The power and flexibility of cloud computing is being felt by broadcasters throughout the world. Scaling delivers incredible resource and the levels of resilience available from international public cloud vendors is truly eye watering. It’s difficult to see how any broadcaster would run out of computing power or storage, even with 4K and 8K infrastructures.
Most live remote outside broadcasts are thoroughly planned by producers and directors who are often too busy to consider potential equipment problems. Technology is an engineering responsibility. Engineers must be ready for any circumstances that threaten to take the show off-script or off-air, from dead wireless mic batteries to unexpected foul weather. In live TV, anything can happen and probably will, usually at the worst possible time.
Time base correction is an enabling technology that crops up everywhere; not just in broadcasting.
Digital audio interfaces were developed as a way of avoiding generation loss between devices.
The Need For Sync - In any audio environment where multiple pieces of equipment are being used together, it is imperative that they are synchronized. If they do not run in time with each other it will be difficult - if not impossible - to produce a coherent end result where everything fits where it is supposed to.
The last twenty years has seen a lot of film and TV hardware turn into software that runs on workstations and servers. With Apple’s move away from Intel, though, and several other recent attempts to popularize alternative designs, anyone looking at new equipment finds a field in flux.
As broadcast facilities and other organizations that use media to educate and inform continue to carefully make the move to video over IP, they currently face two main options, with a range of others in the wings. They may opt for a full SMPTE ST 2110 design that leverages uncompressed pristine quality video for higher profile productions or lightly compressed NDI networking, which brings with it less costs and easy access to an expanding ecosystem of compliant products and systems.
“You need to be very predictable with the broadcast at all times. When I started doing this you had to be really careful with 5.1; there was no standardization,” he says. Indeed, for a long time, as broadcasters began to switch to HDTV across the U.S., it was not unusual for audio channels to be mixed up during transmission, or for audio processors to be incorrectly set or configured.
