Video telecommunications server and method of providing video fast forward and reverse

摘要: A video telecommunication server for use in providing a fast scan of comprises bitstream store receiving and storing coded input digital bitstream. The further decoder decoding the received and, one embodiment, representation every nth frame said decoded signal is stored depending on desired speed-up rate, where n greater than one. encoder reencodes predictively such that predicted based preceding frame. generated output by represents telecommunication, either forward or reverse direction. receiver control may receive data representing direction rate. In embodiments, an intra provides requesting frames from transmitting at periodic intervals.
