Each data is extracted and supplied to the SDT and EIT decoder 5. The SDT and EIT decoder 5 decodes the SDT and EIT data extracted by the section filter 4 and outputs a digital satellite broadcast EPG image signal (for example, NTSC signal). The video signal from the MPEG2 decoder 8 and the image signal of the digital satellite broadcasting EPG from the SDT and EIT decoder 5 are added by the adder 10, and are added via the DAC 16 to the terrestrial TV broadcast receiver TV ′.
(FIG. 10) and displayed on the screen. For example, if the channel number in the program list displayed on the screen is selected by controlling the cursor with the remote control transmitter RC or the like, the program is switched to the program designated by the above data.

Next, a conventional EPG for digital satellite broadcasting
The operation of displaying will be described with reference to the flowchart of FIG. First, in step S31, for example, the remote control transmitter R for the digital satellite broadcasting receiver IRD '
When the EPG display command is input with the specific key of the C2 key, in step S32, the SDT data is received and decoded, the presence or absence of the program table is confirmed, and the service name is acquired (self and other streams). Then, in step S33, the EIT data is received, and information such as the program name, start and end times, category, and change in broadcast time in each service is acquired (self and other streams). Then, in step S34, EI
The T data is decoded to obtain an EPG on-screen display (OSD) image signal for digital satellite broadcasting. Next, in step S35, an on-screen display (OSD) image signal of the program guide of the digital satellite broadcast is transmitted from the digital satellite broadcast receiver IRD 'to the terrestrial wave T.
It is supplied to the V broadcast receiver TV 'and the program guide is displayed on the screen. This program guide includes date, time, service name, program name, and the like.

However, when a viewer selects and switches between a terrestrial TV broadcast program and a digital satellite broadcast program on one television receiver TV ', the EPG is used for the digital satellite broadcast. Then remote control transmitter RC
You can comfortably select programs by operating the operation buttons such as 2. However, when watching terrestrial TV broadcasting, you must rely on the print medium to select programs, and equipment in an environment where new technology and conventional technology are mixed. It will force you to operate.

[0008] In digital satellite broadcasting, program viewing reservations can be registered interactively with the EPG screen.
In the case of V broadcasting, since there is no EPG in which each broadcasting station (channel) is integrated, there is no so-called “start / end time and channel number input”, which is conventionally performed in VTR, or so-called search from a print medium. They are forced to operate across devices, such as a method of inputting G-code numbers and a scanner using a barcode.

An object of the present invention is to solve the above-mentioned problems, in addition to an EPG for digital satellite broadcasting, a terrestrial TV.
An object of the present invention is to provide a digital satellite broadcast receiving device that can also use a broadcast EPG.

[0035]

[Embodiment] As another embodiment of the present invention, as an application example in Japan, EPG data for terrestrial broadcasting, which covers all terrestrial TV broadcasting programs that differ for each region as a nationwide version, is transmitted from the communication satellite CS. From the received terrestrial broadcasting EPG data, the viewer selects only channels (broadcasting station names) that can be received in the area of residence and registers them in the memory of the digital satellite broadcasting receiving apparatus of FIG. Thus, after registration, only necessary information can be displayed.

Further, as still another embodiment of the present invention,
It is possible to have software for displaying receivable channels by displaying a schematic national map or a place name on a monitor-TV TV screen and designating a place of residence of a viewer from the map.

As still another embodiment of the present invention,
By inputting the area code of the telephone number of the viewer's residence area, it is possible to have software for specifying the receivable channel.

Further, as still another embodiment of the present invention,
As described above, the viewer does not select from the national version of the EPG information, but sends the EPG for terrestrial broadcasting from the communication satellite.
Conditional reception according to individual viewer's residence area in data I
A conditional access ID added with a D code (an ID code added when a fee is paid for a pay broadcast program) and added to the terrestrial broadcast EPG data received by the digital satellite broadcast receiving apparatus. The code can be displayed by checking the ID code unique to the receiving device.

As described above, terrestrial TV broadcasting is a medium established over a long history, does not compete with digital satellite broadcasting, and it is convenient for viewers to make the best use of each other's strengths. Therefore, it is possible for the viewer to selectively use these programs by using the EPG for digital satellite broadcasting and the EPG for terrestrial broadcasting of the same format, which can provide convenience.

The introduction of digital satellite broadcasting can be applied to all of a plurality of businesses started or planned in each region of the world regardless of domestic and overseas.

It is possible to solve the following problems that frequently occur in reserved recording in terrestrial TV broadcasting. That is, when a program is selected from the information on the print medium and a recording reservation or a viewing start reservation is made, the start and end times of the reserved program will be changed in conjunction with the change in the time extension of sports broadcasting, for example. In particular, in the case of recording reservation, since recording starts before the desired program starts, the recording medium is consumed when the desired program starts, and the entire program cannot be recorded and the recording ends. An accident will occur.

In the program viewing start time reservation system using EPG information, when the program broadcast start time is changed due to the circumstances of the broadcasting station, if the changed information is transmitted by the broadcast wave, the reservation is made. It is possible to check on the software whether or not the reserved program is started at the scheduled time and perform the operation according to the latest information.

Further, in the program viewing start time reservation system using EPG information, the operation contents when it is detected that the broadcast start time is changed by inputting the purpose as information at the time of reservation, Not only can the change time be tracked, but an operation suitable for the purpose can be performed. For example, (1) When the reservation purpose is recording, the start and end times are activated according to the latest information. (2) When viewing is started without recording, when the reserved time comes, character information indicating that the start time of the program has been changed is displayed on the screen or notified by voice. (3) When the purpose of the reservation is to use the alarm clock, the screen and voice are activated at regular intervals regardless of the change in the program content. Such a software is configured to selectively register an operation mode suitable for the user's purpose at the time of reservation. This method is an effective solution not only for terrestrial waves but also for digital satellite broadcasting.

In the section of the configuration and operation description of each of the above-mentioned embodiments, the EPG of the area where reception cannot be performed is requested by the viewer.
It is possible to arbitrarily select to display. (For example, it is possible to obtain program information from a remote location and request a friend living in the area to schedule a video recording.

[0045]

According to the present invention, it is possible to obtain a digital satellite broadcast receiving apparatus that can selectively use both the digital satellite broadcast EPG and the terrestrial broadcast EPG in the same channel selection operation procedure.
