Harris Corporation announced that CTV, the Taiwan television broadcast network, has purchased 16 of Harris Broadcast Communications Division’s NetVX(TM) High-speed Network Systems and upgrades for Harris’ FlexiCoder(R) Encoding System. The equipment will be installed during the second phase of the network’s digital rollout for the distribution of its TV services.
At CTV, the NetVX system will receive feeds from either the Chung Hwa telecom network via fiber or CTV’s digital microwave system to drive the DVB-T transmitters at the network’s remote sites. At regional sites that provide localized encoding, the NetVX system will be equipped with a SD encoder that will encode audio and video from the local station to MPEG-2 and multiplex that signal into the final multiplex.
With its ability to establish links with all packet-based (ATM, IP, and
microwave) services and receive satellite signals for news sendback and local news drop and insert, the NetVX system enables broadcasters to efficiently and cost-effectively move media (analog or digital video, audio and data) between physically disparate locations simultaneously. This capability will help CTV to integrate the monitoring and control of the DVB-T transmission and transmitters via IP over ATM or IP over MPEG.
At NAB2004, Harris featured a major enhancement for the NetVX system, a Gigabit Ethernet interface with the extended capability for transporting video over IP networks. The Gigabit interface is capable of high-speed file transfer and transport of 64 real-time, bi-directional streams for video services. It also features Forward Error Correction, which automatically corrects for packet loss often found in networks.
