51// If the table entry is a leaf entry then bit 0 set:
52//    Len    = Number of bits overread  (0 to 7)  3 bits
53//    Run    = RunLength of the Symbol  (0 to 63) 6 bits
54//    Level  = Level of the Symbol      (0 to 31) 5 bits
55//    L      = Last Value of the Symbol (0 or 1)  1 bit
56//
57// If the table entry is an internal node then bit 0 is clear:
58//    Offset = Number of (16-bit) half words from the table
59//             start to the next table node
60//
61// The table is accessed by successive lookup up on the
62// next Step bits of the input bitstream until a leaf node
63// is obtained. The Step sizes are supplied to the VLD macro.
64
65// The VLC tables used for Intra and non inta coefficients in non Escape mode
66// contains symbols with both Last=0 and Last=1.
67// If a symbol is not found in the table it will be coded as 0xFFF
