Accurate recording

The Accurate Recording (AR) function enables digital video recorders ( Personal Video Recorder , PVR) to record the exact broadcast of digital TV programs without unnecessary lead times and follow-up times. The recording starts automatically at the beginning of the program and ends a few seconds after the program has ended. The PVR evaluates the data that are transmitted in the table “ EIT present / following” (EIT p / f). The event_idor (if available) the is TVA_idused to control the broadcast-specific recording . By using these so-called "event identifiers" ( event codes), the recording of the exact broadcast is possible regardless of the often imprecise time information in the "EIT Schedule" table. The AR function replaces the Video Programming System (VPS) / Program Delivery Control (PDC) known from analog television and is also known as "Perfect Recording" or "Signal-supported recording" or "Automatic time control". Currently, Accurate Recording is mainly supported in German-speaking countries by the public broadcasters ARD, ZDF, ORF and SRG.
