As companies around the world showcased their latest developments, Display Week 2013 proved to be a good bellwether for how next-generation screen technologies were faring in the marketplace. As an extension of the trend toward higher-resolution displays, a lot of attention was focused on 4K displays, which have the same resolution as four standard 1080p HDTVs tiled together. And LG Electronics and Samsung both continued to tout their 55-inch organic light-emitting diode (OLED) television displays, which had been shown before but are now being offered for sale.

From WinZips to Cat GIFs, Jacob Ziv’s Algorithms Have Powered Decades of Compression

Lossless data compression seems a bit like a magic trick. Its cousin, lossy compression, is easier to comprehend. Lossy algorithms are used to get music into the popular MP3 format and turn a digital image into a standard JPEG file. They do this by selectively removing bits, taking what scientists know about the way we see and hear to determine which bits we'd least miss. But no one can make the case that the resulting file is a perfect replica of the original.

Not so with lossless data compression. Bits do disappear, making the data file dramatically smaller and thus easier to store and transmit. The important difference is that the bits reappear on command. It's as if the bits are rabbits in a magician's act, disappearing and then reappearing from inside a hat at the wave of a wand.
