Virtualização de estúdios móveis na produção de conteúdos audiovisuais em direto

Abstract

Live TV production, due to its distributed nature, requires broadcasters to deploy equipment and human resources to several different places, increasing production's costs. As the performance and cost-effectiveness of IP networks grow, broadcasters can use this to handle realtime production-quality video and audio that is expected in a professional environment. Similarly, the evolution of virtualization's technologies on the cloud and the efforts developed to provide solutions of cloud virtualized, elastic, controllable cloud environments, enables that this technologic stack may be considered for time-critical applications, such as a live TV production. This master thesis addresses live TV production using RTP to transport audio and video feeds through IP. It ought to demonstrate that live TV production can be virtualized into the cloud, taking advantage of its benefits. While using cloud's benefits to perform time-critical operations in a distributed manner, the developed prototype allows a production team to receive audio and video streams, multicast them at high quality locally and publish them as web feeds to a web interface. The work developed shows an architecture that can be potentially used to perform other operations that may occur in a live TV workflow, such as video switching.
