摘要： Systems and methods are described for minimizing power consumption of a mobile user device that transfers content from an internal or external memory module to a wireless display. The content may be encrypted to secure against unauthorized access and encoded to compress the memory size of the content for transmission to other devices. In certain instances, the mobile user device may not be the ideal display device for the content. For example, a user may want a movie to be played on a bigger screen. In this case, the mobile user device may provide the encrypted and encoded content to a wireless display for decryption and decoding. In this way, the mobile user device may not decrypt or decode the content prior to transmitting the content to the mobile user device. Thereby, the mobile user device saves power by foregoing the aforementioned processing.
摘要翻译：描述了将内容从外部存储器模块传送到无线显示器的移动用户设备的功率消耗最小化的系统和方法。内容可以被加密以防止未经授权的访问并被编码以压缩内容的存储器大小以传输到其他设备。在某些情况下，移动用户设备可能不是内容的理想显示设备。例如，用户可能希望在更大的屏幕上播放电影。在这种情况下，移动用户设备可以将加密和编码的内容提供给无线显示器用于解密和解码。以这种方式，移动用户设备可以在将内容发送到移动用户设备之前不会对内容进行解密或解码。因此，移动用户装置通过前述的处理来节省功率。

摘要： Various embodiments are generally directed to techniques for incorporating full-resolution frames in a coding order and corresponding thumbnail images of a motion video into compressed video data. A device to compress video frames includes a processor component; and a compression component for execution by the processor component to intersperse at least one compressed thumbnail frame (T-frame) among multiple compressed full-resolution frames of a motion video arranged in a coding order in a compressed video data, the T-frame comprising multiple thumbnail images of the motion video in compressed form. Other embodiments are described and claimed.

摘要： Methods, apparatuses and storage medium associated with securely provisioning a digital content protection scheme are disclosed. In various embodiments, a method may include forming a trust relationship between a media application within an application execution environment of a device and a security controller of the device. The application execution environment may include an operating system, and the operating system may control resources within the application execution environment. Additionally, the security controller may be outside the application execution environment, enabling components of the security controller to be secured from components of the operating system. Further, the method may include the security controller in enabling a digital content protection scheme for the media application to provide digital content to a digital content protection enabled transmitter within the application execution environment for provision to a digital content protection enabled receiver. Other embodiments may be disclosed or claimed.
