摘要： A method of providing a plurality of versions of a content stream with different bit-rates is suggested. According to the method a set of versions of a content stream with different bit-rates is offered to a client. A manifest part describing the offered set of versions of the content stream is submitted to the client. The client requests one version of the content stream having a specific bit-rate. The bit-rate of the versions offered to the client is dynamically selected such that the difference between bit-rates of neighbouring versions is dynamically adapted. The suggested method improves adaptive transcoding so that it uses a small manifest part based on a small set of bit-rate values distributed around the currently delivered bit-rate. In addition to that a system is suggested for implementing the method.

摘要： A method of streaming an output content stream adaptively transcoded from a corresponding input content stream includes offering, to a client device, a number of alternative versions of the output content stream, for selection by the client device, and dividing the input content stream into two or more segments. Prior to the offering step at least a first segment of the input content stream is transcoded into at least one corresponding segment of an output content stream corresponding to at least one version from the number of alternative versions offered to the client device. Upon receiving a request from the client device for a selected version of the output content stream, streaming is begun with using a first one of the at least one corresponding segments of an output content stream corresponding to at least one version from the number of alternative versions offered to the client device that had been transcoded and stored prior to offering. Transcoding parameters are extracted from the request, for controlling the transcoding of a subsequent segment of the input content stream into the version selected by the client device, and the subsequent segment transcoded into the requested version is streamed to the client.
