Tektronix Will Ensure Video and Audio Quality for Cogeco Cable Subscribers

Tektronix, the market leader in broadcast video test, monitoring and analysis solutions, today announced that company’s flagship Sentry® digital content monitor has been selected by Cogeco Cable, Canada’s fourth largest cable operator, to help ensure their video services are delivered with exceptional quality.

After carefully evaluating several competitive solutions, Cogeco Cable selected Sentry for its comprehensive approach to ensuring its subscribers consistently enjoy the best possible viewing experience. Sentry’s advanced monitoring capabilities enable the early detection and diagnosis of video and audio errors, which can help operators fix the underlying issues, and in many cases prevent costly in-home service appointments.  

Cogeco Cable will deploy Sentry’s advanced Quality of Experience (QoE) and Perceptive Video Quality (PVQ) modules. With QoE, Sentry does a full decode of each MPEG packet looking for structural errors that cause picture and audio impairments. Each impairment is scored based on the severity, taking into account the frequency, duration and position on viewers’ screens of each impairment. In addition to QoE, Sentry’s PVQ module detects picture blockiness and other artifacts caused by over-compression using an eMOS (effective Mean Opinion Score) based scoring algorithm. Sentry’s combination of advanced QoE capabilities and PVQ provides Cogeco Cable with the most comprehensive real-time monitoring and alerting system available today.

“Maintaining subscriber growth while reducing overall operating costs is a key initiative and we believe Sentry’s exceptional monitoring and management capabilities will help us achieve our goals,” said Jacques Gravel, VP of Network Services.  “Everyone at Cogeco Cable is committed to service excellence and deploying Sentry is the latest example of this commitment.”

Cogeco Cable will initially deploy Sentry in its master headend, where it will be comprehensively monitor the standard definition (SD) and high definition (HD) programming throughout the company’s Ontario systems.  Cogeco Cable will configure and manage its Sentry units using Tektronix Medius™ applicat ion.

“Cogeco Cable has a well-deserved reputation for service excellence and their choosing Sentry shows their commitment to providing services with the best possible quality,” said Eben Jenkins, general manager, Video Product Line, Tektronix.  “Sentry’s cutting-edge QoE and PVQ monitoring capabilities are perfect for forward-thinking operators like Cogeco Cable that recognize quality is a competitive advantage in today’s increasingly crowded multi-channel video market.”

The award-winning Sentry is the industry’s premier content monitoring solution, proven in deployments with nine of the top 10 U.S. cable operators and now four of the top five Canadian operators.

Sentry utilizes advanced deep packet inspection (DPI) technology to give cable operators unparalleled visibility into network anomalies at the IP and MPEG layers at all critical locations in the network.  This enables the quick identification and diagnosis of video and audio errors regardless of where they occur in the network; from ingest at the headend through the network edge just before it is delivered to the home.  This unprecedented level of event specific information helps operators speed the repair of the underlying issues to limit the impact to viewers’ quality of experience (QoE).

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
