Description

【Technical field】 [0001] The present invention relates to the technology of a transport stream data control system capable of recording and reproducing HD (High Definition) transport streams into DVDs in digital broadcasting products. 【Background technique】 [0002] Generally, a digital broadcast signal receiver uses a HDD (Hard Disc Drive) as a storage medium when storing a received data stream (Data stream) and reproducing it, or reproducing it while storing it. For this reason, the main features and structure of the digital broadcast signal receiver are shown in Figure 1. [0003] FIG. 1 is a schematic structural diagram of a conventional digital broadcast signal receiver. [0004] As shown in Figure 1, the digital broadcast signal receiver is composed of the following structure: that is, a tuner (Tuner / Demodulator) 2 that can receive broadcast signals from any service medium and output digital data, and a pair of slave tuners A code stream controller 4 for adjusting th...
