IPTV/Video on Demand (VoD)


IPTV is becoming a big hit with the general public, but doubts are very frequently expressed about its quality and reliability. Increased success on mass markets will therefore be possible only if quality baselines are set up at the same time.

ip-label measures the quality of IPTV transmissions and VoD (video on demand) as perceived by the end user:

    • We give internet consumers insight into the quality of services offered by ISPs.
    • We help IPTV service providers optimize their infrastructures in order to provide optimum quality of service.


Key indicators

    • channel availability and accessibility
    • frozen image rate (freeze): fleeting and permanent freezes
    • channel switching time
    • time lags between the broadcast (digital terrestrial television, satellite, etc.) and the channels received via ADSL
    • video quality of the image (video MOS)


To measure image quality, ip-label relies on the objective methods for evaluating video quality recommended by the International Telecommunications Union (ITU), J 144-R: objective perceptual video quality measurement techniques for digital cable television in the presence of a full reference. These methods make it possible to assess the quality of the entire digital delivery infrastructure:

    • quality of video sources
    • quality of encoding/translation of transmissions
    • quality of the transmission network
    • quality of decoding


Video on Demand (VoD) and interactive TV services

Today the market for Video on Demand via standard television, IPTV, or the web is booming: how can we satisfy customers’ increasing demand for video while maintaining an acceptable standard of quality?

Video over IP is also being included in a new approach to collaborative work. More and more multiple-site companies are using video-conferencing to make it easier to exchange information between colleagues. Finally, video makes it easier to access professional training courses and exchange know-how.

ip-label measures the quality of VoD transmissions as perceived by the end user. We help ISPs, television stations, and video over IP users and providers optimize the quality and availability of the service.
