Estimating the term…
Methods of operating a digital video recording and playback device to identify trick play data, e.g., data that is intended for use during trick play modes of video playback device operation such as fast forward and reverse, by recording headers containing specific trick play information along with the trick play data are described. In one embodiment, the recording of headers which identify data as data intended for use during trick play as opposed to normal play operation is described. In addition to identifying data recorded data as normal play or trick play data headers associated with recorded data may identify the speed and direction of video tape recorder operation during which the specific data associated with the header is intended to be displayed at. When a data block includes data packets, a header may be used to identify various ones of the data packets as being for use during one mode of trick play operation, e.g., a first fast forward speed of operation, and other packets in the same data block as being for use during a second mode of trick play operation.
A method of recording digital video data on a storage medium to be read back and displayed by a video playback device capable of operating in a normal playback mode and a plurality of trick playback modes of operation, the method of recording comprising the steps of:
A method of recording digital video data on a tape in a pattern that permits sufficient data, to generate recognizable portions of images, to be read from the tape by a video tape recorder playback device operating in any one of a plurality of playback modes including a normal playback mode and one or more trick play playback modes, wherein the tape moves at a normal tape speed during normal playback mode and at a tape speed which is a multiple the normal playback speed during the trick play playback modes, the method comprising the steps of:
A video playback device, comprising:
A video tape playback circuit, comprising:
A method of recording digital video data on a storage medium in a pattern that permits sufficient data, to generate recognizable portions of images, to be read from the storage medium by a video playback device operating in any one of a plurality of playback modes including a normal playback mode and a trick play playback mode, the method comprising the steps of:
A pre-recorded video tape for use in a video playback device capable of operating in a normal playmode of operation and at least one trick play mode of operation, the tape comprising:
