Copyright

Copyright is a legal concept, enacted by most governments, that grants the creator of an original work exclusive rights to its use and distribution, usually for a limited time, with the intention of enabling the creator of intellectual wealth (e.g. the photographer of a photograph or the author of a book) to receive compensation for their work and be able to financially support themselves.

What is a dvd?

DVD (sometimes explained as "digital video disk" or "digital versatile disc") is a digital optical disc storage format, invented and developed by Philips Sony, Toshiba, and Panasonic in 1995. DVDs offer higher storage capacity than compact disc while having the same dimensions.

Before the advent of DVD in 1995, Video CD (VCD) became the first format for distributing digitally encoded films on standard 120 mm (4.7 in) optical discs. (Its predecessor, CD Video, used analog video encoding.) VCD was on the market in 1993. In the same year, two new optical disc storage formats were being developed. One was the Multimedia Compact disc (MMCD), backed by Philips and Sony, and the other was the Super Density (SD) disc, supported by Toshiba, Time Warner, Matsushita electric, Hitachi, Mitsubishi, Pioneer, Thomson, and JVC. A much earlier consumer optical disc data storage device, known as LaserDisc, was developed in the United states. The original LaserDisc technology was invented by David Paul Gregg and James Russell in 1958 and first patented in 1961, with its first public demonstration in 1972. It first came to market in Atlanta, Georgia in 1978, but used much larger discs than the later formats. Due to the high cost of players and discs, consumer adoption of LaserDisc was very low in both North America and Europe, and was not widely used anywhere outside Japan and the more affluent areas of Southeast asia, such as Hong Kong, Singapore, Malaysia and Taiwan.

Representatives from the SD camp asked IBM for advice on the file system to use for their disc, and sought support for their format for storing computer data. Alan E Bell, a researcher from IBM's  Almaden Research centre, got that request, and also learned of the MMCD development project. Wary of being caught in a repeat of the costly videotape format war between VHS and Betamax in the 1980s, he convened a group of computer industry experts, including representatives from Apple, Microsoft, Sun Microsystems, Dell, and many others. This group was referred to as the Technical Working Group, or TWG.

The TWG voted to boycott both formats unless the two camps agreed on a single, converged standard. They recruited Lou Gerstner president of IBM, to pressure the executives of the warring factions. In one significant compromise, the MMCD and SD groups agreed to adopt proposal SD 9, which specified that both layers of the dual-layered disc be read from the same side—instead of proposal SD 10, which would have created a two-sided disc that users would have to turn over. As a result, the DVD specification provided a storage capacity of 4.7 GB for a single-layered, single-sided disc and 8.5 GB for a dual-layered, single-sided disc. The DVD specification ended up similar to Toshiba and Matsushita's Super Density Disc, except for the dual-layer option (MMCD was single-sided and optionally dual-layer—whereas SD was single-layer, but optionally double-sided) and EFMplus modulation.

Philips and Sony decided that it was in their best interests to avoid another format war over their Multimedia Compact Disc, and agreed to unify with companies backing the Super Density Disc to release a single format, with technologies from both. After other compromises between MMCD and SD, the computer companies through TWG won the day, and a single format, now called DVD, was agreed upon. The TWG also collaborated with the  Optical Storage Technology Association (OSTA) on the use of their implementation of the ISO-13346 file system (known as Universal Disk Format) for use on the new DVDs.

learning compressor and creating a button

After we had learnt the basics of transferring the product to compressor we learnt how to create a button on dvd studio pro. This was fairly straight forward. This consisted of dragging the mouse across the space and creating the button. On the right hand side there was a box that came up where you could change the size, shape, the buttons job and many other things.

Introduction

In this blog I will be researching the history, copyright productions, interactive menu's, regions, different sizes and reviews of dvd menu's. I will also be blogging progress of our dvd creating progress for the Thornham project.
