Bitstream functions
\end_layout

\begin_layout Description
remaing_bits_in_bitstream(
\begin_inset space ~

) means the count of remaining bits after the current position in the bitstream.
 It is computed from the NumBytes value multiplied by 8 minus the count
 of bits already read by the bitstream parser.
\end_layout

\begin_layout Section
General Description
\end_layout

\begin_layout Standard
Each frame is split in 1 to 4 planes (Y, Cb, Cr, Alpha).
 In the case of the normal YCbCr colorspace the Y plane is coded first followed
 by the Cb and Cr planes, if an Alpha/transparency plane exists, it is coded
 last.
 In the case of the JPEG2000-RCT colorspace the lines are interleaved to
 improve caching efficiency since it is most likely that the RCT will immediatel
y be converted to RGB during decoding; the interleaved coding order is also
 Y,Cb,Cr,Alpha.
\end_layout

\begin_layout Standard
Samples within a plane are coded in raster scan order (left->right, top->bottom).
 Each sample is predicted by the median predictor from samples in the same
 plane and the difference is stored see
\begin_inset CommandInset ref
LatexCommand ref
reference "sub:Coding-of-the-sample-difference"

\end_inset

.
\end_layout

\begin_layout Subsection
Border
\end_layout

\begin_layout Standard
For the purpose of the predictior and context, samples above the coded slice
 are assumed to be 0; samples to the right of the coded slice are identical
 to the closest left sample; samples to the left of the coded slice are
 identical to the top right sample (if there is one), otherwise 0.

To encode scalar integers it would be possible to encode each bit separately
 and use the past bits as context.
 However that would mean 255 contexts per 8-bit symbol which is not only
 a waste of memory but also requires more past data to reach a reasonably
 good estimate of the probabilities.
 Alternatively assuming a Laplacian distribution and only dealing with its
 variance and mean (as in Huffman coding) would also be possible, however,
 for maximum flexibility and simplicity, the chosen method uses a single
 symbol to encode if a number is 0 and if not encodes the number using its
 exponent, mantissa and sign.
 The exact contexts used are best described by the following code, followed
 by some comments.

The alternative state transition table has been build using iterative minimizati
on of frame sizes and generally performs better than the default.
 To use it, the coder_type has to be set to 2 and the difference to the
 default has to be stored in the parameters.
 The reference implemenation of FFV1 in FFmpeg uses this table by default
 at the time of this writing when Range coding is used.

 The VLC code is split into 2 parts, the prefix stores the most significant

 number in the ESC case.
 The end of the bitstream (of the frame) is filled with 0-bits so that the

Run mode
\end_layout

\begin_layout Standard
Run mode is entered when the context is 0, and left as soon as a non-0 differenc
e is found, the level is identical to the predicted one, the run and the
 first different level is coded.
\end_layout

\begin_layout Paragraph
Run length coding
\end_layout

\begin_layout Standard
The run value is encoded in 2 parts, the prefix part stores the more significant
 part of the run as well as adjusting the run_index which determines the
 number of bits in the less significant part of the run.
 The 2nd part of the value stores the less significant part of the run as
 it is.
 The run_index is reset for each plane and slice to 0.

\begin_layout Paragraph
Level coding
\end_layout

\begin_layout Standard
Level coding is identical to the normal difference coding with the exception
 that the 0 value is removed as it cannot occur:
\end_layout

\begin_layout LyX-Code
if(diff>0) diff--;
\end_layout

\begin_layout LyX-Code
encode(diff);
\end_layout

\begin_layout Standard
Note, this is different from JPEG-LS, which doesn't use prediction in run
 mode and uses a different encoding and context model for the last difference
 On a small set of test samples the use of prediction slightly improved
 the compression rate.
