Abstract
A video base layer can contain information pertaining to frame-compatible interlace representations of multiple data categories while video enhancement layers can contain interlace or progressive representations and/or frame-compatible representations of these data categories. Video data are encoded and decoded using layered approaches.
Claims21
A decoding system for decoding a plurality of bitstreams representative of stereoscopic video data, the stereoscopic view further comprising a first view and a second view of the video data, and adapted to be received from an encoding system, the plurality of bitstreams comprising one or more first layer bitstreams representative of at least one first layer, the first layer comprising both the first view and the second view of the stereoscopic video data, and one or more second layer bitstreams representative of at least one second layer, each bitstream comprising data associated with one or more data categories of the video data, the decoding system comprising:
- a first layer decoder that is configured to decode the one or more first layer bitstreams associated with the at least one first layer, wherein the at least one first layer comprises a frame-compatible interlace representation of the one or more data categories, the first layer decoder thus being configured to obtain a reconstructed frame-compatible interlace representation, such that the frame-compatible interlace representation comprises both first and second views that fit within a single frame configure to reproduce a 3-D video image;
- and
- a second layer decoder that is configured to decode the one or more second layer bitstreams associated with the at least one second layer, wherein the at least one second layer comprises one or more progressive representations, each progressive representation being associated with one or more of the data categories, the second layer decoder thus being configured to obtain one or more reconstructed progressive representations, such that the progressive representations are configured to derive enhanced resolution reconstruction of the 3-D video image.
A decoding system for decoding a plurality of bitstreams representative of stereoscopic video data, the stereoscopic view further comprising a first view and a second view of the video data, and adapted to be received from an encoding system, the plurality of bitstreams comprising one or more first layer bitstreams representative of at least one first layer, the first layer comprising both the first view and the second view of the stereoscopic video data, one or more second layer bitstreams representative of at least one second layer, and one or more third layer bitstreams representative of at least one third layer, each bitstream comprising data associated with one or more data categories of the video data, the decoding system comprising:
- a first layer decoder that is configured to decode the one or more first layer bitstreams associated with the at least one first layer, wherein the at least one first layer comprises a frame-compatible interlace representation of the one or more data categories, the first layer decoder thus being configured to obtain a reconstructed frame-compatible interlace representation, such that the frame-compatible interlace representation comprises both first and second views that fit within a single frame configure to reproduce a 3-D video image;
- a second layer decoder that is configured to decode the one or more second layer bitstreams associated with the at least one second layer, wherein the at least one second layer comprises one or more interlace representations, each interlace representation being associated with one or more of the data categories, the second layer decoder thus being configured to obtain one or more reconstructed interlace representations, such that the progressive representations are configured to derive enhanced resolution reconstruction of the 3-D video image;
- and
- a third layer decoder configured to decode the one or more third layer bitstreams associated with the at least one third layer, wherein the at least one third layer comprises one or more progressive representations, each progressive representation being associated with one or more of the data categories, the third layer decoder thus being configured to obtain one or more reconstructed progressive representations.
A decoding system, comprising:
- a first layer decoder that is configured to decode a first layer bitstream associated with at least one first layer of stereoscopic video data stream, the stereoscopic view further comprising a first view and a second view of the video data and the first layer comprising both the first view and the second view of the stereoscopic video data, wherein the at least one first layer comprises a frame-compatible interlace representation of the one or more data categories, the first layer decoder thus being configured to obtain a reconstructed frame-compatible interlace representation, such that the frame-compatible interlace representation comprises both first and second views that fit within a single frame configure to reproduce a 3-D video image;
- and
- a second layer decoder that is configured to decode at least one second layer bitstream associated with at least one second layer, wherein the at least one second layer comprises one or more progressive representations, each progressive representation being associated with one or more of the data categories, the second layer decoder thus being configured to obtain one or more reconstructed progressive representations, such that the progressive representations are configured to derive enhanced resolution reconstruction of the 3-D video image;
- wherein the first layer comprises a frame compatible representation of the video data, and wherein the second layer(s) are structured to be ignored by legacy decoding mechanisms;
- and
- wherein the decoder is installed in at least one of a display, set-top box, and video player device.
