摘要： In embodiments of broadcast content to HTTP client conversion, a client converter receives video content as an input of broadcast content data streams from a content distribution system. The client converter can join a content data stream of the broadcast input, and convert the content data stream to unicast HTTP data, such as video content segments that are buffered for communication to a client device or to a media player of a client device. An HTTP server of the client converter can then communicate the unicast HTTP data to the client device or to the media player for playback of the video content.

摘要： An example method includes requesting a data stream using a buffer with an initial maximum window size for buffering received data associated with the requested data stream, receiving into the buffer one or more data segments associated with the data stream, removing from the buffer one or more data segments for use by a receiving device, and determining a current window size of the buffer, wherein the current window size is equal to the maximum window size less any data segments which have been received that have not been removed from the buffer. The method further includes comparing the current window size to a predetermined threshold, and in response to determining that the current window size is less than the predetermined threshold, increasing the maximum window size, and initiating a buffer size increase timer having a current timer value and a timer expiration value.

摘要翻译： 在广播内容到HTTP客户端转换的实施例中，客户端转换器从内容分发系统接收作为广播内容数据流的输入的视频内容。 客户端转换器可以加入广播输入的内容数据流，并且将内容数据流转换为单播HTTP数据，例如缓冲用于通信的视频内容片段到客户端设备或客户端设备的媒体播放器。 然后，客户端转换器的HTTP服务器可以将单播HTTP数据传送到客户端设备或媒体播放器，以播放视频内容。
