A system for bit-rate stream playout at preset speeds including a regular playout speed and other than the regular playout speed includes multiple streams encoded at a same bit-rate (R) but at a plurality of playout speeds. A selection mechanism is responsive to requests for playout speeds. The selection mechanism selects from among the plurality of streams to service a request.

Bit-rate constrained trick play through stream switching and adaptive streaming

A system, method, and computer-readable medium that provides a streamed presentation to multiple clients over a network utilizing a presentation server that produces and streams audio, video, and uniquely identified auxiliary data objects (e.g., slides, 3D image models, sound bytes, web page, etc.) in separate sessions or channels over a network; a transmit queue associated with the presentation server to store uniquely identified repeatable auxiliary data objects; and a client that renders all data objects and stores the auxiliary data objects in a local memory cache so that they may be recalled according to their unique ID tags. The presentation server sends unique ID tags rather than the auxiliary data object content when repeated during the presentation. The client is responsive to unique ID tags to obtain an auxiliary data object from a local memory cache to render auxiliary content that is repeatedly presented during the presentation. A secondary network session may be made available to clients that join after the start of the presentation in order to obtain current auxiliary content.
