This equipment performs channel encoding and COFDM (coded orthogonal frequency-division multiplexing) modulation of a MPEG-2 transport stream for different bit rates. The system transmits compressed digital audio, digital video and other data in an MPEG transport stream, using COFDM or OFDM modulation. One single unit allows you to feed a TV transmitter with a fully modulated DVB-T channel. Easy installation, setup and control through the local display allows user friendly operations and instantaneous status monitoring.
Supporting single channel bandwidth 6/7/8 MHz
QPSK/16 QAM/64 QAM symbol mapping
No hierarchical transmission
Configurable convolution rates
The DVB-T Modulator is a cost-effective solution to distribute digital quality TV programs to the guest room TVs via existing coaxial network. With many cable providers now offering high-definition and digital programs, hotels do not have to remove or rework their whole cable network to offer guests such programs. Just by using a DVB-T modulator (explained in the diagram below), guests will still be able to enjoy clear and sharp images even if your hotel is using old analog model TVs. There are 2 models of modulator, a SD model and HD model.
