The present invention relates to a digital television receiver having a temporary recording function and a temporary recording method using the same. More specifically, when the digital broadcasting receiver stops watching TV for a while, the broadcast stream is temporarily stored according to a user input. A digital television receiver having a temporary recording function for providing a stored broadcast stream to a user according to a user's input, and a temporary recording method using the same.

Digital TV (DTV) can be defined as a TV broadcasting system that processes all stages of broadcasting such as production, editing, transmission, and reception into digital signals of 0 and 1, and this is the kind of information (video, audio, text). Etc.), which is contrasted with analog TV processing with different signals.

Conventional TVs are all analog systems, which continuously process radio signals over time, so that image quality and sound quality are not clear and only a limited channel can be viewed. On the other hand, digital TV is a high-tech TV that converts an analog signal into a digital signal and adjusts it by a computer circuit, and removes noise such as interference of other radio waves, and can variously select various information (multi-function) and programs. Due to the advantage of being able to reproduce various advanced images (high quality), the digitization of current analog TV broadcasting is accelerating in each country.

1 is a block diagram of a digital TV receiver according to the prior art.

As shown, a digital TV receiver according to the prior art includes a digital broadcast tuner 110, a demultiplexer 120, an A / V decoder 130, a display device 140, a DAC 150, And a speaker 160.

The digital broadcast tuner unit 110 receives the desired broadcast signal and generates an MPEG-2 TS.

The demultiplexer 120 demultiplexes the received MPEG-2 TS to generate an elementary stream (ES) including an audio signal and a video signal.

The A / V decoder 130 decodes the ES to generate an audio signal and a video signal. In this process, the audio signal and the video signal are synchronized.

The generated audio signal is analog-converted in the DAC 150 and output through the speaker 160, and the generated video signal is output through the display device 140.

It also includes components such as a user interface unit (not shown) for receiving a user's input, but a detailed description of the configuration of such a digital TV receiver is omitted in many patents and related technical documents.

In the case of watching a conventional digital TV, a part of the broadcast content may be missed when the user leaves a room for a while while watching a broadcast. In this case, if the receiver has a built-in PVR system or a digital TV receiver connected to the PVR system, it is possible to store the broadcast in advance before leaving the space through the PVR function or to watch the stored broadcast stream again using the time shift function. It may be configured.

However, even in this case, if the user cannot watch for a while, the user can use the time shift or the recording / playback function to retry, but at any point in time, the user may be away from the broadcast stream. If there is no accurate information, simply save the broadcast stream unconditionally and then the user must find the part which he / she did not watch through the search of the broadcast stream and re-view from the corresponding part, or watch it while moving the stream using the jump function. There is this. In addition, since such a PVR is configured to store an ES, a number of components must be added to implement a PVR or time shift, which results in an increase in the price of a digital TV receiver.

Therefore, there is a growing need for a method of temporarily storing a broadcast stream for a case where such a user is away for a short time at a low cost and providing it when the user wants to watch again later.

An object of the present invention is a digital television having a temporary recording function of temporarily storing a broadcast stream according to a user's input and providing the stored broadcast stream to a user according to a user's input when the digital broadcasting receiver stops watching TV for a while.
