  • ASSEMBLING STREAMED CONTENT FOR ON-DEMAND PRESENTATION

    Issued US 20110106847

    Assembling streamed content for on-demand presentation is described. In embodiments, a media asset can be requested from a content distributor, and cacheable segments of the media asset are streamed to the requesting client device. The cacheable segments are received in an initial quality display format for uninterrupted playback of the media asset at the client device while the cacheable segments are being received. An asset matrix that correlates a bit rate and a time position for each…

    Assembling streamed content for on-demand presentation is described. In embodiments, a media asset can be requested from a content distributor, and cacheable segments of the media asset are streamed to the requesting client device. The cacheable segments are received in an initial quality display format for uninterrupted playback of the media asset at the client device while the cacheable segments are being received. An asset matrix that correlates a bit rate and a time position for each cacheable segment in the media asset is also received. The cacheable segments of the media asset can be assembled according to the asset matrix to generate an assembled asset data file of the media asset. The assembled asset data file can then be back-filled with selected ones of the cacheable segments that are replaced with a highest quality display format for on-demand presentation of the media asset when selected for viewing.

  • Delivering Cacheable Streaming Media Presentations

    Filed US 20100235528

    A smooth streaming system provides a stateless protocol between a client and server in which the server embeds incremental control information in media fragments. The server provides uniform media fragment responses to media fragment requests that are cacheable by existing Internet cache infrastructure. The smooth streaming system receives media data in fragments from one or more encoders, creates an index of each fragment, and stores the fragments. The server provides fragments to clients that…

    A smooth streaming system provides a stateless protocol between a client and server in which the server embeds incremental control information in media fragments. The server provides uniform media fragment responses to media fragment requests that are cacheable by existing Internet cache infrastructure. The smooth streaming system receives media data in fragments from one or more encoders, creates an index of each fragment, and stores the fragments. The server provides fragments to clients that contain metadata information describing the encodings available on the server and the encoding of the fragment. The server may also provide information within each fragment that allows the client to determine whether the client is requesting data too fast or too slow, so that the client can adapt its request rate to a cadence in tune with the rate at which the server is receiving encoder data.
