Not long had our new top box system installed,seems ok but being keen follower of horse racing I find the at least 30 second delay most frustrating.The old system I had very little delay so why with the most up to date equipment is this happening.
The 28-30s delay on live channels is due to Vodafone TV using streaming technology (adaptive bitrate streaming as we call it). You will find the same delay on all streaming services, including Netflix and YouTube. (Of course, much online content is on demand, and you will not notice the delay.) It is simply the way that modern streaming protocols are designed. You will also find that most TV services will move to this technology in the future.
Having said that, there is a lot of research and development going on at the moment to reduce the delay of streaming protocols. We are actively working with our vendors and suppliers to take advantage of this development as it becomes available.
