On2 vp6 Video Codec

1. ON2VP6

2. The VP6 codec was introduced in May
2003
 In November 2003, On2 announced that VP6 had been chosen as a
codec for China's Enhanced Versatile Disc
 In November 2003, On2 announced that the VP6 codec will be used in
products for broadcasting in the field, such as with BBC reporters
 Later incarnations of this codec are VP7 and VP8. With the Google
acquisition of On2, VP8 is licensed as open source.

3. On2vps
 lossy video compression format
 video codecs developed by On2 Technologies
 Commonly used by Adobe Flash, Flash Video, and JavaFX media files.

4. On2 VP6 Codec Info
 On2 boasts the VP6 video codec performs 40% better quality and 50%
better playback performance over the VP5 codec. On2 also claims that
the TrueMotion VP6 outperforms H.264, Windows Media 9 and Real
Networks 9 codecs in standardized testing.

5. VP6 ALGORITHM FUNDAMENTALS
 VP6 is a leading edge video compression algorithm having the following features:
 YUV 4:2:0 image format
 Macro-block (MB) based coding (MB is 16x16 luma plus two 8x8 chroma)
 ¼ pixel accuracy motion compensated prediction
 8x8 DCT transform
 64-level linear quantizer
 Prediction loop filter
 Frame variable quantization level
 Scaling on output after decode
 Two entropy coding strategies: Huffman & Binary Arithmetic (BoolCoder)
 Extensive context-based entropy coding strategy

6. FRAME TYPES
 Intra Frame
Intra, or I-frames, may be reconstructed from their compressed representation
with no reference to other frames in the sequence
 Inter Frame
Inter, prediction or P-frames, are encoded differentially with respect to a
previously encoded reference frame in the sequence.

7. Features of VP6
 VP6 is a high-quality,
 low bitrate video compression codec
 can be used as a plug-in within any video processing application that is
capable of utilizing third party codecs.
 The codec is free for personal/non-commercial use.

8. Features of VP6
VP6 can play back 1920x1080 HD material on a 2.5 GHz PC and 1280x720
material on a 1.5 GHz PC.
- Supports real-time encoding at full D1 resolution.
- Up to 40% image quality improvement over VP5.
- Up to 50% faster playback than VP5.
- Optimized to produce the best quality video available on high-resolution
material (640x480 and higher).
- Achieves any requested data rate by choosing automatically to adjust
quantization levels, adjust encoded frame dimensions, or drop frames
altogether.
