Streaming Media - From plain old transmission control protocol (TCP) to newly conceived protocols, the variety of methods for delivering video across the internet is a key area of interest for the entire streaming media industry. After all, what good is the best-quality capture and compression if the delivery method can't keep pace?
Back in January, in an article called “Latency Sucks!” that dealt with lowering the overall delivery time of interactive or streaming video, we touched on a few newer transmission protocol derivatives: web real-time communication (WebRTC), reliable user datagram protocol (UDP), and plain old real-time protocol (RTP). Lower latency typically equates with lower-quality compression, based on the assumption that the longer the time given to processors to compress a video image, the better the quality. In this article, we will take a deeper look at the underlying protocols and discuss which ones make sense for particular applications. While the underpinnings of over-the-top (OTT) live linear delivery rely on a tried-and-true protocol, TCP, there are actually numerous technologies available to the streaming media professional.
With an eye on lowering latency and increasing reliability, while playing nicely with the neighbors— neighboring packets and networking gear—let’s now explore alternate transmission protocols that expand on or replace TCP as the reigning streaming transmission champ.
Danish University And Industry Work Together On Open Science Platform Whose Results Will All Be Patent-FreeAugust 15, 2017
TechDirt - Here on Techdirt, we write a lot about patents. Mostly, it's about their huge downsides -- the stupid patents that should never have been awarded, or the parasitic patent trolls that feed off companies doing innovative work. The obvious solution is to get rid of patents, but the idea is always met with howls of derision, as if the entire system of today's research and development would collapse, and a new dark age would be upon us. It's hard to refute that claim with evidence to the contrary because most people -- other than a few brave souls like Elon Musk -- are reluctant to find out what happens if they don't cling to patents. Against that background, it's great to see Aarhus University in Denmark announce a new open science initiative that will eschew patents on researchers' work completely:
The platform has been established with funds from the Danish Industry Foundation and it combines basic research with industrial innovation in a completely new way, ensuring that industry and the universities get greater benefit from each other's knowledge and technology.
University researchers and companies collaborate across the board to create fundamental new knowledge that is constantly made available to everyone -- and which nobody may patent. On the contrary, everyone is subsequently freely able to use the knowledge to develop and patent their own unique products.
According to Aarhus University, Danish industry loves it: Read more...
The Telegraph - Why you should stress-test your small business’s IT protections.
Hire a security company, install the right protections, backup all your data – these may sound like the key steps to securing your SME (small or medium-sized enterprise), but you’ve missed one step: testing your systems to make sure that they actually perform as they should.
That’s the idea behind stress testing. A survey by PolicyBee, a cyber insurance firm, revealed that only 14pc of SMEs have tested their cyber-attack response plans. Stress testing generally refers to the search for weak points in your IT setup, whether it’s the level of traffic that servers can withstand or trialling your backups to ensure that you can actually recover data following an attack.
The Bank of England runs so-called "war games" to test the security resilience of British banks, with Operation Waking Shark and Waking Shark II involving live attacks to stress test how banks and their
staff respond. The idea is catching on, with European Union officials considering a similar exercise on the continent.
At a company level, that’s one example of what such tests could involve, though what your business requires will depend on its size, sector
and what security risks it faces – what the security industry calls your "threat model".
The Register - The UK’s Open Data Institute is offering up £60,000 for a company to make it easier for organisations to create collaborative data registers.
Registers – authoritative datasets usually used as core reference information – are increasingly becoming a major part of many nation’s data infrastructure.
But they often need to involve a lot of organisations and individuals – an address register could need input from local authorities, postal services and citizens, for instance.
According to the ODI – the brainchild of web founder Tim Berners-Lee and high-profile computing boffin Nigel Shadbolt – having so many stakeholders can end up causing management headaches and confusion for users.
ZDNet - Organisations that provide critical national infrastructure services including electricity, water, energy, transport, and healthcare could face fines of £17m or four percent of their global turnover if they fail to protect themselves from cyberattacks.
The plan is being considered by the UK government as it examines how to implement the European Union's Network and Information Systems (NIS) Directive from May 2018. The directive represents the first piece of EU-wide legislation on cybersecurity and provides legal measures in an effort to protect member states and their essential services from cyberattacks.
This consultation on protecting essential services comes a few months after parts of the National Health Service were crippled -- in some case for over a week -- by the global WannaCry ransomware outbreak.
