VIDEO OBJECTS CODED BY KEYREGIONS |
摘要 |
A coding protocol provides for coding video data that has been organized as video objects. The protocol provides a keyregion to permit coding of a region of data within the video object having common attributes. According to the protocol a keyregion is identified by a keyregion header, which includes a resync marker that uniquely identifies the keyregion header, a keyregion position signal indicating an origin and a size of the keyregion; and data of the common attribute. Data following the keyregion is coded according to the common attribute. |
