IQDialogue™ SDV Desktop Edition

IQDialogue™ is a software application for your PC that analyzes, monitors, and troubleshoots Switched Digital Video (SDV) networks. IQDialogue identifies the various SDV protocols in a comprehensive and familiar web-based format, which in turn provides information on the SDV service delivery platform. IQDialogue allows users to measure channel change timing, control plane signaling, Mini-Carousel, and many other parameters (IGMP, DHCP, etc.) allowing for quick and accurate fault identification.

SDV Signaling Overview IQDialogue provides visual representation of all aspects of the Switched Digital Video signaling. Classification is done in real-time on type and status, with easy to understand color coding. The user can switch back and forth between the various status screens, and operational mode (analysis, stim) with just the click of a button. SDV message filtering can be performed on a per Service-Group level for more targeted analysis. Capacity and processing abilities are only limited by the host platform and IP interfaces available.

SDV Client Emulation When analysis just isn’t enough, IQDialogue allows for the emulation of many SDV clients (tuners), in one or many Service Groups. These clients can interact in real-time with the SDV network elements, and perform functions such as SDV client registration and channel changes. Some of these functions can also be automated to perform bulk operations (for example, 500 SDV clients performing a channel change per second for 12 hours). The SDV client emulation tool also allows for the crafting of impaired messaging. Fields such as “Service Group ID”, “TSID”, “SourceID”, can be manipulated to offer any value desired.

Recording and Playback In addition to real-time monitoring, IQDialogue allows the user to playback and analyze any compliant Libpcap capture file. IQDialogue can also create and provide a Libpcap capture file for archiving and offline analysis.
