摘要:
The present invention provides a playback apparatus for playing back one combination video by combining a broadcast video with any additional video not determined by a fixed position relative to the broadcast video. The playback apparatus comprises: a first receiving unit that receives, via a broadcast wave, a broadcast video composed of broadcast images, each broadcast image being a portion of a frame image among a plurality of frame images constituting the original video; a second receiving unit that receives an additional video composed of remaining images, each remaining image being the remaining portion of the frame image; an arrangement information acquiring unit that acquires arrangement information indicating an arrangement of the broadcast image and the remaining image in the frame image; and a playback unit that reproduces and plays back the frame images by arranging the broadcast images and the remaining images based on the arrangement information.

A data generating apparatus 100 includes: an acquiring unit 101 configured to acquire a frame image; a setting unit 109 configured to set prohibition information showing a region on the frame image in which superimposition of an additional image is prohibited, the prohibition information being used when a playback apparatus superimposes the additional image on the frame image for playback; and a multiplexing unit 104 configured to multiplex the frame image and the prohibition information to generate data. A receiving apparatus 400 includes: a receiving unit 401 configured to receive data having been generated by multiplexing the frame image and the prohibition information; a separating unit 402 configured to separate the frame image and the prohibition information from the data; an acquiring unit 409 configured to acquire the additional image; and a superimposing unit 407 configured to superimpose the additional image on the frame image based on the prohibition information.

Disclosed is a playback device capable of seamlessly playing back 3D and 2D videos. The playback device plays back 3D video streams including a base-view video stream and a dependent-view video stream. When performing stereoscopic playback using the 3D video streams, the playback device outputs picture data pieces obtained by decoding the base-view video stream and the dependent-view video stream to a display device. When performing 2D playback using the 3D video streams, the playback device outputs each of picture data pieces obtained by decoding the base-view video stream to the display device twice in succession. This way, an output frame rate at which the 2D playback is performed matches an output frame rate at which the stereoscopic playback is performed.
摘要:
To provide a reception and playback device capable of playing back a program in viewer's desired display mode. The reception and playback device receives, with respect to a program that is currently played back in a first display mode, a switching instruction to switch from the first display mode to a second display mode, receives switching permission information indicating whether switching of a playback target stream of the program is permissible from a first stream to a second stream respectively corresponding to the first display mode and the second display mode, when receiving the switching instruction, judges whether switching of the display mode is permissible from the first display mode to the second display mode based on the switching permission information, when judging affirmatively, switches from the first stream to the second stream to perform playback using the second stream, and when judging negatively, performs playback using the first stream.
摘要:
To provide a transmission device that enables playback with respect to the same program in accordance with a viewer's viewing environment. The transmission device stores therein 3D access information and 2D access information respectively relating to access to a 3D stream and a 2D stream that are simulcast, and generates and transmits a data stream including the 3D access information and the 2D access information.

摘要:
A video processing device overlays appropriate presentation data over video images, even if the size of the display area for 3D video images differs from the size of the display area for presentation data that is to be presented with the 3D video images. The video processing device generates left- and right-view images from a 3D video stream, enlarges presentation data obtained from a relevant data stream to scale its display size to match the display size of video images, applying an offset value, which is determined to cause a specific parallax, to the thus enlarged presentation data to generate left- and right-view presentation data, and overlays the left-view presentation data over the left-view images and the right-view presentation data over the right-view images to display video images resulting from the overlaying.
摘要:
A data broadcast display device guarantees stereoscopic perception by the user of a displayed 3D data broadcast image, while alleviating the discomfort a user experiences due to a delay in display. The data broadcast display device includes a reception unit that receives object data for generating the left-view and right-view objects, a display data generation unit that generates the left-view and right-view objects using the received object data while providing notification upon completion of the generation of each object, and a display control unit that determines, at predetermined time intervals, whether the notification has been received for both the left-view and right-view objects, includes both the left-view and right-view objects in a data broadcast image for display when determining affirmatively, and includes neither the left-view nor the right-view object in the data broadcast image for display when determining negatively.
