Software Analyses Compressed Audio-Video Signals

Rohde and Schwarz (RandS) has launched the Vega Suite, a set of software tools designed for in-depth, offline analysis of media files on a PC. Broadcast operators and service providers can use this software to find signal faults and optimise content. Manufacturers of DTV components use the RandS Vega Suite to check that their products are standard compliant, for quality assurance testing, and to improve the performance of their products.

Rohde and Schwarz said the software is suitable for analysing compressed audio and video signals and MPEG-2 transport streams. To ensure network availability, broadcast operators and service providers can use the RandS DVM and RandS DVMS monitoring systems and the RandS ETL TV analyser to immediately detect faults in live signals and record the faulty signal segments. The RandS Vega Suite makes it possible to analyse these segments and their video and audio characteristics in detail on a PC Signal faults are quickly found and eliminated, allowing operators to optimise the quality of their content.

Visualisation options simplify analysis while the save function makes it easy to document results. The RandS Vega Suite supports the latest standards and technologies, making it useful for developers of DTV components and devices such as encoders, multiplexers and transcoders. The company said the software is suitable for analysing MPEG-2 transport streams (DVB, ATSC, ISDB) and MXF files. The H.264, H.264 SVC, H.264 MVC, H.263, MPEG-1, MPEG-2, MPEG-4, AVS, VC-1 video formats can be analysed.

The MPEG-1/MPEG-2 Audio, Dolby Digital, Dolby Digital Plus, Dolby E, AAC, HE-AAC and MP3 audio standards are supported. Data streams such as teletext, DVB subtitling, closed captioning, XDS and EPG can also be analysed. Manufacturers can use the software to check their products for compliance with relevant standards and for interoperability, coding efficiency and audio-video synchronisation. To save time, batch processing can be used to automatically analyse multiple files. The RandS Vega Suite software was developed by Interra Systems.

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.
