Title:
デュアルレイヤフレームコンパチブルフル解像度立体３Ｄビデオ配信
Document Type and Number:
Japanese Patent JP5735181
Kind Code:
B2
Abstract:
3D Images may be encoded into reduced resolution image data in a base layer and enhancement layer (EL) image data in one or more enhancement layers. Different types of data compositions may be used in the EL image data. The different types of data compositions may include unfiltered full resolution image data for one or both of left eye and right eye perspectives, or unfiltered full resolution image data for a color channel, e.g., luminance channel, or unfiltered full resolution image data for selected portions of image frames, or fallback data compositions. Based on deciding factors including bitrate requirements and bandwidth constraints, different types of data compositions may be alternatively used by an upstream device to deliver the best possible 3D image data to a wide variety of downstream devices. The upstream device may inform a downstream device of specific types of data compositions with EL image data descriptors.
