BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording method of a personal video recorder (PVR) system. In particular, the recording speed of a broadcast program stored in a hard disk drive (hereinafter referred to as an HDD), which is a storage medium, may be adjusted. The present invention relates to a recording method of a FV system capable of sufficiently securing the storage capacity of the system.

In general, unlike a VCR (Video Cartridge Recorder) that stores a video signal on a magnetic tape, a PVR system is a new concept of digital recording device that records and plays back information on an HDD. It is a next-generation recording device that can record a certain amount of broadcast programs depending on the capacity without a VCR through the HDD built into the set-top box or television body. However, compared to the VCR, the program is compressed and recorded on the HDD (MPEG2 compression algorithm, etc.) to be recorded and played back using a file playback method such as a computer, and the CPU (Central Process Unit), operating system and software related to playback The difference is that there is a large capacity HDD in addition to the memory chip. Up to 30 hours of program can be stored and many programs can be recorded at the same time. In addition, it is possible to schedule recording by receiving the latest broadcast schedule from time to time by being connected to a modem or a LAN, and various services may be provided through the Internet. In addition, selecting a channel automatically saves the currently broadcast signal on the HDD and plays it back simultaneously. Therefore, if you press the stop button and press the play button again, the stored broadcast signal is not only played again from the point where it was stopped, but also the current broadcast program can be viewed again or played in slow motion, and there is a function to find or edit the desired program part.

In addition, the FB system can schedule program viewing according to personal choices and tastes, giving viewers more control over television. That is, viewers can watch the broadcast program they want when they want to see it, regardless of the program schedules prepared by the broadcasters.

FIG. 1 is a configuration diagram briefly showing a FB system according to the related art. In the related art, the FB system includes a key input unit 10, a CPU 12, a first memory 14, a HDD 16, and a tuner ( 18), MPEG 20, second memory 22, audio decoder 24, video decoder 26, audio output unit 28, video output unit 30, and the like.

In the conventional FB system configured as described above, the recording speed of the broadcast program stored (recorded) in the HDD is set every time or set to a preset value. At this time, the preset recording speed value is set to any one of HQ, HSP, SP, LP, EP, and SLP.

However, in the conventional TV system, it is very cumbersome to set the recording speed every time the broadcast program is recorded, and when it is fixed at the high quality recording speed, the HDD storage capacity cannot be secured sufficiently and the recording speed of the low quality is low. In the case of fixing to, there was a problem in that even a broadcast program requiring high quality should be stored at low quality.

An object of the present invention is to adjust the recording speed of the broadcast program for each storage folder or channel in order to solve the problems of the prior art can be stored in the HDD to automatically save the broadcast program in the desired image quality and the storage capacity of the HDD It is to provide a recording method of a FV system that can adjust the recording speed to ensure sufficient.

In order to achieve the above object, the present invention provides a method of recording a broadcast program on a HDD of a FB system, comprising: receiving a channel or a storage folder of a broadcast program and respective recording speeds; Storing each recording speed; and, if a recording key of a broadcast program is input after setting, specifying a recording speed of a channel or a storage folder of the broadcast program among the stored recording speeds, and randomly matching the recording speed. Recording a broadcast program.

The CPU 102 controls overall operation of the FB system, controls tuning of a broadcast program channel, receives an Electronic Program Guide (EPG) packet from the tuner 108, and receives a first memory (EPG) packet. And the decoding of the broadcast program data (audio and video) and the storage and reproduction of the broadcast signal to the HDD 106. Here, the electronic program guide (EPG) packet information is information including a broadcast station name, program name, start / end time, etc. of a broadcast program for searching for and selecting a broadcast program.

The CPU 102 stores, in the first memory 104, recording speed information of a preset broadcast program for each channel or storage folder according to the present invention, and the recording speed stored in the first memory 104 during recording or scheduled recording. According to the information, the MPEG 110 adjusts and compresses the recording speed of the broadcast program to be recorded, and stores (records) the HDD 106.

The first memory 104 stores packet data of additional information (channel information, electronic program guide information, and the like), and stores software programs such as overall operations (recording, playback, guide output, etc.) of the FB system. In addition, the recording speed information of the preset broadcast program is stored for each channel or storage folder during recording (or scheduled recording).

The HDD 106 stores a broadcast program to be recorded.

The tuner 108 tunes any broadcast channel among a plurality of broadcast program channels received through an antenna (not shown), and additional information (channel information, electronic program guide information, etc.) packets inserted on the transport stream of the tuned channel. Extract the data, and transmit the extracted additional information packet data to the first memory 104 through signal processing such as conversion to an intermediate frequency, error correction, and the like to a broadcast program of a selected channel extracted from a transport stream. After the signal processing such as the conversion to the intermediate frequency and error correction is transmitted to the MPEG (110).

The MPEG 110 compresses the broadcast program of the selected channel of the tuner 108 to a compression standard such as MPEG2 and delivers it to the HDD 106 or the audio / video decoders 114 and 116, and temporarily compresses the broadcast program (audio, Video) is stored in the second memory 112. At this time, the broadcast program stored in the second memory 112 is temporarily stored for a predetermined time for the operation of the fibral system such as the previous video search, backward playback, slow playback.

In addition, the MPEG 110 adjusts and compresses the recording speed of the broadcast target broadcast program according to the recording speed information stored in the first memory 104 under the control of the CPU 102, and transmits the compressed data to the HDD 106.

The audio decoder 114 restores the audio data to the original signal before encoding among the broadcast programs compressed using the MPEG2 audio decoding technique in response to the control of the CPU 102, and restores the restored audio signal to the audio output unit 118. To pass.

In response to the control of the CPU 102, the video decoder 116 encodes video data in a compressed broadcast program using video decoding techniques such as variable length decoding, inverse discrete transform, dequantization, and motion compensation. Reconstructs the original signal of and transmits the reconstructed video signal to the video output unit 120.
