Headend equipment

CableServ releases module

ANAHEIM, Calif.-CableServ is introducing its new RF Redundancy Transfer Switch Module for use with its CHAS Headend Amplifier System. The module takes an "A" and "B" input from any RF source and will automatically switch to the secondary "B" source if signal levels from the main "A" source drop below set threshold levels. 

The switch features a -20 dB test point, a threshold adjustment for tweaking the sensitivity of the switching based on signal level, and a forced transfer button for easy set-up and testing.


Terayon cooks up new network flavor of CherryPicker

SANTA CLARA, Calif.-Terayon Communication Systems Inc. has unveiled the DM 3200 Network CherryPicker, the latest addition to its line of digital streams management systems, and the first component in the company's new Distributed Media (DM) platform. Terayon says that its DM platform will allow cable operators to roll-out digital cable service faster while reducing costs by enabling them to distribute digital video content throughout a cable system efficiently from a central headend, while maintaining dynamic program management at their local headends.

By aggregating source content from satellite, video servers and encoders at a central headend and then dynamically routing and processing this content through an ATM, Packet-over-Sonet or IP-based network, operators can realize savings by requiring costly digital video equipment only at the central headend, and not in local headends. 

Centralizing digital video equipment in central headends with the DM platform can also speed the pace of digital cable roll-outs by reducing equipment installation at local headends. 

In addition to centralizing the aggregation and distribution of digital video content at a central headend, Terayon's DM platform also gives local headends flexibility in managing the content they receive to meet the needs of their local subscribers. For example, the local headends can "groom" customized programming line-ups by dropping unwanted channels and adding new local programming to the line-up received from the central headend. 

Complementing the benefits of networked video distribution, the DM platform also enables operators to optimize their available bandwidth to deliver the maximum number of channels and broadband voice, data and video services.

As a standalone unit, the new CherryPicker can be deployed for grooming, digital-into-digital advertising insertion and a variety of other digital video applications, and later be integrated with the other components of a complete DM platform, when available. 

Compared to earlier CherryPicker models, the DM 3200 delivers more than twice the stream processing capabilities in a much smaller chassis, while offering common network interfaces supporting IP, ATM and Packet-over-Sonet, according to the company.


Scientific-Atlanta adds to line of Continuum headend products

ANAHEIM, Calif.-Scientific-Atlanta has introduced new modulators to its Continuum Headend Systems product family. The latest additions are the 9825M and 9825S modulators, and 9815 Rear Interface Module (RIM). The 9825M full frequency NTSC modulator provides a monaural NTSC television signal on any selected cable TV channel between 50 and 870 MHz, while the 9825S full frequency NTSC modulator with integrated stereo encoder is designed for cable television headends that must encode locally originated or satellite-delivered stereo audio programming in BTSC stereo format. 

The 9815 Rear Interface Module mounts in the headend chassis to configure a slot for a specified application module, while the 9811 controller module mounts in the first slot of the Continuum chassis and provides in-chassis control and backup features for the entire portfolio of Continuum application modules, including the new 9825M and 9825S.


Vela launches Linux-based, networkable EAS controller

ANAHEIM, Calif.-Vela has released a networkable controller for EAS (Emergency Alert Systems) and SIS (Subscriber Information System) applications. The new Linux-based NDU (Network Data Unit) enables browser-based control and cost-effective administration of system operations via the Internet or an intranet.

At 2 RU in size, the new NDU is designed for all types of operation-those relying primarily on RF, IF and baseband EAS solutions, as well as those employing the company's patented ACM text messaging system for non-disruptive EAS communications. The NDU is capable of controlling up to 64 ACM modules and 254 channels. Additional options include remote telephone access and automatic alphanumeric paging through Vela's FrontPager.

The NDU also offers networkable control for EAS and subscriber information services. It provides the ability for Internet and intranet operation, and because each NDU has a unique IP address, multiple NDUs can be administered from multiple locations or from a single location, and remote access can be achieved without any special setup. From a single location, users can remotely administer multiple headends through standard Web browsers over any type of network.
