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'.
