Frames# 5, 6 and 7 of the Original Sequence Frame# 5 of the decoded frame, Successfully decoded lost Frame # 6. Frame# 6 was reconstructed by Frame copy. Frame #7 is degraded. Temporal Replacement - Frame Copy
"Inter" temporal prediction – block based motion estimation and compensation 1. Multiple reference pictures 2. Reference P pictures 3. Arbitrary referencing order 4. Variable block sizes for motion compensation Seven block sizes: 16x16, 16x8, 8x16, 8x8, 8x4, 4x8 & 4x4 5. 1/4-sample luma interpolation (1/4 or 1/8th-sample chroma interpolation) 6. Weighted prediction 7. Frame or Field based motion estimation for interlaced scanned video
Frames# 5, 6 and 7 of the Original Sequence Frame# 5 of the decoded frame, Successfully decoded lost Frame # 6. Frame# 6 was reconstructed by Motion Copy algorithm. Frame #7 is degraded. ,[object Object]
