Abstract: Described herein are various technologies pertaining to delivery of token-authenticated encrypted data. Content descriptor(s) (e.g., playlist(s)) can be modified to facilitate exchange of a token for a decryption key for browser(s) that do not provide logic to manage a flow of the token.

Abstract: A multispeed playback system is described herein that allows for playback of smooth streaming media presentations at speeds other than the normal speed or direction, while still using an underlying platform that does not natively support multispeed. The system provides frames to the underlying platform so that the platform is still playing 1× content while the system manipulates video and/or audio samples being fed to the platform to make rendered data look appropriately for a selected speed and direction. The system may feed the underlying platform frames at a faster rate or skip every other frame for faster playback, or may feed each frame to the underlying platform multiple times for slower playback. Thus, the multispeed playback system allows a client application developer to provide users with expected multispeed playback at the client without encoding multiple different streams at the server.

Abstract: A streaming composition system is described herein that provides easy workflow and playback capabilities for content producers to create composite media assets from existing and on-going media content and for streaming clients to seamlessly playback composite multimedia streams provided from different sources. These assets provide broadcasters an option to quickly turn around highlights for an on-going event. The streaming composition system allows a producer to identify clips within existing media assets and compose the clips into a new unified streaming presentation. For producers that already have smooth streaming media assets, the system leverages these assets to provide seamless playback across clip boundaries including advanced playback support for advertisement insertion, fast forward, rewind, and so on.

Abstract: A sparse streaming system provides a first-class means for sparse metadata to be added to streaming media presentations and to be delivered using an integrated data channel that is cacheable using readily available HTTP-based Internet caching infrastructure for increased scalability. The sparse streaming system stores a reference to a sparse track within a continuous track. If a continuous fragment arrives at the client that refers to a sparse fragment that the client has not yet retrieved, then the client requests the sparse fragment. In addition, each sparse fragment may include a backwards reference to the sparse fragment created immediately prior. The references in the continuous fragments make the client aware of new sparse track fragments, and the backwards references in the sparse track fragments ensure that the client has not missed any intervening sparse track fragments.

Abstract: A coordinated adaptive streaming system provides a level of intelligence between adaptive streaming heuristics applied to multiple multi-bitrate streams playing on a client computer at the same time. The system receives a media event that includes multiple multi-bitrate streams and plays two or more of the streams. Each stream registers with the coordinated adaptive streaming system so that the system is aware of each of the streams. The system receives a priority indication from each stream that indicates the priority of the stream relative to other streams associated with the media event. The system uses the received priority indications to make adaptive streaming decisions. Thus, the coordinated adaptive streaming system provides playback that more closely aligns with a user's priorities and provides a higher quality experience to a user viewing multiple concurrent media streams.

Abstract: A computer-implemented method for seamlessly playing a composite media presentation, includes receiving, by a sequencer, a sequential playlist provided by a scheduler. The sequential playlist refers to a sequence of one or more streaming media content items. The sequencer receives calls from a native player application at regular intervals, and sends playback segments and seekbar update information to the native player application based on the sequential playlist in response to the calls. The native player application is configured to play the composite media presentation using at least one core player and generate a corresponding seekbar for the presentation based on the playback segments and the seekbar update information sent by the sequencer.

Abstract: Embodiments are directed to pacing on-demand linear advertisement entries to appear as being live entries, to generating a sequential segment map from a parallel playlist and to consolidating linear ad and main content portions into a single linear chunklist. In one embodiment, a computer system receives video content updates for a portion of live video programming, and generates a parallel playlist with parallel playlist entries that identify a presentation that is to be played. The computer system then generates a sequential segment map from the parallel playlist that identifies which parallel playlist entry is to be played, monitors a live position for new media, determines that an on-demand linear advertisement is to be played at the live position, and appends on-demand linear advertisement chunks to a chunklist to replace the main content chunks and play the on-demand linear advertisement entries in a pseudo-live format as if they were live.

Abstract: In client-server architectures, systems and methods for implementing an extensible resource management platform at a server are described. The extensible resource management platform is developed based on a plug-in based architecture which includes one or more subsystems for performing functions associated with resource management. Different implementations can be provided by new or different components or plug-ins. The resource management platform is thus a platform over which one or more functionalities can be further added to supplement existing and varying functions.

Abstract: Media fragmentation may be provided. First, a request for a manifest may be received from a client. Then, in response to the received request for the manifest, the manifest may be sent to the client. Next, a request may be received from the client for a file fragment. The request may indicate a start time and an end time corresponding to the file fragment. The request may be in a format defined by the manifest. Then a lookup table may be queried for a first byte location in a media file corresponding to the start time and a second byte location in the media file corresponding to the end time. Next, a portion of the media file between the first byte location and the second byte location may be extracted from the media file. The portion may comprise the file fragment. The file fragment may be sent to the client.

Abstract: A flexible logging system is described herein that operates with a web server to provide activity logging in a way that is customizable to include a variety of data fields, can capture both client and server log information to a single location, and can provide data to an analysis engine directly to provide near real-time reporting. The system captures events within the web server as they occur and can provide reporting before the final response occurs. During request processing in the web server, server extension modules raise log events whenever an event occurs. The system matches the received data to a log definition and writes the data to any log that matches. Thus, the flexible logging system provides a rich, flexible, and fast platform for content providers and administrators to get a real-time view of the state of requests to their web servers.

Abstract: 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.

Abstract: A computer-implemented method for archiving a live media presentation includes archiving the live media presentation as it is being streamed from a live server, wherein the archiving includes recording the live media presentation in fixed-length segments. A segment name is associated with each of the segments, wherein each of the segment names includes a time stamp. The fixed-length segments are stored on a video on-demand (VOD) server. A manifest is generated that describes at least a portion of the live media presentation and identifies a uniform resource locator (URL) to be used by a client device to access a first one of the segments, wherein the URL includes the segment name of the first segment.

Abstract: A method in a portable electronic device (100) of authenticating enhanced wide area network data usage capabilities is provided. Data communication between the portable electronic device and a wide area network (104) is detected, along with commencement a dual-operating system hybrid environment (111). The dual-operating system hybrid environment can include a first operating system environment (114) operable to communicate with the wide area network at a restricted data rate and a second operating system environment (116) operable to communicate with the wide area network at either the restricted data rate or an enhanced data rate. A verification whether the portable electronic device is authorized to communicate with the wide area network at the enhanced data rate is then performed. Where true, the second operating system environment can be configured to communicate with the wide area network at the enhanced data rate.
