CEA-761-B defines minimum specifications for a one-way data path utilizing an 8 VSB trellis or a 16 VSB remodulator
in compliance with ATSC Standard A/53, Annex D, and also defines on-screen display (OSD) capabilities.
The network had room for expansion and the cost of access would be a modem, headend remodulator, and the cost of implementing LANs in the appropriate locations, a necessity in any case.
provided a rapidly modified M8023 modem and HR8023 headend remodulator to accommodate the need for off-channel transmission of medical images.
3 minimum standard transmission coverage area of 3600 meters to 4500 meters, while still using a headend remodulator to minimize interference with adjacent services.
The A-B broadband system consists of a Data Gateway connecting the A-B Data Highway to the broadband network; the head-end remodulator
for controlling on-line network operations; a Network Interface Controller (NIC) for interfacing intelligent, high-speed devices to the LAN; and a terminal communication server to interconnect up to eight nonintelligent RS-232 devices to the broadband system.
The Consumer Electronics Association (CEA[R])'s Digital Television (DTV) Interface Subcommittee published CEA-761-B, DTV Remodulator
Specification with Enhanced OSD Capability, and CEA-CEB5-B, Recommended Practice for DTV Receiver "Monitor" Mode Capability.
K Tech Telecom has introduced an 8-VSB Remodulator for an HDTV REMOD application.
The channel multipath interference is removed by the remodulator and a fresh copy of the 8-VSB signal is retransmitted by the repeater transmitter at the HDTV REMOD site.
The Ethermodem product family -- consisting of the Ethermodem IV Transceiver, the Ethermodem Headend Remodulator
and the Ethermodem Bridge -- provides Ethernet networking over standard CATV cabling, known as broadband.
ProTelevision Technologies supplies modulators and remodulators
for DVB-T (Digital Video Broadcasting - Terrestrial).
Allen-Bradley is now developing specialized components such as modems, head-end remodulators
and switch gearboxes, gateway modules, and terminal-communications servers.
