Abstract: Systems and methods are provided for enhancing streaming performance through controlled and selectively-applied reductions in the color depth of streamed video content. In various embodiments, the method includes receiving, at a streaming media server, a request transmitted over a communications network to stream video content to a client media receiver. In response to this request, a streaming video session is initiated between the client media receiver and the streaming media server. During the streaming video session, the streaming media server obtains the video content as video input data having an original color depth; generates an encoded video stream from the video input data, while selectively reducing a color depth of the encoded video stream; and transmits the encoded video stream over the communications network to the client media receiver. The streaming media server repeats the steps of generating and transmitting until termination of the streaming video session.

Abstract: Optimizations are provided for reliably configuring an on-premise server using configuration data stored at a cloud-based service. An on-premise server polls the cloud-based service to determine whether any new configuration changes are available for the on-premise server to implement. In response to an indication that a new configuration change is available for the on-premise server, the on-premise server performs a validation to determine whether the new configuration change is committable by the on-premise server. Afterwards, the on-premise server receives the new configuration change and then attempts to commit to that new configuration change.

Abstract: The disclosure relates to technology for supporting context-aware content retrieval in a network. A router receives an interest message including a content name and a contextual requirement. Memory is accessed to determine whether the content name of the interest message matches a content name stored in the memory. In response to the content name matching the content name of the interest message, the router determines whether interfaces stored in the memory are associated with the content name. The contextual requirement in the interest message is matched with the contextual information associated with the interfaces stored in the memory, the interest message is forwarded to one of interfaces for which the contextual requirement in the interest message matches the contextual information of the interface(s) pertaining to the content. The router then aggregates the forwarded interest message including the contextual requirement with the pending interest message in the memory.

Abstract: An application based hardware identifier is generated for an application on a device. The application based hardware identifier is generated based on both information describing the application and information describing one or more hardware components of the device. The application based hardware identifier can also optionally be based on an identifier of a user of the device. The application based hardware identifier can be provided by the application to a service provider, allowing the service provider to associate the application based hardware identifier with a particular user or user account. However, as the application based hardware identifier is based on the application information, different applications on the same device will have different application based hardware identifiers. The application based hardware identifier thus helps maintain privacy by preventing tracking of the device across different applications.

The electronic communications method also receiving, by the electronic communications platform, the content, wherein the content includes a photo, a title, text, and a time limit for interacting with the electronic communications event.

Abstract: A messaging system enables client applications to send and receive messages. The messaging system includes independent component programs performing different functions of the messaging system. The component programs include persistent connection managers that maintain connections with the client applications, a dispatcher that establishes connections, and a message router that sends received messages to recipient applications through corresponding connections. The connection managers share a state memory containing a received message and a completion state associated with the received message. The messaging system retains the message until the completion state fulfills a completion condition. The messaging systems supports live deployment of updates the message router and dispatcher because the state of the messaging system is stored independently from memory allocated to these component programs, so they may be restarted without loss of messages, connections or other state information.
