Abstract
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.
