Video processing system with shared/configurable in-loop filter data buffer architecture and related video processing method thereof

A video processing method, comprising:

• sharing a data buffer between a plurality of in-loop filters, wherein not all of the in-loop filters comply with a same video standard;
• and
• controlling data access of the data buffer, wherein for each in-loop filter granted to access the data buffer, the data buffer stores a partial data of a picture processed by the in-loop filter;
• wherein at least one of the in-loop filters stores filter-related data into the data buffer when an access right of the data buffer is granted to said at least one of the in-loop filters.

A video processing system, comprising:

• a data buffer, shared between a plurality of in-loop filters, wherein not all of the in-loop filters comply with a same video standard;
• and
• a storage controller, arranged for controlling data access of the data buffer, wherein for each in-loop filter granted to access the data buffer, the data buffer stores a partial data of a picture processed by the in-loop filter;
• wherein the in-loop filters include a first in-loop filter and a second in-loop filter;
• the first in-loop filter is arranged to store a filter-related data into the data buffer when an access right of the data buffer is granted to the first in-loop filter by the storage controller;
• and the second in-loop filter is arranged to store at least a filter-related data into the data buffer when the access right of the data buffer is granted to the second in-loop filter by the storage controller.
