Description

  The present invention relates to an AV data transmission system that receives a broadcast signal of a TV program or a radio program and transmits the broadcast signal so as to be viewable at a viewing destination terminal.

  When a TV program or radio program cannot be viewed in real time due to going out or work, it is common to record or record the TV program or radio program and view it later. Conventionally, various techniques have been proposed in order to improve the convenience of program recording reservation.

  For example, Patent Document 1 discloses a technique for making a program recording reservation on a portable terminal. Specifically, in this technology, program information is extracted from broadcast information sent by digital broadcasting, and the extracted program information data is converted into data that can be viewed by a general-purpose browser. Data is received by a portable terminal incorporating a versatile browser, and a program reservation is made by this portable terminal. Then, the recording device receives the program reservation data and records the program.

  According to this technique, it becomes possible to make a program recording reservation even from a place where the user is away, and the convenience is improved. However, in order to view the recorded program, it is necessary to go to the place where the recording device is installed, and the desired program cannot be viewed at a desired time.

For example, a TV program or the like may not be able to obtain services or benefits unless it responds within a predetermined time after the program ends. In such a case, in the technique of Patent Document 1, the TV program is viewed by recording. Even if it can be done, there will be a situation in which the service or privilege cannot be obtained due to time out.

  The problem to be solved by the present invention is to provide an AV data transmission system for enabling a user to view a desired TV program or radio program at a desired time while away from home.

  The AV data transmission system according to the present invention includes a receiving means for receiving an analog or digital broadcast signal of a TV program or a radio program, and an AV data format for converting the received broadcast signal into AV data that can be viewed at a viewing destination terminal. A conversion unit; and a transmission unit that transmits the converted AV data converted by the AV data format conversion unit or the AV data before conversion.

  In other words, in the present invention, the received broadcast signal is converted into AV data that can be viewed on the viewing destination terminal by the AV data format conversion means, and the converted AV data is transmitted, so that the tuner function of the TV / radio can be achieved. TV programs and radio programs can be viewed at a desired time on a viewing terminal such as a portable terminal or a personal computer that is not present. When the broadcast signal is in digital format and the received AV data can be viewed as it is on the viewing destination terminal, the received AV data may be transmitted as it is without being converted by the AV data format conversion means.

  In the present invention, AV data format specifying means for specifying the converted AV data format according to the type of the viewing destination terminal is provided, and the broadcast signal is converted into AV data specified by the AV data format specifying means. Can be.

  In addition, there is provided a dividing means for dividing the AV data distributed by digital broadcasting or the AV data after conversion of the broadcast signal into a plurality of files so as to be less than or equal to the amount of data that can be viewed at a time at the viewing destination terminal. You can also send multiple files.

  In this case, recording time designating means for designating the recording time of AV data per file can be provided, and the AV data can be divided into a plurality of files according to the recording time designated by the recording time designating means.

  In the present invention, the transmission means can transmit the AV data directly to the viewing destination terminal and view it on the viewing destination terminal. However, if the viewing destination terminal does not have enough storage capacity to store all of the AV data for one program, it is transmitted to the viewing destination terminal via a server on the Internet. In this case, the transmission means transmits and uploads the AV data to a designated URL (a dedicated home page for the viewer) on the Internet. In order to display a file list of uploaded AV data, its own home page is automatically updated. Automatic homepage updates can be performed using currently commonly used technologies such as uploading homepage data from the host terminal, or setting up an automatic update program in the uploaded homepage data. it can. In addition, when updating homepage data, as will be described later, information of “character string composed of numbers, characters, symbols, etc.” necessary for permitting access to the homepage or downloading of AV data is included. Sent to an Internet server and registered.

  The URL of the home page for uploading AV data is a unique address, and when this URL is accessed, the access permission means is a character composed of a unique number, character, symbol, etc. of the viewing terminal. It is also possible to check the column (hereinafter simply referred to as “character string”) and permit access only when this matches the character string of the viewing destination terminal registered in advance on the Internet server.

  In addition, when the AV data is downloaded from the URL to the viewing destination terminal, the unique character string of the viewing destination terminal is confirmed, and this matches the character string of the viewing destination terminal registered in advance on the Internet server. The download may be permitted only in the case where it is done.

  According to the present invention, it is possible to view a desired TV program or radio program at a desired time on the go.

  In addition, by installing a host terminal overseas and checking overseas broadcasts, the media representatives can know overseas news faster than information posted on the Internet. Also, people working for securities companies, day traders, and people working for futures trading companies want to know the world news faster than anyone else. For these people, this system is very powerful.

  Embodiments of the present invention will be described below based on examples shown in the drawings.

  FIG. 1 is a system configuration diagram showing an embodiment of an AV data transmission system according to the present invention. In the figure, the host terminal 10 receives a broadcast signal by the receiving means 11, and converts the broadcast signal into AV data that can be viewed by the viewing destination terminal 30 by the AV data format conversion means 12. The converted AV data is designated by the AV data format designation means 13 according to the type of the viewing destination terminal 30. The converted AV data converted into AV data that can be viewed on the viewing destination terminal 30 is divided by the dividing unit 14 into a plurality of files so as to be less than or equal to the amount of data that can be viewed on the viewing destination terminal 30 at one time. Accumulated in the storage means 16. The recording time per file is specified by the recording time specifying means 15, and based on this, the dividing means 14 sequentially divides the converted AV data. Further, the start time and end time of data storage in the storage means 16, that is, the start time and end time of recording are designated by the recording start / end time designation means 18.

  The plurality of converted AV data files are uploaded to specific URLs on the Internet 20 by the transmission means 17. This URL is a unique URL address accessible from the viewing destination terminal 30. In order to download and view the AV data uploaded to this URL, the URL is first accessed from the viewing destination terminal 30. At this time, the access permission means 21 on the Internet 20 side confirms the unique character string of the accessed viewing destination terminal, and the character string is permitted from the URL to be browsed, that is, the Internet 20 Access is permitted only if the character string registered in advance in the server matches. When access is permitted, a download instruction is issued from the viewing destination terminal 30. At that time, the download permission means 22 on the Internet 20 side confirms a unique character string of the viewing destination terminal that has been instructed to download, and the character string is a character string necessary for browsing the URL, that is, the Internet 20. Download is permitted only when it matches the character string registered in the server. If the download is permitted, the AV data files are downloaded and viewed one by one.

  Hereinafter, each of the above-mentioned means will be specifically described.

  The receiving means 11 is incidental to the host terminal 10 and includes an antenna 11a and a tuner unit 11b in the illustrated example. When the tuner unit 11b (tuner function) is built in the host terminal 10 as in the illustrated example, the antenna 11a is connected to the tuner unit 11b of the host terminal 10. If the host terminal 10 does not have a built-in tuner function, a separate tuner is provided. If the program to be received is Internet content, the desired program is received by connecting the host terminal 10 to the Internet via a modem or a router. If it is desired to receive a broadcast signal of a radio program and the host terminal 10 does not have a tuner function, it can be received via the radio as a tuner unit.

  The AV data format conversion means 12 is incorporated in the host terminal 10 and converts the received broadcast signal into AV data that can be viewed on the viewing destination terminal 30 by converting the received broadcast signal in software, hardware, or software + hardware. . For example, the analog video signal (NTSC) is converted into MPEG2, the analog video signal (NTSC) is converted into MPEG4 (3GPP), and the digital video signal (MPEG2) is converted into AVI (Divx).

  The AV data format designation means 13 designates the converted AV data format to be converted by the AV data format conversion means 12. Specifically, in order to specify an AV data format that can be viewed on the viewing destination terminal 30, an AV data format format, a type (manufacturer) of the viewing destination terminal 30, and a model number are designated. The designation of each item by the AV data format designation means 13 can be easily performed on the display of the host terminal 10. FIG. 2 shows an example of the display screen. First, the AV data format format is designated on the first screen (a) (3GPP is designated in the embodiment), and the detailed setting button is clicked. The detail button is clicked here, even if it is the same AV data format, there are multiple types if it is finely classified, and there are terminals that can be viewed and some terminals that cannot be viewed. This is for further specifying a possible AV data format. For example, some manufacturers claim to be able to play back 3GPP format videos, while some can play 30 (30 frames) images per second, while others can only play 15 (15 frames) images. Even if the data format is the same, some data cannot be reproduced if the frame rate is different. Therefore, the AV data format is specified in more detail.

  Specifically, when the detailed setting is clicked on the first screen (a), the second screen (b) appears. On the second screen (b), the type (manufacturer) of the viewing destination terminal is designated (in the embodiment, Docomo is designated), and when the detailed setting button is clicked, the third screen (c) appears. In the third screen (c), the model of the viewing destination terminal is designated (P900 is designated in the embodiment). By specifying these items, an AV data format that can be viewed at the viewing destination terminal is selected and specified, and the AV data is converted into the AV data specified by the AV data format conversion means 12 described above. The order in which the first to third screens (a) to (c) in FIG. 2 appear may be arbitrary.

  In the embodiment, the AV data format specifying means 13 is incorporated in the host terminal 10 and the AV data format is specified by operating the host terminal 10. However, the AV data format is specified by operating the viewing destination terminal 30. You may do it. In this case, the viewing destination terminal 30 accesses its own home page (a specific URL described later) on the Internet 20, and the AV data format is designated on the screen in the same manner as in FIG. Then, the designated contents are transmitted to the AV data format conversion means 12 in the host terminal 10 via the Internet 20 and reflected.

  Further, the format can be specified by transmitting “use terminal model number” and “designated format” as shown in FIG. 3 from the viewing destination terminal 30 to the host terminal 10 by mail.

  The dividing unit 14 is incorporated in the host terminal 10 and divides the converted AV data converted by the AV data format converting unit 12 into a plurality of files in software, hardware, or software + hardware. . The dividing unit 14 divides the converted AV data into a plurality of files according to the recording time designated by the recording time designating unit 15. For example, when dividing every minute, the dividing AV data The file is sequentially divided as one file every minute from the start of reception, and the file is stored in the storage means 16. In the embodiment, the converted AV data is divided. However, the AV data before conversion (AV data distributed by digital broadcasting, etc.) is divided and stored after being converted by the AV data format conversion means 12. You may make it accumulate | store in the means 16. FIG.

  The recording time designating unit 16 designates the recording time for each file so that the capacity of one file generated by the dividing unit 14 is less than or equal to the amount of data that can be viewed at the viewing destination terminal 30 at one time. The recording time designation by the recording time designation means 16 can be easily performed on the display of the host terminal 10. FIG. 4 shows an example of the display screen. By inputting the recording time on this screen and clicking OK, the recording time is designated.

  In the embodiment, the recording time specifying means 13 is incorporated in the host terminal 10 and the recording time is specified by operating the host terminal 10. However, the recording time may be specified by operating the viewing destination terminal 30. In this case, the viewing destination terminal 30 accesses a personal homepage on the Internet 20, and the recording time is designated on the screen in the same manner as in FIG. Then, the designated content is transmitted to the dividing means 14 in the host terminal 10 via the Internet 20 to be reflected.

  Also, for example, a mail as shown in FIG. 5 can be transmitted from the viewing destination terminal 30 to the host terminal 10 to specify the recording time. In this case, a mail address is registered in advance on the host terminal 10 side, and only mail sent from the registered address is checked.

  The recording start / end time designation means 18 designates the start time and end time of data storage in the storage means 16, that is, the recording start time and end time. This is the same as that applied in the current video tape recorder, by directly inputting the start time and end time of recording by the operation on the host terminal 10 side, or by inputting G code or EPG (electronic program code). It can be realized by doing.

  Also, the start time and end time of recording can be specified from the viewing destination terminal 30. FIG. 6 shows an example of the display screen. On this screen, the recording start time and end time are directly input or a G code is input and transmitted to the host terminal 10 via the Internet 20. Further, for example, a mail as shown in FIG. 7 can be transmitted from the viewing destination terminal 30 to the host terminal 10 to specify the recording start time and end time, or the G code.

  The storage means 16 is for accumulating each file of the converted AV data, and is constituted by a normal hard disk, memory, or the like.

  The transmission means 17 uploads each file of the converted AV data stored in the storage means 16 to a specific URL on the Internet 20, and can be configured by normal automatic transfer software or the like.

  The access permission means 21 is provided on the server side of the Internet 20 for permitting only a specific person access to a URL (homepage) to which each file of AV data is uploaded. The access permission means 21 may be a method in which an ID and a password are input and the access is permitted only when they coincide with those registered, as is normally done. A method using a unique character string of the terminal is adopted.

  The premise is that the URL is a unique address prepared for each viewing destination terminal 30. The unique character string of the viewing destination terminal 30 includes a mobile phone number for a mobile phone, an OS registration number and a product number for a personal computer, but is not limited thereto. It may be a character string composed of unique unique numbers, characters, symbols, and the like. The unique character string for each viewing destination terminal is registered from the host terminal 10 to the server side of the Internet 20. When the URL is accessed, the Internet server checks the unique character string of the viewing terminal, and the character string permits the URL to be browsed, that is, the Internet 20 server. Access is permitted only when it matches a character string registered in advance.

  Specifically, when there is an access from the viewing destination terminal 30 to a server in which homepage data is stored, the server has the above-mentioned characters of the viewing destination terminal 30 before sending the homepage data to the viewing destination terminal 30. Go to read the column. Then, the home page data is transmitted to the viewing destination terminal 30 only when the character string is confirmed and matches the character string registered in advance in the server.

  As described above, this access permission means designates the AV data format that can be played back on the viewing destination terminal, the recording time per divided file, the start time and end time of recording, and the like from the viewing destination terminal 30. When accessing the above URL, the unique character string of the viewing destination terminal is also confirmed, and the character string permitted from the homepage to be browsed, that is, the server of the Internet 20 is previously stored. Allow access only when it matches the registered character string, or allow access only when it matches the registered character string after confirming the ID and password. Let it be allowed.

  Finally, the download permission means 22 is for permitting only a specific person to download each file of AV data, and is provided on the server side of the Internet 20. This download permission means 22 also uses a unique character string of the viewing destination terminal, confirms the unique character string of the viewing destination terminal that has been instructed to download, and tries to view the character string. Download is permitted only when it matches a character string permitted from the homepage to be registered, that is, a character string registered in advance in the server of the Internet 20. If the download is permitted, the AV data files are downloaded and viewed one by one.

  In the above embodiment, the dividing means 14 divides the AV data into a plurality of files so as to be less than the data amount that can be viewed at the viewing destination terminal 30 at a time. However, the storage capacity of the viewing destination terminal 30 is large. If it is not necessary to divide, the dividing means and the recording time specifying means attached thereto may be omitted. Further, each file of AV data is uploaded to a specific URL on the Internet by the transmission means 17 and then downloaded to the viewing destination terminal 30 one by one. However, the storage capacity of the viewing destination terminal 30 is large. When all the AV data for the program can be received and reproduced at a time, the transmission means 17 may directly transmit it to the viewing destination terminal 30 by mail.

  This system is very useful for media, stocks, futures and day traders. It is possible to get information faster than the Internet by setting up a host terminal overseas and checking overseas broadcasts, and to anticipate ahead of anyone ahead of anyone's attention. Because it can.

  Another great merit is that people working overseas can watch programs broadcast in their home countries.

  In addition, services and benefits may not be obtained for TV programs or the like unless they respond within a predetermined time during or after the program. In such a case, it is possible to receive services such as TV programs just by having the viewing destination terminal at hand and being in a communicable area.
