The present invention relates to a digital broadcast receiver, and more particularly, to a log file management method and apparatus of a digital broadcast receiver for storing and managing a log (log) containing an operation problem of the digital broadcast receiver.

Generally, digital broadcasting includes digital satellite broadcasting, terrestrial broadcasting, and cable broadcasting. In a digital broadcasting receiver such as a set-top box (STB) that receives the digital broadcasting, a digital broadcasting signal of an MPEG transport stream is used. After receiving the audio signal, the video and audio signals are decoded and processed into the original video and audio signals, and the video and audio signals are transmitted to a television or the like to watch a broadcast program desired by the user.

1 shows an example of a satellite and a television connected to the digital broadcast receiver 300. As shown, the satellite broadcast antenna 200 may be connected to the digital broadcast receiver 300 in order to receive digital satellite broadcasts transmitted through a plurality of broadcast satellites 100, 101, and 102, for example. The digital broadcasting received through the satellite broadcasting antenna is viewed through a television connected to the set top box 300.

And if the same problem as the one previously occurred in the reproduction test is reproduced, it is possible to trace and improve the cause of the problem through the log of the problem detected during the reproduction test.

In other words, the conventional digital broadcast receiver must reproduce the same problem at the time of re-inspection so that the service personnel can solve the problem that the user has encountered during use. However, any system does not always produce the same problem. Therefore, the problem that occurs during the arbitrary operation of the digital broadcast receiver that receives the broadcast signal does not occur unless the same situation is reproduced. Therefore, it is difficult for the user to reproduce and solve the problem that occurred during use.

Also, when a set problem occurs, the user may not be immediately serviced with the problem that occurred in the set. For example, a problem arises in that a time taken by the distance between the user and the service center is taken, and a predetermined time elapses due to the service available time of the user and the service available time of the service center. After this time elapses, it is difficult to control the operation state of the set to the same state where the problem occurs.

Accordingly, an object of the present invention is to provide a log file management method and apparatus for a digital broadcast receiver capable of storing and managing a log containing a set problem as a file. .

The disk 41 or the like is further included. The hard disk 41 stores a log file containing a set problem in the present invention. At this time, the portion where the log file is stored needs to be preset to a predetermined portion of the hard disk 41.

In addition, the hard disk 41 stores a broadcast signal received through the tuner 30. For example, in the tuner 30, any of the digital satellite broadcasts received through the satellite broadcast antenna 200, desired by the user. Tunes into a broadcast channel.

The demux 31 demultiplexes the digital broadcast data stream received through the broadcast channel, and outputs the demux to audio, video, and data streams, respectively. The audio and video data streams are temporarily stored in the audio buffer 32 and the video buffer 33 and then read and signaled by the MPEG decoder 35 and output as audio and video signals. The broadcast signal output from the MPEG decoder 35 is encoded by the HDR system 40 and then recorded on the hard disk 41.

 The data stream is temporarily stored in the data buffer 34.
