摘要： An in-band signaling method and apparatus of a mobile broadcast system supporting irregular interval broadcast services is provided for facilitating channel switching of a mobile device. An in-band signaling method for a mobile broadcast system according to the present invention includes generating scheduling information of Physical Layer Pipes (PLPs) transmitted at irregular intervals, the scheduling information including a next frame index and a first frame flag, inserting the scheduling information into a control information of a current frame and multiplexing broadcast service traffic of the PLPs and the control information.

摘要： A Digital Video Broadcasting-Cable (DVB-C) system and a processing method for reserved tones are provided. A transmitter determines a position of broadcast data and a position of reserved tones in a frame and sends a broadcast signal into which the broadcast data and the reserved tones are inserted. A receiver determines the position of reserved tones in a received broadcast signal and extracts broadcast data from the broadcast signal in consideration of the determined position of the reserved tones. The system and method may compensate for the peak power of broadcast data to be transmitted through a multi-channel bundle, by inserting reserved tones into the whole multi-channel bundle with combined channel bands. This may reduce the Peak to Average Power Ratio (PAPR) of broadcast signals in the DVB-C system and thereby improve the performance of the DVB-C system while still adopting Orthogonal Frequency Division Multiplexing (OFDM).
摘要翻译：提供数字视频广播电缆（DVB-C）系统和用于保留音调的处理方法。发射机确定广播数据的位置和帧中的保留音调的位置，并发送广播信号，广播数据和保留音被插入到该广播信号中。接收机在接收到的广播信号中确定保留音调的位置，并考虑到所保留的音调的确定位置，从广播信号中提取广播数据。该系统和方法可以通过将保留的音调插入到具有组合信道频带的整个多信道束中来补偿要通过多信道束发送的广播数据的峰值功率。这可能降低DVB-C系统中广播信号的峰均功率比（PAPR），从而提高DVB-C系统的性能，同时采用正交频分复用（OFDM）。
