Sony's Clever but Flawed PlayStation Copy Protection--And How They Might Have Fixed It
 
14:15
You can support this channel on Patreon! Link below The original PlayStation is a pretty neat thing. Using the CD as a storage medium was a smart move. But, Sony needed to add anti-piracy features to the disc to prevent miscreants from making bootleg copies of Crash Bandicoot. This video tells the story of how that works, why it wasn’t infallible, and also proposes a potentially impervious solution (24 years late, though). Here’s that paper on reading optical discs. It’s a good read: https://pdfs.semanticscholar.org/f772/6d20c43b22fb13f8788c8c64df2dbe9fa44f.pdf You can support this channel on Patreon! Patrons of the channel are what keep videos like this coming.

Today we are trying out a new series called Is It Safe. We're looking first at the life in Russia and if it is safe to live there. Let me know what you think of this series SUBSCRIBE TO US -► http://bit.ly/TheInfographicsShow If we do our homework well, not only will this be a good way to learn about a country we might know little about, but perhaps bust some myths regarding stereotypes, and give our viewers relevant and useful information about a place they might want to travel to someday. We picked Russia because this is the first example our viewer gave us, and it’s certainly a place that is widely discussed and possibly even mischaracterized. Today we’ll bring you all the latest statistics, see what the media is saying, and look at what Russians are saying on forums, in this episode of the Infographics Show, Is It Safe: To Live in Russia?
