CBS has tested HD MPEG-2 encoder/decoder products from NTT Electronics for HDTV electronic news gathering (ENG) use.
In the testing, CBS measured the microwave signals containing HD data from an ENG van parked up to 35 miles away from its receiving site on the Empire State Building. CBS experienced 100 percent success at HD data rate ranging from 18 to 28Mb/s, while it had to pass through the maze of buildings that is the Manhattan landscape. The tests, carried out in these most difficult of topographical and environmental conditions, demonstrated the feasibility of news gathering by ENG van where previously only satellite news-gathering (SNG) was possible.
The ENG van used in this testing was equipped with an NTT Electronics HE3000 MPEG-2 HDTV encoder, performing MPEG-2 data compression from HD-SDI to DVB-ASI. On the receiving end, the HD3000 MPEG-2 HDTV decoder was used to decode the received signals to HD-ASI for passing on to the video monitor.
