DESCRIPTION

The VP2614 Video De-Multiplexer forms part of the Mitel Semiconductor chip set for video conferencing, video telephony, and multimedia applications. It extracts video parameters and run length coded DCT coefficients from an H.261 bitstream. Elements of the data which have been variable length coded according to the specification are decoded within the device. It produces tagged data, aligned to a macroblock timing structure, in the format needed by the VP2615 Decoder. Side information and status bits are separately made available for the system controller.
