Video Delivery and Challenges: TV, Broadcast and Over The Top

Chapter

Abstract

The TV production and broadcasting industry predates the ubiquitous computing and IP technologies of today. However, just as these advances have revolutionised other industries, they are also causing production and broadcasting to change. Here, we outline the opportunities that general computing and IP delivery offer this industry, and discuss how the precise synchronisation required by TV services could be implemented using these more generic technologies, and how this in turn could lead to newer ways of delivering TV-like services. We first discuss how today’s TV industry has been shaped by its analogue roots, and that the terminology and working practices still in some ways reflect the analogue world. We briefly cover TV history from the 1950s and the evolution of Public-Sector Broadcasting in the UK, before considering how newer services such as digital TV, satellite and video streaming have enabled services, but also throw up new issues around delay and synchronisation. We propose that some of these issues could be mitigated by moving to an IP delivery model, with media elements composed at the client device, and not globally time-locked to precise, system-wide clocks. Finally, we discuss some of the IP delivery technologies such as multicast, adaptive streaming and the newer protocols that are replacing traditional HTTP.
