Abstract
A method and system for delivering a live feed to a client is provided. According to one aspect of the invention, content data is generated by an encoder. Tag data that indicates locations of video frame data within the content data is generated while the content data is being generated. According to one embodiment, the tag data is generated by the encoder. According to an alternative embodiment, the tag data is generated by parsing the content data. The content data is at a location from which the content data is delivered to the client. The tag data is stored at a location from which the tag data may be used to provide the client non-sequential access to the content data. Before the encoder finishes generating the content data, a request is received for non-sequential access to the content data by the client, second content data is constructed based on the content data, the tag data and the request for non-sequential access, and the second content data is sent to the client.
