The invention discloses a digital television set-top box distribution system PSI/SI table data, including the demuxing module, the demuxing module according to the user's request to receive digital TV TS stream formation section of the corresponding data packet, which is characterized in that the demuxing module connection section processing module and buffer module are described. The demuxing module will throw some piece of data packet processing module; section processing module open space to store the demuxing module thrown in the set-top box memory data packet queue, segment packet table number to create the buffer module according to the data, the same PSI/SI table ID and PID packets stored in the buffer module, and splicing, delete the redundant information, the data will be formed after stitching final PSI/SI transfer to the user table. The system improves the processing ability of STB to section data.
【技术实现步骤摘要】
【技术保护点】
一种数字电视机顶盒的ＰＳＩ／ＳＩ表的段数据分发系统，包括解复用模块，所述解复用模块根据用户的请求接收数字电视ＴＳ流形成相应的段数据包，其特征在于所述解复用模块依次连接段处理模块、缓冲模块，所述解复用模块将段数据包抛给段处理模块处理；段处理模块在机顶盒内存开辟空间存储解复用模块抛出的段数据包队列，根据段数据包的表号创建缓冲模块，将相同ＰＳＩ／ＳＩ表ＩＤ、ＰＩＤ的段数据包存储在缓冲模块内，并进行拼接处理，删除冗余信息，将拼接后的段数据形成最终ＰＳＩ／ＳＩ表传递给用户。
