摘要： A decoder receives a set of N compressed segments of a first picture, and a set of M compressed segments for a second picture that follows the first picture in a decoding order. Based on the set of N compressed segments, the decoder constructs a decodable picture for the first picture and decodes the decodable picture. Based on the set of M compressed segments, the decoder constructs a decodable second picture in the compressed domain, in which each of the segments of the first picture are placed at the same spatial position as that of a corresponding segment in the second picture and decodes the decodable second picture. Additionally, at least one Intra coded segment is placed at one of the M spatial positions in the compressed domain in which there is no segment of the N segments.

摘要： Systems and methods that are particularly well-suited for service-based core network endpoint authentication are disclosed. In some embodiments, a method of operation of a network node implementing a second network function in a core network of a cellular communications system comprises receiving, at a main service of the second network function, a request from a first network function for a desired service via Hypertext Transfer Protocol/Representational State Transfer (HTTP/REST) signaling. The request comprises information that identifies one or more delegate endpoints of the first network function that expose one or more delegate services, respectively, of the first network function for providing the desired service using one or more different communication styles. The method further comprises initiating the desired service using a selected delegate endpoint from the one or more delegate endpoints identified by the information comprised in the request.

摘要： The present invention relates to a method and a transmitting apparatus for encoding a bitstream representing a sequence of pictures of a video stream comprising a processor and memory, said memory containing instructions executable by said processor whereby said transmitting apparatus is operative to: send a syntax element, wherein a value of the syntax element is indicative of restrictions that are enforced on the bitstream in a way that guarantees a certain level of parallelism for decoding the bitstream.

摘要： An apparatus in a mobile communication network combines information from monitoring IP flows carrying latency sensitive content passing the apparatus and information about the application behavior and target Quality of Experience (QoE) or target connectivity characteristics such as Quality of Service (QoS) from the application to provide ongoing predictions of QoE/QoS. In some cases, the apparatus exploits a probe on a device to generate traffic for learning flow characteristics not obtained from monitoring application IP flows in the network. Embodiments disclosed herein can be used to predict quality metrics for many applications where jitter/latency is a factor affecting perceived quality, such as QoE for a human consumer or QoS for machine type communications. The embodiments are applicable to the analysis of traffic carrying conversational speech.

摘要： A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.

摘要： A decoder (100) receives (30) a set of N compressed segments of a first picture, and a set of M compressed segments for a second picture that follows the first picture in a decoding order. Based on the set of N compressed segments, the decoder constructs a decodable picture for the first picture and decodes (32) the decodable picture. Based on the set of M compressed segments, the decoder constructs a decodable second picture in the compressed domain, in which each of the segments of the first picture are placed at the same spatial position as that of a corresponding segment in the second picture, and decodes (52) the decodable second picture. Additionally, at least one Intra coded segment is placed at one of the M spatial positions in the compressed domain in which there is no segment of the N segments.

摘要： A network information system for determining transport conditions in a communications network. Monitoring data is acquired from a plurality of data transport nodes in a communications network. Transport conditions are determined from network information related to transport flows for network transmission of real time media flows. The network information is determined from a subset of the acquired monitoring data. The determined transport conditions are provided to at least one of a network connected device running an application involving the network transmission of real time media flows and a data transport node involved in the network transmission of real time media flows.

摘要： A method at a first node for encoding a message for secure transmission to a second node comprising. The method includes receiving the message for transmission to the second node and fragmenting the message into a plurality of fragments, wherein each fragment is of a selected size. The method further includes encoding separately each fragment of the plurality of fragments using Datagram Transport Layer Security (DTLS), combining DTLS encoded fragments into a Stream Control Transmission Protocol (SCTP) message, and transmitting the message as a plurality of DTLS encoded fragments in the SCTP message to the second node.
