High-Quality Video

The techniques I described in my previous post are quickly becoming outdated as they mostly use flash embedded videos. There are several problems with this method of delivery;
  • they are usually fairly poor quality and sometimes the sound goes hugely out of sync
  • depending on the website they may take hours to load which defeats the whole object of streaming
  • they can only be watched once, unless you have a program to save them with (such as the VideoDownloader plugin for firefox) and even then it is not usually worth the effort
DivX, the company behind one of the most widely-used video compression techniques have created a website and embedded web DivX players called Stage6. This requires the users to upload videos in the DivX format, which has proved to be incredibly popular as the encoded videos are much, much smaller than raw footage so means that users can upload videos that are much higher quality, sometimes rivalling DVD quality. The stream is almost always instant, providing you have a good enough connection as DivX has obviously invested a lot of money to provide high bandwidth. Every video on the site has the option to be saved to the computer after streaming.

Streaming Video

there are many ways to watch copyrighted material on the internet, whether it is a tv show, movie or a music video you can find pretty much anything out there if you look hard enough and have enough time. One of the increasingly popular ways of distributing material is to 'stream' it from a website. Since the growth of ADSL, more and more people at home have the capabilities to stream video, the most popular website for this is YouTube.

YouTube are part of a multi-million pound company, so they have a lot to lose if they neglect their responsibilities as a video-hosting website. This means that it would be extremely difficult to find copyrighted material on there as they have numerous measures to prevent this, such as people to trawl forums and the website itself for any such material and only allowing users to upload 10 minute videos unless they have a special membership. Despite this, YouTube and other similar video hosting sites still have copyrighted videos on them, and always will.

How do these films get below the radar? The user often posts them under completely different names to what they actually are, or use a code for the title, for example if they were to post the 3rd episode from the 5th series of The Simpsons they may put "TS S05E03" or something similar, that way people searching YouTube for The Simpsons will never return the result they are looking for.

The user still has to have some way of finding these files though, so that is where 3rd party websites and forums start to appear, such as the recently deceased tv-links.co.uk. Moderators and contributers to these sites search the web and other forums for direct links to episodes and films, then simply list the links in their website. In theory this is taking advantage of a loophole in the system, as they are not actually hosting the videos, so are not liable. The same excuse that torrent websites use, which i will look at later on.

Documenting the date of creation

The easiest way to ensure your work isnt used by somebody else is to send your work to yourself by recorded, postdated delivery and keep the package sealed once you receive it. This isn't an official copyright but simply a way to prove that you owned the original piece at a certain point in time in case an ownership issue is taken to court.

Copyright and Photography

If you would like to commission a photographer to take pictures of your work, you need to clearly specify who owns the rights to the image beforehand. By default the photographer owns the copyright to any picture they take although they need your permission to reproduce it if the sole subject is your work, the exception to this is if the subject is something else and your work happens to be in the photograph.

International Copyright Law

The laws of the country apply when using copyrighted items as each have their own patent office, for example Cadburys chocolate have copyrighted the purple colour of their packaging, but cannot use it in Australia as another chocolate company uses a similar colour for theirs

Areas of copyright

There are four main areas of intellectual property rights:

Copyright For Material

Literary and artistic material, music, films, sound recordings and broadcasts, software and multimedia

Design Rights

You can have registered and unregistered design rights for designs and drawings

Trademarks

If a product is similar to another they can be confused. For example if an inferior product imitates a quality one with similar packaging, or a company uses a similar colour scheme or logo (see Orange vs EasyJet case)

Patents

Protects a physical invention
