Embodiment approach 1

[0057] In Embodiment 1, a reproduction device capable of outputting a multi-video (multi-screen) signal, which includes two recording media, two video decoders, and two audio decoders, will be described. Here, the multi-video is a video representing multiple kinds of video.

[0058] figure 1 It is a block diagram showing the configuration of the playback device 1000 according to the first embodiment. The playback device 1000 is connected to a display and a speaker (not shown). The display is a display device capable of displaying images. The reproduction device 1000 transmits the generated video signal to an external display not shown, which will be described in detail later. In addition, the reproduction device 1000 transmits the audio signal to the speaker.

[0059] refer to figure 1 , the playback device 1000 includes recording media 1A and 1B, a playback unit 100, an OSD (On-Screen Display: On-Screen Display) unit 4, a video synthesis unit 5, an instruction acceptance...

Embodiment approach 2

[0156] In Embodiment 2, a playback device including 4 tuners, 4 video decoders, 4 audio decoders, 2 external video signal input units, and 2 external audio signal input units will be described.

[0157] image 3 It is a block diagram showing the configuration of a playback device 1000A according to Embodiment 2.

[0158] A playback device 1000A includes a television receiver 200 and playback devices 301 and 302 .

[0159] The television receiver 200 is a video display device capable of displaying multiple videos (multi-screen).

Abstract

A multi-video output unit (9) performs processing for outputting a multi-video indicating a plurality of videos which are each acquired from a plurality of video signals. A playback state assessment unit (7) assesses the playback state of at least one video signal of the plurality of video signals. An audio signal selection unit (8) selects any signal of a plurality of audio signals on the basis of the playback state which has been assessed by the playback state assessment unit (7).

Description

technical field [0001] The present invention relates to a playback device for processing a multi-video representing a plurality of videos, an audio selection method, and an audio selection program. Background technique [0002] In recent years, the demand for thin TVs has increased rapidly around the world in the context of digitization, high-quality broadcasting, and multi-channel broadcasting. In addition, with the further increase in capacity and price of recording media, it is now easy for ordinary users to purchase recording and playback devices equipped with HDDs (hard disk drives) with hundreds of gigabytes or more. Therefore, compared with before, the content that users can see and hear has also increased significantly. [0003] Compared with cathode ray tube TVs, it is easier to enlarge the screen size of thin TVs. As one of the functions to effectively utilize the large screen, for example, there are multiple video simultaneous display technologies represented by ...
