TANDBERG Television MPEG-4 AVC to power delivery of New Zealand digital terrestrial TV
Kordia and TVWorks in New Zealand have selected TANDBERG Television’s digital terrestrial television (DTT) headend system for the delivery of the Freeview New Zealand DTT service.
New Zealand's Freeview DTT network will deploy the latest MPEG-4 AVC solutions to provide about 75 percent of New Zealanders with a new HDTV service, as well as SD programming. Trials are set to commence this month, with a launch date set for early next year. Freeview is a free-to-air digital TV service currently transmitting SD programming in MPEG-2 across the country via satellite direct-to-home (DTH) service.
The DTT system will use a range of TANDBERG Television solutions including the iSIS 8000 IP headend and MPEG-4 AVC encoders. By using the latest MPEG-4 AVC video compression and IP technologies, Kordia and TVWorks can cost-effectively deliver more channels in less bandwidth, while still maintaining high-quality pictures.
At the heart of the DTT headend solution is the TANDBERG iSIS 8000, which includes best-in-class video encoding, IP multiplexing and new receiver/decoders. The system is brought together under a single control and management system, nCompass. The TANDBERG MX8400 IP multiplexer is a next-generation solution that will provide Kordia and TVWorks with an open-standards, IP-based headend. The combination of Reflex remote statistical multiplexing over IP and an advanced multiplexing architecture ensures maximum usage of available bit rate.
Further bandwidth efficiencies are achieved by the use of the TANDBERG EN8000 MPEG-4 AVC encoders, based on the company's next-generation compression platform.
