Video Quality Test Solutions
Video telephony applications are being widely used in our day to day lives and the demand for better quality keeps growing. The proliferation of Video Chat or Video Conferencing equipment and services offered to consumers and enterprises is indicative of this shift. As a consequence of the growing demand for video, service providers require to ensure that the video quality delivered meets customer expectations. GL's Video Test and Monitoring solutions provide next generation test tools that provide video analysis to gauge the quality, bulk video call generation capability to stress test network, and end-to-end video test tools to perform tests on multiple devices and networks. These test solutions are briefly discussed below.
Video Conference Testing
GL's Video Quality Testing Solution comprises of end-to-end Video Conference testing, using VQuad™ with Video Application Controller (VAC), providing both Video and Voice MOS between two VAC Agents. VAC Agents can be installed on Windows, Linux or Android devices (test from your Android phone or tablet).
GL's VQuad™ solution provides an automated method to simultaneously test Voice, Data and Video from any mobile device.
With the introduction of GL's VAC™, Video Conference test capability, GL's VQuad™ with VAC solution supports end-to-end Video Conference testing between any two VAC agents, with support for variety of video codecs including H261, H263, H263+, H264, MPEG VIDEO, MPEG 4, MPEG 2 , and VC1. Agents, or end points, can be installed on Linux, Windows® or Android devices. In other words, test Video Conferencing between an Android phone and a Windows® PC.
The VQuad™ with VAC solution is fully automated using VQuad™ scripting for testing a variety of scenarios with access to all video parameters such as Codec, Frame Rate, GOP Structure and Image Size.
Bulk Video Call Generation
GL's MAPS™ SIP provides a means for Bulk Video Call generation, simulating many Video Calls from a single MAPS™ SIP system. As part of this solution the GL's PacketScan™ can provide real-time Video Call Analysis of the video generated over the SIP call using a non-intrusive connection to the network.
GL's MAPS™ SIP with Video Calls option is a bulk SIP call generator which can simulate any interface within a SIP network including multiple User Agents.
As a new enhancement, the RTP Video Traffic Generation capability is now added to GL's MAPS™ SIP Emulator. It can generate hundreds of concurrent video calls with codecs such as H.263, H.264 and VP8.
Bulk video call generation capability helps in conducting load and performance tests on devices or network under test. MAPS™ also supports transmission and detection of various RTP audio traffic entities for example: digits, voice file, single tone, dual tones and FAX.
Bulk Video Call Analysis
PacketScan™ with Video QoS capability addresses customers long felt need of Video Call Quality in IP networks.
PacketScan™ can listen on a Mirror port of a Switch to capture all IP traffic in the network.
PacketScan™ can capture hundreds of video (H.263 and H.264) calls simultaneously and can measure video quality metrics such as Media Delivery Index, Packet Loss, and Delay on each leg of the Video Call
PacketScan™ can also perform similar voice quality measurements such as MOS, R-Factor, Packet Loss,and Jitter on the associated audio RTP sessions of the video call and hence gives the complete call quality report.
Triggers and Actions feature in PacketScan™ allows user to filter calls of interest based on ‘Video Quality' parameters such as high MDI values or Packet loss percentage.
User can also define a set of actions like Save Call Trace, record to *.WAV file, Save Call Summary, and Generate Alarm on the filtered calls. Saved files can be opened offline for detailed analysis.
