Abstract:
A device (V) for encoding and storing video data wherein received picture information is divided into video frames and encoded before said storing, comprisinga first encoder (K1) for coding said received picture information divided into video frames according to an interframe coding,a second encoder (K2) for coding said received picture information according to an intraframe coding,a memory (MEMO), anda control unit (CTRL) for controlling both encoders (K1, K2)for intraframe coding a first frame of said video frames, and thereafterfor interframe coding every frame of said video frames of said received picture information,for intraframe coding only predetermined individual frames of said received picture information,for storing said every interframe-coded frame as well as said intraframe-coded predetermined individual frames in the memory (MEMO),for reading and transmitting an intraframe-coded video data frame followed by a sequence of interframe-coded video data frames for transmission without interruption by intraframe-coded video data frames until a fast forward or fast backward command is received, andfor reading and transmitting one intraframe-coded video data frame of said predetermined individual frames followed by a sequence of interframe coded frames upon receipt of said fast forward or fast backward command.
