- Haivision has collaborated with Zixi, LLC, to incorporate Zixi technology directly within low-latency Makito™ encoder and decoder HD H.264 appliances. Zixi enables broadcast-quality HD video transport over low-cost public Internet connections. Haivision's Makito is an ultra-compact, low-power, easy-to-set-up and deploy appliance that can now be ordered with Zixi ready™ capabilities. The Makito/Zixi solution is ideal for electronic news gathering (ENG) where remote live sites do not have access to custom network or satellite services and lead times for breaking news stories are short. The solution is also ideal for connecting facilities over low-cost and readily available Internet connections, saving thousands of dollars every month compared with managed-performance network services. Zixi overcomes IP transport challenges specific to video through advanced multimedia time synchronization and error recovery technology that accommodates the sometimes severe packet loss and end-to-end latency issues associated with the public Internet. Zixi also provides Internet services to distribute up to full HDTV (1080p/60fps) video to multiple destinations simultaneously, including Zixi ready Makito decoders and popular players with the Zixi Client™ software. Zixi ready Makito and Barracuda encoders and Makito decoders are now available from Haivision. To enable video delivery and management with Zixi technology, customers can obtain licenses and services directly from Zixi, LLC.
- Miranda Technologies has expanded its range of headend monitoring and signal processing solutions with its new Axino multi-program, IP transport stream loudness control processor. The new processor addresses all common loudness problems using Automatic Loudness Control, including excessive channel-to-channel and program-to-program variation. For instance, when installed downstream of the advertisement insertion equipment, it will prevent excessively loud commercials, and will improve the quality of service for subscribers. Axino can process multiple audio services, including Dolby Digital (AC3), from a single or multiple programs carried over IP. The audio services are extracted, measured, processed for loudness, and remuxed into the original program. The processor ensures that the audio loudness matches the desired target by constantly measuring the levels, using ITU-R BS.1770, and then applying real-time audio level correction. The result is a smooth and consistent audio loudness at all times, and across all television channels. To assist with compliance, Axino logs measured loudness across all the processed channels. These logs can be viewed and the contents analyzed to identify any problematic audio segments. They can also provide proof of loudness monitoring and control activities.
- Quintech Electronics and Communications Inc. will be displaying their new Q-Flex Modular Chassis at NAB. The Q-Flex is a compact (4RU) housing environment for Quintech RF modules. The Q-Flex chassis provides 21 multipurpose bays, which support either single or double width modules. One chassis can house up to eight 1X16 BNC splitters and combiners and two 150W internal power supplies in a redundant configuration. The system may be powered by QPS series hot swappable supplies, external power supplies, or can be stand-alone if populated with passive RF modules. The Q-Flex chassis contains a proprietary backplane to facilitate high speed inter-module communication, module addressing, and power supply status monitoring.
- At NAB 2011, Telecast Fiber Systems will introduce a new line of SMPTE cable assemblies specifically designed to meet the demands of HDTV broadcasting. The heavy-duty, stainless steel assemblies offer high levels of performance, reliability, and durability for fiber connectivity between HD cameras and camera control units, in studio as well as outside broadcasting configurations. The new SMPTE cable assemblies are equipped with heavy-duty SMPTE 304M hybrid fiber connectors with solid stainless steel shells covered with a full-length rubber strain-relief boot to protect the connector from the rigors of outside broadcasting. The assemblies are fully backward-compatible with triple-plated brass connectors, and are rated for more than 20,000 mating cycles — a 50 percent increase over previous assemblies. Highly durable, the assemblies can survive a two-meter drop onto concrete. The innovative design is a direct result of new synergy between Telecast Fiber Systems and Belden, Telecast's new corporate parent.
