Description

  The present invention relates to a communication device with a television reception function and a broadcast recording apparatus.

  2. Description of the Related Art Conventionally, a mobile phone with a TV reception function has been provided, and such a mobile phone receives a terrestrial analog broadcast by a small built-in tuner and displays a received image on a liquid crystal display panel. Similarly, terrestrial digital broadcasting can be received by a small device. However, mobile devices such as mobile phones are small in screen size and lack of video definition. Furthermore, because the radio wave condition deteriorates, broadcasts cannot be viewed. There is a demand to save the current program so that it can be viewed many times later.

  The recording reservation function from the outside is realized as a network recording reservation function in a video recorder, and it is possible to make a recording reservation by itself without requiring a family member or an acquaintance at home to record the program. In order to realize this network recording reservation function, it is necessary to transmit information (broadcast channel, start time, end time, etc.) of a program to be recorded on a home video recorder from a device outside the home. In the IPv4 (internet protocol version 4) environment, which is currently the mainstream, fixed global addresses are rarely assigned to devices in the home, and a firewall is installed at the entrance of the Internet in consideration of network security. Often prevent unauthorized access to devices in the home. For this reason, in order to realize the network recording reservation function, a special mechanism for transmitting program information from the outside to the home video recorder is required (see Patent Document 1, Patent Document 2, and Patent Document 3). This mechanism is classified into three main categories, “mail method”, “data registration method” and “real-time method”. Each method will be described below.

  First, the “mail system” will be described. A user sends a fixed format mail in which recording command information is written using a PC (personal computer) or a mobile phone to a mail server registered in advance in the video recorder. The video recorder reads the mail of the account of the video server registered at regular time intervals, and if there is a standard mail in the read mail, the recording command information is automatically extracted and the recording reservation process I do. In addition to using e-mail that does not require real-time information transmission methods, it is not possible to record e-mail from a video recorder in real time because e-mail cannot be delivered immediately to the mail server.

  Next, the “data registration method” will be described. A user accesses a Web server installed on the Internet from a remote location using a PC or a mobile phone, and selects a program to be reserved from an EPG (electronic program guide) written on the Web page. Similarly, the Web server transfers the program information selected by the user to a data server on the Internet. The video recorder reads the data registered in the data server at regular time intervals in the same way as the mail method, reads the recording command information if it exists in the data server, and automatically extracts the recording command contents. To perform recording reservation processing. Since the exchange of information between the Web server and the data server and between the data server and the video recorder is performed by an arbitrary protocol such as POP (mail reception protocol) or HTTP (Web protocol), the data server functions as a mail server or a Web server at the same time. have. This method, like the mail method, cannot be recorded in real time because the data cannot be read out immediately after the data reaches the data server. Although it is similar to the mail system, here, the user is distinguished depending on whether the user sends an email from outside or selects a program from a Web page.

Finally, the “real time method” will be described. This method can transmit information to the video recorder in real time, unlike the two methods described above. There are several implementation methods, but an example is shown below. This creates an environment in which a video recorder in the home can be accessed directly from the outside using VPN (virtual private network) and dynamic DNS (domain name system), and the web server in the video recorder and the PC or mobile phone in the outside are directly connected. Exchange data. Since this method is characterized by real-time characteristics, users on the go often exchange information using HTTP using a Web browser.

  However, the above-described conventional technique is merely a technique for realizing recording reservation from an external video recorder from a mobile phone or the like. Therefore, it is not realized that an external video recorder simultaneously receives and records the same broadcast (program) as the broadcast (program) being viewed on the mobile phone.

  In view of the above circumstances, an object of the present invention is to realize that an external video recorder simultaneously receives and records the same broadcast (program) as the broadcast (program) being viewed on a mobile phone or the like. To do. Here, it can be considered that zapping is performed when a program being viewed on a mobile phone or the like is commercialized, and if the recording target broadcast by an external video recorder is switched by such zapping, the recorded video is It becomes choppy. In view of this, it is also an object of the present invention to prevent the recorded video from an external video recorder from being interrupted due to zapping of broadcast viewing on a mobile phone or the like.

  In order to solve the above problems, a communication device with a television reception function according to the present invention is a communication device with a television reception function having a function of receiving a television broadcast and a communication function of information.

Also good. This configuration can be used when the broadcast receiving and recording apparatus includes a plurality of tuners and can record programs received by the tuners.

  Further, in the mobile communication device with a television reception function having these configurations, the notification means includes means for storing address information of a plurality of external broadcast reception recording apparatuses and attributes of each broadcast reception recording apparatus, It is also possible to select a broadcast receiving / recording device to which a recording command or a channel change command is to be given based on the attributes of the program being broadcast and the attributes of each broadcast receiving / recording device. With such a configuration, for example, a high-vision program can be recorded by a high-definition broadcast receiving and recording device, and a non-high-definition program can be recorded by a non-high-definition broadcast receiving and recording device.

  Moreover, in the mobile communication device with a TV reception function having such a configuration, the communication device has a function of receiving 1 seg broadcasting in terrestrial digital broadcasting as a TV receiving function, and the notification means corresponds to the received 1 seg broadcasting. Information for receiving the 12-segment broadcast or the primary channel may be transmitted as information indicating the channel.

  Further, in the mobile communication device with a television reception function configured as described above, the notifying unit is provided in the broadcast receiving and recording device based on an end time input by the user at the start of watching TV or a program end time obtained based on program information. A recording end instruction or a recording end time may be notified. Alternatively, the notifying means may notify the broadcast receiving / recording apparatus of a recording end instruction when the television viewing ends.

  Also, the broadcast receiving and recording apparatus of the present invention receives information indicating a viewing channel and information indicating a recording command, performs channel selection and recording processing of the viewing channel, and indicates a channel after change. It is characterized by comprising recording means for selecting a channel after the change and recording processing when information is received.

  With the above configuration, it is possible to simultaneously receive and record the same broadcast (program) as the broadcast (program) viewed on the communication device with the television reception function by the external video recorder.

May determine whether to perform the recording of the channel after the change based on the condition. By having the determination table, it is possible to prevent the video recorded by an external video recorder from being interrupted due to broadcast viewing zapping in a mobile communication device with a television reception function.

  The condition in the determination table may be a channel maintenance time after the change. The changed channel maintenance time in the determination table may vary depending on the viewing duration of the channel that was being viewed before the change.

  The broadcast receiving and recording apparatus having such a configuration includes a determination table that defines a condition that specifies whether to start recording immediately after a recording instruction is received or after a predetermined time, and the recording unit immediately includes the condition based on the condition. Alternatively, recording may be executed after a predetermined time.

  According to the present invention, it is possible to easily perform the process of recording the program on the home video recorder while watching the television program. In addition, there are various effects such as the fact that recorded video by an external video recorder can be prevented from being interrupted by zapping of broadcast viewing in a mobile communication device with a television receiving function.

  A portable communication device with a television reception function and a broadcast reception recording apparatus according to an embodiment of the present invention will be described below with reference to FIGS. In the example shown below, a process of recording a program on a home broadcast reception recording device (hereinafter referred to as a video recorder) while watching the television program on a mobile communication device with a television reception function (hereinafter simply referred to as a mobile phone). Although the case where the network recording command technology described in Patent Document 1 (Japanese Patent Laid-Open No. 2006-20248) described above is used is exemplified, the network recording command technology itself may use another technology. Is possible.

  FIG. 1 is a block diagram showing a mobile phone 10 of this embodiment. FIG. 2 is an explanatory diagram showing a schematic configuration of the broadcast recording system. This system includes a mobile phone 10, a server 30, the Internet 40, and a video recorder 50 installed in the home. The video recorder 50 can be realized by an existing video recorder equipped with a network recording function. Also, the existing server 30 that realizes the network recording function can be used.

  In the block diagram of FIG. 1, a tuner 11 receives terrestrial analog broadcasts and terrestrial digital television broadcast waves based on channel selection information by a user's channel selection operation, and performs processing such as demodulation and decoding to generate a video signal. . The display unit 12 is composed of, for example, a liquid crystal panel, and displays video based on the video signal of the terrestrial digital television broadcast. In addition, the display unit 12 displays an image generated by the Web client unit 17 and an OSD (on-screen display) circuit (not shown). Display the generated image. The communication control unit 13 performs communication processing when the Web client unit 17 operates, communication processing when the mail transmission / reception unit 18 operates, and the like. In addition to performing various processes in the mobile phone 10, the CPU 14 also performs processes related to character string generation for recording commands to be described later. A memory (ROM, RAM, EEPROM, flash memory, etc.) 15 stores various programs and determination rules relating to recording commands. This determination rule will be described later. The operation unit 16 is provided with a numeric keypad, a cross key (arrow key), and various function keys. In this embodiment, a TV viewing button (not shown) is provided on the operation unit 16. Note that the TV viewing button may be a dedicated button, or may be a method that uses a button that corresponds to the notation of “TV viewing” in the display on the screen, or a button displayed on the screen. (Touch panel method) may be used.

  The Web client unit 17 transmits a notation (URL) that specifies how to reach a resource existing on the Internet, interprets an HTML file transmitted from the resource side, and generates display image data. I do. The mail transmitting / receiving unit 18 performs a process of receiving a mail from a mail server on the Internet or transmitting a mail text to the mail server. The recording instruction processing unit 19 performs a recording instruction process which will be described later. In addition to storing various data in the database 20, the broadcast station ID for knowing the broadcast station ID from the information (email address, IP address, host name, etc.) specifying the video recorder 50 set by the user and the channel number Information necessary for network recording, such as correspondence tables and secret words, is registered. In digital terrestrial broadcasting, information such as a network ID can be acquired from PSI / SI of a received broadcast wave, and a channel can be specified using the network ID or the like without using the broadcast station ID correspondence table. . The telephone unit 21 performs processing for a telephone which is an original function.

In this embodiment, information exchange to the video recorder 50 is performed on the Web in a real-time manner. As a recording command transmission character string, for example, a URL character string of the following format is created by the recording instruction processing unit 19 and the Web It is given to the client unit 17.
http: // [server name] / [server CGI program path] # id = [broadcast station ID] & word = [aikoba]

  Basically, when detecting the depression of the TV viewing button, the CPU 14 starts broadcast reception processing and performs command processing for causing the video recorder 50 to record the currently received broadcast (program). Specifically, the CPU 14 gives the number of the channel currently being viewed to the recording instruction processing unit 19, and when the channel is changed by the user, in principle, the channel number after the change is recorded. Part 19 is given. When the channel number is given from the CPU 14, the recording instruction processing unit 19 creates the URL character string described above and gives it to the Web client unit 17. The Web client unit 17 performs transmission processing to the server 30 each time a new URL character string is created. The processing contents are basic contents, and the processing contents change according to the determination rule.

  A configuration example for recording in the video recorder 50 is shown in FIG. In this configuration diagram, the recording information receiving unit 51 and the CPU 54 realize the network recording function. The recording information receiving unit 51 functions as a POP (mail reception protocol) client or an HTTP (Web protocol) server. In this embodiment, the exchange of information from the data server to the video recorder is performed on the Web in real time, and the request for the URL in the above-described format is sent to the Web server in the video recorder 50 which is the recording information receiving unit 51. Sent.

  In this case, the recording information receiving unit 51 is a CGI (commom gateway interface) program in the server, and the CGI program extracts information after “#”. Although the above example shows the case of a GET (document acquisition) request, program information (channel selection information) can be similarly acquired using a CGI program in the case of a POST (data transmission to the server) request. .

  As described above, the recorded program information (recording command content) received by the recorded information receiving unit 51 is passed to the CPU 54. The CPU 54 determines the channel number by comparing the broadcast station ID with a broadcast station ID correspondence table (not shown), and provides channel selection information to the tuner of the recording unit 55 based on the determined channel number. The video and audio of the program (video / audio) received by the tuner is converted into video data and audio data by the recording unit 55 and recorded in the hard disk 52.

  Next, the determination rules stored in the memory 15 of the mobile phone 10 will be described. This determination rule is a determination criterion when a recording start instruction or a recorded program change instruction is transmitted to the video recorder 50 based on an operation performed on the mobile phone 10 side.

[Judgment rule]
(1) The current recording state in the video recorder 50 is maintained until a predetermined time has elapsed after the channel change. Specifically, the CPU 14 does not give the change channel number to the recording instruction processing unit 19 until a predetermined time has elapsed after the channel change. Therefore, the URL character string related to the changed channel is not created, and no new command is issued to the video recorder 50. Accordingly, the current channel recording process in the video recorder 50 is maintained.

(2) When a predetermined time elapses after the channel change, the video recorder 50 changes the reception channel, and performs recording of the channel after the change. Specifically, the CPU 14 gives the change channel number to the recording instruction processing unit 19 when a predetermined time has elapsed after the channel change. Therefore, a URL character string related to the changed channel is created and transmitted to the server 30 to give a new command to the video recorder 50. Therefore, the video recorder 50 performs the program recording process for the changed channel.

(3) The predetermined time after the channel change varies depending on the length of the program viewing time before the channel change. For example, if the program viewing time of the channel before change is less than 15 minutes, the predetermined time after the channel change is set to 15 seconds. If the program viewing time of the channel before change is 15 minutes or more, the predetermined time after the channel change is set to 15 seconds. 1 minute. Of course, the above-mentioned number of seconds is an example, and is not limited to this.

(4) A determination rule for starting recording may be set. For example, when TV viewing is started by specifying a program from the EPG, the video recorder 50 immediately performs recording. Specifically, the CPU 14 immediately gives the current channel number to the recording instruction processing unit 19. Therefore, a URL character string related to the channel at the start of TV viewing is created and transmitted to the server 30 to instruct the video recorder 50. On the other hand, when the TV viewing button is pressed, the video recorder 50 executes recording after 15 seconds have elapsed since the pressing. Specifically, the CPU 14 waits for 15 seconds after starting the TV viewing and gives the current channel number to the recording instruction processing unit 19. Of course, the above-mentioned number of seconds is an example, and is not limited to this.

  As described above, when a predetermined time elapses after the channel change, the change from (1) to (2) is performed in the determination rule. FIG. 4 is a flowchart showing the processing contents of the CPU 14. After starting TV viewing, user operations such as program switching are performed, and processing according to these operations and processing such as time measurement are performed in the CPU 14 (step S1). The CPU 14 determines whether or not the determination rule change condition is satisfied (step S2). When the change condition is satisfied, the determination rule is changed (step S3). Next, it is determined whether or not the determination rule adopted at the present time is satisfied (step S4). If not satisfied, the process proceeds to step S1, and if satisfied, processing such as a recording request is performed (step S5), and the process proceeds to step S1.

  Note that the correspondence between the broadcast station ID and the channel number in the broadcast station ID correspondence table is not limited to analog broadcast-analog broadcast or digital broadcast-digital broadcast. That is, even when the mobile phone 10 receives the analog NNN comprehensive broadcast, the video recorder 50 may associate the terrestrial digital NNN comprehensive broadcast. Of course, in digital broadcasting-digital broadcasting, it is conceivable that communication equipment with a television receiving function (for example, in-vehicle equipment) receives 12-segment broadcasting, and the video recorder 50 also receives 12-segment broadcasting. The one-segment broadcast may be received at 10, and the 12-segment broadcast or the primary channel may be associated with the one-segment broadcast in the video recorder 50. In the simulcast, since the program broadcast on the primary channel is also provided in the 1-segment broadcast, the video recorder 50 should select the primary channel.

When the viewing channel is changed to another channel, the CPU 14 and the reservation instruction processing unit 19 transmit information indicating the changed channel to the video recorder 50 (hereinafter sometimes referred to as A). Alternatively, when the viewing channel is changed to another channel, the information indicating the changed channel may be transmitted to another external video recorder (hereinafter sometimes referred to as B). In this case, for example,
(I) TV on mobile phone 10
(B) Reception of 8ch (c) Transmission of recording instruction to video recorder A (d) Change to 10ch (e) Judgment of whether or not the conditions of the judgment rule are satisfied (f) Video recording of 10ch when the condition is satisfied (B) 8ch recording in the video recorder A is processed according to the maintenance flow.

If the above-described determination rule is not provided, recording instructions are sequentially transmitted to a plurality of video recorders each time the channel is changed in the mobile phone 10. By providing the determination rule, it is possible to avoid useless use of the video recorder. More specifically, information related to a plurality of video recorders is registered in the mobile phone 10 in advance. For example, a URL character string in the following format is created by the recording instruction processing unit 19 and given to the Web client unit 17.
(1) About the first video recorder
http: // [server name (1)] / [CGI program path in the server] # id = [broadcasting station ID] & word = [aikoba]
(2) About the second video recorder
http: // [server name (2)] / [CGI program path in server] # id = [broadcasting station ID] & word = [aikoba]
It's like that.
When the mail method is used, it is only necessary that each video recorder has a mail address.

  The cellular phone 10 manages (stores) which video recorder is currently recording which channel. Note that, when the channel is further changed to 6ch in the process according to the flow described above, it may be determined whether or not the condition of the determination rule is satisfied, and when the condition is satisfied, 6ch recording may be instructed to the video recorder A. In this case, the video recorder is switched as A → B → A → B.

  The CPU 14 and the reservation instruction processing unit 19 are viewing instead of transmitting information indicating the changed channel to the video recorder 50 when the channel being viewed is changed to another channel. When the channel is changed to another channel, information indicating the changed channel and a new recording command for the changed channel may be transmitted to the video recorder 50. This configuration can be used when the video recorder 50 includes a plurality of tuners and can record each program received by each tuner. The process flow is the same as the process flow for the separate video recorders described above.

  The CPU 14 and the reservation instruction processing unit 19 use the memory 15 to store destination information of a plurality of external video recorders and attributes of each broadcast receiving / recording apparatus, and receive received program attributes and each video recorder's attributes. A video recorder to which a recording command or a channel change command is to be given may be selected based on the attribute. For example, it is assumed that there are a high-definition video recorder and a non-compatible video recorder. The attribute in this case is high-definition compatible or non-compatible. For example, when the mobile phone 10 receives 1-segment broadcasting and information indicating that high-definition broadcasting is being performed in 12 segments is obtained from, for example, program information, the CPU 14 and the reservation instruction processing unit 19 are compatible with high-definition television. A recording command or channel change command is given to the video recorder.

  Alternatively, it is assumed that the user uses one video recorder for sports program recording and another video recorder for other program recording. The attribute in this case is a program genre. For example, when the mobile phone 10 is receiving a baseball broadcast and the genre information that the received program is a sport is obtained from the program information, for example, the CPU 14 and the reservation instruction processing unit 19 may use a video recorder for recording a sports program. Is given a recording command or a channel change command.

  The CPU 14 and the reservation instruction processing unit 19 notify the video recorder 50 of the recording end instruction or the recording end time based on the end time input by the user at the start of TV viewing or the program end time obtained based on the program information. Also good. Alternatively, the CPU 14 and the reservation instruction processing unit 19 may notify the video recorder 50 of a recording end instruction when the television viewing ends. The latter notification method is effective when the video recorder 50 has a large capacity recording medium. Of course, the recording end instruction may be notified to the video recorder 50 when a button such as “stop recording” provided on the mobile phone 10 is operated.

  In the example described above, the mobile phone 10 includes the determination table, but the video recorder 50 may include the determination table. In this case, the mobile phone 10 gives the recording instruction processing unit 19 the number of the channel that is currently viewed after the change every time the channel is changed by the user without considering the passage of time. When a new channel number is given, the recording instruction processing unit 19 creates the URL character string described above and gives it to the Web client unit 17, and the Web client unit 17 sends to the server 30 each time a new URL character string is created. What is necessary is just to perform a transmission process.

  The contents of the determination table in the video recorder 50 are as follows.

[Judgment rule (for video recorder)]
(5) Even if a new URL character string is received, the video recorder 50 does not change the channel until a predetermined time has elapsed from that point. Specifically, when receiving the new URL character string, the recording information receiving unit 51 gives the broadcast station ID included in the URL character string to the CPU 54, and the CPU 54 determines a new channel number from the broadcast station ID. However, the CPU 54 does not immediately provide the recording unit 55 with channel selection information based on a new channel number. That is, even if the CPU 54 determines a new channel number, it does not give channel selection information to the recording unit 55 until a predetermined time has elapsed. Accordingly, the current recording process in the video recorder 50 is maintained.
(6) When a predetermined time elapses after determining a new channel number, the CPU 54 causes the recording unit 55 to change the reception channel and execute recording of the channel after the change. Therefore, the video recorder 50 performs recording processing on the changed channel.
(7) The predetermined time is changed according to the length of time elapsed before the channel change. For example, if the elapsed time is less than 15 minutes, the predetermined time is 15 seconds, and if the elapsed time is 15 minutes or more, the predetermined time is 1 minute. Of course, this is an example, and the present invention is not limited to this.
