Media Device Presence Management
摘要:
A media player may be adapted to manage presence information distribution and access to facilitate media communication between compatible devices. Devices connecting in an ad-hoc or other network topology include a plurality of presence settings that determine how or if the device appears to be available for communication to other devices over the network. Additionally, the presence settings identify other, specific devices or groups of devices that may communicate with a device. By comparing the presence settings of a sending device with the settings of a receiving device, the receiving device may determine a presence state for all devices within communication range.
