Case: Alphanumeric Postal Code (
dcc_selection_type = 0x02, 0x12) If the dcc_selection_type is specified to be of type 0x02 or 0x12, the dcc_selection_id shall consist of a right justified eight alphanumeric and special 8-bit character postal code field of unspecified format padded on the left with space characters (0x20). The field may also contain separator characters, as necessary, to format the postal code according to country conventions. The separator characters may consist of any of the following special characters: comma (0x2C), dash (0x2D), period (0x2E), slash (0x2F) or space (0x30). The separator characters shall be considered to be “do not care” placeholders for purposes of logical comparison to a postal code stored within the DCCRR. The DCCRR shall compare that value to a stored representation of a postal code entered by the user from setup menus within the DCCRR to determine if there is a match. The alphanumeric and special characters permitted shall be any printing character within the character set from 0x20 through 0x7E inclusive. If a question mark (“?” or 0x3F) character appears in any of the eight character positions, that position shall be considered to be a wildcard which will permit a selection on any character within that position. For example “5B3-5Q?” would permit matches on 5B3-5Q0 through 5B3-5Q9 assuming the postal format convention was a numeric character in the rightmost character position. Similarly, “5B3-5?3” would permit matches on 5B3- 5A3 through 5B3-5Z3 assuming the postal format convention for the second from the rightmost character is alphabetic. Note that multiple postal codes may be specified within a single DCCT by means of the dcc_term_count loop. 55 ATSC A/65:2013 Program and System Information Protocol 7 August 2013 If the dcc_selection_type is defined to be of type 0x02, the term shall evaluate True if the alphanumeric postal code (with evaluated wild cards if any) given in the dcc_selection_id matches the stored alphanumeric postal code entered by the user and False otherwise. If the dcc_selection_type is defined to be of type 0x12, the term shall evaluate True if the alphanumeric postal code (with evaluated wild cards if any) given in the dcc_selection_id does not match the stored alphanumeric postal code entered by the user and False otherwise.
