Abstract
Video processing image manipulation and trick play modes provide seamless normal play and trick play functioning. Specifically, a system processes video data including encoded digital packetized data representative of a sequence of individual images and ancillary data identifying characteristics of the individual images. The system involves a pre-processor for parsing the ancillary data to determine characteristics of the individual images prior to storing the encoded digital packetized data. The system also includes a multiplexer for filtering the encoded digital packetized data based on the determined characteristics to identify particular images of the image sequence for storage in a memory and for excluding other images of the sequence from storage.
