A playlist file for a selected multimedia presentation is downloaded by a client device over the network from a streaming server using a transfer protocol. The playlist file provides a list of URIs for media files each providing compressed video data corresponding to a segment of the multimedia presentation. The compressed video data includes reference frames used for video compression. A data file that is associated with the playlist file is also downloaded by the client device over the network from the streaming server using a transfer protocol and provides information identifying a location, a size, and a time stamp for each the reference frames contained in the media files listed by the playlist file. This information can be used by the client device to perform trick plays and to switch and stitch between variant streams."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for streaming multimedia data with access point positioning information","description":"A method and apparatus for streaming multimedia data over a network is provided.
