20090135918 | SYSTEM AND METHOD FOR PROVIDING A VARIABLE FRAME RATE AND ADAPTIVE FRAME SKIPPING ON A MOBILE DEVICE - A processor and method are provided for decoding a multimedia file having video and audio data streams that are configured to be played in synchronization. Frames of the video stream are decoded and played with the audio and, to compensate for saturation of the processor usage, two procedures are performed. The first procedure operates at a first periodic interval and slows down the frame rate to reduce processor usage if needed. The second procedure first attempts to speed up the video to catch up to the audio if they are out of sync and if this cannot be done in the next time interval, the decoding of a select number of frames is skipped such that the video and audio data streams are resynchronized. | 05-28-2009 |
20090138962 | Methods And Apparatus For Use In Establishing Communications For Virtual Private Networking - In one illustrative example, a mobile communication device includes a wireless transceiver, one or more processors coupled to the wireless transceiver, and memory for storing a communications application. The communications application may be a VoIP telephony application which involves communication in accordance with a session initiation protocol (SIP). The processor operates to establish the communications for the communications application by performing the following acts upon invocation of the communications application when the mobile communication device is connected in a communication network outside of a private network. Initially, the processor causes a request for a virtual private network (VPN) connection with the private network to be communicated, and awaits the establishment of the VPN connection. If the VPN connection is established within a predetermined period of time, the processor operates to receive a private IP address of the private network which is assigned to the mobile communication device and cause a request for registration using the private IP address to be communicated to a registration server for the private network. If the VPN connection is not established within the predetermined period of time, however, the processor cause a request for registration using a public IP address assigned to the mobile communication device to be communicated to a registration server for the communication network. After registration with the registration server, cause the communications to be established. | 05-28-2009 |
20110134898 | Secure Provisioning Methods And Apparatus For Mobile Communication Devices Operating In Wireless Local Area Networks (WLANS) - A wireless local area network (WLAN) includes a plurality of wireless access points (APs) which provide communications for a plurality of mobile communication devices.
