The TV station can lease a dedicated fiber connection and just use a fiber line
transmitter and receiver, or, in the event of multiple POV cameras (traffic cams) and
multiple fixed ENG Van connection points (city hall, federal building, arenas etc.),
IP connectivity can be leased from local private IP network operators based on
bandwidth requirement. With only 20Mbps bandwidth requirement per
origination point, ProHD is ideally suited for such applications.
An interesting 1394-to-IP Gateway for the ProHD format is now available:
Fig. 14. HD live backhaul over private IP network from remote
location, which may be Traffic-Cam or from ENG Van, using 1394-to-IP
gateways by QVidium. One potential problem with a 1394 link from the
ProHD camcorder is the limited physical length of a 1394 cable (max
about 15’ or 4.5m). A suitable application example is shooting a city
council meeting with the camcorder fixed on a tripod. An unsuitable
example is a “roving” camcorder where the 15’ of 1394 cable is not long
enough for freedom of movement. Another approach is to record
“roving” into the DR-HD100, and then play back “live” from the hard
disk unit into the gateway TX unit through the 1394 connection, or even
from a ProHD Edit laptop.
