Reading and writing is much faster with digital media , and also thanks to their digital nature, they can utilize interactive menus and file structures.
On top of all that, DVDs are much cheaper to produce and distribute than most analog media. Despite their high-tech nature, the actual operation of optical digital media hearkens back to the earliest of sound reproduction machines, the phonograph. Instead of a needle sliding along a grooved surface and creating physical vibrations, however, optical storage is read by a laser moving across a track of printed depressions in the disc's written surface.
This surface is made of a very thin sheet of aluminum pressed between layers of plastic and acrylic. Digital data is transmitted in binary, a number system that uses only 1s and 0s. CDs, DVDs, and Blu-rays are made with a series of microscopic laser-etched pits and lands in the aluminum. Consecutive, matching types of indentations such as a pit following a pit signify a zero, while a switch from pit to land or back denotes a one. As the disc spins above the laser, these 1s and 0s are sent to a controller in the drive and organized for delivery to a video processor.
At this point, home theater setup moves farther away from antiquated analog technology than ever. Even if you weren't around for the VCR craze , you've probably poked your head behind an entertainment center and been treated to a proverbial rat's nest of cables.
This ubiquitous mess of cable has been a part of video and audio electronics since movies and television became such important American hobbies.
After all, hardwired systems have been the most readily available since home electronics was born. But corded setups do have drawbacks. Cables, themselves, can be prone to signal bleed and shorted connections. Troubleshooting a bad HDMI connection could mean crawling behind your big-screen TV and checking each individual plug. Speaking of maneuvering between an appliance and the wall, it's not always easy or even possible to snake a wire around a tight corner.
And, in light of America's growing obsession with digital video, it's nearly unthinkable to distribute one high-definition video signal throughout an entire house using a series of HDMI cables and adapters. In order to solve the widespread problem of cable clutter, it makes sense to look to another massively popular digital standard : wireless networks. Far removed from the first days of As wireless technology has progressed during its short life, it's been worked into a large number of home devices, and televisions are no exception.
As you might imagine, the act of transmitting high-definition video data through the airwaves isn't exactly simple. As with so many advanced technologies, there are a few different methods through which home devices pull signals from thin air. Most homes have a Wi-Fi router that they use to browse the internet.
Some portable video players are set up to utilize these same home setups to deliver a video feed to any device on the network. Other units use proprietary broadcast languages to send video over the air to specifically paired devices. Both of those types of wireless video players are restricted to the moderate speeds of home Wi-Fi. Because of the huge amount of bandwidth needed to accommodate a raw video feed, transmissions over standard wireless networks often use some kind of compression to make the files smaller.
