Contemporary Research QMOD-SDI HDTV SDI QAM Modulator / Encoder

Contemporary Research QMOD-SDI HD-SDI Modulator

CR QMOD™ technology is opening the doors to new HDTV applications. The QMOD™-SDI HD SDI enables cost-effective distribution of HD-SDI, SD-SDI, digital signage, HD subscriber sources, and EAS emergency AV using existing broadband coax cabling in sports, retail and entertainment facilities, corporate offices, colleges, schools and worship centers.

• Create your own on-site HDTV broadband distribution system using HD-SDI, Component, and NTSC video sources
• Distribute digital signage, satellite, cable, and media as HD digital cable channels over existing broadband wiring
• View HD sources at any destination using HDTV displays or tuners

Features

• Accepts digital HD-SDI (1080i/720p) and SD-SDI (480i)
• Auto-senses SDI resolution, changes QMOD resolution to match
• Inputs analog HD Component, S-Video and Composite video
• Presents 480p/480i video as full-screen image (rather than a small image in a 720p window)
• Switches between SDI, Component, and video inputs with audio follow
• Responds to GPI inputs to switch to EAS composite video and audio
• Employs pro-grade HD encoding by NTT that minimizes artifacts for motion video and signage “tickers”
• Merges audio with video from embedded SDI, analog stereo, digital optical and coax inputs
• Creates a high-definition 720p/1080i MPEG-2 stream for broadcast
• Delivers a fully agile QAM 64/256 digital cable channel 2-135
• Amplifies for distribution over an on-site broadband cable system with adjustable output level to 29 dBmV, compatible with all cable format broadband systems
• Sets up with front-panel buttons and easy to use menus, including inputs, encoding, channel, and RF options
• Powers up in less than 4 seconds, no OS overhead
• Integrates with RS-232 control and feedback with simple ASCII commands
• Saves power and rack space using efficient design, fan-free cooling, and compact enclosure
• Includes compact switching power supply
• Mounts in optional 1RU single (RK1) or dual (RK2) 19” rack kits
• Meets RoHS safety and California energy standards.

Integration

• Connect SDI, Component, S-Video or Video (QMOD-SDI can swtich between SDI, Component, and Composite)
• Connect audio to digital optical, coax, or stereo audio inputs
• Select inputs, channel, resolution, and RF output parameters from front-panel menus
