59. Each data word is one I-component as seen in
Table 32
.
60. Each I data is a signed two's-complement 24-bit sample with signed extended into 32-bit.
Thus, each component is an integer ranging from -8388608 to +8388607 (or ±2
23
).

Examples conversion:
Given the big-endian bytes 0x0018FFFE, then I

= 0x18FFFFE.
Given the big-endian bytes 0xFF800034, then I

State and Event Indicators and the associated Enable bits shall be positions as indicated
in
Table 34
.
61. For each Indicator bit in the State and Event Indicators field, there is a corresponding
Enable bit at the same position in the Enables field.
62. When an Enable bit is set to 1, the corresponding indicator shall
function as shown in
Table 34
. Otherwise, the corresponding indicator shall
not be considered valid.
63. Unused bits in the Enables field and the Indicators field shall be set to 0.
64. The E field shall be set to 0 to specify the Associated Context Packet Count field as
undefined.
65. The Associated Context Packet Count field is unused and shall be set to 0.
