AMAZING TECHNOLOGY!

Many television stations currently send IFB to talent in the field during ENG situations via the PRO audio channel in their NTSC TV signal. Some stations have switched to wireless/cell phones or 2-way radio but those operations that rely on the use of the PRO channel for cueing will face a problem after the analog cut-off on February 17, 2009 because there will be no more NTSC and hence no more PRO channel. Modulation Sciences, Inc. (Somerset,N.J.) has announced that it has developed technology that will allow stations to send IFB via the ATSC Transport Stream (TS) in their DTV signal.
This technology places MPEG-1 encoded audio into the TS which must be assigned its own PID. The number of IFB channels available is limited only by the bandwidth the station is able to allocate for this purpose. Each MPEG-1, layer 2 data stream requires 96 kbps. Each audio channel takes 48 kbps but they must be assigned in pairs. Most MPEG encoders already have the ability to generate the MPEG-1 layer 2 data streams. Stations should check with their encoder manufacturer for guidance.

Once the IFB audio is in the station's TS, a receiver located in the ENG vehicle is tuned to the DTV channel, the MPEG-1data stream is extracted and IFB or cue audio is output to the talent. This operates much like a digital version of analog PRO receivers in use today. The receiver includes LG Electronics' 6th generation DTV receiver chip set which provides significantly improved ATSC over-the-air reception.

It was generally believed previously that there was too much latency in the ATSC DTV signal to use it for an effective IFB system. However, Modulation Sciences has indicated that it recently measured an end-to-end latency with this technology at just less than 100 mSec. The product is called "DIGITAL PROceiver"
