Thor H-VQAMSD 1 Channel CVBS Digital TV Encoder Modulator for Channel Generation

The Thor H-VQAM Real Time Encoder with Digital TV Modulator is a basic real-time hardware encoder combined with a digital TV channel modulator. Thor Broadcast developed this product 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 major world modulation protocols available. Thor carries VQAM systems for QAM, 8VSB, DVB-C, DVB-T, and ISDB-T channel generation. An internal RF combiner is provided for injection of a channel into an existing CATV lineup.

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.
