摘要: Techniques enable locating a position within a file that corresponds to a desired seek time without having access to an index specifying the desired seek time's position. An iterative process may be used to estimate the position that corresponds to the desired seek time. The process may iterate through multiple estimations until a difference between a time corresponding to an estimated position and the desired seek time is within an acceptable amount or until the process reaches an iteration threshold. The file may then be played beginning at or near the desired seek time. The techniques may therefore allow a user to seek within a file while the user progressively downloads or streams the file.

摘要: A computing system, which is in communication with a multimedia source and that includes at least one application for processing multimedia content from the multimedia source, includes an Application Programming Interface (API) for obtaining basic multimedia information that may be required by applications to process the multimedia content. By doing this, the invention enables multimedia application(s) to easily obtain the basic information from the API in a predetermined and standard manner, without having to obtain the information directly from the multimedia source, thereby reducing the functionality that has to be programmed directly into the application(s) for obtaining the basic information, and thereby reducing the cost, time, and resources that are required for creating the multimedia application(s).

摘要: The invention describes a control node for a content distribution network and a method of automatically verifying content distributed over a network at a node in the network. In the method, a content description is received which comprises a content identifier, a publisher identifier, publisher authorization information and content checking information. The integrity and validity of this information are checked and if both the checks are passed, the content description is stored.

摘要: Media processing methods, systems and application program interfaces (APIs) are described. In but one embodiment, a media engine component, also referred to as a media engine, provides a simple and unified way of rendering media from an origin to a destination of choice without requiring intimate knowledge about the underlying components, their connectivity and management. Clients of the media engine need not worry about how to render the particular media, but rather can simply focus on what media to render and where to render the media. In at least one embodiment, a media session is provided and is encapsulated by the media engine and provides a mechanism by which additional components are made transparent to the application and, in at least some embodiment, the media engine. In some embodiments, the media engine and media session provide a simple API for building, configuring, and manipulating a pipeline of components (e.g. media sources, transforms, and sinks) for media flow control between an origin and one or more destinations.

摘要: A method and computer-readable medium convert the text of a word and a user's pronunciation of the word into a phonetic description to be added to a speech recognition lexicon. Initially, two possible phonetic descriptions are generated. One phonetic description is formed from the text of the word. The other phonetic description is formed by decoding a speech signal representing the user's pronunciation of the word. Both phonetic descriptions are scored based on their correspondence to the user's pronunciation. The phonetic description with the highest score is then selected for entry in the speech recognition lexicon.
摘要翻译: 一种方法和计算机可读介质将单词的文本和用户的该单词的发音转换成要添加到语音识别词典的语音描述中。 最初,会生成两个可能的语音描述。 一个语音描述从单词的文字形成。 另一个语音描述是通过对表示用户对该单词的发音的语音信号进行解码形成的。 基于与用户发音的对应关系,语音描述都得分。 然后选择具有最高分数的语音描述,用于语音识别词典中的输入。
