  • accepting a speed designation at a network client from a human user;

    a network server selecting a composite media stream of a plurality of composite media streams to be rendered at the network client, each of the plurality of composite media streams corresponding to the same multimedia content and having timelines modified by different degrees, the selected composite media stream having a modified timeline most closely matching the speed designation, the selected composite media stream having a plurality of individual media streams representing the multimedia content, at least one of the individual media streams comprising an audio stream representing audio content having an original pitch, the individual media streams having timelines that are synchronized with each other;

    streaming the composite media stream from the network server to the network client;

    modifying, at the network client, the timelines of the individual media streams in accordance with the speed designation while keeping the timelines synchronized regardless of the speed designation and while maintaining the original pitch of the audio content;

    rendering the composite media stream at the network client in accordance with the modified timelines of the individual media streams; and

    wherein the plurality of composite media streams include multiple composite media streams corresponding to the same multimedia content and having the same degree of timeline modification but different degrees of quality, and wherein the selecting the composite media stream further comprises determining an available bandwidth between the network server and the network client and selecting the composite media stream that provides the best quality while requiring no more than the available bandwidth.
