摘要： 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.

摘要： Systems and methodologies are described that facilitated generating a broadcast schedule of content based on user feedback. Users can provide feedback such as ratings, interest (e.g., like or dislike), comments, reviews, critiques and so on regarding content available on a media distribution system. The feedback can be utilized to determine a schedule or order of content that is delivered via a broadcast mechanism. In addition, users can supply contemporaneous feedback during broadcast. Contemporaneous feedback can be employed to enable dynamic adjustment and/or reconfigurations of the broadcast schedule.

摘要： Methods, apparatus, systems and computer program products are defined for enhancing the delivery of overhead notifications in a broadcast network, in particular a broadcast network suitable for wireless device implementation. The broadcast-receiving devices only receive new notification messages, as opposed to receiving all of the currently active notification messages. This is achieved by broadcasting a listing of the currently active notifications versions and having the devices compare the currently active notification versions to the locally stored version(s) to determine which version or versions require capturing. In those aspects in which the broadcast-receiving device is a battery powered wireless device, battery power consumption is minimized because the device only captures active notification messages not currently in device memory, as opposed to all of the currently active notifications.
摘要翻译：定义了方法，装置，系统和计算机程序产品，用于增强广播网络中的开销通知的传送，特别是适用于无线设备实现的广播网络。广播接收设备仅接收新的通知消息，而不是接收所有当前活动的通知消息。这通过广播当前活动的通知版本的列表并且使得设备将当前活动的通知版本与本地存储的版本进行比较来确定哪些版本或版本需要捕获来实现。在广播接收设备是电池供电的无线设备的那些方面，与所有当前活动的通知相反，因为设备仅捕获当前不在设备存储器中的活动通知消息，所以电池电力消耗被最小化。
