Abstract
The present invention relates to an apparatus for processing a video, comprising: a video central processing unit which communicates with a host, receives a bitstream and parses header information; and a free scan module which generates free scan information by a free scan of a video bitstream inputted from the host according to the control of the video central processing unit, wherein the video central processing unit rearranges the bitstream on the basis of the header information and the free scan information and performs task scheduling so as to perform parallel decoding of the rearranged bitstream by a predetermined unit.
Claims19
A device for processing videos, comprising:
- a video central processing unit which is able to communicate with a host and is provided to receive a bitstream and parse header information;
- and
- a prescan module which is provided to generate prescan information by prescanning the bitstream from the host in according to controlling of the video central processing unit,
- wherein the video central processing unit realigning the bitstream based on the prescan information and the header information, and performing a task scheduling to decode in parallel the realigned bitstream in predetermined unit.
A method for processing videos, comprising:
- a step wherein header information is parsed by receiving a bitstream while communicating with a host;
- a step wherein prescan information is generated by prescanning a video bitstream inputted from the host;
- and
- a step wherein the video bitstream is realigned based on the prescan information and the header information, and a task scheduling is carried out to decode in parallel the realigned bitstream per unit.
