There is an effect.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

  FIG. 1 is a block diagram showing a portable communication device with a television receiving function (hereinafter referred to as a broadcast receiving mobile terminal) 2 of this embodiment. The broadcast receiving mobile terminal 2 displays the video on the basis of the encoded video / audio data obtained by the broadcast reception by the terrestrial digital tuner 230 or the encoded video / audio data read from the memory card 3 or the like inserted in the slot 201. The image is displayed on the display panel 202 and the sound is output from the speaker 203. In this embodiment, the encoded video / audio data is H.264. Suppose that it is H.264 data. Although not shown, a tuner for receiving analog broadcasting is also provided so that terrestrial analog broadcasting can be viewed.

  H. read from the memory card 3 H.264 data is transmitted to the H.264 data via the PCMCIA interface 220 and the system bus 213. H.264 video decoder 204. The terrestrial digital tuner 230 is an H.264 broadcast by this terrestrial digital broadcast. H.264 bit stream data is extracted. H.264 video decoder 204 and audio decoder (MPEG4-AAC) 206.

  H. H.264 video decoder 204 is an H.264 video decoder. The video data obtained by decoding the H.264 bit stream data to obtain quantization coefficients and motion vectors, and performing motion compensation control based on inverse DCT transform and motion vectors is supplied to the graphics controller 205. The graphics controller 205 performs processing such as color adjustment on video data (for example, R, G, B data). The graphics controller 205 also performs OSD (on-screen display) processing for displaying characters (operation buttons, menu screens, message screens, etc.) output from the CPU 209 on the liquid crystal display panel 202. The audio decoder 206 decodes the audio code data in the bit stream to generate audio data. SDRAM 210 is H.264. It is used in the above processing of the H.264 video decoder 204.

  The LCD controller 207 drives the liquid crystal display panel 202 based on the video data supplied from the graphics controller 205. The D / A converter 208 receives the audio data output from the audio decoder 206 and performs D / A conversion to generate a right (R) sound analog signal and a left (L) sound analog signal. This is given to the speaker 203.

  The main body key 214 is an operation button, a cross key (direction key), a numeric keypad, or the like. Operation information for the main body key 214 is given to the CPU 209 via the interface 215 and the system bus 213. Note that a touch panel may be provided as a key. The CPU 209 executes necessary processing based on the operation information. A flash ROM 218 and an SDRAM 219 are also provided.

  The CPU 209 performs data transmission / reception using the network when the PHS data card 4 is installed in the slot 201, control of each functional unit based on the received data, read / write control of the FlashROM 218 and the SDRAM 219, and the like.

  The processing by the CPU 209 will be further described. For example, when the CPU 209 detects that the recording button provided on the main body key 214 is pressed during broadcast reception, the CPU 209 records the program video of the received program in a memory (FlashROM 218 or memory card 3 or the like). The program video to be recorded is the image (still image) at the moment when the record button is pressed, the image (movie) for a predetermined time after the record button is pressed, or the button is not pressed after the record button is pressed An image (moving image) until the state is reached. Further, by loading the PHS data card 4 in the slot 201, page browsing using electronic mail or the Internet can be performed. Accordingly, the broadcast receiving mobile terminal 2 can be used as a net terminal in addition to watching TV or playing a video player. Although not shown, a server (external device) for providing program video of the program is installed on the network, and the broadcast receiving mobile terminal 2 accesses the server to transmit the program video of the program. And request (save) the program video. For example, the server may be provided with program video data of a broadcast program from each broadcast station and stored in a storage, or may be provided with a plurality of tuners to receive and record a program of each broadcast station.

  By the way, while watching the program by the broadcast receiving mobile terminal 2, it may enter a place where the TV broadcast wave cannot be received (such as behind a building) or may be out of the broadcast area. (Program recording) cannot be performed. Also, when there is no free memory space, program recording cannot be performed. Accordingly, in such a case, if the program video of the program can be reacquired, reacquisition is performed. In addition, rather than storing a noisy program video as it is, if a high-quality program video without noise can be reacquired, it will be reacquired.

  In the present invention, in such a case, the server is accessed, and the program video and the like that could not be saved in the received program are reacquired from the server. For this reason, the broadcast receiving mobile terminal 2 accesses the server by the PHS data card 4 as described above. Of course, the server may be accessed through a wireless network using a mobile phone function.

  In the following, a process related to recording a program video of a received program and a process for re-acquiring the program video for the server will be further described.

(1) The CPU 209 determines whether there is a problem in storing the received video. The CPU 209 stores information specifying the received program and information specifying the video to be stored in the memory (FlashROM 218 or the memory card 3) when it is determined that there is a problem. CPU 209 automatically (automatically when it is determined that there is a problem, or automatically when a space exceeding a predetermined threshold is created in the memory) or a user operation for acquiring a program video The information stored in the memory (information specifying the received program and information specifying the video to be stored) is transmitted to the server using the PHS data card 4 to transmit the program video. Request. The received program can be specified by the channel number and time, for example. The video to be saved can also be specified by the time when the recording button is pressed, the pressing time, and the like. That is, if the server can obtain information such as 6ch 16:50:00 to 16: 5: 10, the program video to be transmitted can be determined. A correspondence table for knowing the broadcast station name and the broadcast station ID assigned to each broadcast station from the channel number is provided, and the server that obtains the broadcast station name and broadcast station ID determines the channel number. Also good. It is also possible to acquire program information such as a program name from the PSI / SI of digital broadcasting, give this to a server, and the server can determine the program from the program name. Also in analog broadcasting, EPG data (broadcast station name, program name, etc.) inserted as digital data during the vertical baseline period of a composite video signal obtained by demodulating radio waves is taken out and given to the server You can also. Note that ADAMS-EPG is known as an EPG service in analog broadcasting.

(2) When the CPU 209 determines that the received video cannot be stored because the free space of the memory (FlashROM 218 or memory card 3 or the like) is small (below a predetermined threshold value) or a reception failure occurs, video reception If it is not possible, it is determined that there is a problem. At this time, the image storing process to the memory is not executed. Of course, information specifying the received program and information specifying the video at the time of the save operation are recorded. When the reception failure occurs and the video cannot be received, it is when the video is not decoded if it is a digital broadcast, and when the synchronization signal is not detected if it is an analog broadcast.

(3) The CPU 209 determines that there is a problem when the image quality level of the received video is equal to or less than a predetermined threshold, and executes the video storage process of the received program. The image quality level can be determined based on the reception intensity of broadcast radio waves, the error occurrence rate when generating a transport stream, the S / N ratio, and the like. Since the program video can be acquired for the time being, it is saved, but it is not preferable to store the program video with poor image quality as it is, so in this case as well, the program video from the server must be re-acquired. Do. When storing a program video in which the image quality level of the received video is equal to or lower than a predetermined threshold, an icon indicating that the program video has a quality level of the received video equal to or lower than the predetermined threshold is displayed on the liquid crystal display panel 202. Also good. This icon display can also be used as a message prompting the user to operate a program video transmission request.

(4) When the image quality level of the received video is equal to or lower than a predetermined threshold, the CPU 209 executes message display processing that prompts the user to perform a program video transmission request operation. The message may include “Please try to obtain a program video from the server”. Message display processing can be performed by OSD processing. Note that when the program video cannot be reacquired from the server, a message indicating that the program video could not be reacquired may be displayed.

(5) The CPU 209 inquires and acquires information indicating whether or not the program video of the received program can be acquired from the server. The CPU 209 executes a message display process that tells whether the program video of the received program can be acquired from the server. The message can include contents such as “program video can be acquired from the server” or “the program video does not exist on the server”.

(6) When receiving a digital television broadcast, the CPU 209 can also perform the following processing. The CPU 209 acquires information indicating whether the program video of the received program can be acquired from the server from the digital television broadcast. On the broadcast station side, information indicating whether the program video of the received program can be acquired from the server may be incorporated in the PSI / SI or the like. The CPU 209 executes a message display process that tells whether the program video of the received program can be acquired from the server.

  As described above, when the program video of the received program can be obtained from the server, the image compression degree (less for the received program) is higher than the image compression degree performed when the program video of the received program cannot be obtained from the external device. The video data may be generated with the data amount. According to this, it is possible to save with low image quality for the time being, and it is possible to re-acquire the program video of the received program from the external device later.

(7) The CPU 209 executes message display processing that prompts the user to perform a program video transmission request operation when the remaining capacity of the memory exceeds a certain threshold. When the remaining capacity of the memory exceeds a certain threshold, when another program video is deleted by a user operation, a program video compression process is performed to reduce the data amount of some program videos by the user operation. Occasionally occurs. Along with the message, the size (number of bytes) of the storable program video, in other words, the free space of the memory may be displayed.

(8) The CPU 209 executes message display processing that prompts the user to perform a program video transmission request operation when the user performs an operation for viewing a program video (program video playback). In addition, a list of received received programs (a screen for displaying what kind of program video exists prior to playback (a screen such as an icon or a program name)) is displayed by the processing of the CPU 209. be able to. In this list display, programs that could not be received, programs that were not saved due to insufficient memory, and programs that were saved with low image quality differed from other normally recorded programs (differences in color, marks, etc.) May be displayed. When the user performs an operation for viewing the program video, for example, the program video folder is specified on the menu screen, the thumbnails in the specified program video folder are displayed, and the displayed thumbnail is displayed by the user operation. It can be when the designated key is pressed when designated. Of course, when the program video folder is specified, or when a thumbnail (character notation such as date and time of acquisition or program name if a program video does not exist) is specified, the user performs an operation for viewing the program video. Sometimes it is good. It should be noted that the color of the thumbnail frame may be color-coded such as red for a program video whose image quality level is a predetermined threshold or less, and green for a program video that is not. When a program video request is made without designating a specific thumbnail in the program video folder, the program video request may be automatically made only for a program video whose image quality level is a predetermined threshold value or less.

(9) When receiving a digital television broadcast, the CPU 209 can also perform the following processing. The CPU 209 stores, in the memory, information proving viewing obtained from the digital television broadcast when the program is received. Then, the CPU 209 also transmits information for proving the viewing to the server. On the broadcast station side, for example, a number string (key) that is different for each program may be incorporated into PSI / SI or the like as information for certifying the acquired viewing. The server responds to the program video transmission request when the numeric string (previously held) in the requested program video program matches the numeric string transmitted from the terminal 2. Such a configuration is significant, for example, when a program video re-acquisition service is provided only to those who have watched the program.

(10) The CPU 209 may acquire the information that becomes the device certificate or the user certificate from the storage unit that stores the information that becomes the device certificate or the user certificate, and may also transmit this information to the server. As the storage means, a SIM (UIM) card can be used. Such a card is a CPU card with a built-in OS into which telephone subscription right information (telephone number) is written. For example, the CPU 209 transmits the card ID of the card to the server as a device certificate or a user certificate. As the storage means, a memory in which user's biometric information (fingerprint information or the like) is written can be used. Such a configuration is significant, for example, when a program video reacquisition service is provided only to a person who has a service provision contract. Whether or not the user has a service provision contract is determined based on whether the device certificate or user certificate registered on the server side matches the transmitted device certificate or user certificate. Alternatively, whether or not the user has a service provision contract is determined based on whether or not the biometric information registered on the server side matches the transmitted biometric information. The server responds to a program video transmission request when the device certificate or biometric information registered in advance matches the device certificate or biometric information transmitted from the terminal 2.

(11) When receiving a digital television broadcast, the CPU 209 can also perform the following processing. The CPU 209 acquires information indicating whether the program video of the received program can be acquired from the server from the digital television broadcast. The CPU 209 reduces the amount of data (for example, image compression processing such as pixel thinning) for the program video that can be acquired from the server, and compresses and saves the program video in the memory. It is desirable to perform such processing when the free space of the memory is below a predetermined threshold. Since the program video whose data amount is not reduced can be acquired again from the server, the program video may be downloaded from the server when necessary.

(12) Among the program videos stored in the memory, the CPU 209 compresses and saves the program video designated by the user while reducing the data amount. When the free space in the memory is equal to or less than a predetermined threshold, it is desirable to display the message on the screen and prompt the user for such processing. Since the program video whose data amount is not reduced can be acquired again from the server, the program video may be downloaded from the server when necessary.

  FIG. 2 shows a processing example of the CPU 209. When the broadcast video is received (step S1), when the user presses the recording button (step S2), the CPU 209 determines whether or not the free space of the memory is larger than a predetermined threshold (step S3). If the free space is large, the program video is stored in the memory (step S5). On the other hand, if the free space is small, only the information specifying the received program and the information specifying the video at the time of the saving operation (meta information) are created (step S4) and stored in the memory (step S6).

  FIG. 3 shows a processing example of the CPU 209. When the user performs an operation for viewing the program video, specifically, a thumbnail on the program video folder is specified (if the program video does not exist, a character notation such as acquisition date and program name) (step) In step S11, the CPU 209 determines whether a program video exists (step S12). When the program video exists, it is determined whether or not the program video is deteriorated (whether the image quality level is equal to or lower than a predetermined threshold) (step S13). When the program video is deteriorated, a message for prompting update (re-acquisition) of the program video is displayed (step S14). Next, it is determined whether or not a process for executing update (re-acquisition) of the program video has been performed (step S15). When the program video is not updated and when the program video is not deteriorated, the program video is read from the memory (recording unit) (step S16), and the program video is displayed on the liquid crystal display panel 202 (step S17). On the other hand, when the program video is updated (YES in step S15) and when the program video does not exist (NO in step S12), the meta information is read from the memory (recording unit) (step S18). Then, the meta information is transmitted to the server (step S19). A process of downloading a program video from the server is performed (step S20). Then, the downloaded program video is stored in the memory (recording unit) (step S21), and the process proceeds to step S16.
