reresolve_time: The time, on the date given by reresolve_date, after which the receiver should try to re-resolve this<br />
CRID, using UTC as the time reference. This field shall be encoded as the number of 2-second periods since midnight.<br />

identifier_type: This field indicates the type of event identifier used in this <strong>DVB</strong> binary locator. This field shall be<br />
encoded according to table 32.<br />
See clause 11.1 for details on the semantics of this field.<br />
Table 32: Identifier type<br />
value Meaning<br />
'00' No event identifier field is present.<br />
'01' event identifier is an event_id.<br />
'10' event identifier is a TVA_id carried in EIT.<br />
'11' event identifier is a TVA_id carried in PES.<br />
scheduled_time_reliability: This field only has meaning when the value of identifier_type is '00', i.e. when no event<br />
identifier is provided and the receiver will need to use the scheduled time to control recording. When set, the<br />
early_start_window and late_end_window information shall be provided, which the receiver may use to improve the<br />
reliability of capture of the item of content (see clause 11.1). If the value of identifier_type is not '00' then this field shall<br />
be set to '0'.
