A method performed by a serving core network node in a communications network, for handling a service setup for a target User Equipment (UE) located in the communications network. The serving core network node receives a service setup request directed towards the target UE. The serving core network node sends a ping message to the target UE in response to the service setup request prior to a completion of a terminating service handling procedure of the serving network, wherein the terminating service handling procedure is completed when the service setup request is forwarded from a serving core network towards the target UE.

A method, computer system, and a computer program product for application sharing are provided. Setting information that includes a display preference of a receiver is received. Application content from a host computer is received. The application content includes at least one screen image. The at least one screen image is converted according to the setting information. The converted screen image is transmitted to a receiver computer for real-time screen sharing with the host computer. A host controller action signal is received. The host controller action signal represents a host controller action at the host computer. A content modification is transmitted to the receiver computer for the real-time screen sharing and for displaying with the converted at least one screen image. The content modification corresponds to the host controller action.

A casting control method and apparatus are provided. The casting control method and apparatus are applied to the field of video processing technologies. The method is applied to a first electronic device. The first electronic device includes a GPU and an HWC. When the first electronic device is in a casting state, the to-be-synthesized layer can be separately sent to the GPU and the HWC if the video security layer is not included. The first electronic device synthesizes the to-be-synthesized layer in parallel by using the GPU and the HWC.

Systems, methods, and computer-readable media for porting locally processed media data with low latency to a remote client device via various wireless links are provided. In one example embodiment, a transceiver module may include a local network interface and a controller that may receive a client control signal from a client device over a wireless local area network via the local network interface, transmit a media control signal based on the client control signal to a media device, receive media data based on the media control signal from the media device, and transmit to the client device over the wireless local area network via the local network interface client data based on the media data and a low-latency compression technique. The receipt of the media data and transmission of the client data may be accomplished with substantially no detectable latency. Additional embodiments are also provided.

In one implementation a method of transmitting a multimedia file over a data network is provided that involves receiving from a device in a data network a first message in a first protocol that request first data associated with the multimedia file, the first data being useable by the device to establish a streaming session that involves a transmission of the multimedia file. The first message includes identifying data of a referring site. The method also involves transmitting to the device the first data and optionally the identifying data of the referring site and then receiving from the device a second message in a second protocol for the purpose of creating a streaming session associated with the multimedia file. A streaming session is then created for transmitting the multimedia file to the device. In another implementation a method is provided that involves receiving in a computing device from a referring site an identifier of first data associated with a multimedia file and identifying data of the referring site, wherein the first data is useable for establishing a streaming session for downloading the multimedia file. The method further involves transmitting from the computing device a first message in a first protocol that requests the first data associated with the multimedia file and receiving in the computing device the first data. Upon receiving the first data the computing device transmits a second message in a second protocol for the purpose of creating the streaming session associated with the multimedia file, the second message including the first data and the identifying data of the referring site. The computing device then receives via the streaming session, all or a portion of the multimedia file. In some implementations, the first protocol and the second protocol are the same.
