Abstract: Methods, apparatus and systems for processing and tagging at least a portion of a video with metadata are provided herein. In some embodiments, a method for processing and tagging at least a portion of a video with metadata includes extracting a plurality of frames from the video, generating a fingerprint for each frame of the plurality of frames, or for a set of frames of the plurality of frames, determining contextual data within at least one frame or set of frames, associating the generated fingerprint of each frame or set of frames with the determined contextual data, and storing the association of the fingerprint of each frame or set of frames and the contextual data.

Abstract: A method of distributing electronic audio or video content from a distributing computer system to a user device (such as a computer, PDA or mobile telephone) over a telecommunications network, comprising: the distributing computer system detecting at least one characteristic of the user device, the distributing computer system selecting a version of the content according to the characteristic, and the distributing computer system transmitting to the user device the selected version of the content. The invention also provides a method of processing electronic content comprising: encoding the content with programming code indicative of playback preferences, for facilitating preloading of the content, for detecting at least one characteristic of a user device or a communications link thereto, or any combination of these. The programming code may be inserted automatically or manually, and may comprise a link.
