Abstract

Media fragmentation may be provided. First, a request for a manifest may be received from a client. Then, in response to the received request for the manifest, the manifest may be sent to the client. Next, a request may be received from the client for a file fragment. The request may indicate a start time and an end time corresponding to the file fragment. The request may be in a format defined by the manifest. Then a lookup table may be queried for a first byte location in a media file corresponding to the start time and a second byte location in the media file corresponding to the end time. Next, a portion of the media file between the first byte location and the second byte location may be extracted from the media file. The portion may comprise the file fragment. The file fragment may be sent to the client.
