Fig. 1 is a block diagram showing a portable digital broadcast receiver of the present embodiment.

As shown in FIG. 1, the digital broadcast receiver 2 is inserted into the encoded video audio data or the slot 201 obtained by receiving a broadcast by the terrestrial digital tuner 230 and the tuner I / F (interface) 231. The video is projected onto the liquid crystal display panel 202 on the basis of the encoded video audio data read from the memory card 3 or the like, and the audio is output from the speaker 203. The coded video and audio data obtained by the broadcast reception by the terrestrial digital tuner 230 can also be recorded in the memory card 3 or the like. In this recording, not only moving picture recording but also recording (capturing processing) of a still image (for example, I picture) selected under predetermined conditions can be performed. For example, the received image is sequentially updated and recorded for six minutes, or it is determined whether or not the commercial is being broadcast, and the commercial image is recorded.

In this embodiment, the encoded video and audio data are assumed to be MPEG4 data. The CPU 209 inputs and analyzes the transport stream, supplies the video stream to the MPEG4 decoder 204, supplies the audio stream to the audio decoder (MPEG4-AAC) 206, and supplies the PSI / SI (Program). Separate Specific Information / Service Information) and store it in memory.

The MPEG4 data read from the memory card 3 is supplied to the MPEG4 video decoder 204 via the PCMCIA interface 220 and the system bus 213.

The MPEG4 decoder 204 supplies the video data to the graphics controller 205. This video data is obtained by decoding the bit stream data of MPEG4 to obtain quantization coefficients and motion vectors, and performing inverse DCT transformation or motion compensation control based on motion vectors. The graphics controller 205 performs color tone correction or the like on the video data (e.g., R, G, and B data). In addition, the graphics controller 205 also performs OSD (on-screen display) processing for displaying characters or the like instructed from the CPU 209 on the liquid crystal display panel 202. This OSD processing makes it possible to display various messages. The graphics controller 205 can also perform processing such as reducing the screen size of the broadcast reception video (scaling processing) or displaying a plurality of captured still images in one screen. The audio decoder 206 decodes the speech code data in the bit stream to generate the speech data. The SDRAM 210 is used when performing the above processing of the MPEG4 decoder 204.

The LCD controller 207 drives the LCD panel 202 based on the image data supplied from the graphics controller 205. The D / A converter 208 receives the audio data output from the audio decoder 206, performs D / A conversion, generates an analog signal of the right (R) sound and an analog signal of the left (L) sound, and generates a speaker ( 203).

Information of the operation performed on the main body key 214 is provided to the CPU 209 via the interface 215 and the system bus 213. The CPU 209 executes necessary processing based on the operation information. In addition to the numeric keys and the like, the main body key 214 is provided with a cross key (direction key), a decision key, and the like for selecting buttons displayed on the screen.

It also includes a Flash ROM 218 and an SDRAM 219. The flash ROM 218 stores various setting information set by the user. The battery 221 is a secondary battery and receives power from a charger (not shown) and accumulates it.

The CPU 209 transmits / receives data (Internet connection processing (browser startup), e-mail transmission / reception, etc.) by the PHS data card 4 loaded in the slot 201, control of each functional unit based on the received data, and a flash ROM ( The read and write control of the 218 and the SDRAM 219 are also performed. By the browser, for example, an image based on a predetermined file can be displayed on the LCD panel 202 by connecting to various sites such as a program site and a CM site.

Next, a description will be given of processing in the case where the video display of the digital broadcast program is disabled. Whether or not the image display is disabled can be determined by the received electric field strength of the tuner 230, the error correction situation of the received data, and the like.

(1) When the CPU 209 becomes incapable of displaying a video, the CPU 209 displays the message "Cannot be received." The CPU 209 also extracts program information from the PSI / SI acquired during the reception of the program, and displays the broadcast station name, channel number, program title, and the like as shown in FIG. In addition, if a URI (Uniform Resource Identifier) exists as a program site reading destination in the program information, a program site button for selection is displayed. In addition, a recording reservation button is displayed to prompt the user for the next recording of the program.

When the program site button is operated by the user, Internet connection processing is performed by the PHS data card 4, and an image based on the received file is displayed on the LCD panel 202. When the recording reservation button is operated, recording reservation processing is performed based on the program information of the PSI / SI. When the video display is enabled, the video display processing of the receiving program may be performed. The message " Received and received? &Quot; and the button " YES NO " are displayed. The video display process may be performed. Alternatively, the LED lamp or part of the screen may be flickered to perform video display processing of the received program when a predetermined key is operated. The CPU 209 judges the operation on the button displayed on the screen as follows. That is, if a touch panel is provided, it can be judged by the signal from the touch panel, and if the button is displayed in correspondence with the position of the main body key (so-called soft key), it can be judged by the signal from the main body key. If the cursor is placed on the button with a direction key (cross key) of the main body and the main body determination key is pressed, the determination can be made based on the cursor position.

(2) When the CPU 209 becomes incapable of displaying a video, the CPU 209 displays the message "Cannot be received." The CPU 209 also extracts commercial (CM) information (character information, image information, captured image) acquired during the reception of the program, and displays a sponsor name, a brand name, a promotional text, and the like as shown in FIG. Display. In addition, if a URI (Uniform Resource Identifier) exists as a viewing destination of the CM site in the program information, the CM site button for selection is displayed. When the CM site button is operated by the user, Internet connection processing is performed using the PHS data card 4 to display an image based on the received file on the LCD panel 202. When it becomes a video display possible state, what is necessary is just to perform the process demonstrated by above-mentioned (1).

(3) When the CPU 209 becomes incapable of displaying a video, the CPU 209 displays a message "Cannot be received" on the screen. As shown in Fig. 4A, the CPU 209 screen-displays a plurality of still images (program scenes) captured during reception of the program. When it becomes a video display possible state, as shown in FIG. (B), the video display process of a reception program is performed.

(4) When the CPU 209 becomes incapable of displaying a video, the CPU 209 displays a message "Cannot be received" on the screen. In addition, as shown in Fig. 5, the CPU 209 displays the weather forecast acquired during the reception of the program. The weather forecast information can be acquired, for example, as data of data broadcasting accompanying a program. What is necessary is just to perform the process in (1) mentioned above when it becomes a video display possible state. Not only the weather forecast, but also other news information may be displayed.

The start timing of the processing (1) to (4) described above (i.e., immediately after the video display disabled state, when the video display disabled state continues for a predetermined time, or how long the predetermined time is set) The configuration can be set by the user. In addition, the user can also set which of the processes of (1) to (4) is adopted. On the other hand, the broadcast station may determine (which the program designates) which of the processes of (1) to (4) is adopted. That is, it may be specified by including the program information or the like in advance on the broadcasting station side what information is provided to the user in place of the program video when the video display is disabled. In the OS (operating system), the digital broadcast reception device 2 should prepare an API (application programming interface) in order to execute a process according to the above designation. If there is no designation on the broadcasting station side, the user designation process may be performed. The final image may be displayed for a predetermined time prior to processing when it is determined that the reception program is in a video display disabled state, and user setting may be made for this predetermined time.

6 is a flowchart showing an example of television display processing. If more than a certain number of packet errors occur during the reception of the digital broadcast (YES in steps S1 and S2), a message "Cannot be received" is displayed (step S3). If a predetermined time elapses after this display (YES in step S4), it is determined whether there is a broadcast station designation process (program designation process) (step S5), and if there is a process according to the broadcast station instruction (step S6), The process specified in advance by the user is executed (step S7). In addition, when there is no designation beforehand, you may display a list of the content which can be processed, and let a user select it.
