The broadcasting industry has undergone enormous change since the switch to digital with television and radio now being increasingly accessed via the Internet and smart phones.
Current research is investigating the impact of the move to ultra-high definition television (4K and 8K) which offers picture qualities far in excess of that achieved with current high definition standards. The challenge is being able to transmit high quality digital pictures efficiently over both wired and wireless networks. Therefore current work is assessing the relative performance of codecs, the optimisation of those codecs and an assessment of the consequent traffic loads generated on the delivery networks.
Internet TV and the emergence of the smart TV has resulted in a huge increase in the amount of television content that a given user can now access. The challenge for content providers is to provide the user with an easy to access interface for navigating, searching and selecting relevant content. Current research is therefore examining the use of meta-data to aid searching, the design of new intelligent search algorithms and the development of new and potentially virtualised set top boxes which allows for the more rapid deployment of new services and channels.
Community TV is a well established concept for delivering content that has been generated within the local community and intended to be consumed by the local community. However, with the move to digital services, hyperlocal has taken on a new lease of life with content now being able to be generated by individuals and embedded with location information. Research is therefore investigating how hyperlocal services can be reinvented for today’s audience. This requires the ability to appropriately tag content with location information, to catalogue such content to form a virtual channel and to develop search algorithms which can locate content that has a relevance to your location.
