The invention relates to a method for encoding/decoding a video stream including a plurality of images (A, B, C) in a video processing apparatus having a processing unit (11) coupled to a first memory (12), further comprising a second memory (13), comprising the steps: providing a subset of image data stored in the second memory (13) in the first memory (12), —simultaneous encoding/decoding of more than one image (B, C) of the video stream, by accessing said subset, wherein the simultaneously encoding/decoding is performed by access sharing to at least one image (A). For reducing the traffic or the number of access to second memory (13) an apparatus is proposed including: a processing unit (11) for performing an encoding/decoding process of video data; a first memory (12) coupled to the processing unit (11) for storing image data required for encoding/decoding of video data, —a second memory (13), wherein the video stream includes a plurality of images (A, B, C); the first memory (11) is adapted to store a subset of image data of the second memory (13) in the first memory (12) and the processing unit (11) is adapted to simultaneously encode/decode more than one image (B, C) of the video stream by accessing said subset of image data in the first memory (12), wherein the simultaneously encoding/decoding is performed by sharing access to at least one image. |
