Techniques for client controlled pacing of media streams

In various embodiments, a media delivery application transmits an encoded block of a media title to a playback application. In operation, a media delivery application receives, via a media channel, a coded block request that has been transmitted over a TCP connection. The media delivery application also receives, via the side channel, a step specification associated with the encoded block request and having been transmitted over the TCP connection. In accordance with the encoded block request, the media delivery application retrieves encoded block content. Based on the step specification, the media delivery application sets a parameter associated with the TCP connection to be equal to the parameter value. The media delivery application then causes a TCP segment corresponding to the encoded block content to be transmitted over the TCP connection via the media channel according to the first parameter value. 在各种实施例中，媒体递送应用向回放应用传输媒体标题的编码块。在操作中，媒体递送应用经由媒体信道接收已经通过TCP连接传输的编码块请求。媒体递送应用还经由侧信道接收与编码的块请求相关联并且已经通过TCP连接传输的
