DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program receiving apparatus typified by a television receiver, and more particularly to a broadcast for a wide area, such as a satellite broadcast and a terrestrial broadcast, and a program for receiving the broadcast over a wide area. The present invention relates to a reception control technique for selectively receiving broadcasts for some areas.

[0002]

2. Description of the Related Art In the current terrestrial analog broadcasting, each terrestrial station broadcasts a main program uniformly distributed from a key station nationwide, and a CM program and local news for each region. On the other hand, satellite broadcasting has a very large broadcasting area,
Generally, the program content is uniform throughout the country.

[0003] In Japan, satellite digital broadcasting will be started from the end of 2000, and terrestrial digital broadcasting will be started from 2003. In these digital broadcasts, MPEG (Moving Picture Image Coding Experts
Group) standard. In digital broadcasting, not only data for a regular main program or a commercial program but also control data and character data for performing various broadcasting services can be multiplexed and broadcast.

[0004]

Although terrestrial broadcasting is suitable for broadcasting programs having different contents for each region,
To broadcast a program with uniform content nationwide, each ground station must receive the same program data from the key station via a dedicated line, etc., and re-broadcast using its own broadcasting system. It has to be inefficient because it has to be done, and in some areas the program can be delayed for several weeks.

[0005] On the other hand, satellite broadcasting is efficient when broadcasting the same content nationwide. However, basically, as in the current terrestrial analog broadcasting, the main program is nationwide uniform. And CM programs and local news for each region cannot be mixed. As a method for solving such a problem, "Advertising Information Broadcasting Method, Advertising Information Broadcasting System and Receiving Apparatus" is disclosed (JP-A-11-17633).

According to the present invention, on the satellite broadcast side, a target ID is added to each of a plurality of pieces of advertisement information, multiplexed with program data of a main program, and broadcasted. A method is disclosed in which an advertisement is reproduced for each viewer or each receiving terminal by collating with a target ID stored in advance for each viewer or each receiving terminal.

[0007] However, the above method has a serious drawback that the advertisement information for all target IDs must be multiplexed and broadcast at the same time, and the bandwidth is instantaneously widened. Therefore, in order to prevent the bandwidth from being instantaneously widened, the present invention further multiplexes and broadcasts the advertisement information at a different timing first on the broadcasting side, stores the advertisement information in advance on the receiving side, and reproduces the information later. A method of displaying is disclosed.

However, in the above method, a storage device having a storage capacity enough to store the advertisement information is required, which increases the price of the receiver. Thus, the present invention can easily mix programs nationwide and programs for each region without instantaneously increasing the bandwidth and without requiring a storage device for storing advertisement information. It is an object of the present invention to provide a program receiving device, a program receiving method, and a computer-readable recording medium for recording a program receiving program.

[0009]

In order to achieve the above object, a program receiving apparatus according to the present invention is a program receiving apparatus for receiving and reproducing a program, and comprises a first program receiving apparatus comprising a plurality of program receiving apparatuses. A first receiving means for receiving the program via a first transmission path for transmitting the program to a receiving object, and a second receiving means which is a part of the first receiving object and comprises one or more program receiving apparatuses.
A second receiving unit for receiving the program via a second transmission path different from the first transmission path for transmitting the program to a reception target, and a program received by the first receiving unit; At least one of the programs received by the second receiving means is attached with switching information that is information specifying a program received by the other means at a predetermined timing, and further includes the first receiving means, Control means for causing any one of the second receiving means to receive one program; and extracting means for extracting the switching information when the switching information is attached to one currently received program. Wherein the control means, when the switching information is extracted by the extracting means, one of the programs currently received and one specified by the switching information Characterized in that it comprises a switching means for switching the program to be received into the program.

[0010] Thereby, programs transmitted through different transmission paths can be automatically switched and received, so that a uniform program nationwide broadcast by satellite broadcasting or the like can be obtained.
Receiving a mix of regional CM programs and news broadcast by terrestrial broadcasting, etc., common programs broadcast by satellite broadcasting, terrestrial broadcasting, etc., and individual CMs distributed by Internet broadcasting, etc. Programs and news can be mixed and received.

Therefore, the band is not instantaneously widened, and
It is possible to easily mix a program nationwide and a program for each area or individual without requiring a storage device for storing advertisement information.
