Embodiment Construction

[0037] The method for recording transport stream data and its playback control method according to the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Fig. 2 is a schematic structural diagram of a DVD RW and PVR combination machine in an embodiment of the present invention.

[0039] As shown in Figure 2, the structure of the present invention consists of the 1st module 100 with PVR function, the 2nd module 130 required for DVD media storage and playing data, the interface device (dual port) that connects the 1st module 100 and the 2nd module 130 random access memory (DPRAM) 120.

[0040]The above-mentioned first module 100 transmits the demodulated transport stream (TS: Transport Stream) to the encrypted The stream controller (TScontroller) 103 in the transport stream (ETS: Encryption TS) of processing, the bus bridge (PCI / IDE Busbridge) 105 that is connected on the system bus (PCI bus), transmits by the bus bridge 105...

Abstract

This invention relates to data transmission record and play control method, which can record data flow onto other module disc medium in digital play product and relates to the record and play control method technique. This invention can process demodulate and coding on the play signals received from tuner and demodulator in the combination set of PVR and DVD module and record its buffer process into DVD media and then read and record the data flow and process demodulation process and play at the image coder.

Description

technical field [0001] The present invention relates to the technology of recording transport stream data and its play control method, which can record transport stream into optical disk media installed on other modules in digital broadcast products, and play it. Background technique [0002] Generally speaking, a digital broadcast signal receiver uses a HDD (Hard Disc Drive) as a storage medium in the process of storing and playing a received data stream (Data stream) or playing 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 (Demodulator) 2 that can receive broadcast signals from any service medium and output digital data, and a pair of slave tun...
