The ProHD Report

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:

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.
