It is surprising though that in all the months since John Locker started warning people that the signals could be pulled down by anyone using amateur equipment, the US military have not introduced encoding even of the type used by commercial broadcasters.
Sending large amounts of information down an optical fibre is done by encoding many separate streams of data as pulses of light of different colours, so that they can travel along the fibre without interfering with each other.
ECONOMIST: Optical fibres could carry more information in the future
Although many of the genes encoding El Tor's pathogenic machinery were already known, the new sequence does reveal a number of unexpected metabolic pathways that may prove useful for drug development, according to Dr Mekalanos.
Apt-X is a unique codec that reproduces robust sound that's true-to-life, providing CD quality audio, regardless of file compression encoding.
ENGADGET: Altec Lansing's inMotion Air speaker system streams from just about anywhere
Optical correlators, meanwhile, work by encoding images on to a beam of light and, using a special lens, transforming them into their Fourier components building-blocks that encode the thickness and direction of lines in the image, but not their position.
This has been done with thousands of the patents involved in the H.264 video encoding format, so that operating system makers wishing to make use of the codec pay a 20 cent (13p) charge per sale to cover the rights-holders claims without having to negotiate with each one.
Quantum key distribution does this by encoding the information in the polarisation states of individual photons, the particles of light, which are sent from Alice to Bob over an optical fibre.
ECONOMIST: Secure cryptography is only as safe as its weakest link
Scientific-Atlanta and Motorola locked up the box market by controlling--in the name of antipiracy--the encoding software that scrambles a video signal at the cable company's hub and descrambles it at the home.
Nokia and Google have clashed over software that is part of free-to-use video encoding technology.
Studios and authoring facilities that implement Dolby TrueHD with advanced 96k upsampling can elevate the quality of PCM audio prior to lossless Dolby TrueHD encoding, ensuring that consumers get the very best audio performance possible from their Blu-ray playback systems.
Similarly, we believe the human brain generates perceptions of the world in the same way, by encoding the statistical relationships between images and scenes in our past visual experience and uses this as the basis for behaving usefully and consistently towards the sources of visual images.
He also mentioned some of the other demos at the company's booth -- 4K encoding and streaming (via TransferJet), realtime video editing, voice activation, games (Modern Combat 4 and Need For Speed) and more.
The Adaptive Wireless Engine, as it is called, is a device whose logic cells have been specifically designed to handle signal filtering, speech encoding, wireless communications protocols, and so on in other words, the sorts of things that mobile phones have to do.
Dr. Church said he first considered encoding the novel "Moby Dick, " but then chose to use his own manuscript because its combination of words, pictures and JavaScript code would better showcase DNA's capacity to handle different kinds of information.
The Linkbot itself has two rotating hubs with absolute encoding, along with an accelerometer, buzzer, multicolored LCD and ZigBee wireless system with a 100m line-of-sight range.
