  New system architectures for broadcast workflows More than 20 years ago, while moving from analogue to digital, the broadcast industry started integrating computer-based appliances into its workflows. Broadcast equipment manufacturers progressively replaced dedicated hardware video processors with software implementations executed on server computers equipped with video interface cards. Undoubtedly, that evolution amplified over the years until reaching a sufficient confidence level to consider moving complete video production facilities into data centres. Inside such IT-centric installations, video data flows through a virtual processing pipeline where each step is implemented as a software service. Computing power allows instantaneous processing and lightning-fast data transfers at such a point that the concept of frame rate could completely vanish inside the data centre. On the other hand, video sequences are still captured by cameras, and content is ultimately displayed on screens. People still need to interface cloud production services with a peripheral ecosystem made of baseband video equipment. From that need emerged the concept of cloud edge equipment, which means gateways for ingesting video and audio content into the data centre, and for playing it out to some external devices. While physically connected to a pretty static video network, those edge interfaces need to fit the versatility and scalability of data centre implementations. Deltacast proposes a perfect fit to this use case with its new FLEX interfacing solutions. It allows huge channel density while consuming very few rack units, and offers unprecedented capabilities in terms of scalability and of versatility with support for many different types of technologies like SDI, HDMI and DisplayPort. In parallel, traditional broadcast equipment manufacturers are inspired by those cloud workflows and imagine new forms of multichannel, multipurpose – or repurposable – appliances based on blade servers that are equipped with video interfaces and host a series of virtualised basic features or micro- services that can be connected together to implement a higher-level function.
