Abstract: The positioning capabilities of a User Equipment (UE) are stored in a core network to reduce positioning latency when the UE indicates that its positioning capabilities are stable and/or are long term valid. The UE may provide its positioning capabilities to a location server during a location session along with an indication of whether the positioning capabilities are stable. The location server may enable storage of the positioning capabilities for the UE in the core network, e.g., in the location server or another entity in the core network such as Access and Mobility Management Function (AMF), if there is an indication that the positioning capabilities are stable. The AMF may include a UE identifier in location requests with which the location server may retrieve the UE positioning capabilities if stored at the location server or may include the UE positioning capabilities if stored at the AMF.

In one aspect, a computer-implemented method includes identifying and transmitting a sequence of frames in a digital video transmission, the sequence of frames comprising an initial frame and subsequent frames corresponding to the initial frame, the subsequent frames comprising data that incrementally updates the initial frame, and initiating a new transmission of the sequence of frames to a new device after sending one of the subsequent frames in the digital transmission, the initiating comprising generating information to cause the new device to inhibit presenting the new transmission until after frames between and including the initial frame and the one of the subsequent frames have been received by the new device, and transmitting, to the new device, the information and the frames between and including the initial frame and the one of the subsequent frames.

Abstract: A computer-implemented method performed by a server including obtaining a stream of live data comprising a plurality of segments; storing the plurality of segments to form a recorded stream; transmitting the plurality of segments as a near-live feed to one or more nodes in a network; transmitting the recorded stream to another node in the network; and transitioning from transmission to the another node of the recorded stream to the near-live feed, the transmission comprising: delaying transmission of the near-live feed to the another node until a new segment of the stream of live data is obtained.

Abstract: A method for printing a print ready file transmitted by a print client on an imaging device includes creating a print data file associated with the print ready file, where the print data file includes information pertaining to the print ready file and the imaging device. In the method, the print data file is encrypted and transmitted to the imaging device. In addition, the print data file is authenticated in the imaging device and printing of the print ready file is enabled if the print data file is determined to be authentic and the print ready file is invalidated if the print data file is determined to be inauthentic. Also disclosed is an imaging device configured to perform the aforementioned method.

Abstract: Systems, methods, and computer program products permit communication between servers in a server system utilizing a proxy stream communicating over a connection between the servers. A first request for content is received, at a server, and a connection is created with at least one upstream server. At the server a name associated with the content at the upstream server is identified. A second request for the content is transmitted to the at least one upstream server, where the second request identifies the name. The content is then received at the downstream server.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for fast switching of media streams, are described. The methods and systems described in this specification enable switching media streams as quickly as possible without playback interruption by not having to playback the content of the full buffer prior to the switch to the new stream. The fast switching disclosed in this specification is based on configuring a media player operated at a client computer to specify a switching time offset that corresponds to buffered content. In addition, the disclosed methods and systems enable a media streaming server computer, that is streaming a first media stream to the client computer, to select a key frame of a second media stream that is at or near a switching time offset specified by the client computer, and to immediately begin transmission of the second media stream.

Abstract: A system and method is disclosed for establishing an interactive multimedia application environment in which server-side streaming media may be controlled by a client using a programming model provided at both a communication server and an interactive multimedia runtime on the client. The application program interface (API) preferably provides methods for the client user to establish a stream of data from the client to the communication server in addition to allowing a stream from the communication server to the client. The API also preferably allows the user at a client to exert control over the broadcasting of the media streams. Streams may be built, edited, paused, stopped, augmented, and the like by the client user. Each function that the client user may operate on the broadcast media stream is preferably viewable by all of the other subscribing clients.

Abstract: Representative embodiments are disclosed of a system and method for linearly exposing client-server interaction comprising interpreting a function command representing a first group of sequential action requests to an integrated multimedia communication server (iMCS), sequentially transmitting the first group of sequential action requests from an interactive multimedia runtime (iMR) client to the iMCS, wherein a next sequential action request of the first group is transmitted to the iMCS prior to receiving a response message from the iMCS associated with a previous sequential action request of the first group, queuing response messages received from the iMCS, and handling the queued response messages.

Abstract: Methods, systems, and apparatus, including computer program products, for using data keyframes. In one aspect, a method includes storing a data keyframe transmitted as part of a live streaming broadcast; receiving a request from a client to join the live streaming broadcast in-progress; determining that the stored data keyframe was transmitted before the request from the client was received; transmitting the stored data keyframe to the client; and distributing streaming content associated with the live streaming broadcast to the client. Further, the data keyframe can be generated by a publisher of the live streaming broadcast. Distributing streaming content further can include storing a plurality of data keyframes transmitted as part of the live streaming broadcast and transmitting the plurality of stored data keyframes to the client before distributing streaming content associated with the live streaming broadcast to the client.
