Method and apparatus for streaming multimedia data with access point positioning information

A system for processing multimedia data streamed over a network, comprising a client device that includes a processor and a memory that stores instructions, that when executed by the processor causes the processor to:

• download, by the client device, a playlist file for a multimedia presentation over the network from a streaming server using a transfer protocol, the playlist file including an ordered list of Universal Resource Indicators (URIs) for a plurality of media files, each of the plurality of media files including compressed video data corresponding to a segment of the multimedia presentation and containing reference frames;
• download, by the client device, a data file that is associated with the playlist file, the data file including, for each of a plurality of reference frames included in the respective media file from the plurality of media files, respective reference frame information indicating a respective location in the respective media file of the each of the plurality of reference frames;
• perform, responsive to a user request, a trick play related to a displaying of the multimedia presentation, using one or more reference frames from the plurality of reference frames;
• select, from a plurality of variant streams, a first variant stream for use in displaying the multimedia presentation;
• and
• reassemble segments included in media files associated with a first variant stream of the plurality of variant streams to play the multimedia presentation as a continuous stream.

• selecting, from a plurality of variant streams, a first variant stream for use in displaying the multimedia presentation;
• reassembling segments included in the plurality of media files associated with the selected first variant stream to display the multimedia presentation as a continuous stream;
• and
• switching between the selected first variant stream and a second variant stream by aligning first reference frames of the selected first variant stream and second reference frames of the second variant stream based on respective time stamps of the first reference frames and the second reference frames, the respective timestamps being included in a first data file associated with the selected first variant stream and a second data file associated with the second variant stream.
