IRDs - Moto IRD performs bit rate optimization
Motorola announced what it expects will be the first commercial integrated receiver/decoder to deliver three-channel MPEG-4 to MPEG-2 HD transcoding.
With that capability, the new DSR-6300 IRD will enable cable operators to increase HD throughput by up to 50 percent, Motorola said, while offering satellite operators greater flexibility in packaging HD services to their affiliates.
The DSR-6300 employs Motorola’s closed-loop statistical multiplexing. The IRD analyzes video complexity and then dynamically allocates the optimal bandwidth to each program. This process provides bit rate adjustments to services as video becomes more or less difficult to encode.

As a result, Motorola explains, up to three HD services can be efficiently delivered to the home, significantly increasing the number of services that can be delivered over a standard cable 256-QAM feed.
The DSR-6300 simultaneously uses the in-band active format descriptor (AFD) to translate input HD services to an appropriate SD service with proper apect ratio and resolution. This will allow programmers to migrate to HD-only distribution strategies, further freeing up valuable satellite bandwidth for delivering even more HD services.
“The increasing demand for high-quality video requires bandwidth optimization through innovative technologies that deliver efficiencies and smart integration,” said Bob Wilson, general manager for networked video solutions at Motorola. “As we move toward digitization of all content, timely solutions like the DSR-6300 will help our customers directly meet the video explosion with more HD services.”
Field trials for the DSR-6300 are planned with programmers, with general availability in North America and South America beginning in the third quarter of this year.
RF Connectors intros UHF connectors for Heliax cable
RF Connectors, a division of RF Industries, has released UHF male and UHF female connectors for LDF4-50A ½ inch Andrew Heliax cable.
Availability of UHF connectors for Heliax cable was limited to the secondary market when manufacturing ceased several years ago. But RF Connectors’ UHF connectors use the same installation process and tooling required for the discontinued connectors.
Manufactured with white-bronze-plated, machined brass bodies, the new connectors feature silver-plated phosphor bronze contacts and PTFE dielectric. White bronze is resistant to tarnish and has high conductivity and low intermodulation.
The male connector, RFU-502-H1, and the female connector, RFU-520-H1, also work with Andrew LDF4-50A cable, Andrew LDF4RN-50A cable, RFS 810918-001 cable, RFS LCF12-50J cable and Eupen 5128 cable.
RF Industries offers connecting solutions through its operating divisions: RF Connectors, RF Cable Assembly, Aviel Electronics, RF Neulink, RadioMobile and Worswick/OddCables.
Ripley Co. releases Fiber Drop Stripper
The Ripley Co. has introduced a compact FDS Fiber Drop Stripper from its Miller product line.
The product offers a new design for stripping flat drop fiber cable used in FTTH applications, and it boasts a lightweight polymer body.
The one-step stripping action removes the jacket in two locations to expose the dielectric strength members and to allow the quick removal of the jacket.
The tool can easily strip flat drop lengths of 2 feet to 15 feet, and the FDS will strip flat drop fiber cable on the cables.
The Ripley Co. has three product lines: Miller, Cablematic and Utility Tool.
The Miller line, which contains the FDS Fiber Drop Stripper, comprises tools for the fiber-optic and telecom industries, including wire cutters; hand and thermal strippers and slitters for all types of small wire, cable and fiber-optic cable; as well as manual and hand wrapping and unwrapping tools.
