Real Time Encoder with Digital TV Modulator
Part Number H-VQAM-SD
Input: 1x CVBS
Output: 1x QAM - 1x Program
Thor part number H-VQAM-SD is a basic real time hardware encoder combined with a digital TV channel modulator. This product was developed to reduce the cost of distributing basic video services over coax cable as a standard digital TV program. The system is built around a fast and reliable MPEG-2 encoder based on a high speed FPGA processor. Video inputs are first digitized by an ADC circuit, then encoded to MPEG-2 Format by the processor. The MPEG-2 transport stream is then modulated onto an RF carrier by a frequency agile modulator circuit. All standard digital TV frequencies from 35-960 MHz are supported, with all world QAM modulation standards. With full QAM anex J.83A, J.83B, and J.83C support, these systems can be used for both US QAM as well as European DVB-C.
All program settings are input via a simple front panel keypad and LCD monitor. This keeps the VQAM platform as inexpensive and purpose built as possible. VQAM is the most reliable and affordable modulator for digital TV in its class. Digital TV requires real time MPEG encoding, and therefore has been previously out of reach for consumer applications. VQAM breaks through this cost barrier, allowing AV Integrators and home theater enthusiasts to finally distribute live video throughout a home or business over existing coaxial cable as a live Digital TV channel. No special equipment is needed for the displays, and no inputs need to be changed to view the video. Simply change the channel to view the video. The program is available to all Televisions as a digital TV program complete with channel name, description, and custom virtual channel number.
