Electronic media

Electronic media are media that utilize electronics or electromechanical energy for the end user (audience) to access the content. This is in contrast to static media (mainly print media), which are most often created electronically, but don't require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to the general public are better known as video recordings, audio recordings, multimedia presentations, slide presentations, CD-ROM and Online Content. Most new media are in the form of digital media. However, electronic media may be in either analog or digital format.

Although the term is usually associated with content recorded on a storage medium, recordings are not required for live broadcasting and online networking.

Any equipment used in the electronic communication process (e.g. television, radio, telephone, desktop computer, game console, handheld device) may also be considered electronic media.

Electronic media are ubiquitous in most of the developed world. As of 2005, there are reports of satellite receivers being present in some of the most remote and inaccessible regions of China. Electronic media devices have found their way into all parts of modern life. The term is relevant to media ecology for studying it's impact compared to printed media and broadening the scope of understanding media beyond a simplistic aspect of media such as one delivery platform (e.g. the world wide web) aside from many other options. The term is also relevant to professional career development regarding related skill sets.

Digital Cameras

Canon has well above 1000 patented digital technologies and is seeking extended innovation each year. Most of the Canon digital cameras have a 9- point AiAF, i.e. providing true auto-focus. The screen is divided into 9 parts and the focus is captured with finesse. This is unique from the traditional 5- point auto-focusing methodology. Canon also developed the popular multi face detection technology that enables to detect up to 9 faces in its lower end digital cameras and up to 35 faces in its higher end cameras. This feature is also extended to its video shooting function. The video capturing mode has this feature extended by incorporating ‘face select and tracking’ which enables you to track a face among a crowd.

Canon’s digital SLR’s sports the ground breaking ESO technology. This technology has an integrated cleaning system which functions to remove the dust particles on the lens and on the image. It has inbuilt hardware to shake off the dust particles from the lens and software to remove the sticky dust grains from the image. Thus it aims at providing the best possible image by removing all faults. They have also initiated the anti-noise processing which takes care that no dots or white lines are formed in the image unlike other cameras which remove the noise after the image is taken which might result in distortion of the image.

Some of the highly rated Canon Digital Camera include PowerShot, IXUS and EOS. The PowerShot is aimed at the simple point and shoot user, the price is affordable and it features cameras below 10 mega pixels available in varied colour options and designs. The IXUS series is the mid-range digital camera offering that are more advanced and bit pricey. The ESO series offers digital SLR’s that are meant for professional photographers and photography enthusiasts. These SLR’s are available with different range lenses. Canon has roped in Sachin Tendulkar as their brand ambassador for marketing of their popular product line. Canon has emerged as a pioneer in its design, technology, and usability thus becoming a name synonymous to photography.

Classic iPod

The iPod classic is a portable media player marketed by Apple Inc. It is the flagship model in Apple's iPod family. To date, there have been six generations of the iPod classic, as well as a spin-off (the iPod photo) that was later re-integrated into the main classic line. All generations use a 1.8-inch hard drive for storage. The "classic" retronym was introduced with the introduction of the sixth-generation iPod classic on September 5, 2007;[1] prior to this, iPod classics were simply referred to as 'iPods'.
iPods with color displays use anti-aliased graphics and text, with sliding animations. All iPods have five buttons and the later generations (4th and above) have the buttons integrated into the click wheel — a design which gives an uncluttered, minimalist interface. The buttons are:

* Menu: to traverse backwards through the menus, and toggle the backlight on older iPods
* Center: to select a menu item
* Play / Pause: this doubles as an off switch when held
* Skip Forward / Fast Forward
* Skip Backwards / Fast Reverse
In March 2002, Apple added limited PDA-like functionality: text files can be displayed, while contacts and schedules can be viewed and synchronized with the host computer.[2] Some built-in games are available, including Brick (a clone of Breakout), Parachute, Solitaire, and Music Quiz. A firmware update released in September 2006 brought some extra features to fifth generation iPods including adjustable screen brightness, gapless playback, and downloadable games (available for purchase from the iTunes Store).

The future of Wireless Technology

The term Wireless is used for a device using electromagnetic waves for an electronic operation rather than hard wires. A wireless is generally used to transfer data on a long distance. Wireless technology is rapidly evolving theses days. Some examples where wireless systems are very common are mobile phones and pagers, navigation systems, wireless computer mouse, satellite television, portable radios, TV remote controls, wireless phones etc. Wireless can be divided into following categories: -

* Portable wireless – It includes the operation of battery-operated wireless devices or systems such as cell phones and PCS units
* fixed wireless – it includes the operation of wireless devices or systems connected to the Internet and modems
* Mobile wireless –It includes the use of wireless devices or systems in moving motor vehicles, which include the automotive cell cellular phone and computers.

Wireless systems are actually not very safe. We have some quick tips to protect your valuable data: -

1. Always use a firewall with your PC.
2. Avoid using public wireless systems for accessing your bank accounts.
3. Hide your valuable data through encryption.
4. Switch off your wireless system if you are not using it.

How a Wireless System Works A wireless microphone system converts the audio signal created by the microphone to a radio signal which is sent to the sound system by a transmitter. The radio signal is similar to those used by television and FM radio stations. At the other end the receiver converts the frequency into an audio signal.

Future of wireless systems: - The LTE (Long Term Evolution) technology is gaining momentum these days which says improving standards of mobile phone to cope up with future technological requirements by reducing cost and improving efficiency.Many officials like telephone companies, technology firms, mobile phone makers, industrialists are using wireless technology systems
