Embodiment approach 1
[0144]The present invention assumes three operating systems, namely, satellite system, terrestrial system, and cable system, as the broadcasting system to be constituted. The satellite system uses satellites to transmit broadcast signals to broadcast receiving devices, the ground wave system uses ground wave signal sending devices to transmit broadcast signals to broadcast receiving devices, and the cable system uses wired front-ends to transmit broadcast signals to broadcast receiving devices. way of the device. Since the present invention does not have a direct relationship with the difference of each broadcasting system, it is applicable regardless of the broadcasting system.
[0145] Embodiments of the broadcasting system of the present invention will be described with reference to the drawings. figure 2 It is a block diagram showing the relationship between devices constituting the broadcasting system, and is composed of a broadcasting station side system 201 and three ...
Embodiment approach 2
[0262] The premise of the hardware structure of Embodiment 1 is according to Figure 12 , the descrambler 1804 exists in the TS decoder 1202 . However, the physical connection order of devices handled by the device manager 2205f is not always constant. The hardware structure of this embodiment is according to Figure 15 . exist Figure 15 In the hardware structure shown, as the corresponding Figure 20 As shown, there is no descrambler in the TS decoder 1502 and there is a descrambler 2004 inside the adapter 1511 . In this configuration, the order of physical connection is different from Embodiment 1. Even in this case, the device physical connection management section 3203 manages information on the physical connection order of devices. When the device manager 2205f obtains the connection possibility of the device, it is connected with Figure 37 Similarly, by inquiring the device physical connection management unit 3203 to obtain the connection order of the devices, i...
Embodiment approach 3
[0264] The hardware configuration of Embodiment 1 follows Figure 12 , the device manager 2205f processes [tuner] [PID filter] [section filter] [descrambler] [AV decoder] into devices. But when Figure 12 In , there are other devices such as [display] [speaker]. In addition, there are Figure 12 and Figure 18 devices other than those present in the For example, in Figure 12 present in the TS decoder 1202, except present in Figure 18 In addition to the devices in the TS decoder 1202, there may be a [switching] device that outputs the input MPEG2 transport stream to other devices physically connected to the TS decoder 1202. In addition, there is also a device that deletes unnecessary information from the input MPEG2 transport stream according to the designation of the CPU 1206 , and transfers a partial TS called "virtual TS" to another device physically connected to the TS decoder 1202 . In an HDD recorder with HDD (Hard Disk Drive), "HDD" exists as a device that takes...
