Abstract: Systems and methods for video distribution synchronization are described herein. An example method to distribute a media stream over a distribution network to a number of devices may include determining, by one or more computer processors coupled to memory, a common master-client shared time reference Tref. Example methods may include determining a mean intermediate arrival time for first packets of a first type of the media stream, determining respective first playout times for the first packets based on the mean intermediate arrival time and the time reference Tref, associating the first packets with the respective first playout times, and distributing the media stream to the plurality of devices.

Abstract: There is provided a method for handling client device advertisement playlists, ad pods, and insertion of ad pods in a live or linear media content stream in a media distribution system (100) for distributing media content from a streaming source (50), e.g. a broadcast location (TV network, local TV studio, cable system, etc.) via a primary network to a streaming server (101) to client devices, when providing dynamic server-side advertisement insertion at an ad insertion server (130) which may be integrated in a streaming edge server (101) or free-standing, during live streaming of media content to a plurality of clients (151-153). The method comprises sending ad requests to an ad server (110) and pre-generating ad pods for each client in a speculative manner before an upcoming ad break is initiated. The media distribution system may typically be of IP type for live distribution of media content streams, e.g. video and/or audio, in view of which aspects of the inventive concept will be described.

Abstract: There is provided a method in a distribution network (200), comprising a central master node 101 for distributing a received media stream DO comprising packets of a first type over the distribution network to a multiple of client devices 151,152,153. The method comprising providing a common master-client shared time reference Tref, and determining a mean intermediate arrival time for received packets of the first type, which is utilized for providing playout time information for the packets together with the time reference Tref.

Abstract: There is provided a method and corresponding node and system for playout buffering and retransmission which can handle Over-The-Top (OTT) and Video-On-Demand (VOD) distribution to a large number of client devices, e.g. a server serving a number of client devices with e.g. the same TV-channel. The presented method comprises transmitting a data stream DS from a server 101 to at least two client devices 151-153, where a predetermined portion of client shared data of the data stream is buffered in a shared buffer. Upon receiving per client requests for retransmission of data from the client devices, requested data is retrieved from the shared buffer and retransmitted to the requesting client device. The method further comprises removing buffered data from said shared buffer based on if a time of interest for the buffered data has passed. The inventive concept is applicable in distribution of e.g. media data as in typical OTT and VOD, which is transported over unicast.
