    • The present invention discloses a method and a device for detecting a primary synchronization signal and generating a sequence in a LTE system, so as to solve the problem that the overhead for 3GPP LTE system to store a local primary synchronization sequence is too much during the initial cell search process. The method for detecting a primary synchronization signal includes: directly generating a local primary synchronization signal sequence with equal amplitude in the time domain as a matched filter; performing a front-end processing for a received signal; performing the matched filtering between the received signal after the front-end processing and the local primary synchronization signal sequence; judging the output amplitude of the signal sequence obtained after the matched filtering; and then obtaining a judgment result of the local primary synchronization signal sequence.
    • 本发明公开了一种用于检测主同步信号并在LTE系统中生成序列的方法和装置,以解决在初始化期间3GPP LTE系统存储本地主同步序列的开销太多的问题 小区搜索过程。 用于检测主同步信号的方法包括:在时域中直接产生具有相等振幅的本地主同步信号序列作为匹配滤波器; 对接收到的信号执行前端处理; 在前端处理之后的接收信号与本地主同步信号序列之间执行匹配滤波; 判断匹配滤波后得到的信号序列的输出幅度; 然后获得本地主同步信号序列的判断结果。

    • A set top box apparatus, a system and a method for implementing Internet Protocol Television (IPTV) channel recording and playing are disclosed in the present invention. The set top box apparatus is configured to: store information of channels and playing addresses of the channels downloaded from an Electronic Program Guide (EPG) server; when receiving a channel recording and/or channel switching command of a user, acquiring a corresponding playing address according to a channel selected by the user, and acquiring a media stream of a channel program corresponding to the playing address from a media server for recording or playing; when the user needs to record and play simultaneously in a same procedure, the set top box apparatus switches the recording to be performed in a background, and set the playing to be performed in a foreground. The invention implements a humanized channel recording function.
