The ProHD Report

Operational Flexibility = Direct-to-Edit / Direct-to-Air

The ProHD ENG system provides exceptional flexibility in work flow, in the ENG Van and in the TV station news operation. A key sub-system is the DR-HD100, a portable hard disk recorder which attaches to the ProHD camcorder and records up to 6 hours of full bandwidth 1280x720p60. The DR-HD100 is a rugged, shock-proofed field recorder accepting the 1394 MPEG-2 TS 20Mbps signal directly from the ProHD camcorder, recording to hard disk concurrently while recording to the built-in HDV tape cassette for acquisition archival purposes.

Fig. 8. The DTE (Direct-to-Edit) ProHD hard disk recorder can be attached on top of the camcorder or on the back side of the battery, recording up to 6 hours of live compressed material direct to disk at.

The DR-HD100 can be connected via 1394 to a laptop or to a workstation with direct access to the HD material for editing, without the need to transfer to the local disk array before editing. Thus the name “Direct-to-Edit” or DTE. NOTE:

JVC’s Direct-to-Air work flow supports live interviews through wired coax and wireless microwave to the ENG Van, then backhaul microwave (or satellite) to the TV station studio for immediate on-air. Through the simplicity of the DR-HD100 and an edit-capable lap top in the ENG Van, minimally delayed edited “live coverage” can be easily accomplished through the Direct-to-Edit capabilities the ProHD ENG system. One advantage in hard disk recorders is the near instant random access to any material on the disk.

Play from NLE Direct-to-Air. The GV Canopus Edius ProHD editor can play direct-to-air from the NLE, enabling extremely fast turn-around of clips needing editing before airplay and avoiding the need to first record or store the clip. The Edius ProHD application may run on a laptop in the ENG Van or on a desktop in a news edit bay.
