DTV Solution for HFC Network

DTV Solution for HFC Network

HFC broad band network has the super capacity to transmit digital signals, it can directly provide thousands of families with much increment operation, such as digital TV, digital broadcasting, internet, VOD, etc.

GOSPELL offers the entire set of digital headend equipments, CA, STBs, etc. It also offers the service of designing, installing, testing and so on, then finishes Golden Key project.

Features

Saving channels------every 8MHz can transmit 6~12 PAL/NTSC TV programs when 64 QAM is adopted.

Good quality picture------digital signals are decoded and reverted in receiving equipments, which ensures the high quality.

Far transmission distance------digital transmission has a relatively low condition demands, the direct transmission distance is far, but also capable to carry out the digital signals recycling and repeating so long distance transmission could be operated.

CA------digital system can carry out CA conveniently. It simplified the authority of  subscribers  and charging process. Self-contained system softwareconditional access system software(CAS), subscriber management system software(SMS), network management system software (NMS), electronic program guide software(EPG).
