Main Spectral Data Encoding Trees

General Intro

The quantized values are encoded using a prefix free binary code. To make matters more complicated there are up to 16 encoding scheme per quantization precision (symbol set depends on precision, so different encoding schemes must be used for different precisions.). In many cases, the symbols are built from a group of two or four quantized values instead of just one quantized value. For groups of size two, the trees are shown as table, the first symbol choosing the row, the second value the column. For groups of size four, the tables are organized so that the first symbol chooses the row block, the second symbol the exact row, the third symbol the column block and the fourth symbol the column. I think about swapping second and third symbol, so be careful when coming back later!

Another catch is that some of the encoding schemes encoded the signed quantized values, while others encode only the absolute values of the quantized values. If only the absolute values are encoded in a symbol, each symbol is followed by one bit per absolute value that is not zero. If that bit is set, the value is negative.

The trees can be calculated as canonical huffman trees. Note that unsigned sorting (on two's complement numbers) is used, so negative numbers sort behind positive ones. The sort order for the grouped symbols is lexicographically by the single quantized numbers.

Examples

Interpreting a group-by-four block

Let's take a look at Tree 1A. The shortest symbol is (0,0,0,0), encoded with one bit, and gets assigned the code 0. The next shortest symbol has 4 bits, there is only one of them, and it is (-1,0,0,0). So this symbol gets the code 1000. Now, there are seven symbols with 5 bits. From top to bottom in the table, the symbols are

  • (0,-1,0,0)
  • (0,0,-1,0)
  • (0,0,0,-1)
  • (0,0,0,1)
  • (0,0,1,0)
  • (0,1,0,0)
  • (1,0,0,0)

Now for sorting these symbols lexicographically, rember that negative values go past positive ones (if we had -2,-1,0,1,2 the sorted order would be 0,1,2,-2,-1 instead). In this case, the sorted order ist

  • (0,0,0,1) → 10010
  • (0,0,0,-1) → 10011
  • (0,0,1,0) → 10100
  • (0,0,-1,0) → 10101
  • (0,1,0,0) → 10110
  • (0,-1,0,0) → 10111
  • (1,0,0,0) → 11000

Interpreting absolute value encoding

Now take a look at Tree 1H. In this coding scheme, the prefix free code is built from positive values only. Applying the algorithm to build the canonical code from the given lengths, one gets the following code assignment:

  • (0,0) → 0
  • (1,0) → 10
  • (0,1) → 110
  • (1,1) → 111

as the these codes are absolute value, they have to be interpreted as (0,0), (±1,0), (0,±1), (±1,±1) in fact, and the signs have to be specified afterwards. For each non-zero value from left to right, one bit being zero for positive and one for negative is appended to to the code, so you finally obtain

  • (0,0) → 0
  • (+1,0) → 100; (-1,0) → 101
  • (0,+1) → 1100; (0,-1) → 1101
  • (+1,+1) → 11100, (-1,+1) → 11110, (+1,-1) → 11101, (-1,-1) → 11111

===== Tree Sets ===== This table shows the mapping of tree set IDs, tree IDs and quantization precisions to the code tables defined above. If the table says n x Tree XX it means that n symbols of that tree (which might groups of 1, 2 or 4 quantized coefficients) are clustered together. Each cluster is preceeded by an "data present" bit. If that bit is zero, all coefficients of the whole cluster are zero, and no codes for the cluster are stored. If that bit is one that at least one non-zero entry is present and the codes for this cluster follow as in non-clustered mode. The tree choice can be limited to a restricted tree set. The IDs inside the restricted tree set are in the range 0..3 instead of 0..7, and printed as R0..R3 in the table. ==== Tree Set A====
