摘要： Publishing content using a peer-to-peer content distribution system is described. A publisher is required to request authorization to publish from an authorization body. Resources such as tracker and seed nodes are allocated in a peer-to-peer content distribution system and pre-processing of content to be published is carried out. For example, a content description is generated for each item of content as well as a set of checksums or other items for validating blocks of content. Publication can be terminated in a variety of different ways. For example, by using expiry methods, by active revocation of publishers, authorization bodies, or individual items of content.

摘要： Protecting elementary stream media content is described. In one aspect, data segments within elementary stream media content are identified. Each data segment includes a single video or audio frame. Encryption boundaries for protecting the payload packets are selected to correspond to data segment boundaries. The elementary stream media content is then protected using the selected encryption boundaries.

摘要： Systems and methods for midstream determination of varying available bandwidth for streaming content between two network entities are described. During content streaming, a client requests a server to surge the content transmission rate. One or more bandwidth measurements are taken during the surge to determine if the increased transmission rate can be adequately managed. If the increased transmission rate can be adequately managed, the client may request the server to transmit remaining content at a transmission rate that is not greater than the increased, or surged, transmission rate. In a multi-bitrate file scenario, the surge rate may be higher than the rate of the fastest useable stream. In such a case, the fastest useable stream is selected. If the increased transmission rate is not suitable for future transmission, then the rate may remain at the original transmission rate.

摘要： A system and process for performing an exponentially weighted moving average on streaming data to establish a moving average bit rate of data units is presented. In general, the system or process computes, on a unit-by-unit basis, the product of the moving average bit rate computed for a data unit immediately prior to a unit under consideration and a first fractional weighting factor, added to the product of the instantaneous bit rate of the data unit under consideration and a second fractional weighting factor, wherein at least one fractional weighting factor is not a constant but instead based on the time between data units.

摘要： An implementation, as described herein, facilitates fast start-up of a new media stream while mitigating and in some implementations, avoiding temporal interruption (i.e., “stutter”) of the presentation of that new media stream. At least one implementation, described herein, measures a rate at which a multimedia stream is received at a downstream component configured to present the multimedia to a user; and, ascertains a duration of time to buffer the received multimedia before presentation thereof, at least in part utilizing the measured rate.

摘要： Various functionality with respect to streaming media content is made available to users. Such functionality includes one or more of: streaming media content at a rate independent of the encoded bit rate of the content, allowing streaming of content to continue even when the user has selected various shuttle control options (e.g., pause, stop, fast forward, seek, rewind, etc.), allowing streaming content to be recorded for playback at a later time, and allowing streaming content to be time-shifted.

摘要： A method for employing a Hypertext Transfer Protocol (HTTP protocol) for transmitting streamed digital media data from a server. The server is configured for coupling to a client computer via a computer network. The method includes receiving at the server from the client an HTTP POST request. The POST request requests a first portion of the digital media data and includes a request header and a request entity-body. The request entity body includes a media command for causing the first portion of the digital media data to be sent from the server to the client. The method further includes sending an HTTP response to the client from the server. The HTTP response includes a response header and a response entity body. The response entity body includes at least a portion of the fast portion of the digital media data.
