Purpose of digital media

Music

Common digital music formats include WAV and MP3.

MP3 files allow digital files to be downloaded from the internet.

MP3s can be created by converting WAV format CDs (which usually contain 10-15 songs) and reduce to smaller file sizes

iTunes, WinAmp etc., are software programs that not only play CDs, but convert them to MP3

You can get hundreds of MP3 songs on a CD.

The report, Piracy on the High Cs, was compiled by University of Pennsylvania professors Rafael Rob and Joel Waldfogel.

It asked the students about the albums they bought and those they downloaded without paying. The students obtained 1,209 albums when downloading was available.

They purchased 617, while a further 592 were downloaded.

Music

The ease of converting a CD song to MP3 has given rise to ‘piracy’.

Piracy is the illegal copying, sharing and selling of digital data, for which you have not paid the owner of the music for.

Piracy affects the income of the music industry

Piracy is at epidemic levels as it is so easy to copy, email, download and share.

Music Piracy

Online music piracy has had serious effects on the music industry.

Online music piracy has caused some record stores sales to drop by 20% every year.

Online music piracy is responsible for 2.6 billion downloads of copyrighted files every month! (source bbc: clickonline, 06/06)

Live Music

The rise of sharing MP3s and the size of the problem has forced the music industry to re-think how it ‘makes money’

Steaming Music – choose a song and listen live (but you can’t keep it)

This is a Joystick

A joystick is a personal computer peripheral or general control device consisting of a handheld stick that pivots about one end and transmits its angle in two or three dimensions to a computer. Most joysticks are two-dimensional, having two axes of movement (similar to a mouse)

1980s Joystick

HISTORYThe ‘joystick’ – as an electronic control device was developed at the end of WW2 by a team on the German rocket program was developing the Wasserfall missile, a successor to the V-2 rocket, the first ground-to-air missile intended for shooting down enemy aircraft. The Wasserfall steering equipment converted the electrical signal to radio signals and transmitted these to the missile.

Joystick – comes from a name, Mr. A.E. George who pioneered early flight – the George Stick

Military Applications are OFTEN the first use of TECHNOLOGY in computing.

How they work and history

Standard 9 pin joystick controller is still present on most home PCs, though USB is now the most common method of connecting.

GAME CONTROLLERS(Not Joysticks!)
