COMPLIANCE RECORDING

Introduction The latest optional feature for our single channel compliance recorders is an HD SDI input.

Previously, when it was needed to record HD feeds, broadcasters had to down-convert their HD transmissions to SD before plugging them into a TRACS² recorder. This is now a thing of the past.

With the HD option enabled the TRACS recorder can handle an HD SDI input by it self without using any external devices. Since TRACS must encode the inputs as capacity-efficient as possible, we downscale the HD input to SD before encoding it, to maintain compliant picture quality at the necessary low bitrates. Maintaining a high picture quality remains dependant on the heights of the bitrate however, so when you would like to keep an improved picture quality we advise to use higher bitrates when compared to SD recordings.

Features A TRACS² single channel recorder with the HD option enabled offers the following additional features:

SDI input can handle the following input formats: SD525, SD625 720p60, 720p50 1080i60, 1080i50 Burnt in LTC or NTP time code on the video input Custom setting for large (full D1) or small (CIF) video resolution encoding size.

Ability to record all 16 embedded audio channels out of the HD input Hardware playback of recorded content over SD-SDI and analog outputs (HD content is played back as SD or Composite) Capture downscaled HD video feeds in MPEG2, MPEG4 or H.264 (H.264 is only available when set to small resolution) Anamorphic (8_vid) WSS insertion into the down converted recordings

Capacity calculation The available capacity in days for each recorder is highly dependant on the recording settings (video bitrate, audio bitrate, VBI recording on/off and amount of audio channels). Since TRACS² recorders don’t record the HD vertical ancillary data there is no use for the VBI recording option.

The following table gives a few examples of possible settings and the remaining capacity in days.

All audio in this table is calculated as a bitrate of 32Kb/s, higher audio bitrates will decrease the capacity depending on the amount of audio channels you record. For an exact calculation of capacity in days for your desired setup, please contact Axon.
