The present invention relates to a digital recording device, in particular, to a digital recording device having a function of skipping advertisement between main broadcasts and recording only the main broadcast.

Representative products of the digital recording apparatus include a personal video recorder (PVR) set, which will be described below as a visual device.

PVR (Personal Video Recorder) is a new concept digital recorder that records and plays back information on the hard disk, unlike VCR (Video Cassette Recorder), which stores video signals on magnetic tape.

Hereinafter, a conventional visual device will be described with reference to FIGS. 1 and 2.

1 is a configuration diagram of a complex communication system in which a conventional FV device is installed.

Referring to FIG. 1, the FV device 102 performs a function of receiving and reproducing an airwave broadcast signal transmitted from a broadcasting station through the air antenna 104, or recording and replaying it later when requested by a user. Then, various kinds of point-to-point (PPP) information about a broadcast schedule is transmitted from a broadcasting station using a communication line through a telephone line.

In addition, the FV device 102 is connected to the cable converter 106 and receives various cable broadcast signals transmitted from the cable broadcasting station 108.

In this case, the type of cable converter 106 connected to the fib device 102 is preset in the setup mode of the fib device 102.

The cable converter 106 receives and processes the cable broadcast signal applied from the cable broadcasting station 108 and applies the A / V (Audio / Video) signal thus obtained to the fibrous device 102.

The video device 102 records broadcast information when a user requests through an A / V signal applied from the cable converter 106.

For example, when a user wants to record a video while watching a cable broadcast, the user presses the number and record button of a broadcast channel to record through an operation panel (not shown) provided in the TV device 102.

In addition, when scheduled recording of the broadcast to be watched is pressed through the operation panel of the fibrous device 102, the number and broadcast time of the broadcast channel to be recorded are pressed.

The AV device 102 transmits the broadcast recording request information input by the user to the IR transmitter 110 when a recording button is input or a scheduled broadcast time arrives.

The IR transmitter 110 transmits the broadcast recording request information set by the user as a remote controller to the cable converter 106.

The cable converter 106 is provided with a remote controller receiver (not shown) and outputs the cable broadcast signal of the channel received through the IR transmitter 110 to the FV device 102.

The FV device 102 records and reproduces, in real time, a cable broadcast signal of a selected channel through an A / V signal applied from the cable converter 106.

The video signal output from the video device 102 is input to the TV 100 so that the user can watch the image reproduced through the TV 100.

2 is a configuration diagram of a conventional FV device.

In order to broadly distinguish the functions of the FV device 102, the first function is to receive and reproduce an airwave broadcasting signal transmitted from a broadcasting station through the aerial antenna 104, or to record it later when requested by a user, The second function is to reproduce the A / V signal received through the cable converter 106 in the cable broadcasting station 108 as a second function.

The ROM 218 is a part in which a program to be driven is stored. As the program is executed, the operation of the device is performed.

The tuner 204 tunes a broadcast signal input through the antenna 104 and tunes to a desired specific frequency under the control of a system controller (not shown) to output the A / V signal.

The output A / V signal is input to the MPEG encoder 206 and the A / V converter 214. When the A / V signal is input to the MPEG encoder 206, the output A / V signal is a path for playback after recording. If directly inputted to 214, it is a path for direct reproduction.

As a component for playback after recording, the MPEG encoder 206 has an analog digital converter (ADC) to receive an input analog signal, digitizes it in real time, codes the compressed MPEG data, and converts the MPEG data into a HDD (Hard disk). drive 208).

In addition, the MPEG decoder 210 receives MPEG data stored in the HDD 208 and decodes the signal to generate an image signal.

That is, the MPEG decoder 210 incorporates a digital analog converter (DAC) to convert digital data stored in the HDD 208 into an analog signal. The analog signal converted by the MPEG decoder 210 is output to the A / V converter 214.

On the other hand, the video processor 212 configures a screen other than a broadcast screen such as a reservation recording function and outputs it to the A / V switching unit 214.

In addition, the video processor 212 has a picture-in-picture (PIP) function to output two screens simultaneously on one screen of a TV, or has an alpha-blending function to transmit a translucent image together with the image. Subtitles may be output on the screen of the TV 100.

At this time, the A / V switching unit 214 synthesizes an analog signal from the MPEG decoder 210 and a screen other than the broadcast screen from the video processor 212 and outputs it to the input terminal of the TV 100.

The FV device 102 generally includes a function of displaying broadcast programming information to a user in order to provide a recording function. The modem 222 is connected to a connection line via a telephone line and broadcast programming information necessary for scheduled recording from a broadcasting station is provided. It serves to receive the transmission.

The transmitted broadcast program information is temporarily stored in the RAM 220 and then outputs the stored broadcast information to the video processor 212 under the control of the CPU 216.

The RAM 220 also functions as a temporary storage location for storing data necessary during program execution.

In the following, the components related to the second function of the FV device 102 for reproducing A / V signals received from the cable broadcasting station 108 via the cable converter 106 will be described.

The external device A / V signal input terminal 202 is a terminal for receiving an A / V signal from the cable converter 106. The external device A / V signal input terminal 202 receives an A / V signal applied from the cable converter 106. Is applied.

The A / V switching unit 214 selects an image input from the external device A / V signal input terminal 202 under the control of the CPU 216, and outputs the selected cable broadcast signal to the TV 100.

As described above, the A / V switching unit 214 is an A / V signal for direct reproduction applied from the tuner unit 204, a recorded analog broadcast signal applied from the MPEG decoder 210, and an external device A / V. One of the A / V signals applied from the cable converter 106 through the signal input terminal 202 is selectively processed.

That is, the A / V switching unit 214 selects one video signal from the three video signals input under the control of the CPU 216.

Finally, the external device control port 200 is a port connected to the IR transmitter 110, and transmits the recording request information set by the user to the IR transmitter 110 under the control of the CPU 216.

The conventional FV device having such a configuration and operation is inconvenient for the user to watch an unwanted advertisement when the user plays after the recording is completed.

In order to solve this inconvenience, it is necessary to filter the advertisement during recording according to the user's setting so that the user can record only the desired broadcast except the advertisement.

The present invention is to provide a function and convenience that can satisfy the user's needs when recording and playing only the broadcast desired by the user excluding the advertisement by filtering the advertisement transmitted during the broadcast according to the user's setting Has its purpose.

In addition, there is another purpose to effectively filter the advertisement when recording using a digital recording device in a broadcast environment for transmitting the advertisement between broadcasts.

According to a preferred aspect of the present invention in order to achieve the above object, the step of monitoring whether a commercial is received during recording;
