//        15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00

//       |  Len   |       Run       |     Level    |L | 1 |
//       +------------------------------------------------+
//       |                Offset                      | 0 |
//       +------------------------------------------------+
// If the table entry is a leaf entry then bit 0 set:
//    Len    = Number of bits overread  (0 to 7)  3 bits
//    Run    = RunLength of the Symbol  (0 to 63) 6 bits
//    Level  = Level of the Symbol      (0 to 31) 5 bits
//    L      = Last Value of the Symbol (0 or 1)  1 bit
//
// If the table entry is an internal node then bit 0 is clear:
//    Offset = Number of (16-bit) half words from the table
//             start to the next table node
//
// The table is accessed by successive lookup up on the
// next Step bits of the input bitstream until a leaf node
// is obtained. The Step sizes are supplied to the VLD macro.

// The VLC tables used for Intra and non inta coefficients in non Escape mode
// contains symbols with both Last=0 and Last=1.
// If a symbol is not found in the table it will be coded as 0xFFF
