Reference Frame Management for Screen Content Video Coding Using Hash or Checksum Functions |
摘要 |
Techniques are provided for reference frame management for screen content video coding using hash or checksum functions. A video data stream including a plurality of frames is received, each frame including a plurality of pixels that define content within the frame. A plurality of hash code values associated with partitioned portions of a current frame are determined, where each hash code value is determined as an output value from a hash or checksum function based upon an input value comprising pixel values for a corresponding partition within the current frame. The current frame is compared with a plurality of reference frames based upon a comparison of the hash code values of the current frame with hash code values of the reference frames. A reference frame is selected as a candidate reference frame for coding the current frame.
