Abstract: A method and apparatus for loop processing of reconstructed video in an encoder system are disclosed. The loop processing comprises an in-loop filter and one or more adaptive filters. The filter parameters for the adaptive filter are derived from the pre-in-loop video data so that the adaptive filter processing can be applied to the in-loop processed video data without the need of waiting for completion of the in-loop filter processing for a picture or an image unit. In another embodiment, two adaptive filters derive their respective adaptive filter parameters based on the same pre-in-loop video data. In yet another embodiment, a moving window is used for image-unit-based coding system incorporating in-loop filter and one or more adaptive filters. The in-loop filter and the adaptive filter are applied to a moving window of pre-in-loop video data comprising one or more sub-regions from corresponding one or more image units.

Abstract: A video operating and processing apparatus includes a memory circuit, a data arrangement unit and a processor. The memory circuit is used for buffering sets of macroblock parameters for operating and processing the video stream, each set of macroblock parameter corresponding to a set of the macroblocks. The data arrangement unit stores the sets of macroblock parameters in the memory circuit, the storing addresses of the memory circuit are determined by a characteristic of the macroblock parameters. The processor is designed for processing the macroblocks according to the sets of macroblock parameters. On processing the macroblocks, the processor needs to reference to sets of macroblock parameters. The data arrangement unit stores the macroblock parameters in the memory circuit with addresses determined by reference to a characteristic of the macroblock parameters, instead of directly storing the macroblock parameters into continuous bits in the memory circuit.
