Abstract: Techniques for video encoding and decoding channel switch frames (CSF) to enable acquisition and re/synchronization of the video stream while preserving compression efficiency is provided. Systems and methods to process multimedia data enabling channel switching are presented. The systems generate a CSF with one or more network adaptation layer (NAL) units as a random access point (RAP) frame. Back-to-back frames are transmitted which include the CSF and a non-RAP frame, each having the same frame ID number.

Abstract: A method and apparatus for negotiating capability information for a broadcast service in a communication system. In one embodiment, the generic capabilities are pre-configured in BSC, which provides the generic capability information to MS and to PDSN based on a listing of available BC services and the corresponding capabilities. Another embodiment pre-configures PDSN with the generic capability information. According to still another embodiment, PDSN is pre-configured with the generic capability information, wherein the MS queries the PDSN directly for generic capability information via a PPP connection. In yet another embodiment, the MS queries the PCF, which in turn queries all of the PDSN in the system. The PDSN responsible for the BC responds to the query. Where multiple PDSNs may support the BC, the first to respond using multicast addressing obviates the need for the others to respond.

Abstract: A method of providing content notifications to devices in a wireless communication system includes obtaining notification information regarding content available to a first group of mobile devices in a wireless network, generating a notification message comprising the notification information and an identifier associated with a second group of mobile devices that is a subset of the first group, and broadcasting the notification message over the network to cause mobile devices of the second group to retrieve the content over the network. The method also includes receiving content notifications in a wireless communication system, including receiving a notification message comprising notification information regarding content available to a first group of mobile devices and an identifier associated with a second group of devices, where the second group is a subset of the first group, and retrieving content from a network in response to being one of the second group of devices.

Abstract: Systems and methodologies are described that facilitate providing software upgrade notifications to user devices that utilize unicast and multicast communication techniques in a wireless communication environment. Bandwidth and power consumption is minimized by permitting determination to be made regarding whether a given software update is relevant to the user device prior to attempting a download or receiving a notification thereof. Additionally, evaluation of version number and software identity facilitates determining whether to employ a unicast software check-up protocol or a multicast software check-up protocol. Software upgrade information may also be transmitted over a multicast channel for a predetermined time period, after which a user device may initiate a unicast check-up protocol to receive software upgrade information.

Abstract: The disclosure is directed to a mobile communication device that may receive wireless broadcast signals from a number of different base stations or transmitters. The device alternates its operation between a low-power mode and a higher-power mode to conserve battery power. The length of time the device remains in the sleep mode is its sleep interval. The sleep interval is a function of two components. One component is set by the wireless broadcast network and the other component is set by the carrier that provisions the mobile communications device. When the device awakens from the sleep mode, it can check the status of any notification messages. If there are any updates, then it will process them. If there are no updates, then it will return to the low-power mode.
