Hunan Cable Group has launched a new HDTV service and expanded its on-demand offering, all relying on a number of products supplied by Harmonic.

Hunan Cable is using Harmonic's Ion AVC HD multi-channel encoders, ProStream 1000 stream processing platform with DiviTrackIP statistical multiplexing, NSG 9000 universal edgeQAMs, and NMX Digital Service Manager.

This deployment provides Hunan Cable Group with a fully integrated IP headend, encompassing compression, statistical multiplexing, scrambling, VOD edge processing and network management. Harmonic's compact, power-efficient MPEG-4 AVC (H.264) HD encoders deliver up to four channels within a single 1-RU chassis, which the vendor said lowers operating expenditures while enhancing video quality.

The modular 1-RU ProStream 1000 stream processing platform handles MPEG-2 re-encoding, multiplexing, scrambling, and advanced processing of the MPEG streams.

Harmonic said that Hunan Cable Group is the first provincial-level cable network in China to provide HDTV services.

HCG was founded in 2007 after consolidating approximately 100 local networks in Hunan Province. HCG currently provides 110 SD digital TV programs and 11 HD TV programs for over 5 million subscribers. HCG also offers advanced interactive services such as VOD, Time-Shift TV, and Internet broadband access.
