Swisscom Broadcast is adding the latest IP-based platform from Net Insight to expand its core media network. The Swiss company offers a wide range of audio and video services and operates national contribution and distribution networks based on Net Insight’s Nimbra all-IP media transport platform.
Streaming wars are associated in the public mind with the intensifying battle for supremacy between Netflix, Amazon, Disney, Apple and a few others in the SVoD (Subscription VoD) field, but it also applies to the contention heating up between underlying protocols for low latency transmission of video over the Internet.
Barnfind participated in the construction of the signal transmission network and was also responsible for the transmission of all signals between all sites.
At one time the only repeatable source of light on Earth was the sun. Later it was found that if bodies were made hot enough, they would radiate light. Any treatment of illumination has to start with the radiation from heated bodies.
Internet packets can be occasionally dropped, primarily due to instantaneous congestion in routers. Dropped packets need to be recovered for glitch-free video. Given enough time, any losses can be recovered, but contribution applications are typically latency-sensitive and can not ‘wait forever’.
V-Nova has become a new member of the Advanced Television Systems Committee (ATSC), where it will help promote and contribute to the emerging ATSC 3.0 specification for digital terrestrial broadcasting worldwide. The company said that intelligent media compression is core to delivering new ATSC 3.0 services.
As broadcasters accelerate IP migration, we must move from a position of theory to that of practical application. Hybrid solutions to integrate SDI, AES, MADI, and IP will be needed for many years to come, even with green field sites, as broadcasters seek a steady and methodical transition.
Many protocol specifications are used today to reliably transport compressed video over IP networks and the internet. New transport specifications such as RIST with ARQ continue development and testing.
