Video transmission device, video transmission method, and video playback device

摘要

A video transmission device for transmitting a video image so that a video playback device can recognize a transmission path for an additional-view video image transmittable through various transmission paths, and play back a 3D video image. The video transmission device includes: a storage unit for storing therein video images transmitted through respective virtual channels, and virtual channel information pieces including definition information pieces defining the respective virtual channels; and a transmission unit for transmitting the video images and the virtual channel information pieces through the respective virtual channels, wherein the stored video images include one of two viewpoint images constituting the 3D video image, and, in one of the definition information pieces defining one of the virtual channels through which the one of the two viewpoint images is transmitted, transmission form information indicating a form of transmitting the other one of the two viewpoint images is described.

主权项

1. A video transmission device for transmitting video content to a video playback device, the video transmission device comprising:
a non-transitory memory configured to store therein 3D video content corresponding to 2D video content; an encoder configured to encode images of one of two viewpoints constituting the 3D video content by using a first encoding scheme and generate a video stream of the 2D video content, and to encode images of both of the two viewpoints by using a second encoding scheme that is different from the first encoding scheme and generate a video stream of the 3D video content; and a processor configured to transmit, via a communication circuit, the video stream of the 2D video content, the video stream of the 3D video content, information defining a program relating to the 2D video content, and information defining a program relating to the 3D video content, wherein the information defining the program relating to the 3D video content includes linkage information for identifying the information defining the program relating to the 2D video content, the processor transmits identical-status information by including the identical-status information in the information defining the program relating to the 3D video content, the identical-status information indicating that the images of the one of the two viewpoints correspond to the 2D video content, and the identical-status information is to be received by the video playback device.
