Abstract:

Enhanced dynamic range requires more than 8 bit representation for single color components of pixels. For this purpose, normal color resolution images and high color resolution images are available. Backward compatibility can be achieved by a layered approach using a color enhancement layer, and a conventional image as color base layer. Both have same spatial and temporal resolution. Encoding of the color enhancement layer uses prediction and residual. A methods for optimized color enhancement prediction is disclosed. Color bit depth prediction is done by constructing a polynomial that approximates for all pixels of one color component of a block the color enhancement layer from the color base layer. A predicted version of the high color resolution image and a residual are generated and updated by a residual. The coefficients are compressed and added as metadata to the data stream.

US Classification:

713156, 713157, 713175

Abstract:

A method and apparatus are provided for generating identity data to be provisioned in product devices that are a part of a project. The method includes establishing a template associated with each CA in a hierarchical chain of CAs having a root CA at a highest level in the chain and a signing CA at a lowest level in the chain. The template associated with the signing CA inherits mandatory attribute fields specified in the root CA and any intermediate CA in the hierarchical chain. The mandatory attribute fields are user-specifiable fields to be populated with PKI data. A configuration file is generated upon receipt of an order for digital certificates using PKI data provided by a user to populate the mandatory attribute fields of the template associated with the signing CA. The digital certificates requested in the order are generated using the PKI data in the configuration file.

International Classification:

H04N 7/12

US Classification:

37524012

Abstract:

A multiplexer may produce an MPEG-2 (Motion Picture Experts Group) System standard bitstream comprising views with nonconsecutive view order indexes. In one example, an apparatus includes a video encoder that encodes views of a scene, and a multiplexer that constructs a data structure for signaling that a corresponding MPEG-2 (Motion Picture Experts Group) System standard bitstream includes a first view of the views of the scene associated with a first view order index and a second view of the plurality of views of the scene associated with a second view order index. The first view order index and the second view order index are non-consecutive. The apparatus may further include an output interface that outputs the data structure.

US Classification:

348 42, 382298, 348 51, 37524008

Abstract:

This disclosure describes techniques for generating depth maps for video units, such as video frames or slices video frames. The techniques may be performed by a video encoder in order to convert two-dimensional (2D) video to three-dimensional (3D) video. The techniques may alternatively be performed by a video decoder in order to convert received 2D video to 3D video. The techniques may use a combination of motion and color considerations in the depth map generation process.

Abstract:

A method comprises encoding a first view component of a first view of a multiview bitstream; and encoding a second view component of a second view; wherein the encoding of the second view component enables generating of a reference picture list for the second view component to include at least one of the following: (a) a first field view component based on the first view component or (b) a first complementary field view component pair including the first view component.
