1.2 DTV701 Overview
The DTV701 Broadcast Digital Television Processor (see Figure 1.1) receives
VHF/UHF broadcast HDTV signals and provides an output ASI stream for
connection to a cable system QAM modulator. It will accept a broadcast ATSC
8VSB signal on the tuner input and produces an ASI MPEG Transport Stream
output suitable for connection to a QAM modulator (64QAM or 256QAM).
Programs may be remapped or selected for removal from the output stream.
Physical
Description The DTV701 is housed in a standard, rack-mountable chassis. Its front panel
provides a user interface through an LCD, eight LEDs, and six push buttons
(see section 3.3 DTV701 Controls and Indicators on page 24). The rear panel
holds the ports that allow connection to power, incoming signal, and peripheral
devices.
Figure 1.1 DTV701 Broadcast Digital Television Processor
Features Your DTV701 has the following features:
• One ATSC 8VSB tuner input (F connector)
• Two duplicate ASI MPEG Transport Stream outputs (BNC connectors)
• Time re-stamping of PCR, PTS, and DTS information.
• User selection of input programs to be included in the output stream.
• One Ethernet TCP/IP control interface (RJ-45 connector)
• One asynchronous data input/output (DB-9 connector)
