Abstract
Encoding video data includes accessing video information, and encoding macroblocks in an intra refresh (IR) region of a video frame of the video information with restricted quantization parameters (QPs) based on QPs of macroblocks within at least one of a non-IR region of the video frame and a co-located region of a neighboring video frame in a temporal domain.
Claims20
A method of encoding video data, comprising:
- accessing video information;
- and
- encoding macroblocks in an intra refresh (IR) region of a video frame of the video information with restricted quantization parameters (QPs) based on QPs of macroblocks within at least one of a non-IR region of the video frame, and a co-located region of a neighboring video frame in a temporal domain.
An apparatus for encoding video data, the apparatus comprising a video encoder logic structured to:
- access video information;
- and
- encode instantaneous decoder refresh (IDR) type macroblocks in an intra refresh (IR) region of a video frame with restricted quantization parameters (QPs) based on QPs of macroblocks within at least one of a non-IR region of the video frame, and a co-located region of a neighboring video frame in a temporal domain.
A non-transitory computer readable medium comprising executable instructions that when executed cause an integrated circuit (IC) fabrication system to fabricate one or more ICs that comprise:
- a video encoder logic structured to:
- access video information;
- and
- encode instantaneous decoder refresh (IDR) type macroblocks in an intra refresh (IR) region of a video frame with restricted quantization parameters (QPs) based on QPs of macroblocks within at least one of a non-IR region of the video frame, and a co-located region of a neighboring video frame in a temporal domain.
