Feed Description: Chirag Mehta - Tech Web Log: I discuss pretty much anything related to technology that comes to my mind, from the nitty-gritties of string parsing in some language to the overall big picture of the software world.
"TV-Links (now dead) is a site which links to sites like Google Video and YouTube, which host clips of TV shows. Today, the Gloucestershire County Council, in association with a group called the FACT, raided the sites servers and arrested the 26 year old man from Cheltenham who ran the site... This is what is known as Deep Linking (wikipedia article). There have been a few legal cases about this already in different parts of the world." - by The New Freedom blog.
The author is confusing Deep Linking with Hot Linking. Deep Linking is when you link to a web page within a site other than the home or a major section page. Hot Linking is when you embed a resource from another site on to your own site without re-hosting the media yourself. Websites like reddit and Fark deep link. TV-Links was hot linking.
I'm completely in favor of deep linking except where someone is clearly abusing your content, say by linking to detailed search results on your site by spidering every form field value. I'm in favor of hot linking provided due credit is given and single-click link to the hosting server is provided. Flickr thumbnail galleries, most video embeds, JavaScript widgets from Google including Adwords are technically hot linked but they all link to the hosting site and give them full credit.
What TV-Links failed to do was link to the appropriate YouTube, Veoh.com, and Google Video pages for the FLVs (Flash videos) they were playing on their site, within their own custom Flash video player. Since Veoh has MD5 type hash in their FLV url, there is practically no way to find the web page for a given Veoh video via it's FLV url. It's not easy for average users to find the YouTube or Google Videos page for a given video within TV-Links either. Submitters would upload a "Seinfeld" episode to Veoh and title it "DFPGDSFY4353FG" to ensure nobody can ever find it on the hosted site in a search for "Seinfeld episodes." Then they would submit it to TV-Links and correctly title it "Seinfeld Season 3, Episode 6." Veoh and YouTube/Google Videos have enough on their hands already and since we don't have good video fingerprinting technology yet, these videos would never be found pro-actively and completely ignored by the hosts.
TV-Links could have easily placed the original Veoh/Google/YouTube embeds on their site but they chose to directly hot-linked the FLVs. They reason they did this is of course to prevent copyright owners from easily finding the source of the video because then they could just as easily click the "Copyright Claim" buttons.
Copyright is a complex issue and as someone that runs a video aggregator, I feel truly sorry for the TV-Links guy. The video sites and the copyright holders both stand to lose as a result of his site. Video sites incur bandwidth, storage, and compliance costs while copyright holders could experience lower DVD sales. Music is different from TV shows. We listen to the same song 30 times. How many times will you watch the same episode of 24?
I know there was a lot of wonderful content on TV-Links but I'd say a majority of it, while being older material, nevertheless violated the rights of the copyright holders. Only reason TV-Links became so popular is because most of the videos worked as they weren't deleted immediately due to the aforementioned reasons. Why did TV-Links stay up so long? I don't know. Personally, I'd like for TV-Links to come back but if it does, what message does it send to others? That as long as you upload content illegally on server A and link to it from server B, it's acceptable?
Additional notes: There isn't an easy technical fix for the video sites to prevent the hot links as Flash details with embedded media in it's own way. Most browsers don't send the referrer when viewing embedded videos. So playing a video on Veoh.com sends the same headers to the FLV host server as watching it on TV-Links. Additionally, most browsers now prevent 3rd party cookies (so no sessions) and Flash from 3rd party hosts does not always get full privileges to access the DOM (to avoid XSS exploits). Since video sites want their embeds to play on sites like Facebook and Myspace, they pretty much have to let anyone with valid headers stream their content.
There are Flash RTMP streams and more complex content distribution network services to stream FLVs but that adds to the cost tremendously. A Flash stream server is magnitudes more expensive than a cheap lighttpd box with ample storage.
Also, it wasn't just the simple links to the illegal content that is the issue here. Like I said, he wasn't just providing a list of illegal content. He was making it viewable in his and only his site. That means you cannot go to Google to watch that episode of Seinfeld, you HAVE to watch it on his site. Thereby, his site was a very crucial component of copyright violation. Without his site, you could never find David Attenborough's Secret Life on Plants on Veoh. That goes more than just linking to illegal content
On your site, you can provide a link to 1-10-100 illegal videos on Google or YouTube. That would constitute simple deep linking to copyrighted material, which in itself is illegal but mostly tolerated when it comes to video as copyright holders can file a DMCA request with the video host to bring down the video. His site bypassed that entire mechanism for copyright holders to even file a claim. That's why they're pissed and why he was arrested. I just hope they don't try to set any examples by completely ruining his life as a warning to others.
Just quickly... Speaking as a proud now ex-MOD on tv-links i'd just like to throw my two cents in!
The majority of content we linked to was not under hidden names. Over 80% of videos were the type that few people have heard of, and as such were simply up on Stage6 or Veoh as the given name, just search for Mystery Science Theatre one Stage6. There were very few videos that remained on site under hidden names, all of which were the big shows. For instance - new heroes as h2*** whatever.. But they soon disappeared from such sites, as although Stage6, to name an example, does not have fullproof fingerprinting technology working, its not hard to find the videos if you really looked. And actually, I know GUBA have a team who manually check every video, and Veoh i beleive are in the process of implementing software to search for things like,, say the 20th Century Fox beginning.
And it would be very easy for the website involved, to locate the direct link and thus remove it from there site. In our player we stated the Host site, and for those which we did not, the host sites player was used.
What really annoys me is how easy it really is to find videos out there, tv-links was just the tip of the ice berg. AllUC.org? peekvid? OVGuide? Whats happeneing to these websites, stil seemingly untouched. And now that tv-links is gone, everybody seems to be suggesting BoxSweeper as a new alternative, any one like to guess where BoxSweeper got there links from? Yup, they stole the entire site from us, simply changing the layout! Which i suppose is a good thing, as other clone sites (tvlinkvault, tvlinksdb) will just continue with the exact same links as were now lost rfom tv-links!
Apart from that, i completely agree with you, ive got to try and work out something else to dso with my time now :P
