TECHNIQUE FOR OPERATING CLIENT AND SERVER DEVICES IN A BROADCAST COMMUNICATION NETWORK

摘要

A technique for operating a client device (100) adapted to receive from a server device (200) via a broadcast communication network (102) a media stream comprising individual media segments is described. A method aspect of that technique comprises: determining first availability information, the first availability information indicating a predicted availability of one or more media segments (906) of a first media stream or a first part of the first media stream at the client device (100); determining, based on the first availability information and for at least one media segment of the first media stream or the first part of the first media stream received at the client device (100), a difference between the predicted availability and an actual availability at the client device (100); and transmitting difference information reflecting the determined difference for the at least one media segment to the server device (200).
