Method, apparatus and system for video delivery using head-end pass through |
摘要 |
Web pages with integrated video are rendered in a head-end without the video content. The head-end creates key frames that depict the graphical representation of web pages, again exclusive of program video. Key frames arriving at set top boxes are written to a background display plane and signal that program video redirected by head-end to set top box should be rendered to an overlay display plane.
