Cross-Process Media Handling in a Voice-Over-Internet Protocol (VOIP) Application Platform

摘要

A computer-implemented system is provided that facilitates implementation of a voice-over-IP (VOIP) application. The system includes a host system and a user interface (UI) host process residing on the host system. The system also includes an agent host process residing on the host system which is being configured to process a VOIP call received by one or more VOIP applications executable on the host system. A moniker protocol is utilized for redirection of input and output between a media element which is utilized to render media on a display on the system. The redirection enables media processing to be allocated between the UI host process in the foreground and the agent host process in the background to thereby reduce latency perceived by a user during a VOIP experience.

主权项

1. A portable device, comprising:
one or more processors; a display; a wireless modem configured to enable the portable device to communicate over a network; one or more memory devices storing executable instructions which, when executed by the one or more processors, cause the portable device to implement a media element as a placeholder for rendered audio-video output associated with a voice-over-Internet protocol (VOIP) call carried on the network; utilize a dummy moniker configured to redirect input and output to and from the media element; receive notification of an incoming VOIP call on a push notification channel supported on the network; responsively to the notification, dispatch the incoming VOIP call to a background agent host process for processing; launch a foreground user interface (UI) host process to present a UI to a user on the display; inspect the dummy moniker to ascertain whether input to the media element is provided by the background agent host process; and responsively to the dummy moniker, accept input at the media element from the background agent host process, the background agent host process configured to write into a texture that is commonly accessible by the foreground UI host process and background agent host process using a shared handle.
