Digital media stream audio/video processor
Digital media is a electronic media where digital data can be stored as in digital form. Technical aspect of storage and transmission of digital video, augmented reality and/or digital art of information can also be refer by digital media. The some common examples of digital media ( based on technical view ) are as follows:
- Televisions
- Internet
- Video games
- Cellular phones
- Compact discs
- Computers
- Digital video
- Game consoles
- Electronic books

In order to convert data from analogue to digital, digital media use a device called Analogue-to-digital converter or ADC, which is an electronic device that converts an input analogue voltage to a digital number proportional to the magnitude of the voltage. Some of the non/partially electronic devices can be considered as ADCs. And the output of the digital media are using a different coding schemes such as, binary number and Gray code for encoding data.
Computer hardware and software can be used to processed the data of digital media. ASIC high performance digital hardware device is used in order to get a high performance processing. Editing, filtering and content creation is a part of processing.
The goal of DSP is used to measure, filter, edit, and/or compress continuous real world analogue signals. The first step is to convert the signal from an analogue to a digital form, by sampling it using an analogue to digital converter ( ADC ). Then, ADC turns the analogue signal into a stream of numbers. The required output signal is another analogue output signal, which requires a digital to analogue converter ( DCA ). Although this process is more complex than analogue processing and has a discrete value range, the application or computational power to digital signal processing allows for many advantages over analogue processing in many different applications. Error detection and correction in transmission as well as data compression are some of the example of DCA.

Computers played a role in production or display of artwork and that is digital art. This art could be image, sound, animation, video, video game, website, and gallery installation. By using digital technologies, the lines between traditional works of art and new media works created using computers has been blurred. So that, an artist may combine traditional painting with algorithm art and other digital techniques and often, the medium itself is considered the artwork. And Because of this effect, sometime defining computer art by its end product can be difficult. Digital artists do same as traditional artists have done by exploring and adopting a culture’s new technology towards the making of a personal imagery. Digital art is created and stored in a non material form on the computer’s memory systems and must be made physical, in the form of prints on a paper or some other forms of printing version. Additionally, digital art can be exchanged directly to a computer screen in gallery situations in every where in the world around the web.
Even though digital media are considered as a “ green “ product by reducing the paper waste, but the heavy metals side which is used to make the components are not environment friendly unless recycled it in a right manner.
