  One improvement in this regard is that if the audio multiplex signal mode is “stereo”, it is a music program, if it is “duplex”, it is a movie program, and if it is “monaural”, it is a news program. There is a method to switch. However, in this case, the classification is large. For example, when viewing a variety program broadcast on “stereo”, the low and high sounds are emphasized, and it may be difficult to hear human voice.

  On the other hand, electronic program information (EPG) is operated from satellite broadcasting to terrestrial broadcasting, and broadcast program contents are classified by “program genre”. For example, broadcast programs are classified into genres in detail, such as “movie”, “music”, “variety”, “news”, and “sports”.

  The present invention provides a recording / reproducing apparatus that makes it possible to comfortably view a broadcast program by using this electronic program guide, eliminating the difficulty of listening to audio of a television broadcast and recorded / reproduced audio on an audio apparatus. The purpose is to do.

  The recording / reproducing apparatus of the present invention uses the “program genre” information included in the EPG to cope with the above-described object, and uses the audio EQ according to the “program genre” information when watching or recording / reproducing a television broadcast program. Is the main feature.

  Specifically, a television broadcast receiving unit that receives a television broadcast signal and electronic program guide data and outputs a video / audio signal and program genre information, a video / audio signal and program genre information output from the television broadcast reception unit, a web, etc. A signal processing unit that outputs a program genre signal acquired from an external network of the computer and records and reproduces the signal in a recording media unit, an audio equalizer and an amplification unit having an equalizer capable of switching frequency characteristics of reproduced audio, and the television broadcast reception , A signal processing unit, a sound equalizer and a microcomputer for controlling the amplification unit, and the program genre information is extracted from the electronic program guide or the recording medium when receiving or recording / reproducing a television broadcast, and optimized for each program genre. Equalizer for the equalizer and amplifying unit so as to obtain sound frequency characteristics It is characterized in switching the The characteristics automatically.

  The recording / reproducing apparatus of the present invention acquires a “program genre” of a currently received program from EPG data superimposed on a broadcast wave or EPG data on the web when receiving a television broadcast, and an audio equalizer corresponding to the “program genre”. Automatically select and view comfortably, and by writing the “program genre” to the recording media in the same way as the program name at the time of recording, the “program genre” is read out during playback, and an audio equalizer corresponding to the “program genre” There is an advantage that can be selected automatically and can be viewed comfortably.

  Hereinafter, a recording / reproducing apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a recording / reproducing apparatus according to an embodiment of the present invention. Here, an example of an audio apparatus equipped with a DVD recorder is shown. 2 is a frequency characteristic diagram showing an example of the frequency characteristic of the audio equalizer, and FIG. 3 is a comparison diagram showing an example of the audio equalizer characteristic corresponding to the program genre.

  In FIG. 1, a television broadcast receiving unit 1 receives a television broadcast signal including program genre information A, and outputs a video / audio signal and program genre information A to a signal processing unit 3.

  A microcomputer (hereinafter referred to as a microcomputer) 2 performs reception control of the television receiver 1 and controls the audio equalizer and amplifier 5 in accordance with program genre information from the signal processor 3. The microcomputer 2 originally controls the respective parts of the recording / reproducing apparatus in addition to the reception of the television broadcast, and the function of the present invention is added by adding a part of the program.

  The signal processing unit 3 receives the AV signal and the program genre information A obtained from the television broadcast receiving unit 1, receives the genre information B from the web or the like, and sends the AV signal and the program genre information A or B to the recording medium 4. Let me record.

  The recording medium unit 4 records and reproduces the AV signal and the program genre information A or B on a recording medium such as a hard disk, DVD-RAM, or DVD-R.

  The audio equalizer and amplifying unit 5 is based on the control of the microcomputer 2 for the audio signal among the AV signals output from the signal processing unit 3, input from the television broadcast receiving unit, or reproduced from the recording media unit 4. The equalizer is switched corresponding to the program genre information, amplified and reproduced from the speaker 6.

  Program genre information is included in electronic program information (EPG). When receiving a television broadcast, there are a case where a program is selected from an EPG and a case where a program is directly selected by a remote controller or a main body operation unit. In the former case, the microcomputer 2 extracts “program genre” information from the EPG, refers to the comparison table in FIG. 3, and automatically switches between the audio equalizer and the audio equalizer of the amplifying unit 5 according to the program genre information. In the latter case, the microcomputer 2 retrieves the “program genre” information by searching for an EPG from a television broadcast or the web, and automatically switches between the sound equalizer and the sound equalizer of the amplifying unit 5.

  When recording a television broadcast, there are a case where a recording reservation is made from the EPG and a case where a recording reservation is set directly by a remote control or the like. In the former case, the microcomputer 2 extracts “program genre” information from the EPG and records it on the recording medium simultaneously with the “program title”. In the latter case, the microcomputer 2 retrieves the “program genre” information by searching for an EPG from a television broadcast or the web, and records it on a recording medium. The program genre information may be recorded in a specific area provided on the recording medium, and the method is not limited.

  At the time of reproduction from the recording medium, the microcomputer 2 determines the “program genre” information recorded on the recording medium, and automatically switches the sound equalizer according to FIG.

  EQ1 (heavy) is a characteristic that enhances low and high frequencies, and the background assigned to “program genres” such as movies is when many sound effects are recorded in low and high frequencies in movies and the like. This is because the sound reproduction is powerful by emphasizing the low and high frequencies.

  EQ2 (flat) is a flat characteristic from low to high, and the background assigned to “program genre” such as music is flat because the audio circuit is optimally designed for playback of music CDs and the like. This is to achieve a high frequency quality and to enjoy music programs with high sound quality.

  EQ3 (soft) is a characteristic in which the low frequency band is enhanced, and the background assigned to the “program genre” such as variety is to reduce the stimulation sound and to concentrate on the image.

  EQ4 (vocal) is a characteristic in which the low range is attenuated and the mid range is enhanced, and the background assigned to “program genre” such as news is to emphasize the audio band and make it easy to hear the announcement.

  EQ5 (clear) is a characteristic that attenuates the low range and enhances the high range, and the background that is assigned to the “program genre” of sports is to effectively give a live feeling in the field by emphasizing the high range. It is.

  As described above, according to this embodiment, the microcomputer 2 determines the “program genre” information at the time of receiving the television broadcast and recording / playback, and automatically selects the optimum audio equalizer to comfortably view the device. This was realized by improving the program.

  As described above, the recording / reproducing apparatus of the present invention acquires the “program genre” of the currently received program from the EPG data superimposed on the broadcast wave or the EPG data on the web when receiving the television broadcast, and sets it as the “program genre”. A compatible audio equalizer is automatically selected for comfortable viewing, and the “program genre” is written to the recording media in the same way as the program name during recording, so that the “program genre” is read out during playback. Can be applied to recording and playback devices that can receive, record and play back all video and audio services that can search for “program genre” information using EPG.
