Method and apparatus for selecting encoded video data for use during video recorder trick play operation |
摘要 |
Method of operating a digital video tape recorder apparatus that receives encoded and packetized digital video data, depacketizes the received data and decodes the data to the extent necessary to select a subset of the data for use during trick play operation. In one embodiment, the digital video tape recorder includes a data prioritizer for prioritizing the video data according to a preselected prioritization scheme. The apparatus also includes an encoder and re-packetizer for forming the selected subset of received data into transport data packets. The received digital video data is recorded on a tape in tape locations from which data can be read during normal video tape recorder playback operation while the selected subset of the received data is recorded in tape locations from which data can be read during video tape recorder trick playback operation.
