    摘要： A Method is described for synchronizing the output of terminals. The method according to the invention may be used in a system comprising a station, which transmits a packetized stream to at least a first and second terminal. Each terminal comprises a variable delay unit and each terminal is connected through a low-delay communication channel to at least one synchronization unit for calculating delay information. Further, each terminal is capable of determining media reference information of a received media unit from the stream. The method comprising the steps of providing one or more low delay communication channels between the terminals and a synchronization unit; the synchronization unit calculating delay information on the basis of synchronization information received from the terminals via the one or more low delay communication channels; and transmitting the delay information to at least one of the terminals allowing the at least one terminal to delay its output such that the output of the terminals are substantially synchronized.

    摘要： A method and controller are provided for performing a non-contiguous streaming of a media stream. Such non-contiguous streaming comprises transmitting a selected portion of the media stream to the receiver while omitting transmitting at least an immediately adjacent portion of the media stream so as to enable uninterrupted play-out of the selected portion by the receiver after a pre-determined play-out delay. Such non-contiguous streaming may be advantageously used when the content bitrate exceeds the available network bandwidth. Namely, instead of streaming all of the media stream, only one or more selected and non-adjacent portions thereof are streamed, while omitting transmitting one or more intermediate portions. Effectively, the available network bandwidth may be allocated for transmitting only selected portions of the media stream to enable said portions each to be played-out uninterruptedly by the receiver after a pre-determined play-out delay and at the original content bitrate. Buffer underruns at the receiver may thereby be prevented.
