Snow Video Codec Specification Draft 20080110 |
||||
============================================= |
||||
|
||||
Introduction: |
||||
============= |
||||
This specification describes the Snow bitstream syntax and semantics as |
||||
well as the formal Snow decoding process. |
||||
|
||||
The decoding process is described precisely and any compliant decoder |
||||
MUST produce the exact same output for a spec-conformant Snow stream. |
||||
For encoding, though, any process which generates a stream compliant to |
||||
the syntactical and semantic requirements and which is decodable by |
||||
the process described in this spec shall be considered a conformant |
||||
Snow encoder. |
||||
|
||||
Definitions: |
||||
============ |
||||
|
||||
MUST the specific part must be done to conform to this standard |
||||
SHOULD it is recommended to be done that way, but not strictly required |

this SHOULD be 1 unless it turns out to be covered by a valid patent |
||||
|
||||
htaps |
||||
number of half pel interpolation filter taps, MUST be even, >0 and <10 |
||||
|
||||
hcoeff |
||||
half pel interpolation filter coefficients, hcoeff[0] are the 2 middle |
||||
coefficients [1] are the next outer ones and so on, resulting in a filter |
||||
like: ...eff[2], hcoeff[1], hcoeff[0], hcoeff[0], hcoeff[1], hcoeff[2] ... |
||||
the sign of the coefficients is not explicitly stored but alternates |
||||
after each coeff and coeff[0] is positive, so ...,+,-,+,-,+,+,-,+,-,+,... |
||||
hcoeff[0] is not explicitly stored but found by subtracting the sum |
||||
of all stored coefficients with signs from 32 |
||||
hcoeff[0]= 32 - hcoeff[1] - hcoeff[2] - ... |
||||
a good choice for hcoeff and htaps is |
||||
htaps= 6 |
||||
hcoeff={40,-10,2} |
||||
an alternative which requires more computations at both encoder and |
||||
decoder side and may or may not be better is |
||||
htaps= 8 |
||||
hcoeff={42,-14,6,-2} |
||||
|
||||
|
||||
ref_frames |
||||

Binary Range Coder: |

------------------- |
||||
The implemented range coder is an adapted version based upon "Range encoding: |
||||
an algorithm for removing redundancy from a digitised message." by G. N. N. |
||||
Martin. |
||||
The symbols encoded by the Snow range coder are bits (0|1). The |
||||
associated probabilities are not fix but change depending on the symbol mix |
||||
seen so far. |

Range Coding of integers: |
||||
------------------------- |
||||
FIXME |
||||
|
||||
|
||||
Neighboring Blocks: |
||||
=================== |
||||
left and top are set to the respective blocks unless they are outside of |
||||
the image in which case they are set to the Null block |
||||
|
||||
top-left is set to the top left block unless it is outside of the image in |
||||
which case it is set to the left block |
||||
|
||||
if this block has no larger parent block or it is at the left side of its |
||||
parent block and the top right block is not outside of the image then the |
||||
top right block is used for top-right else the top-left block is used |
||||
|
||||
Null block |
||||
y,cb,cr are 128 |
||||
level, ref, mx and my are 0 |
||||
|
||||
|
||||
Motion Vector Prediction: |
||||
========================= |
||||
1. the motion vectors of all the neighboring blocks are scaled to |
||||
compensate for the difference of reference frames |
||||
|
||||
scaled_mv= (mv * (256 * (current_reference+1) / (mv.reference+1)) + 128)>>8 |
||||
|
||||
2. the median of the scaled left, top and top-right vectors is used as |
||||
motion vector prediction |
||||
|
||||
3. the used motion vector is the sum of the predictor and |
||||
(mvx_diff, mvy_diff)*mv_scale |
||||
|
||||
|
||||
Intra DC Predicton: |
||||
====================== |
||||
the luma and chroma values of the left block are used as predictors |
||||
|
||||
the used luma and chroma is the sum of the predictor and y_diff, cb_diff, cr_diff |
||||
to reverse this in the decoder apply the following: |
||||
block[y][x].dc[0] = block[y][x-1].dc[0] + y_diff; |
||||
block[y][x].dc[1] = block[y][x-1].dc[1] + cb_diff; |
||||
block[y][x].dc[2] = block[y][x-1].dc[2] + cr_diff; |
||||
block[*][-1].dc[*]= 128; |

|
||||
|
||||
Motion Compensation: |
||||
==================== |
||||
|
||||
Halfpel interpolation: |
||||
---------------------- |
||||
halfpel interpolation is done by convolution with the halfpel filter stored |
||||
in the header: |
||||
|
||||
horizontal halfpel samples are found by |
||||
H1[y][x] = hcoeff[0]*(F[y][x ] + F[y][x+1]) |
||||
+ hcoeff[1]*(F[y][x-1] + F[y][x+2]) |
||||
+ hcoeff[2]*(F[y][x-2] + F[y][x+3]) |
||||
+ ... |
||||
h1[y][x] = (H1[y][x] + 32)>>6; |
||||
|
||||
vertical halfpel samples are found by |
||||
H2[y][x] = hcoeff[0]*(F[y ][x] + F[y+1][x]) |
||||
+ hcoeff[1]*(F[y-1][x] + F[y+2][x]) |
||||
+ ... |
||||
h2[y][x] = (H2[y][x] + 32)>>6; |
||||
|
||||
vertical+horizontal halfpel samples are found by |
||||
H3[y][x] = hcoeff[0]*(H2[y][x ] + H2[y][x+1]) |
||||
+ hcoeff[1]*(H2[y][x-1] + H2[y][x+2]) |
||||
+ ... |
||||
H3[y][x] = hcoeff[0]*(H1[y ][x] + H1[y+1][x]) |
||||
+ hcoeff[1]*(H1[y+1][x] + H1[y+2][x]) |
||||
+ ... |

if diag_mc is set then points which lie on a line between 2 vertically, |

horiziontally or diagonally adjacent halfpel points shall be interpolated |
||||
linearls with rounding to nearest and halfway values rounded up. |

points which lie on 2 diagonals at the same time should only use the one |
||||
diagonal not containing the fullpel point |

Each sample in the LL0 subband is predicted by the median of the left, top and |
||||
left+top-topleft samples, samples outside the subband shall be considered to |
||||
be 0. To reverse this prediction in the decoder apply the following. |
||||
for(y=0; y<height; y++){ |
||||
for(x=0; x<width; x++){ |
||||
sample[y][x] += median(sample[y-1][x], |
||||
sample[y][x-1], |
||||
sample[y-1][x]+sample[y][x-1]-sample[y-1][x-1]); |
||||
} |
||||
} |
||||
sample[-1][*]=sample[*][-1]= 0; |
||||
width,height here are the width and height of the LL0 subband not of the final |
||||
video |

Wavelet Transform: |
||||
================== |
||||
|
||||
Snow supports 2 wavelet transforms, the symmetric biorthogonal 5/3 integer |
||||
transform and a integer approximation of the symmetric biorthogonal 9/7 |
||||
daubechies wavelet. |
||||
|
||||
2D IDWT (inverse discrete wavelet transform) |
||||
-------------------------------------------- |
||||
The 2D IDWT applies a 2D filter recursively, each time combining the |
||||
4 lowest frequency subbands into a single subband until only 1 subband |
||||
remains. |
||||
The 2D filter is done by first applying a 1D filter in the vertical direction |
||||
and then applying it in the horizontal one. |
||||
--------------- --------------- --------------- --------------- |
||||
|LL0|HL0| | | | | | | | | | | | |

||||
| | | | | | | | | | | | |
||||
--------------- --------------- --------------- --------------- |
||||
|
||||
|
||||
1D Filter: |
||||
---------- |
||||
1. interleave the samples of the low and high frequency subbands like |
||||
s={L0, H0, L1, H1, L2, H2, L3, H3, ... } |
||||
note, this can end with a L or a H, the number of elements shall be w |
||||
s[-1] shall be considered equivalent to s[1 ] |
||||
s[w ] shall be considered equivalent to s[w-2] |
||||
|
||||
2. perform the lifting steps in order as described below |
||||
|
||||
5/3 Integer filter: |
||||
1. s[i] -= (s[i-1] + s[i+1] + 2)>>2; for all even i < w |
||||
2. s[i] += (s[i-1] + s[i+1] )>>1; for all odd i < w |

|

Snow's 9/7 Integer filter: |
||||
1. s[i] -= (3*(s[i-1] + s[i+1]) + 4)>>3; for all even i < w |
||||
2. s[i] -= s[i-1] + s[i+1] ; for all odd i < w |
||||
3. s[i] += ( s[i-1] + s[i+1] + 4*s[i] + 8)>>4; for all even i < w |
||||
4. s[i] += (3*(s[i-1] + s[i+1]) )>>1; for all odd i < w |

optimization tips: |
||||
following are exactly identical |
||||
(3a)>>1 == a + (a>>1) |
||||
(a + 4b + 8)>>4 == ((a>>2) + b + 2)>>2 |
||||
|
||||
16bit implementation note: |
||||
The IDWT can be implemented with 16bits, but this requires some care to |
||||
prevent overflows, the following list, lists the minimum number of bits needed |
||||
for some terms |
||||
1. lifting step |
||||
A= s[i-1] + s[i+1] 16bit |
||||
3*A + 4 18bit |
||||
A + (A>>1) + 2 17bit |
||||
|
||||
3. lifting step |
||||
s[i-1] + s[i+1] 17bit |
||||
|
||||
4. lifiting step |
||||
3*(s[i-1] + s[i+1]) 17bit |
||||
|
||||
|
||||
TODO: |
||||
===== |
||||
Important: |
||||
finetune initial contexts |
||||
flip wavelet? |
||||
try to use the wavelet transformed predicted image (motion compensated image) as context for coding the residual coefficients |
||||
try the MV length as context for coding the residual coefficients |
||||
use extradata for stuff which is in the keyframes now? |
||||
the MV median predictor is patented IIRC |
||||
implement per picture halfpel interpolation |
||||
try different range coder state transition tables for different contexts |
||||
|
||||
Not Important: |
||||
compare the 6 tap and 8 tap hpel filters (psnr/bitrate and subjective quality) |
||||
spatial_scalability b vs u (!= 0 breaks syntax anyway so we can add a u later) |
