ABSTRACT:
An integrated circuit for manipulating digitized 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, reordering, format conversion, prediction and motion compensation on the pictures in a sequence. The device has memory for temporarily storing sequences to be manipulated and data read from the external memory; a circuit for decoding information about the manipulations to be performed; address circuitry for transferring the data between the device and the external memory; circuitry for configuring the device by means of a remote processing unit; circuitry for processing the data read from the external memory; and circuitry 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.
