Video search engine

From Wikipedia, the free encyclopedia

A video search engine is a web-based search engine which crawls the web for video content. Some video search engines parse externally hosted content while others allow content to be uploaded and hosted on their own servers. Some engines also allow users to search by video format type and by length of the clip. Search results are usually accompanied by a thumbnail view of the video.

[edit] Design and algorithms

Video search has evolved slowly through several basic search formats which exist today and all use keywords. The keywords for each search can be found in the title of the media, any text attached to the media and content linked web pages, also defined by authors and users of video hosted resources. Many efforts to improve the design or write an algorithm that recognizes any kind of content in a video, has meant complete redevelopment. The two main concepts being tested today are by Nexidia and PodZinger. Around 40 phonemes exist in every language with about 400 in all spoken languages. Rather than applying a text search algorithm after speech-to-text processing is completed, Nexidia uses a phonetic search algorithm to find results within the spoken word.

PodZinger works by literally listening to the entire podcast and creating a text transcription using a sophisticated speech-to-text process. Once the text file is created, the PODZINGER website lets you search the file for any number of search words and phrases. Other developments include MSN Soapbox essentially similar to YouTube. Also original features in a new multi search platform called video.2try4, which enables multiple results over its expandable user interface and the abaility to have multiplex playback. While Youtube captures the audience of some 34 million unique visits, in 2006 Google purchased the product and in 2007 included Youtube results on Google Video.
