The Thor H-AC3-CMOD-DVBT modulators are part of the popular CMOD series of digital HDTV encoder modulator systems formally known as VQAM. Like all CMOD systems, this platform is available in three versions for use with over 95% of the worlds broadband TV systems. Advances in technology have reduced component size to the scale that Thor can now integrate every system and component necessary for a digital HDTV headend into a single handheld unit. CMOD systems are combination devices that bundle a real time MPEG hardware encoder, DTV transport stream generator, and agile RF frequency modulator in a single enclosure. Any HDMI live video source can now be converted to an open TV channel for insertion and distribution over cable & antenna TV coax systems. The generated program can be viewed natively on any television set with its built in tuner.

CMOD series units with model numbers including "AC3" indicate that the encoding system includes a licensed Dolby AC/3 audio encoding chip. This is a new feature on Thor equipment, and allows our modulators to be used in a much wider range of application, especially in the United States. When US broadcasters and the FCC came together to establish standards for digital video broadcast; the decision makers were heavily influenced by lobbyists from the worlds largest manufactures. Special interest groups succeeded in designing the first DTV systems around proprietary codecs, such as AC/3 audio. After years of working with Intel, Thor is pleased to announce that official licensed Dolby AC/3 audio chips are now available in most encoder lines. This allows channels generated with a Thor CMOD to be viewed on any strict standards tuner; such as a Motorola or Scientific Atlanta set top box. If you are unsure about what standards and protocols you require, please contact a sales engineer prior to purchase.
