China's Shenzhen Topway Taps Harmonic to Power New HD Channels and HD VOD Services

Harmonic said Tuesday that Chinese cable operator, Shenzhen Topway Video Communication, has expanded its HDTV and VOD services using Harmonic headend and edgeQAM solutions. According to the company, the deployment of its technologies has allowed Shenzhen Topway to offer new HD VOD services; expanded on-demand capabilities, including time-shifted TV; and 13 new HDTV linear channels.

Harmonic says that the solution it provided for Shenzhen Topway included its ProView integrated receiver/decoders (IRD's), its Electra 7000 MPEG-4 AVC (H.264) HD encoders; its ProStream 1000 stream processors; its NSG 9000 edgeQAM's; and its NMX Digital Service Manager. According to the company, the ProView IRD's are used to receive and decode digital content sources; the Electra 7000 AVC encoders enable Shenzhen Topway to deliver up to four full-resolution, variable bit-rate HD services within a single 1RU chassis; the ProStream 1000 stream processing platform handles multiplexing and scrambling of the MPEG streams; the NSG 9000 edgeQAM's provide reliable edge processing for on-demand services; and the NMS Digital Service Manager provides Shenzhen Topway with an "easy-to-use yet powerful" solution for network configuration and management.

Shenzhen Topway claims to currently have over a million digital subscribers--a number that it says will grow to three million "after consolidation with two surrounding areas." Since 2002, the operator says, it has been upgrading its network to a "two-way interactive system."
