Abstract

PROBLEM TO BE SOLVED: To provide a user interface which is understood easily by users, in order to output one or separate services (programs) to a plurality of devices connected to a receiver at the same time in real time, under the restriction where even through with identical one tuner must be present in a full transport stream(TS) transmitted from one transponder. SOLUTION: A full transport stream outputted from a tuner 2 includes a plurality of services such as programs. When receiving a service (program, music, data broadcasting or the like), a TSP processing section 3 generates a menu to select services, that can simultaneously be received from the full transport stream, and a TV 7 displays this menu. When a user selects services desirably received at the same time, the TSP processing section 3 extracts the selected services from the full transport stream and outputs them to other devices, such as a D-VHS 8 and an MD 9.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving apparatus for receiving digital broadcasting, and more particularly to a receiving apparatus for outputting a service to a plurality of output destinations.

[0002]

2. Description of the Related Art In a conventional digital broadcast receiving apparatus, in order to output different services (programs) to a plurality of devices connected to the receiving apparatus, a partial TS to be output to respective output destinations is used as an original broadcast. Multiple tuners were used to extract from. Further, it has not been considered to utilize the remaining service (TS) except for the TS of the service in use from the full TS (TS: transport stream) as a service.

When a conventional program is selected, a program guide transmitted by broadcasting is displayed, and a user makes a selection using the program guide.

[0004] However, when trying to receive a certain program and another program at the same time, in the case of a service (station, NHK and TBS, etc.) included in different transponders, it cannot be obtained from one tuner at the same time. . In other words, it is often thought that a user can receive only one program at a time with one tuner.

However, within the limits of a plurality of services (programs) included in the range of one transponder obtained by one tuner, it is possible to receive a plurality of programs at the same time and output or record them to different devices. It was possible,
A user interface and a device for realizing it have not been considered so far.

1394 interface 6 for converting and outputting to E1394 format, decoding output of decoder 4 and UI /
The image signal of the operation screen from F5 is combined with the analog T
It comprises a synthesizer 10 for outputting to V.

The frequency demodulated by the tuner 2 is in units of one transponder (trapon). One transponder has one TS for DVB (Digital Video Broadcasting)
However, in Japan, multiple TSs are included. For example, in a BS, one transponder includes four video TSs, four music TSs, and three data broadcasting TSs. All TSs transmitted by one transponder are called full TSs.

The analog output of the digital broadcast receiving apparatus 1 is input to the TV 7, and when a program is specified by the user, the specified program (the above-mentioned service = partial TS information) is displayed. In addition, IEEE13
94 interface 6 is D-VHS (digital VHS)
8 and an MD (MD: Mini Disc) 9 in a daisy chain.

Next, the operation of the digital broadcast receiving apparatus thus connected will be described.

It is assumed that the user has previously given an instruction to record the program A, which is one of the services, on the D-VHS 8 using a remote controller or the like. Digital broadcasting services include T
There are V programs, music, data broadcasting, and the like.

The tuner 2 demodulates one transponder including the program A designated by the user shown in FIG. 2A from the signal supplied from the antenna, and sends a full T
Output S. The TSP processing unit 3 receives the input full TS
2B, only the packet related to the program A specified by the user is extracted to create the partial TS shown in FIG.
Output to D-VHS 8 via EE1394 interface 6. D-VHS8 is transmitted from the TSP processing unit 3 to the IEEE.
The partial TS supplied via the E1394 interface 6, that is, information of the program A is recorded.

At this time, the TSP processing unit 3 transmits the program information of the program to be transmitted from the full TS to the full TS shown in FIG.
Output to I / F5. The UI / F5 is a TSP processing unit 3
Then, a program name, a service name, and the like are extracted from the SI information of the full TS input from, and a screen for performing the display shown in FIG. Then, the user selects all the programs or services included in the full TS extracted by the tuner 2 in FIG.
, And the user can select a program or service from these. What is necessary is just to select program A to D-VHS8. At the same time, the TV screen is arbitrarily selected from among those shown in FIG. 3 and selected, and displayed on 7 via the TSP processing unit 3, decoder 4, and synthesizer 10 in FIG.

At this time, an instruction for displaying a screen for simultaneously selecting a service to be received on the TV 7, for example, by pressing a predetermined button on a remote controller, the screen for selection is displayed on the TV 7 via the synthesizer 10. You. This selection processing is not an essential part of the present invention, and thus description thereof is omitted, but any of various conventionally known methods may be used. Further, the same service may be received by a plurality of devices.

The screen shown in FIG. 3 is a screen for the user to select a service that can be further received or recorded, and a service to be received at the same time is selected by a remote controller (not shown). The screen shown in FIG. 3 for selecting this service may display a music program name if the service is a music program, or may display a data service name if the service is a data broadcasting service. In the present embodiment, the synthesizing unit 10 performs the synthesizing, but instead, the signal may be switched to the signal from the operation screen of the UI / F 5 and output to the TV 7 only when the selection screen is displayed.

Here, the user selects the option of recording program A on D-VHS 8 and watching program C on TV 7 in FIG.
It is assumed that the operation is performed using the screen shown in FIG. The TSP processing unit 3 converts the partial TS of the program A shown in FIG.
At the same time as recording on the D-VHS 8 via the 1394 interface 6, the partial T of the program C shown in FIG.
S is sent to the decoder 4. The decoder 4 depackets the program C, decodes it, converts it into an analog signal, and outputs it to the TV 7 via the synthesizer 10. Thereby, the TV 7 displays the program C.

At this time, unless a plurality of programs are selected from the program information included in the full TS of one transponder as in the prior art, a plurality of programs cannot be received at the same time. The present invention enables a method in which a single tuner can simultaneously designate and transmit a plurality of programs (services) for each output destination.

As described above, with a simple interface operation by the user, it is possible to provide a receiving apparatus that outputs the same or another service (such as a program) to a plurality of devices connected to the receiving apparatus even with one tuner. .

Next, for example, the user sets program A to D-VHS8.
The operation in the case of outputting the music F, which can receive the service at the same time, to the MD 9 while recording the music F into the MD 9 will be described.

When the user is recording program A in the D-VHS 8, the user instructs the TV 7 to display a screen for simultaneously selecting a service to be received, such as pressing a predetermined button on a remote controller. Thus, a selection screen as shown in FIG. 3 is displayed on the TV 7 via the synthesizer 10.

Here, it is assumed that the user has selected using the screen shown in FIG. 3 to record the music A on the MD 9 while recording the program A on the D-VHS 8. The TSP processing unit 3 transmits the partial TS in which only the packets related to the program A and the music F shown in FIG. Is done. This is because the IEEE1394 interface 6
The packet related to program A shown in FIG.
h: channel) and a packet related to music F in ch-m
D-VHS 8 and MD 9 can receive only ch-n packets and ch-m packets, respectively. D-VHS 8 can record program A, and MD 9 can record music F. .

As described above, a plurality of partial TSs can be simultaneously extracted from a full TS and another service can be simultaneously supplied to a plurality of output destinations. There is a limitation that even one tuner must be present in the full TS transmitted by the same transponder, but the same or different services (programs) are simultaneously output in real time to a plurality of devices connected to the receiving device. To provide a user interface that is easy for the user to understand.

Although the embodiment of the present invention has been described with reference to digital broadcasting in general, it can be applied to any of BS digital broadcasting, terrestrial digital broadcasting, cable digital broadcasting, and the like.
