摘要： A content stream comprising video and synchronized illumination data is based on a reference lighting setup from, for example, the site of the content creation. The content stream is received at a user location where the illumination data controls user lighting that is synchronized with the video data, so that when the video data is displayed the user's lighting is in synchronization with the video. In one embodiment, the illumination data is also synchronized with events of a game, so that a user playing games in a gaming environment will have his lighting synchronized with video and events of the game. In another embodiment, the content stream is embedded on a disk.

摘要： When performing inter-layer prediction, the present method and apparatus make predictive inter-layer determinations, such as from the LDR layer to the HDR layer, based on pixels used in the LDR layer for intra prediction of the LDR block using an intra LDR mode and also based on the homologous pixels in the HDR layer for the intermediate intra prediction block using the same intra LDR mode. By using these bases, it is possible to estimate an inverse tone mapping function and then apply this estimated function to the LDR block in order to determine the inter-layer HDR prediction block.
