T.0X ENCODER TWIN comp. COFDM / QAM + feeder Televes
A modulator is a device that transforms an audio/video signal from a source into a digital television channel (Multiplex).
A modulator is a device that transforms an audio/video signal from a source into a digital television channel (Multiplex).
The contents of a Multiplex produced by the Twin Encoder Modulator (ref.566011) consist in two services, since it has two composite video analogue inputs (CVBS), which can be generated by multiple devices, such as cameras, computers, etc. Video can be configured both in MPEG-2 and H-264 (MPEG-4) formats.
The main parameters of the generated signal, such as LNC availability or output modulation mode, can be edited.
The device can be configured either via the web interface embedded in the module or by means of the universal programmer.
Highlights
- Two physical inputs for composite audio and video.
- High output power in RF without the need for extra amplification.
- Configurable via web interface.
- Device monitoring and signal status LEDs.
- Perfect image and audio synchronization.
Features
- Two physical inputs for CVBS video and for audio (L,R)
- MPEG-2 or MPEG-4 (H.264) video output format
- Supports auto-scan for input resolution
- COFDM or QAM output
- Excellent quality of the generated signal MER>40dB
- Rack or individual mount
- Combiner included (loop input)
