An IP-based broadcast media network not only comprises a number of devices in different locations but relies on several technical components to ensure everything being networked connects and interacts correctly.
Today’s media systems are comprised of countless moving parts. Whether it’s live production, playout, traditional delivery, or OTT distribution. Today’s infrastructures are more complex and sophisticated than ever due to multiple formats and transport protocols, the migration to IP and the emergence of pure software-based systems.
A waveform monitor reveals more technical image nuances than most people can see on average video picture displays.
In Part 1 we looked at how TDM provides a compromise to deliver the flexibility and scalability of IP, while at the same time providing the ease of use of SDI. In this article, we look at how TDM deals with latency and frame accurate timing.
Although virtual sets and even Augmented Reality (AR) have been around for decades now, the concept has evolved with the arrival of new display technologies like LED videowalls, which provide alternatives to traditional chroma keying.
Broadcast service providers providing live production, contribution, playout and transmission services have observed the continuous and accelerating movement towards OTT services.
The U.S. Postal Service’s unofficial motto applies just as much to ENG crews as to mail carriers: “Neither snow nor rain nor heat nor gloom of night” will keep these dedicated professionals from their appointed tasks.
Modularity is essential for the design of scalable and flexible services and applications. We can define services as modular units that implement specific business functionality. Focusing on a single functionality, modular services can be easily reused in various contexts and can also be used as building blocks to meet new requirements. In addition, the modularity in the services prevents the propagation of changes to other services and therefore simplifies their maintenance.
