Need real-time analysis of video streamed using the key Adobe, Apple and Microsoft streaming protocols? What about analysis of video quality and buffering performance plus reports detailing performance and Quality of Experience metrics? Telchemy says it has the answer.

The Ga.-based provider of VoIP and IP video performance management technology, now is offering VQmon for Streaming Video, which it says “sets a new standard for measuring the quality of video streaming services. The new offering is part of Telchemy’s VQmon product family that includes a range of QoE measurement modules for VoIP, videoconferencing, IPTV and TCP video streaming.

According to company literature, VQmon analyzes the TCP stream carrying the video, the playout buffer dynamics and the video stream itself. Analysis of the TCP stream provides key information on network bandwidth, the impact of congestion and server performance. Real-time emulation of the playout buffer allows buffer fill and empty rates to be measured; and it detects if buffer levels get too low, which leads to gaps in playout. Video stream analysis provides video quality estimation and key information on the
encoded stream.

In addition, VQmon computes MOS scores (measures of QoE) that reflect video encoding parameters, video resolution and playout gaps using an advanced perceptual model. VQmon can be integrated directly into network equipment, routers, handsets, client applications and test equipment, and it uses few available processor and memory resources.
