TANDBERG Television will demonstrate the newest features of its encoders, multiplexers and new professional receivers at NAB in its booth #SU4210. New features include support of SMPTE 2016-1-2007, "Format for Active Format Description and Bar Data", for the E5700 series encoders and PSIP carouselling for the MX5620 multiplexer. Additionally, NAB marks the launch of the RX8320 ATSC Broadcast Receiver, designed specifically to ease the digital transition for broadcasters and service providers alike.

Using the new Active Format Description (AFD) feature of the E5700 series encoders, broadcasters can transmit the AFD signal with the high definition picture to signal downstream devices what to do when they convert an HD digital picture into an analog picture. It can signal that the video has been created in a manner that protects the 4x3 center of the picture (thereby requesting the downstream device to do a 4x3 center cut during downconversion) or it can signal that the 16x9 aspect ratio should be maintained and that the downconverted picture should be letterboxed instead.

Being able to deliver the AFD signal to downstream receivers capable of reading it and acting accordingly (such as the newly introduced RX8320 ATSC Broadcast Receiver from TANDBERG Television) is of paramount importance to broadcasters wanting to maintain control of the look and feel of their signal to viewers after the digital transition.

The PSIP carouselling feature provides a backup system for broadcasters; if the external PSIP generator fails, the mux will continue to spool (carousel) and send PSIP information to maintain a compliant ATSC signal until the PSIP generator has been restored. This is particularly critical to broadcasters, who must maintain compliance with the PSIP data for downstream receive devices to function properly.
