Abstract: A system and methods for providing dynamic transcoder rate adaption for an adaptive bit streaming function is described. In a first embodiment, a client may select from all available bit rates during the encoding session, wherein the bit rates are provided to the client via a manifest file from a media gateway. In a second embodiment, a subset of the bit rates are provided to the client, from which a client chooses a selected bit rate. The encoding session continues until a request for a new bit rate is received from the client, at which time a new subset of bit rates are generated. This new subset of bit rates is presented to the client, and this loop continues until the termination of the encoding session.

Abstract translation: 描述了一种用于为自适应比特流功能提供动态代码转换器速率适配的系统和方法。 在第一实施例中，客户端可以在编码会话期间从所有可用比特率中进行选择，其中通过来自媒体网关的清单文件向客户端提供比特率。 在第二实施例中，将比特率的子集提供给客户机，客户端从该客户机中选择所选择的比特率。 编码会话继续，直到从客户端接收到对新比特率的请求，此时生成新的比特率子集。 将这种新的比特率子集提供给客户端，并且该循环将持续到编码会话的终止。
