Compression of video signals containing fades and flashes |
摘要 |
<p>A method and encoder for compressing a video signal inserts at least one non-referenced frame to coincide with a duration of a flash on detecting the flash in the video signal. On detecting a fade in the video signal, an order in which frames are coded is changed such that referenced frames are positioned immediately before and after the fade and a pyramidal structure of bidirectionally coded frames are used for the duration of the fade.</p> |
