TVBEurope 75 NAB 2012 Preview PESA Web-based router control By Jake Young


Cattrax Web uses basic internet components and blends them with PESA’s routing system controllers


PESA IS debuting its Cattrax Web browser-based router control software. Expanding on the capabilities of PESA’s local network-based Cattrax software, Cattrax Web uses most common web browsers as the client interface to monitor and control routers in locations around the world. Cattrax Web is compatible with the full line of PESA routers and can control matrix

sizes from 16x16 to 1024x1024. It operates over Ethernet via TCP/IP and communicates directly with the PESA PERC2000 router control system. Cattrax Web pulls its configuration from the PERC2000 control card inside the routing matrix or an external 1 RU chassis assembly. Once configured, Cattrax Web can be used like any remote control panel linked to the system. Based on the Microsoft


Windows platform, Cattrax Web Nevion Pixelmetrix OMG for OTT By Jake Young


PIXELMETRIX WILL unveil its new OTT Media Grinder (OMG), a comprehensive system for validation of Over-The-Top Delivery Infrastructure. The OMG enables operators to qualify and periodically audit OTT Service Quality by simultaneously emulating thousands of OTT clients — generating large amounts of OTT transaction traffic into the network. The OMG simulates thousands


of OTT clients (iPhone, iPad, etc) with multiple user-defined behaviours. Pools of clients can behave well (for example, consume content to the end), while other pools of clients can


randomly change speeds, drop connections, or flap between adaptive bitrates. To quantify the unique QoS/QoE performance factors for OTT, Pixelmetrix has developed the comprehensive VideoMargin Metrics, which give complete insight into the OTT delivery. Measuring network, HTTP and video layer performance, the seven VideoMargin parameters measure each aspect of the delivery domain spanning content server, network, authentication, individual client behaviour and collective client behaviour as well. Consolidated service availability is also provided as a single number in a familiar five nines type of representation.


Packaged in a compact


1RU form factor, dedicated GigE Interfaces are available for management and Load Generation. The OMG can be operated standalone in a single location, or in a distributed, coordinated, multisite configuration where loading multiple OMG systems provide visibility of service quality across the entire network. Pixelmetrix develops a


host of IPTV and Preventive Monitoring systems that offer unique attributes and versatility, allowing operators to achieve end-to-end visibility and keep tabs on their network architecture. SU5415


Compression and transport offerings


By Jake Young


NEVION WILL enhance its compression offerings with the introduction of an advanced H.264 encoder and decoder solution. The Ventura VS904 provides H.264 4:2:0/ 8-bit and MPEG-2 4:2:0/4:2:2/ 8-bit capability with bitrates from 2Mbps to 80Mbps. A myriad of audio codecs are also supported including SMPTE302 pass through, MPEG-1 Layer II, HE-AAC, AAC-LC, and AC-3. In addition, the VS904 offers a low latency option of 250ms (end-to-end) while maintaining high visual quality. The Ventura VS901- IED-GEP allows Nevion’s widely- deployed JPEG 2000 solution to provide


mathematically lossless compression for HD-SDI transport supporting bitrates up to 800 Mbps. Using JPEG 2000 lossless filters, it can now achieve mathematically lossless compression with some video content, while with highly complex content, gains in video quality have been attained that previously weren’t possible. Even with highly complex content, the use of lossless filters results in up to 10dB of PSNR increase over the use of lossy filters at intermediate bitrates. SU2019


is compatible with Windows Server 2003, 2008, or Windows 7 operating systems. It resides on a customer provided network server and supports Microsoft IIS (Internet Information Services) or Apache HTTP Server. The software offers customised features such as salvos, hot takes, and individual lock/unlock of sources or destinations. Plus, single or multiple destination blocks can be switched simultaneously.
