Embodiment approach 1
[0036] figure 1 is a block diagram showing the structure of the digital broadcast receiver 1, figure 2 It is a block diagram showing the internal configuration of the video selection and synthesis unit 50 of the digital broadcast receiver 1 . also, Figure 3-1 with Figure 3-2 It is a schematic diagram explaining the operation when the same program is displayed on two monitors, Figure 4 with Figure 5 It is a flowchart showing the operation of the digital broadcast receiver 1 .
[0037] In addition, in Figure 3-1 with Figure 3-2 In , some structures are omitted for convenience of description.
[0038] Such as figure 1 As shown, the digital broadcast receiver 1 according to Embodiment 1 includes a first broadcast receiving unit 10 and a second broadcast receiving unit 20 as a plurality of receiving units, a digital decoding unit 30, an audio selection unit 40, a video selection and synthesis unit 50, and a second broadcast receiving unit 20. An output control unit ...
Embodiment approach 2
[0099] The digital broadcast receiver 1 according to Embodiment 1 has explained the configuration in which two broadcast receiving units display a main screen and a sub screen on each of a plurality of displays, but the digital broadcast receiver 1 according to Embodiment 2 will be described as follows: Explanation of the structure: Three broadcast receiving units are provided, and the main screen and the sub screen are displayed on each display by using two broadcast receiving units, while one broadcast receiving unit accumulates program still images of other broadcast programs, and makes all The accumulated program still images are sequentially displayed on each display as new sprites.
[0100] In addition, about the same structure and operation as Embodiment 1, the same code|symbol is attached|subjected to each part, and description is abbreviate|omitted.
[0101] Figure 9 is a block diagram showing the structure of the digital broadcast receiver 1, Figure 10 is a block...
Embodiment approach 3
[0118] In Embodiment 2, a configuration is described in which program still images ts3m of receivable broadcast program videos ts3 are accumulated by broadcast receiving unit 100 that has not received broadcast programs, and the accumulated program still images ts3m They are sequentially read out to be displayed on the sub-screen, and in Embodiment 3, an example in which program still images are periodically accumulated using an unused broadcast receiving unit will be described.
