Title:
DECODING DEVICE, DECODING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/087860
Kind Code:
A1
Abstract:
The present technique relates to a decoding device, a decoding method, and a program with which it is possible to decode images in parallel in units of tiles. In this technique, a parallel decoding unit decodes images that have been encoded according to, for example, an encoding scheme referred to as High Efficiency Video Coding (HEVC), said parallel decoding unit decoding said images in parallel in units of tiles which are employed in, for example, the encoding scheme referred to as HEVC. The present technique is applicable to, for example, a decoding device that receives an encoded stream encoded according to, for example, an encoding scheme referred to as HEVC, decodes said encoded stream, and generates images.
