Tiles for managing computational complexity of video encoding and decoding

In this paper, we introduce the concept of tiles. Tiles are incorporated into the current design of the High Efficiency Video Coding (HEVC) standard being developed by the Joint Collaborative Team on Video Coding (JCT-VC). In the design, tiles are introduced to support high-level parallelism and also to reduce on-chip memory requirements. This paper describes the tile concept and reports results due to the technique.
