[This is preliminary documentation and subject to change.]
The amount and type of episode data that your application must provide varies depending on which of the reminder-setting methods described in Setting a Show Reminder you use, either calling the SetReminder method of ITVViewer, or by adding a reminder to the ScheduledItems collection of Television System Services (TSS).
If you are using the IScheduledItems::Add method to schedule a show reminder you must provide a fully specified show reference. For more information, see Show Reference Format.
If you are using ITVViewer::SetReminder to schedule a show reminder, your application must implement the IEPGEpisode interface and populate its property values with data about the episode for which you are setting a reminder. For more information, see IEPGEpisode.
