TRICK-MODE STREAM CREATION FOR P V RECORDING

摘要

A method and system respond to a user request for trick-mode play. A decoding device conveys the request to a device for storing a video stream. A current point location in the memory is frozen and the pointer is set back by a preselected back track distance. Then a search for a first target header (300) is begun. The target header (300) is either a sequence or GOP (group of pictures) header. When a target header (300)is found, a data segment is selected which includes the target header (300). This is the start of the trick-mode stream. Further target headers (300-1, 300-2, 300-3) are sought and further data accessed until a full trick-mode stream has been generated.
