METHOD AND APPARATUS FOR PROVIDING A PLURALITY OF TRANSCODED CONTENT STREAMS

摘要

A method of providing a plurality of versions of a content stream with different bit-rates is suggested. According to the method each version has been transcoded from the same input content stream. The method comprises the following steps:
a) offering the transcoded versions of the content stream to a client;
b) preparing a manifest part;
c) submitting the manifest part to the client;
d) receiving a request from the client for one specific version of the content stream; and
e) dynamically selecting the bit-rate for transcoded versions to be offered to the client. The suggested method improves the adaptive transcoder 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.
