  • Handling Of Content Delivery In A Client Node
    Publication number: 20180332089
    Abstract: There is provided mechanisms for handling content delivery in a client node. A method being performed by the client node. The method comprises registering, by an application entity of the client node and with an MBMS entity of the client node, for enabling the client node to receive content delivered by encrypted unicast transmission and to receive the content delivered by broadcast transmission. The method comprises selectively controlling, by a trusted entity of the client node, reception of the content in a media player of the client node between reception of the encrypted unicast transmission and broadcast transmission depending on whether the content is available or not for reception on the broadcast transmission.

  • ADAPTIVE PRECISION FOR REPORTING CONSUMPTION OF STREAMED CONTENT
    Publication number: 20180310056
    Abstract: A node (200) of a communication network determines a precision to be applied for reporting of consumption of streamed content. The node (200) sends configuration information (304) indicating the precision towards a plurality of client devices (10). After receiving reports of consumption (308) of the streamed content from at least some of the client devices (10), the node (200) adapts the precision to be applied for said reporting of consumption of the streamed content and sends further configuration information indicating the adapted precision towards the client devices (10).

  • Method and Arrangement for Supporting Playout of Content
    Publication number: 20180262712
    Abstract: Methods and arrangements in a client node and a server node support a decision on decoding and playout of a certain content in the client node. The methods and arrangements relate to the determining, conveying and obtaining of information related to the characteristics (level) required for decoding and playing out the certain media content at a non-regular playout rate. The method and arrangement in the client node further relate to determining, based on the obtained information, which playout rate(s) is/are supported by the client node in regard of level. The methods and arrangements enable the client node to refrain from attempting to decode and play out of the content at a non-regular rate requiring a level which is not supported by the client node.

  • Throttling a media stream for transmission via a radio access network
    Patent number: 9967303
    Abstract: A method of throttling a media stream, comprising a sequence of media segments, for transmission to a client via a radio access network is provided. The method comprises acquiring a media segment, determining a duration of the media segment, transmitting a first part (501?-504?) of the media segment to the client, and transmitting a remaining part (501?-504?) of the media segment to the client. At least one of the parts (501?-504?, 501?-504?) is transmitted during a time interval (?t1, ?t2) which is shorter than a corresponding duration of that part, and transmitting the remaining part is delayed (?t0), such that a time interval (?ttx) between starting transmitting the first part and transmission of the remaining part being completed is shorter than the duration (?tp) of the media segment. Further, a corresponding network node for throttling a media stream is provided.

  • Streaming with Optional Broadcast Delivery of Data Segments
    Publication number: 20180070149
    Abstract: For streaming data in a mobile communication network, a descriptive file of a stream is provided. The descriptive file comprises a list of delivery source identifiers, e.g. URIs, for unicast delivery of data segments of the stream.

  • Technique for reliable bulk data delivery
    Patent number: 9787802
    Abstract: Presented is a technique for broadcasting content data from a broadcaster (including a multicaster) to a plurality of clients. After a client receives content data from the broadcaster, a plurality of available proxy servers may be contacted, within a specified time interval, for post-processing after the content data broadcast is determined. The client subsequently randomly selects one of the available proxy servers to contact for post-processing after the content data broadcast. The client then randomly selects a delay time within the contact interval for the selected proxy server, at which time the client contacts the selected proxy server at the delay time to initiate post-processing.

  • PROCESSING OF MULTIMEDIA DATA
    Publication number: 20170257412
    Abstract: Techniques for providing media content in a broadcast scenario to a streaming player. In order to compensate a problem of variable segment sizes, which leads to the variation in the reception intervals of the media segments, it is proposed to estimate the segment availability time for requesting subsequent media segments. The estimation considers a correction value compensating the variation in a reception intervals of media segments so that the streaming player receives the media segments at a constant time interval, namely at the segment duration. In one embodiment it is proposed to use the value of the minBufferTime from the MPD file, The minBufferTime is namely an indication of the varying segment size of the media content. The minBufferTime indicates the time needed for buffering a media content before starting playing out said media content. The estimation may be done on the client or on the server device side.

  • Processing of multimedia data
    Patent number: 9712585
    Abstract: The invention relates to techniques for providing media content in a broadcast scenario to a streaming player, like a DASH player. In order to compensate a problem of variable segment sizes, which leads to the variation in the reception intervals of the media segments, it is proposed to estimate the segment availability time for requesting sub-sequent media segments. The estimation considers a correction value compensating the variation in a reception intervals of media segments so that the streaming player receives the media segments at a constant time interval, namely at the segment duration. In one embodiment it is proposed to use the value of the minBufferTime from the MPDfile, The min BufferTime is namely an indication of the varying segment size of the media content. The minBufferTime indicates the time needed for buffering a media content before starting playing out said media content. The estimation may be done on the client, user equipment UEor on the server device side.

  • Controlling streaming of data from a streaming server to a user equipment via a radio access network
    Patent number: 9641581
    Abstract: A method of controlling streaming of data, such as video, from a streaming server to a User Equipment (UE) via a Radio Access Network (RAN) is provided. The method includes receiving streaming data from the streaming server, re-shaping the received streaming data into bursts, and transmitting the bursts to the UE. The bursts are transmitted at a higher bitrate than the bitrate of the received streaming data. By re-shaping the streaming data into bursts, streaming can be effected in a more radio-friendly way, since the UE may switch to a less resource consuming radio state in-between reception of data bursts delivered at high bitrates. Further, a corresponding computer program and computer program product, and a proxy unit for controlling streaming of data from a streaming server to a UE via a RAN, are provided.
