Abstract: A method for preparing media content for adaptive streaming, wherein the method comprises: determining a target quality for a media content that comprises a plurality of segments, detecting a plurality of content types that indicate a plurality of complexity for the segments, determining a plurality of bitrates for the content types using the target quality, and encoding the segments using the bitrates.

Abstract: Different representations are associated with an instance of media content, and a representation can include multiple portions of media content. A respective quality value and bitrate can be associated with each of the portions. Information about the instance of content, including bitrate and quality information, can be accessed by and/or sent to a client. The quality information indicates the availability of measures of quality (e.g., quality values) and where those quality values reside or how they can be retrieved. The client can use quality as well as bitrate to make more intelligent decisions while streaming the content. For example, while the content is being downloaded over a network, the client can adapt to changes in available network bandwidth by selecting one portion of the instance of media content over another based not just on its bitrate but also based on its quality value.

Abstract translation: 不同的表示与媒体内容的实例相关联，并且表示可以包括媒体内容的多个部分。 相应的质量值和比特率可以与每个部分相关联。 有关内容实例（包括比特率和质量信息）的信息可以由客户端访问和/或发送给客户端。 质量信息指示质量度量（例如，质量值）的可用性以及这些质量值在哪里或如何被检索的可用性。 客户端可以使用质量和比特率在流式传输内容时做出更明智的决策。 例如，当通过网络下载内容时，客户端可以通过不仅基于其比特率而且还基于其质量值，通过选择媒体内容的实例的一部分而不是基于其比特率来适应可用网络带宽的变化。
