摘要： Methods and apparatuses provide real-time or near real-time streaming of content, specified in one or more playlists, using transfer protocols such as on HTTP compliant protocol. In one embodiment, a method can execute a user application on a client device to present media files and to control presentation of the media files. The method can further run a media serving process on the client device to retrieve a playlist specifying the media files and a media source at which the media files arc available, to retrieve the media files from the media source, and to decode the media files retrieved. While the media serving process is separate from the user application, they may share the same privileges with respect to memory control, memory space, memory allocation, file system control, and network control.

摘要： Methods, systems and machine readable storage medium for allowing playback of streaming media at playback rates of other than 1× are described. In one embodiment, a method can determine different sets of I-frames that are available before a display deadline, where each set can have a different cadence, and one of the sets can be selected for download and display to achieve playback at other than 1×. Byte range requests from a client device can be used to retrieve each of the I-frames. Other methods, system and media are also described.

摘要： Methods and apparatuses provide real-time or near real-time streaming of content, specified in one or more playlists, using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method can adaptively determine a minimum overlap for an overlap in time between two streams being received concurrently in order to determine when to switch between the two streams, and the minimum overlap can be determined based on connection speed. In another embodiment, a minimum playlist duration can be set as a multiple of a target duration which specifies a maximum duration of a media file specified in a playlist. In another embodiment, a method can enforce a start point for playback at a client device.

摘要： An initialization vector (IV) is employed to decrypt a block of a stream that has been encrypted with Cypher Block Chaining (CBC) encryption, without requiring decryption of previous blocks within the stream. For example, a listener who accesses a distribution point to retrieve encrypted content authenticates himself to an application server that regulates access to encrypted content on the distribution point, and responsively receives a key. The listener then requests access to a reference point within the encrypted content stream somewhere after its beginning (e.g., using preview clips). The distribution point relates the reference point to a corresponding block of the encrypted stream, and identifies an IV previously used for encryption of that block. The distribution point provides the associated encrypted block of content and the IV to the listener to enable mid-stream rendering of the encrypted content, without requiring the listener to decrypt previous blocks within the encrypted stream.
摘要翻译：使用初始化向量（IV）来解密已经使用Cypher块链接（CBC）加密加密的流的块，而不需要解析流内的先前块。例如，访问分发点以检索加密内容的监听者向调配对分发点上的加密内容的访问的应用服务器认证自身，并且响应地接收密钥。然后，收听者在其开始之后的某处（例如，使用预览剪辑）请求访问加密内容流中的参考点。分配点将参考点与加密流的相应块相关联，并且识别先前用于该块的加密的IV。分发点向收听者提供相关的加密内容块和IV，以允许加密内容的中间流呈现，而不需要收听者解密加密流中的先前块。

摘要： Methods and apparatuses provide real-time or near real-time streaming of content using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method includes providing multiple redundant locations that provide media content to client devices using alternative streams. To implement failover protection, a first server device or first content distribution service creates a stream, or multiple alternate bandwidth streams and generates playlist file(s). A second server device or second content distribution service creates a parallel stream, or set of streams. A client attempts to download the playlist file(s) from a first uniform resource locator (URL) using a first stream associated with the first server device or the first content distribution service. If a client is unable to download the playlist file(s) from the first URL, the client attempts to switch to an alternate stream associated with another URL.

摘要： Methods and apparatuses for real-time or near real-time streaming of content using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method includes dividing a stream of data, representing the contiguous time based content of a program (e.g. a live video broadcast), into a plurality of distinct media files, and generating a playlist file having a plurality of tags and Universal Resource Indicators (URIs) indicating an order of presentation of the plurality of distinct media files. The plurality of media files and the playlist file can be made available for transmission to a client device which can retrieve the media files using the playlist file.
