HDMI To HD H.264 Encoder built-in Multiplexer,
DVB-T Modulatorand RF Up-Conversion
The HDMI2OFDM is a Cost-effective,high definition MPEG4 AVC broadcast distribution encoder with OFDM modulation and RF up- conversion built in.It is equipped with up to 4 channels of HDMI inputs, 1 ASI input, and output with 2 ASI ports, 1 UDP IP port, and 1 RF port.
The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna,etc. Its output signal is to be received by a DVB-T standard TV, DVB-T STB.
Using the latest technology, DIBSYS has developed a direct conversion process that allows the Universal Modulator to provide an RF output from 30 MHz to 900 MHz with superior shoulders and MER.
- Up to 2 HD Encoding module per chassis, each module with two channels H.264 encoding
- MPEG-TS Over IP and ASI output built-in multiplexing with 1x ASI input
- Advanced MPEG-4 AVC HP@L4 video compression
- ASIC technologies which offer broadcast video quality, generally video bitrate advised 720p about 2mbps,1080p about 6mbps for lowest bitrates
- HDMI 1.3a interface, Auto detect the HDMI input of resolutions
- Resolution: 1080p,1080i,720p @50/60Hz
- The direct conversion process offers superior performance with Shoulder Levels≤-55 dBc and MER ≥42dB;Bandwidth 6,7,8Mhz
- RF frequency:30-900MHz,1khz step
- Selectable 1 or 2* DVB-T Modulation out (2 carriers combined), double output bandwidth
- The output level is adjustable from -30~-10dbm (81~97dbμV) in 0.1db step.
- High performance standard of Encoder/Modulator with superior RF specifications,stream and processing functionality
- PSI/SI generate and NIT insertion,LCN modify
- PID filter,Pass and remapping
- High quality video and audio outputs
- Management via WEB,Local front panel with LCD
