Autores ResumoTe I evi s i o n995 was an exciting year as new 1 technologies became commercially available.The year started with the launch of not one but two new television networks, United Paramount Network (UPN), and The Warner Brothers Network (The WB).Station affiliations became a commodity as six networks vied for market share.Two of the major television networks changed owners.CapCitiesl ABC merged with The Walt Disney Co. and CBS was acquired by Westinghouse.Meanwhile, NBC started project GEnesis, a complete replacement of its current network origination facilities and an upgrade of its network distribution facilities.The technical facility will encompass approximately 32,000 sq.ft. and be built on a component digital platform.Serial component digital technology has finally become cost-effective, deliverable, and system-friendly.The impending doom of the VTR seemed to diminish as digital Betacam started to dominate the market of main stream television production and postproduction.D-5 and DVCPRO, introduced by Matsushita Electric Industrial Co. and marketed through Panasonic, were the new tape formats for 1995.The D-5 format is a 1/2-in.full-bit component digital VTR conforming to SMPTE 259M.It has a 10-bit, 13.5-MHz sampling frequency, a data rate of 300 Mbitdsec, and is compatible with both the D-3 format and EDTV-11.The DVCPRO format uses a 1/4-in.tape and records a component digital signal compressed at a ratio of 1.5: 1.The system includes a camcorder, studio VTR, and field recorder.Video server technology matured to deliverable product.Stations across the country installed BTS, Dynatech, Hewlett-Packard, or Tektronix servers for recording and playback of material to air.Server technology was no longer a story of video storage but rather of data storage.IBM, Ampex, and Panasonic marketed data recorders for use with library systems as well as standalone devices.Ikegami demonstrated a 4:2:2 dockable disk recorder featuring 13.5-MHz, 8-bit sampling, and 15 to 20-
