This paper discusses how a video model can be developed and evolve from preparing content for a single specific service (e.g. QAM) to an architecture where multiple types of video services (e.g. SDV, Adaptive Streaming, Mobile) can subscribe to a common set of video feeds. Moving towards this architecture can increase scaling efficiencies in transcoding and monitoring, improve content quality consistency across platforms and allow for innovation in services/platform/devices. Legacy services and new multi-streaming technologies will be discussed. Additionally, this paper will cover common encoding approaches for acquisition, transcoding and service wrapping. These types of architectures will be needed to transport content efficiently for existing and new delivery infrastructures.
