    • Systems and methods may determine a visibility state of an application window associated with a media stream, and selectively decode a media stream based on a visibility state. One or more decode operations with respect to media content, such as video content, may be prevented if a visibility state indicates that at least a portion of an application window includes a blocked state. One or more decode operations with respect to media content, such as video content, may be permitted if a visibility state indicates that at least a portion of an application window includes a visible state. The systems and methods result in benefits to resource utilization, such as processor utilization, power consumption, and so on.
    • 系统和方法可以确定与媒体流相关联的应用窗口的可见性状态,并且基于可见性状态选择性地解码媒体流。 如果可视性状态指示应用程序窗口的至少一部分包括阻塞状态,则可以防止关于诸如视频内容的媒体内容的一个或多个解码操作。 如果可视性状态指示应用窗口的至少一部分包括可见状态,则可以允许关于诸如视频内容的媒体内容的一个或多个解码操作。 这些系统和方法可以为资源利用带来好处,如处理器利用率,功耗等。

    • Embodiments include systems and methods for allowing a host CPU to sleep while service presence packets and responses to search requests are sent by an alternate processor. While the CPU is in a low power state, the alternate processor monitors the network for incoming request packets. Also, while the CPU is asleep, the alternate processor periodically may transmit presence packets, announcing the presence of a service available from the host system of the CPU. In one embodiment, the alternate processor is a low power processor. If a search request is received when the CPU is in a low power state, the alternate processor responds to the search request according to whether the PC provides that service. If a service request is received, then the ME wakes the CPU of the PC to provide the requested service. In the wireless case, when the CPU is asleep, portions of the wireless upper MAC are implemented by the ME. When the CPU is awake the wireless upper MAC is implemented in the CPU. Thus, embodiments enable the PC to appear available to wireless devices when the CPU is asleep.
    • 实施例包括用于允许主机CPU睡眠的系统和方法,而服务存在分组和对搜索请求的响应由备用处理器发送。 当CPU处于低功耗状态时,备用处理器监视网络中的传入请求数据包。 此外,当CPU处于睡眠状态时,备用处理器周期性地可以传送存在分组,通知存在可从CPU的主机系统获得的服务。 在一个实施例中,替代处理器是低功率处理器。 如果在CPU处于低功率状态时接收到搜索请求,则备用处理器根据PC是否提供该服务来响应搜索请求。 如果接收到服务请求,则ME唤醒PC的CPU以提供所请求的服务。 在无线情况下,当CPU处于睡眠状态时,无线上MAC的部分由ME实现。 当CPU唤醒时,CPU中实现无线上MAC。 因此,当CPU处于睡眠状态时,实施例使PC能够显示对无线设备的可用性。

    • A computing device is equipped with file system services and media related services that automatically make visible to a user of the computing device, through an user interface of the file system, availability of media contents, on discovery of the availability of the media contents from one or more UPNP media servers. In various embodiments, the file system services and the media related services are further equipped to cause a selected one of the media contents to be rendered by an appropriate one of UPNP media renders, in response to a request to “render” the selected one of the media contents. In other embodiments, the file system services and the media related services may also facilitate removal of discovered media contents as well as addition of media contents to a media server.
