Embodiment approach 1

[0035] figure 1 It is a diagram showing the configuration of a digital broadcasting system according to Embodiment 1 of the present invention.

[0036] The digital broadcasting system includes BS / CS digital broadcasting station 1, BS / CS digital broadcasting antenna 2, satellite 3 for relaying electric waves from BS / CS digital broadcasting antenna 2, terrestrial digital broadcasting station 4, terrestrial digital transmitting antenna 5, IP broadcast station group 6 , IP network 7 , BS / CS digital reception antenna 8 installed in user's home, terrestrial digital reception antenna 9 installed in user's home, and digital broadcast receiver (broadcast receiver) 10 .

[0037] First, a broadcast service (current form) realized by broadcast waves based on the MPEG-2 SYSTEMS standard used to construct the digital broadcast system of the present invention will be described.

[0038] In the BS / CS digital broadcast station 1, broadcast data conforming to MPEG-2 SYSTEMS is organized, and b...

Embodiment approach 2

[0065] In Embodiment 1 above, the configuration is shown to select another IP broadcast service in the IP network, but in Embodiment 2, the same service as the redistribution destination is searched from the original broadcast service and performed. The structure of the channel.

[0066] Figure 8 It is a block diagram showing the configuration of a digital broadcast receiver according to Embodiment 2 of the present invention. Hereinafter, the same reference numerals as those used in Embodiment 1 are attached to the same components as those of the digital broadcasting system according to Embodiment 1, and descriptions thereof are omitted or simplified.

[0067] Such as Figure 8 As shown, in the digital broadcast receiver 10, a broadcast wave IF / TS separation unit 121, an SI / PSI management unit 122, an original broadcast channel selection management unit (broadcast wave network channel selection management unit) 123, an IP broadcast network The station information output un...

Embodiment approach 3

[0084] In the above-mentioned second embodiment, the structure of selecting the IP broadcast service based on the data broadcast content of the original broadcast service is shown, but in the third embodiment, it is shown that the original broadcast service is tuned based on the data broadcast content of the IP broadcast service. The structure of the channel. Figure 12 It is a block diagram showing the configuration of an inventive digital broadcast receiver according to Embodiment 3 of the present invention. Hereinafter, the same reference numerals as those used in Embodiments 1 and 2 will be assigned to the same components as those of the digital broadcasting system of Embodiments 1 and 2, and descriptions will be omitted or simplified.

[0085] exist Figure 12 In the digital broadcast receiving apparatus 10 shown, instead of the Figure 8 Shown in the IP broadcast network transfer instruction IF processing section 110 and the IP broadcast service list request IF process...

Abstract

A broadcasting facility P provides a broadcasting network identifier identifying the type of a broadcasting network, a broadcasting facility identifier identifying the broadcasting facility P, a service providing means identifier identifying the service providing means and a service identifier identifying the broadcasting service and a digital broadcasting receiver 10 specifies the broadcasting service by assigning the broadcasting network identifier, the broadcasting facility identifier, the service providing means identifier and the service identifier in a digital broadcasting system provided with a service providing means providing a plurality of broadcasting services emitted from the broadcasting network, the broadcasting facility P provided to the service providing means and the digital broadcasting receiver (10) with which the broadcasting facility P receives the broadcasting service provided through one IP network (7).

Description

technical field [0001] The present invention relates to a broadcast system and broadcast receiving technology related to digital broadcast. Background technique [0002] In a conventional digital broadcasting system, network information of a plurality of connected networks is displayed on the same screen by using a broadcast receiver's inherent function, and the network is switched according to the user's selection (see Patent Document 1). In addition, in order to continuously view and listen to the same service using a plurality of broadcast receivers that can be connected to different networks, the network_id / transport_id is notified between the receivers, thereby realizing the same service channel selection between different terminals / different networks (see patent Document 2). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2006-217430, pages 2 to 8, figure 1 [0004] Patent Document 2: Japanese Patent Application Laid-Open No. 2006-067198, pages...
