (Time Division Multiplexing) buffer for input/output to/from the TDM network.
