SEAMLESS TRANSITION BETWEEN INTERLACED AND PROGRESSIVE VIDEO PROFILES IN AN ABR SYSTEM

摘要

A method for seamless transition between interlaced and progressive video profiles may include receiving at a video feeder a stream of video signals for displaying on a display device. The stream of video signals may include segments of one of interlaced fields or progressive video frames. During an interlaced stream, the interlaced fields may be directed to a deinterlacer, and an output of the deinterlacer may be directed to the display device. The output of the deinterlacer may be determined based on previously received interlaced fields from the video feeder. During a transition to a progressive stream, the progressive video frames may be directed to a frame store, and the output of the deinterlacer may be directed to the display device. During a progressive stream, the progressive video frames may be directed to the frame store, and previously stored frames may be directed to the display device.
