MEDIA PIPELINE WITH MULTICHANNEL VIDEO PROCESSING AND PLAYBACK

摘要

PROBLEM TO BE SOLVED: To attain an improvement in a prior technology by providing a media pipeline with two channels for processing sequences of digital still images.

SOLUTION: A blender (54) is provided so as to enable simple effects on these two streams of video data such as dissolves, wipes and chroma keys. Complex arbitrary three-dimensional effects may also be provided using an external interface. Thus, a system for processing the sequences of digital still images to provide real-time digital video effects includes first (50) and second (51) channels for communicating first and second sequences of digital still images at a rate for simulating video. A controller directs still images to one of the first and second channels. The blender (54) provides a combination of the first and second sequences of digital still images at a rate for simulating video.
