摘要： A computer system receives a request from a client computer system for data that is to be presented to a user, accesses a portion of the requested data and determines the encoded bit rate from the accessed portion of requested data. Based on the encoded bit rate for the requested data, the computer system determines an initial amount of data that is to be transferred to the client computer system to enable prompt access to that portion of data and determines the transfer rate for transferring the remaining data to the client computer system. The transfer rate for the remaining data is lower than the transfer rate for the initial amount. The computer system transfers the initial amount of data to the client computer system and transfers the remainder of the requested data to the client computer system at the determined lower transfer rate, subsequent to transferring the initial amount.

摘要： The dynamic management of download rates when downloading digital resources to clients. A server concurrently maintains download sessions with any number of clients, each download session for downloading a corresponding digital resource to a corresponding client. The download rates for the various download sessions are adjusted as download sessions are completed, and as new download sessions are added. As new download sessions are initiated, a minimum and target download rate may be calculated. The target download rate is the rate at which the server will attempt to download the requested digital resource to the client, and will depend on the total available bandwidth for use to download the digital resources.
摘要翻译：在向客户端下载数字资源时，下载速率的动态管理。服务器同时维护具有任何数量的客户端的下载会话，每个下载会话用于将相应的数字资源下载到相应的客户端。随着下载会话的完成，随着新的下载会话的添加，各种下载会话的下载速度也被调整。随着新的下载会话启动，可以计算最低和目标下载速率。目标下载速率是服务器尝试将请求的数字资源下载到客户端的速率，并且将取决于用于下载数字资源的总可用带宽。

摘要： Described is a technology in which media content is sent to clients in partial pieces, so that a server may control how clients view (and/or hear) the media content. A client requests partial content, and the server allows or disallows the request based upon one or more various conditions, as evaluated against a playlist provided (e.g., by a playlist provider) for that client. For example, the playlist may specify that the client cannot skip content, whereby the server disallows a request for a piece of content that skips over other content. Session related data may be kept to track the content sent to the client. Media content may be sent based on a dynamic condition, and/or the playlist may be dynamically adapted. A piece of media content may comprise an advertisement, which may be custom-selected for that client, such as based upon user profile data and/or client location information.

摘要： 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.

摘要： Dynamic transcoding of media content based on transcoding parameters. Upon receiving a request for media content to be delivered to a client, various parameters for transcoding the media content are identified. Such transcoding parameters might be tailored to the particular capabilities of the client presentation system. It not already done, the requested media content may then be transcoded in accordance with the identified parameters. The resulting media stream may then be provided to the client presentation device. In one example, if another request for that same media content is made and the transcoding parameters are identified to be the same, a second media stream may be provided to the second client presentation system.
摘要翻译：基于转码参数的媒体内容动态转码。在接收到要传送给客户端的媒体内容的请求时，识别用于代码转换媒体内容的各种参数。这样的代码转换参数可以针对客户端呈现系统的特定功能而定制。尚未完成，然后可以根据所识别的参数对所请求的媒体内容进行转码。然后可以将所得到的媒体流提供给客户端呈现设备。在一个示例中，如果对该相同媒体内容的另一请求被做出并且代码转换参数被识别为相同，则可以向第二客户端呈现系统提供第二媒体流。

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.
