With its unique QoE monitoring technology*, Witbe carried out a study of digital TV services (via DSL, cable, FTTH, satellite and DTT), looking at 30 operators in 16 countries on 4 continents.
The average channel change time measured using P+/P- was 1.9 seconds. If the user chooses the channel number, the change time came out at 3.4 seconds with a more uniform distribution than in P+/P- mode.
Witbe noted important variations between operators but also between technologies. Witbe distinguished amongst these factors:
The broadcasting technology: satellite is twice as slow as IPTV
The maturity of the services tested: services launched recently are often slightly slower
The IPTV system used: for example, Microsoft Mediaroom platforms have the best results in P+/P- mode, with an average of 0.6 seconds. Still channel change times of 0.7 seconds can be measured on other platforms.
The performance of the decoder and notably the buffering policy.
The presence of retransmission mechanisms (eg Cisco VQE) or forward error correction which, when they are not combined with rapid channel change systems, can degrade the quality.
This study also allowed qualification of service availability (black screen or error screens, sound but no image, image but no sound etc) the image quality as well as sound quality.

About Witbe
N-play usages such as watching TV, using VoD services, making phone calls or accessing the internet via landline or mobile networks have revolutionized the way operators work and their areas of responsibility.
To respond to the new challenge of tests and end-to-end service monitoring, since 2000, Witbe has been developing an innovative approach to measuring the actual quality delivered: Quality of Experience monitoring (QoE).
Witbe’s unique technology provides indicators of perceived quality measured by its robots, which continuously reproduce user behaviour. Witbe, thanks to its MOS algorithms qualifying real-time image and sound quality from the STB, has been regarded since 2004 as the reference for IPTV services monitoring. Witbe works with the main operators throughout the whole word: Spain, France, Italy, Poland, Portugal, Switzerland, Netherlands, Austria, Greece, Marocco, the UK, Singapore, Korea and Taiwan amongst others.
