DATA SHEET<strong>IxLoad</strong> TM : <strong>IPTV</strong> <strong>and</strong> <strong>Video</strong><strong>IxLoad</strong> provides a comprehensive solution for testing <strong>IPTV</strong> <strong>and</strong> <strong>Video</strong>networks <strong>and</strong> services. <strong>IxLoad</strong> emulates millions of <strong>IPTV</strong> Broadcast <strong>Video</strong><strong>and</strong> <strong>Video</strong> on Dem<strong>and</strong> (VOD) subscribers to assess the true subscriberQuality of Experience (QoE).<strong>IxLoad</strong> can be used to i :• Benchmark the performance of video servers• Measure the channel change performance of an <strong>IPTV</strong> deployment• Measure the ability of a transport network to carry video data in additionto data <strong>and</strong> voice. Measure the impact of network characteristics onvideo quality• Stress test middleware devices such as encoder systems, digital mediarights management (DRM) devices, billing systems, ad-insertion devices<strong>and</strong> conditional access systems• Measure the perceived quality of the video delivered to the end-user• Test performance of key <strong>IPTV</strong> infrastructure services like DHCP, DNS<strong>and</strong> AAAFeatures <strong>and</strong> Specifications• Emulation• Emulation of Broadcast <strong>IPTV</strong><strong>and</strong> <strong>Video</strong> on Dem<strong>and</strong> (VoD)<strong>IPTV</strong> subscribers• Simulation of Microsoft TVclients <strong>and</strong> servers• Microsoft TV serversincluding A, D <strong>and</strong> V-servers• Support for ICC (InstantChannel change)• Configurable D to A serverstream switch behavior forMS TV clients• Support for IPv4 usingIGMPv1, IGMPv2 <strong>and</strong>IGMPv3• Support for IPv6 usingMLDv1 <strong>and</strong> MLDv2• <strong>Video</strong> codecs• MPEG2, MPEG4, H.264 <strong>and</strong>others over MPEG2-TSstreams• MPEG4, H.264 <strong>and</strong> WM9(advanced video bundle)• Support for native MPEG4transport of High definitionstreams• Support for single-program(SPTS) <strong>and</strong> multi-programtransport streams (MPTS)• Quality of Experience (QoE)• <strong>Video</strong> quality metrics tomeasure both transmissionquality using MDI <strong>and</strong>perceptual video qualityusing TVQM• <strong>Video</strong> quality metrics on aper-subscriber basisiSome features require IxAnalyzer.
