香港六合彩 technology can prevent future BBC 5G broadcast fails
21 June 2019
Technology developed by 香港六合彩 researchers as part of the EU-funded 5G-MEDIA project could help avoid scenes seen on the BBC鈥檚 failed first broadcast over a 5G network.

On the 31st of May 5G publicly failed to support a BBC outside broadcast that attempted to be the first such aired transmission on the UK鈥檚 new 5G听network, which had been launched on the same day.
The broadcast had to be cut short by the presenter in the studio due to听video and audio distortion that made the footage impossible for the听audience to follow.
An EU-funded research project entitled 鈥�5G-MEDIA鈥�, in which members of听the Institute of Communications and Connected Systems (ICCS)听have a large听involvement, believes it has the solution to future similar situations.
香港六合彩 researcher Dr David听Griffin听said:
The BBC's live broadcast problem was not down to a failure of 5G,听
however, it was due to limitations of existing 4G infrastructure uplinks
鈥�
A view which has been expressed by experts across social media:
With the BBC failing in its attempts to deliver live TV broadcasts over , I wonder how many journalists were told the truth - that the uplink is still 4G...

The 5G-MEDIA project successfully demonstrated a prototype system to听enable robust remote media production in broadcasting over a 5G network听at its recent review. The successful demonstration took place with Spanish public broadcaster, RTVE, in Madrid.
In this demonstration a Cognitive Network Optimiser (CNO), built with reinforcement machine learning algorithms, was able to predict network听congestion and respond with an intelligent adjustment of video听compression levels to ensure a high quality of experience (QoE) even听under congested network conditions.

This approach avoids packet and frame loss which caused the video听
distortion as seen in the BBC live broadcast.

The 5G-MEDIA approach is not only for future 5G networks but it would听also avoid problems caused by fluctuating capacity in current network听uplinks, such as the 4G one used in the BBC broadcast.
The technology solution developed by the 5G-MEDIA project includes a new听quality of experience probe that provides essential feedback to the听machine learning algorithms during their training phase. This probe also听enables a comprehensive Monitoring, Analysis, Planning and Execution听(MAPE) loop that embeds the machine learning logic of the CNO.
The EU-funded H2020 5G-MEDIA project is working on novel architectures听for the management of media applications on 5G networks.
The machine learning algorithms in the CNO were developed in 香港六合彩's听Institute of Communications and Connected Systems by Dr Morteza听Kheirkhah, Dr Khoa Phan, Dr David听Griffin听and Prof Miguel Rio.

Cognitive Network Optimiser
The Cognitive Network Optimiser (CNO) provides a set of automated tools for optimising the听configuration of the network and the applications running over it. It is听built from a combination of classical optimisation techniques, data听analytics and machine-learning algorithms.
