Abstract

The invention discloses digital composite TV set based on tuner, memory, decoder, and output device. Moreover, the disclosed TV set also includes following two parts: control device, and 1394 control device. Controlling input signal, determining whether input signal can be stored, the said control device stores the input signal to the memory or digital video home system (DVHS) as well as can output signal stored in DVHS or store signal in memory. Converting transmission stream sent from the said control device, 1394 control device makes transmission stream accord with 1394 protocol, and sends it to DVHS, or converts signal from DVHS to transmission stream, and sends it to the said control device. Besides playing digital TV program, the discloses structure possesses function for inputting each source as well as makes composite product capable of recording and storing various signals utilize 1394 port so as to possess additional functions.

Description

technical field [0001] The present invention relates to a digital composite television receiver. In more detail, this digital composite television receiver can store the television media of such various channels in a built-in digital signal receiving device receiving digital television, analog television and external input. DVHS (Digital Video Home System: Digital Video Recorder) with port 1394, or store the data stream stored in the DVHS on the storage medium in the receiving device, and back up the data stream stored in the receiving device to the DVHS. Background technique [0002] Recently, as ground wave receivers become more popular and advanced, ground wave receivers are gradually becoming more complex, and various products are appearing. Among them, video recorder (PVR: Personal Video Recorder) has become a hot topic among people. [0003] PVR is a digital video recorder that records information on a hard disk and plays this information. It is different from a video...
