深圳市鑫成通電子有限公司供應(yīng)DTE--27832121Designed to meet the most demanding requirements of today’s Digital Terrestrial Television Broadcast Marketsprocess.
General
Designed to meet the most demanding requirements of today’s Digital Terrestrial Television Broadcast Markets, A key factor in the products success is the quality of the coding and modulation process. The modular design makes the unit highly flexible and the modulator is easily adaptable to provide the exact features required in a specific application.
This means that you will only have to pay for the functional features that you need. Retrofitting of features is easy by uploading new firmware and software from a standard PC.
FEATURES
Full hierarchical mode support
SFN and MFN support
Near seamless switching between inputs
Superior MER performance
Outstanding linear and non-linear digital pre-correction
Web browser and SNMP remote control
Player Functionality
CHANNEL SELECT
Tunable to any UHF/VHF or cable channel.
LEVEL
Lets you adjust the RF level of the output for receiver stressing.
PLAY LIST RECALL
Will recall to the unit display and list of programs stored in the unit and on the DVD drive.
PLAY
Starts the selected program. The vacuum fluorescent display provides the program name, duration, channel, RF
level, and percent of content played.
RECORD
Activates the unit's ability to capture a video data stream.
