Case: Demographic Category (
dcc_selection_type
 = 0x05, 0x06, 0x15, 0x16) 
If 
dcc_selection_type
is equal to 0x05, 0x06, 0x15, or 0x16, the 
dcc_selection_id
shall be specified to 
be a demographic selection bit field composed of one or more of the values described in Table 
6.18 logically ORed together. The DCCRR shall perform a comparison, based upon the 
dcc_selection_type
, of the value to a stored value within the DCCRR which had been entered by the 
user within setup menus to determine if there is a match.

If the selection is specified to be of type "One-or-More Members" (
dcc_selection_type
0x05), the 
received value within 
dcc_selection_id
shall be logically bitwise ANDed with the DCCRR’s stored 
value and then logically bitwise ANDed with a specification mask that indicates whether the 
viewer had entered values for each demographic selection category. If the result is non-zero, the 
term shall evaluate True. If the result is zero, the term shall evaluate False. This test permits 
selection based upon membership in at least one and possibly more demographic categories. In 
other words, the term evaluates True if any of the categories that had been selected and validated 
by the viewer correspond with membership in the demographic categories specified in the 
dcc_selection_id
field of the DCCT. 
If the selection is specified to be of type "One-or-More Non-members" (

0x15), 
the received value within 
dcc_selection_id
shall be logically bitwise ANDed with the 1's complement 
of the DCCRR’s stored value and then logically bitwise ANDed with a specification mask that 
indicates whether the viewer had entered values for each demographic selection category. If the 
result is non-zero, the term shall evaluate True. If the result is zero, the term shall evaluate False. 
This test permits selection based upon non-membership in at least one and possibly more 
demographic categories. In other words, the term evaluates True if any of the categories that had 
been selected and validated by the viewer correspond with non-membership in the DCC 
demographic categories specified in the

field of the DCCT.

If the selection is specified to be of type "All Members" (
dcc_selection_type
0x06), the received 
value within 
dcc_selection_id
shall be logically compared to the DCCRR’s stored value which has 
been logically bitwise ANDed with a specification mask that indicates whether the viewer had 
entered values for each demographic selection category. If the result of the comparison is that the 
values are equal, the term shall evaluate True, and shall evaluate False otherwise. This test permits 
selection based upon membership in all requested demographic categories. In other words, the 
term evaluates True if the categories that had been selected and validated by the viewer correspond 
with membership in all of the DCC demographic categories specified in the 
dcc_selection_id
field of 
the DCCT. 
If the selection is specified to be of type "All Non-members" (
dcc_selection_type
0x16), the 
received value within 
dcc_selection_id
shall be logically bitwise ANDed with the 1's complement of 
the DCCRR’s stored value and then logically bitwise ANDed with a specification mask that 
indicates whether the viewer had entered values for each demographic selection category. That 
result shall be compared to the DCCRR's stored value. If the result of the comparison is that the 
values are equal, the term shall evaluate True, and shall evaluate False otherwise. This test permits 
selection based upon non-membership in all requested demographic categories. In other words, 
the term evaluates True if the categories that had been selected and validated by the viewer 
correspond with non-membership in all of the DCC demographic categories specified in the 
dcc_selection_id
field of the DCCT.
