Vorrichtung zum Manipulieren von komprimierten Videosequenzen |
摘要 |
An integrated circuit for manipulating digitised video sequences is provided, for use in a system for transmission and reception of compressed video sequences to perform, possibly with the aid of an external memory, re-ordering, format conversion, prediction and motion compensation on the pictures in a sequence. The device (MSM) comprises means (MT1, MT2) for temporarily storing sequences to be manipulated and data read from the external memory; means (DIB) for decoding information about the manipulations to be performed; addressing means (ISS, CM, CME) for transferring the data between the device and the external memory; means (IU, RC) for configuring the device by means of a remote processing unit; means (IHV) for processing the data read from the external memory; means (SU) for arranging the output sequences in the format required by the function to be performed. A controller may control, supervise and set up the functions to be performed. <IMAGE> |
