How will the transition to High Definition affect video duplicating?
First, all PSAs that are going to be tracked via Nielsen, must be encoded with the SpotTrac code which replaces the previous coding system. SPOTTRAC encoding can also be done with SD (Standard Def) formats as well. One of the best features of using Spottrac encoder is the audio is watermarked. This allows PSAs on DVD, H.264, .WMV files to be tracked through the audio channel. Its not just for HD. In order to provide SPOTTRAC encoding for HD formats an HD SPOTTRAC encoder is required.
The Nielsen SpotTrac encoding system can be used with either SD (Standard Def) or HD (High Definition) formats. Since many stations are still broadcasting in SD, it is best to send tapes to stations with both the analog and SpoTTrac codes, because some stations are converting sooner than others. If the tape they receive does not have the HDTV code, and they are broadcasting in HD, they cannot be tracked by Nielsen. One of the best features of using SpotTrac encoder is the audio is watermarked. This allows PSAs on DVD, H.264, .WMV files to be tracked through the audio channel. Its not just for HD.
