摘要： Given an input progressive sequence, a video encoder creates a dual-layer stream that combines a backwards-compatible interlaced video stream layer with an enhancement layer to reconstruct full-resolution progressive video. Given two consecutive frames in the input progressive sequence, vertical processing generates a top field-bottom field (TFBF) frame in a base layer (BL) TFBF sequence, and horizontal processing generates a side-by-side (SBS) frame in an enhancement layer (EL) SBS video sequence. The BL TFBF and the EL SBS sequences are compressed together to create a coded, backwards compatible output stream.

摘要： Stereoscopic video data and corresponding depth map data for stereoscopic and auto-stereoscopic displays are coded using a coded base layer and one or more coded enhancement layers. Given a 3D input picture and corresponding input depth map data, a side-by-side and a top-and-bottom picture are generated based on the input picture. Using an encoder, the side-by-side picture is coded to generate a coded base layer Using the encoder and a texture reference processing unit (RPU), the top-and-bottom picture is encoded to generate a first enhancement layer, wherein the first enhancement layer is coded based on the base layer stream, and using the encoder and a depth-map RPU, depth data for the side-by-side picture are encoded to generate a second enhancement layer, wherein the second enhancement layer is coded based on to the base layer. Alternative single, dual, and multi-layer depth map delivery systems are also presented.

摘要： A 3D display is characterized by a quality of viewing experience (QVE) mapping which represents a display-specific input-output relationship between input depth values and output QVE values. Examples of QVE mappings based on a metric of “viewing blur” are presented. Given reference depth data generated for a reference display and a representation of an artist's mapping function, which represents an input-output relationship between original input depth data and QVE data generated using a QVE mapping for a reference display, a decoder may reconstruct the reference depth data and apply an inverse QVE mapping for a target display to generate output depth data optimized for the target display.

摘要： A high resolution 3D image may be encoded into a first multiplexed image frame and a second multiplexed image frame in a base layer (BL) video signal and an enhancement layer (EL) video signal. The first multiplexed image frame may comprise horizontal high resolution image data for both eyes, while the second multiplexed image frame may comprise vertical high resolution image data for both eyes. Encoded symmetric-resolution image data for the 3D image may be distributed to a wide variety of devices for 3D image processing and rendering. A recipient device may reconstruct reduced resolution 3D image from one of the first multiplexed image frame or the second multiplexed image frame. A recipient device may also reconstruct high resolution 3D image by combining high resolution image data from both of the first multiplexed image frame and the second multiplexed image frame.
