Abstract:
1. A video processing apparatus comprising: first stage video processing circuitry for receiving input video data and performing one or more processing operations on the input video data to generate an intermediate representation of the input video data; the intermediate representation comprising first and second separate data portions, the first data portion containing transient data derived from the input video data, the transient data only being required for processing of a single video frame, and the second data portion containing long term data derived from the input video data, the long term data being required for processing of at least two video frames; the first stage video processing circuitry being arranged to output the first and second separate data portions for storing in a buffer; second stage video processing circuitry for retrieving the first and second data portions from the buffer and performing one or more further processing operations on the first and second data portions in order to generate output video data; compression circuitry for applying a compression operation to the transient data prior to the first data portion being output to the buffer; and decompression circuitry for applying a decompression operation to the first data portion as retrieved from the buffer in order to obtain the transient data prior to said one or more further processing operations being performed by said second stage video processing circuitry.
