Abstract:
1. A method for performing a seek operation in a media stream displayed on a playback device, comprising: receiving a media stream from a network, the media stream being associated with a first bit rate and including a plurality of fragments; receiving a user request to seek to a new location in the media stream; using the new location to determine a corresponding network address of one of the plurality of fragments in the media stream; in response to the user request, downloading the media stream, associated with a second bit rate that is less than the first bit rate, from substantially the new location to ensure fast start-up by using the network address in the media stream, wherein the content of the media stream is identical at the first and second bit rates, but quality increases with higher bit rates; rendering the media stream starting at the new location; and ramping-up the bit rate of the media stream after the fast start-up based on a previously stored network bandwidth.
