Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a configuration of a digital television broadcast receiver having a function of receiving CS digital broadcast.

[0010] A CS broadcast wave using a communication satellite (CS) is sent to a tuner 2 via an antenna 1 to perform high-frequency processing and demodulation. The output from tuner 2 is DE
The packet is sent to the MUX circuit 3 and the packet is decoded.

In the DEMUX circuit 3, the packet is
It is separated into MPEG data and additional information such as program guide information. The additional information separated by the DEMUX circuit 3 is sent to the system controller 10.

A remote controller signal from a remote controller transmitter 9 is input to a system controller 10 via a remote controller light receiver 11.

The system controller 10 includes a tuner 2
And information for channel selection of the DEMUX circuit 3 and the like.
Further, the system controller 10 displays various operation screens as C
An OSD control signal for causing the RT 20 to perform on-screen display is sent to the OSD display circuit 14. OSD display circuit 1
Reference numeral 4 denotes a multiplexer (synthesis circuit) 18 which generates display data such as a program guide and a menu and outputs the data as an OSD signal.
Send to

The AV decoder 4 demodulates the MPEG data sent from the DEMUX circuit 3. The video signal obtained by the AV decoder 4 is sent to the multiplexer 18 via the video processing circuit 5. Multiplexer 18
Indicates that the video data output from the video processing circuit 5
The display data sent from the D display circuit 14 is superimposed and sent to the video output circuit 7. The video signal output from the video output circuit 7 is sent to the CRT 20.

The audio signal obtained by the AV decoder 4 is sent to the speaker 19 via the audio processing circuit 6 and the audio output circuit 8.

The AC power input from the power outlet 17 is sent to the power supply circuit 16, where it is rectified / stepped down to create DC voltages for various circuits.
C voltage is supplied.

The user performs necessary input operations with the remote control transmitter 9 while watching the display screen on the CRT 20. The system controller 10 can write and manage a plurality of telephone numbers for which registration has been requested by a user's input operation in the nonvolatile memory 12.

Further, the system controller 10 can output a video still request / release signal to the AV decoder 4 by a user's input operation, and can perform still processing or still release processing on the video. Allows the user to release video data (including still video) or stills that he wants to save.

The user transmits video data (including still video) or audio data to be stored in the receiver to the remote controller 9.
Then, the data storage conditions (compression method, program information, reservation / immediate) are set, and in the case of a reservation, information necessary for the reservation is stored in the nonvolatile memory.

The video data or audio data to be stored is temporarily stored in the video processing circuit 5 or the audio processing circuit 6.
Under the control of the system controller 10, data is read out via the AV decoder 4 and compression is performed under the above-mentioned storage conditions. The compressed video data or audio data is stored in the video / audio storage memory 13 together with the storage conditions.

Further, the user operates the system controller 1
By using the modem circuit 15 controlled by the telephone number 0, the telephone number registered in the nonvolatile memory 12 is selected to make a call, and the selected video data or audio data stored in the video / audio memory 13 is selected. Things can be forwarded to the destination.

The modem circuit 15 sends data to a normal analog line, but uses a device for using a digital line such as ISDN or a mobile communication network (PHS, PDC). The predetermined data may be sent by changing to the device.

Further, a non-volatile memory for storing the video data or audio data, and a device for using a digital line such as the ISDN or a device for using a mobile communication network (PHS, PDC) may be a PC card. By converting to a CS receiver, the PC
This can be handled by mounting only a card I / F.

Next, referring to FIG. 2, a description will be given of how the storage processing of the video or audio data according to the present invention is performed.

In FIG. 2, in step 1, a program to be saved is selected by a user's remote control operation. Next, in step 2, a data type such as video (including still) / audio is selected. In step 3, the compression method of the data type selected in step 2 is selected. Step 4
Then, the user selects the start method of executing by reservation or immediate execution. If other than the reservation registration in step 5, step 6
, The process of saving the video / audio memory 13 is immediately executed in accordance with the set contents. When the reservation is registered in step 5, the reservation information is stored in step 7 to be in an execution waiting state, and the storage process is executed in accordance with the set contents stored after the lapse of the designated time.

Next, referring to FIG. 3, a description will be given of how the transfer processing of video or audio data according to the present invention is performed.

In step 8 of FIG. 3, data to be transferred is selected from the video or audio data stored by the processing of the flowchart of FIG. Step 9
Then, the stored data selected in step 8 is reproduced, and its contents are confirmed. In step 10, it is determined whether or not to transfer data. If the data is not to be transferred, the process proceeds to the normal processing of step 11.

When performing data transfer, the process proceeds to step 12, where the user selects a registered telephone number or directly inputs a telephone number. Further, at step 13, a call is made to the telephone number designated at step 12, and at step 14, the line is connected. In step 15, the reproduced video data or audio data is transferred. In step 16, it is checked whether the transfer is completed. If the transfer is not completed, the process is repeated from step 15. If the transfer is completed, the line is disconnected in step 17 and the process proceeds to the normal processing in step 18.

[0029]

As described above, according to the present invention, the video or audio data once captured by the digital broadcast receiver is
The data can be transferred to, for example, a personal computer located at a remote place outside the receiver using a communication line as appropriate, and the contents of images and sounds transmitted by the personal computer can be viewed.
