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 server processers received real-time transport protocol packets from a first device to obtain sequentially ordered packets at a first buffer. The server decodes the sequentially ordered packets to obtain decoded packets at a decoder. The server encodes the decoded packets to obtain encoded packets at an encoder. The server transmits the encoded packets from the encoder to a storage unit. The server fetches the encoded packets from the storage unit at a first interval using a second buffer. The server transmits the encoded packets from the second buffer to a second device at a second interval.

Methods and systems are disclosed for supporting delay budget information in IMS systems. Requests for DBI are received by a first node, contained within a SIP message. This can be achieved by filling a feedback field within the signal with a delay budget indicator. The first node analyzes the received signal in order to determine whether DBI is being requested. Based on this analysis, a request signal is forwarded to a second node, which carries out resource reservation. The request signal can be based on a H.248:Add.req message. In this manner, DBI can be signaled and supported even without dedicated DBI messaging.

A user equipment, media control unit, media resource function, or another device or function capable of receiving, manipulating, and transmitting data may be configured to: receive an omnidirectional video; determine a viewport of a user equipment; determining a delivery mode; determine a region of the omnidirectional video based, at least partially, on the determined viewport and the determined delivery mode; encode the determined region; packetizing the encoded region; and transmit the packetized region to the user equipment based, at least partially, on the determined delivery mode.

A method is provided for performing zero-copy distribution of data samples between applications running on the same node in a system using an Object Management Group (OMG) Data Distribution Service (DDS) and/or a Real-Time Publish Subscribe (RTPS) protocol. Further provided is a method for selecting the network representation to communicate with a DataReader in a system using an Object Management Group (OMG) Real-Time Publish Subscribe (RTPS) protocol. Still further provided is the combination of these two methods to communicate transparently using zero-copy within the same node and not using zero-copy for different nodes. Embodiments of this invention lead to a relatively small communication latency that is constant and independent of the data size for applications running within a single node.

A computer implemented method allocates wireless network and adaptive video streaming resources in environments with high device density. The network has one or more access points and at least one user device. The stages of the method include obtaining the information from radio access network or video service telemetry; generating a resource allocation list between each user device and at least one channel with an associated representation index, distributing the resource allocation list, performing at least one handover and at least one video rate recommendation.

An information processing apparatus includes circuitry configured to receive a manifest file for a content stream, the manifest file including a manifest file update mechanism indicating one or more ways of receiving an update to the received manifest file. The circuitry is also configured to receive a manifest file update through the manifest file update mechanism indicated by the received manifest file. The manifest file update indicates that early termination of content during a period in the content stream is possible. The circuitry is also configured to send a request for the content associated with the period to a server based on the manifest file update, and receive the content from the server. The circuitry is also configured to output the content for display during the period and terminate the content early based on the manifest file update.
