Bandwidth resources needed to broadcast channels on 4K or in 8K are just not available as of today. However, the problem is not only related to non availability of bandwidth, it is mainly connected with investments and time it takes to upgrade the  whole chain of production, post-production and distribution. For 4K there exist at the time, at least one experimental ‘flag’ channel broadcast from each major satellite operator. There is however also a problem of availability of content, i.e. television footage produced in 4K. It is expected that – by 2018 – some broadcast in 4K will be on-air. It would be mere futuristic exercise to predict a timeframe for availability of broadcasts in 8K.
