Methods and architecture for indexing and editing compressed video over the world wide web

摘要

A system and method is provided for editing and parsing compressed digital information. The compressed digital information may include visual information which is edited and parsed in the compressed domain. In a preferred embodiment, the present invention provides a method for detecting moving objects in a compressed digital bitstream which represents a sequence of fields or frames of video information for one or more captured scenes of video.

主权项

1. A method for dissolving an incoming scene of video information which comprises a sequence of fields or frame of compressed video information and an outgoing scene of video information which comprises a sequence of fields or frame of compressed video information using a computer-based tool, comprising:
a. extracting transform coefficients for all blocks of video information which make up a last frame of said outgoing video scene; b. extracting transform coefficients for all blocks of video information which make up the first frame of said incoming video scene; and c. creating a first frame in a dissolve region, said first frame comprising a combination of said transform coefficients of said last outgoing frame and said transform coefficients of said first incoming frame, said dissolve region being made playable as a transition between said outgoing and incoming scenes during playback of a video containing said outgoing and incoming scenes of video information.
