Hereinafter, the television program video server device 10 and the client device 30 will be described in detail.
[Description of Television Program Video Server Device]
The television program video server apparatus 10 according to the embodiment of the present invention is a computer that executes processing in response to a request from the client apparatus 30. The television program video server apparatus 10 is characterized in that a desired content in a recorded program is searched by an acoustic waveform.

  FIG. 2 is a functional block diagram of the television program video server apparatus 10 according to the embodiment of the present invention. As shown in this figure, the television program video server apparatus 10 includes a communication unit 11, a recording unit 12, a waveform generation unit 13, an audio file creation unit 14, a search unit 15, and an optimization information determination unit 16. It is equipped with.

  The communication unit 11 transmits / receives data to / from the client device 30 by TCP / IP connection. The communication means 11 is realized by a modem or a router attached to the computer.

The recording unit 12 records broadcast program data of a plurality of channels continuously for each channel for a certain period. The recording means 12 can be realized by, for example, a video recorder or a personal computer that can continuously record multiple channels simultaneously. The personal computer and video recorder connected to the TV antenna are hard disk type video recorders equipped with multiple tuners corresponding to terrestrial analog, digital terrestrial, and satellite broadcasting. Program information is acquired from the (electronic program guide), information such as program name, genre, and performer is added to the recorded program and recorded on a hard disk drive (hereinafter referred to as a first database) 12A as a recording medium.
The program information recorded by the recording means 12 is a movie file (Movie File) in which moving images and sounds are recorded. The format of the movie file is, for example, AVI (Audio Video Interleave), MPEG (Moving Picture Expert Group). ), WMV (Windows (registered trademark) Media Video).

  In order to provide means for recording terrestrial digital broadcasts, a tuner is mounted for each digital broadcast channel, and multiple channels are continuously recorded at the same time, as with analog broadcast recording means. In the case of analog broadcasting, EPG is received via the Internet, program information is acquired from the received EPG, and program information is added to the recorded program and recorded. In the case of terrestrial digital broadcasting or satellite digital method, EPG is received simultaneously with digital broadcasting.

  The waveform generation unit 13 generates a speech waveform corresponding to a keyword based on a text file received from the client device 30 via the communication unit 11, that is, a keyword including characters and numbers. Since characters such as common nouns and proper nouns have a unique acoustic waveform when converted to speech, in this embodiment, a database in which the character and the acoustic waveform when the characters are converted into speech are linked in advance. (Hereinafter referred to as the second database) 13A, that is, recorded in the dictionary means, and the received character is converted into a speech waveform. The waveform converted in this way is handled as one image and processed thereafter. Specifically, as shown in FIG. 3 (A), when the user selects the character “Okinawa” as a keyword, for example, the waveform generation means 13 searches the second database 13A, as shown in FIG. 3 (B). The image file 13C representing the acoustic waveform 13B corresponding to the Japanese character “Okinawa” is extracted.

The audio file creating unit 14 creates audio information from the broadcast program data recorded by the recording unit 12.
Since broadcast program data is recorded in AVI format and has a large amount of data, it is time consuming and inefficient to process broadcast program data information in AVI format as it is. For this reason, the audio file creation means 14 includes a WAV data creation means 14A, and the WAV data creation means 14A extracts a sound file from broadcast program data information in the AVI format. Specifically, only the data having the WAV format, that is, the WAV extension is extracted.

Furthermore, since the WAV format sound file has header information explaining the data, it cannot be specified how many minutes and seconds the searched video portion is after the start time. For this reason, the audio file creation means 14 includes PCM data creation means 14B. The PCM data creation means 14B removes header information describing the data from the sound file in the WAV format, and PCM (Pulse Code Modulation: Pulse Code). Conversion to PCM data using Modulation).
As described above, the audio file creation unit 14 includes the “WAV data creation unit 14A” and the “PCM data creation unit 14B”, and first creates the WAV data and then creates the PCM data from the created WAV data.

  Note that the WAV data creation means 14A performs encoding, ie, compression, by deleting the moving image from the broadcast program data information in the AVI format, instead of extracting the sound file from the program information in the AVI format. It may be configured to create a file.

The created PCM data is stored in association with the time when the original program information was broadcast. That is, the broadcast start time of the original program information is associated with the start playback start time of the PCM data. For example, if the broadcast disclosure time is 7:00 pm, the sound at 35 minutes after playback in the PCM data is Corresponds to the audio in the program at 7:35 pm.
In this way, the PCM data is recorded on the hard disk (referred to as the third database) 14C in association with the broadcast time of the original program information.

  The search means 15 searches the third database 14 </ b> C using the speech waveform generated by the waveform generation means 13. Specifically, the search means 15 uses the image file 13C (see FIG. 3B) showing the acoustic waveform generated by the waveform generation means 13, for example, the acoustic waveform 13B, as shown in FIG. The waveform 13D image indicated by the PCM data and the image of the acoustic waveform 13B are collated to determine whether a waveform that matches the image of the acoustic waveform 13B exists in the PCM data, and time information t of the matching portion (region) is extracted. .

The time extracted by the search means 15 is output as the following information.
When the time extracted by the search means 15 is t (year, month, hour, minute, second), the time from the time t to the time (t + α) after a predetermined time α [second] is extracted from the search result. To do. This search result is composed of numbers and hyphens. For example, if α is set to 5 minutes and 10:06 June 30, 2007, 8:20:15 is extracted by the search means, June 30, 2007, 8:20:15 to June 2007 As information on 10th channel on 30th, 8:25:15, a result of “20070709063082015051-120090600300825155051” is created.
For example, the search result is created as a file in HTML (Hyper Text Markup Language) format in the television program video server apparatus 10.
The search result created in this way is transmitted to the client device 30 via the communication unit 11.

Further, the optimization information discriminating means 16 discriminates a preferable resolution when the user saves the content specified by the above-mentioned time t on a recording medium such as a DVD or a CD, and informs the user.
When the corresponding acoustic waveform is found in the audio file by the search by the search means 15, the genre information is informed by the EPG in the movie file which is the original data of the audio file. Based on this genre information, the optimization information discriminating means 16 of this embodiment determines the genre to which the content specified by the time t extracted by the searching means 15 belongs and discriminates the resolution at the time of saving.
Specifically, as shown in FIG. 4, the resolution includes a high resolution for a high-definition level, a medium resolution for a DVD level, and a low resolution, and a genre corresponding to each resolution is not set by the user independently. In some cases, it is assigned in advance. The optimization information discriminating means 16 holds a table as shown in FIG. 4 and specifies the resolution from the genre of the content specified by the time t extracted by the searching means 15. The identified resolution is transmitted to the client device 30 as an identification code (1-3).
