Embodiment approach 1

[0064] figure 1 It is a diagram showing a configuration example of a stereoscopic video transmission system for transmitting stereoscopic video (hereinafter referred to as 3D (Dimensional) video) in this embodiment. exist figure 1 Among them, the stereoscopic image transmission system 1 includes: an image recording and reproducing device (hereinafter simply referred to as "recording and reproducing device") 100 as an image output device capable of reproducing stereoscopic images, and an image display device capable of displaying stereoscopic images (hereinafter referred to as "display device") 100. device")200. The recording and reproducing device 100 and the display device 200 are connected by an HDMI cable 205 .

[0065] The recording / playback device 100 is, for example, a DVD recorder, and includes an optical disc 101 , a recording / playback unit 102 , a codec (codec) 103 , a format conversion unit 104 , and an HDMI transmission unit 110 . The 3D compressed video data rec...

Embodiment approach 2

[0124] Next, use Figure 14 Embodiment 2 of the present invention will be described. Figure 14 It is a diagram showing a configuration example of the stereoscopic video transmission system 2 in this embodiment. The difference between the 3D video transmission system 2 of this embodiment and the first embodiment is that the video output device is changed from the recording and reproducing device 100 to a tuner (tuner) 300 . Since the other components are the same, the same reference numerals are given and descriptions thereof are omitted.

[0125] A tuner 300 as a video receiving device includes a receiving unit 305 , a format converting unit 304 , and an HDMI transmitting unit 310 , and is connected to an antenna 301 , a coaxial cable 302 and an Internet (Internet) 303 . The 3D video broadcasted by a broadcasting station (not shown) is received by a reception unit 305 as a video acquisition unit via an antenna 301 in a predetermined reception format. The received 3D video ...

Abstract

With a recording and reproduction device, 3-D compressed video data recorded on an optical disk are reproduced by a recording and reproduction unit and are restored to baseband 3-D video data by a codec. A format conversion unit converts an optical disk recording format to an HDMI transmission format matching the display capability, acquired beforehand, for a display device and outputs the data. A format conversion unit in the display device converts a 3-D video data transmission format received via an HDMI cable to a display format. A display control unit displays the 3-D video data that have been converted to the display format on a display panel.

Description

technical field [0001] The present invention relates to a stereoscopic image transmission system for transmitting stereoscopic images, an image display device and an image output device constituting the stereoscopic image transmission system, and in particular to a stereoscopic image transmission system, an image display device, and an image transmission system for transmitting stereoscopic images through an interface conforming to the HDMI standard. output device. Background technique [0002] In recent years, various methods have been proposed in order to give television images a three-dimensional effect. In these methods, the principle of binocular parallax is used to alternately switch in space or time on a display and prompt the image of the left eye and the image of the right eye. The viewer wears special glasses or directly uses the naked eye to watch. This enables a stereoscopic image to be obtained. [0003] In addition, recently, devices having HDMI terminals con...
