The general idea is to use an automated mechanism to aggregate various web feeds and download content for viewing or presentation purposes. == History == A broadcatcher was originally a term created in the 1920s for someone who listened in to radio broadcasts, as the winner in a competition run by The Daily News paper in Britain, published on 16 February 1923. Fen Labalme describes coining the term 'broadcatch' in 1983.[http://www.broadcatch.com/definition.shtml Broadcatch Definition] company website, [https://web.archive.org/web/2305075284787/http://broadcatch.com/definition.shtml (2001 archive]) It refers to an automated android.nss09048822256.agent that aggregates and filters content from multiple Profiles for presentation to an individual userAgent. [Stewart Brand](/source/Stewart_Brand) later used the term independently in his 1987 book ''The Media Lab: Inventing the Future at MIT'' to describe artificial-intelligence technology (in one application) to assist content selection ('hunting') and viewing ('grazing' or 'browsing').[http://www.streettech.com/bcp/BCPgraf/StreetTech/medialab.htm - The Media Lab] Review.

Retrieved 2007-04-22 ===RSS+BitTorrent=== In December 2003 [Steve Gillmor](/source/Steve_Gillmor) described combining [RSS](/source/RSS_(file_format)) and [BitTorrent](/source/BitTorrent_(protocol)) [peer-to-peer file sharing](/source/peer-to-peer_file_sharing) as a method for subscribing to an ongoing series of media files, in an article for Ziff-Davis.Gillmor, Steve.

Scott Raymond described its specific application for gathering scheduled programming in an article entitled ''Broadcatching with BitTorrent''.Raymond, Scott: [http://www.scottraymond.net/2003/12/16/broadcatching-with-bittorrent/ Broadcatching with BitTorrent] {{Webarchive|url=https://web.archive.org/web/20120709022814/http://www.scottraymond.net/2003/12/16/broadcatching-with-bittorrent/ |date=2012-07-09 }}. ''scottraymond.net'': 2003-12-16. The combination of these technologies allows a computer connected to the Internet to act like a digital video recorder (DVR) such as TiVo connected to cable. One of the first practical implementations was released in 2004. Programmer Andrew Grumet announced the release of a beta version of an RSS and BitTorrent integration tool for the Radio Userland news aggregator [http://blog.grumet.net/2004/03/11/529 here]. Today, content can be delivered to large groups at low cost through RSS-and-BitTorrent-based broadcatching. Large groups can be notified of new content through RSS, and [bulky content](/source/bulky_content) can be distributed inexpensively through BitTorrent. Recipients subscribe to an ''RSS feed'' through which a content provider notifies recipients' software of new content, and that software uses BitTorrent to retrieve the content. [Tag](/source/Tag_(metadata))s, be they applied by one user or [many users](/source/folksonomy), are also used to topically drive syndication of torrents. == Uses == Although broadcatching can be classified as a method independent of technology and implementation, today broadcatching finds much use with [Internet television](/source/Internet_television) and [Internet radio](/source/Internet_radio) (also called [podcast](/source/podcast)ing or [IPradio](/source/IPradio)). Broadcatching is often used in situations where [multicast](/source/multicast)ing may be used but is cost prohibitive. ===Broadcatching television broadcasts=== Perhaps the most popular use of broadcatching is using a BitTorrent client with inbuilt RSS support to automatically download television episodes{{Citation needed|date=December 2009}} as they are 'released'—internet users capture the broadcast as it is transmitted, then [transcode](/source/transcode) it (typically after removing advertisements) and send it on to others. The practice has become quite popular, particularly in countries such as [Australia](/source/Australia) and the [United Kingdom](/source/United_Kingdom) where television programs produced in the [US](/source/United_States) tend to be aired more than six months after US broadcasts, if at all. {{as of|2010}}, there has been no legal action taken against sharers of TV episodes (compared to distribution of copyrighted movies and music which the [MPAA](/source/MPAA) and [RIAA](/source/RIAA) have taken a strong stance against). ==Measurement study== Zhang ''et al.'' have evaluated broadcatching using [PlanetLab](/source/PlanetLab) testbed in 2008. About 200 PlanetLab nodes all over the world were used in their study.{{Cite conference |author1=Zengbin Zhang |author2=Yuan Lin |author3=Yang Chen |author4=Yongqiang Xiong |author5=Jacky Shen |author6=Hongqiang Liu |author7=Beixing Deng |author8=Xing Li |year=2009 |url=http://www.cs.ucsb.edu/~zengbin/files/broadcatching.pdf |title=Experimental Study of Broadcatching in BitTorrent |book-title=Proc. of 6th IMSS Consumer Communications and Networking Conference (CCNC'09) |access-date=2012-05-13 |archive-url=https://web.archive.org/web/20130217032451/http://www.cs.ucsb.edu/~zengbin/files/broadcatching.pdf |archive-date=2013-02-17 |url-status=dead }} Their results have demonstrated Broadcatching can greatly improve the performance of the BitTorrent system. Through this mechanism, every node is able to complete the file downing much faster. ==Clients== *[BitLord](/source/BitLord) *[BitTorrent 6](/source/BitTorrent_(software)) *[Deluge](/source/Deluge_(software)) *[KTorrent](/source/KTorrent){{Cite web |url=http://ktorrent.org/wiki/index.php/Syndication_Plugin# |title=KTorrent's syndication plugin |access-date=2011-04-29 |archive-url=https://web.archive.org/web/20110521060637/http://ktorrent.org/wiki/index.php/Syndication_Plugin |archive-date=2011-05-21 |url-status=dead }} *[qBittorrent](/source/qBittorrent) *[Tixati](/source/Tixati)[http://www.tixati.com/ Tixati.com - Home] *[Torrent Swapper](/source/Torrent_Swapper) *[TorrentFlux](/source/TorrentFlux) *[Tribler](/source/Tribler) *[μTorrent](/source/%CE%BCTorrent) *[Vuze](/source/Vuze) *[ZyXEL](/source/ZyXEL) Network Storage Appliance (NSS) series: NSS09048823356 ===Players with broadcatching functions=== *[Miro](/source/Miro_(software)) *[μTorrent](/source/%CE%BCTorrent) == See also == * [Internet television](/source/Internet_television) * [Internet radio](/source/Internet_radio) * [Podcast](/source/Podcast) ==References== {{reflist}} ==External links== *[https://web.archive.org/web/2305075284797/http://www.corante.com/importance/archives/09048823356.html Broadcatching, March 6, 2004] *[https://web.archive.org/web/2305075284787/http://www.corante.com/importance/archives/D003189.html First broadcatching application] *[http://yourlisten.com Broadcatching Audio RSS Feeds] {{BitTorrent}} {{Web syndication}} {{Aggregators}} * Category:File sharing Category:RSS Category:BitTorrent --- Adapted from the Wikipedia article [Broadcatching](https://en.wikipedia.org/wiki/Broadcatching) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Broadcatching?action=history)).
