Digital DCR vs DTVR
DCR (Digital Content Ratings) vs. DTVR (Digital TV Ratings)
| Scenario/Feature | DTVR | DCR | Notes |
|---|---|---|---|
| SDK Measurement Events | ID3 tags read from video stream - SDK determines channel change by PC/FD CID change and calculates crediting time by observing the offset values | All events must be passed from player to SDK (playhead, stop, end) - new loadMetadata call alerts SDK to channel/content change, each playhead "tick" accumulates one second to crediting | - |
| Ping Differences | *TSV (Time Shift View) - sent on first ID3 tag received by SDK *I (Impression) - sent on first ID3 tag received by SDK *V (View) - sent after the first minute of crediting *D (Duration) - sent periodically to record credit *Trans (Translator) - sent once per minute of viewing |
*V (View) - sent after the first playhead event has been received by SDK *D (Duration) - sent periodically to record credit |
