    • Aspects of a method and apparatus for a secure system-on-a-chip (SOC) architecture for multimedia data processing are provided. A processor may configure at least one subsystem within the SOC via at least one unsecured bus while a security processor enables secure functionalities in configured subsystems via at least one secure bus. The unsecure buses may comprise a data bus and/or a control bus, for example. The secure buses may comprise a secure control bus and/or a secure key bus, for example. The configurable subsystems may be multimedia processing units, input and output modules, and/or memory controllers. The security processor may program bits in security registers within the subsystems to enable secure functionalities, such as data routing paths and/or key loading paths, for example. Moreover, the security processor may validate code to be executed by a processor for configuring the SOC subsystems.
    • 提供了用于多媒体数据处理的用于安全的片上系统(SOC)架构的方法和装置的方面。 处理器可以经由至少一个不安全总线在SOC内配置至少一个子系统,而安全处理器通过至少一个安全总线实现配置子系统中的安全功能。 例如,不安全的总线可以包括数据总线和/或控制总线。 例如,安全总线可以包括安全控制总线和/或安全密钥总线。 可配置子系统可以是多媒体处理单元,输入和输出模块,和/或存储器控制器。 安全处理器可以对子系统内的安全寄存器中的位进行编程,以实现例如数据路由路径和/或密钥加载路径等安全功能。 此外,安全处理器可以验证由处理器执行的用于配置SOC子系统的代码。

    • A monoscopic video camera may capture, via at least one image sensor, two-dimensional video, and may capture, via at least one depth sensor, corresponding depth information for the captured two-dimensional video. The monoscopic video camera may then adaptively configure scaling operations applicable to the captured two-dimensional video based on the depth information, which may comprise variably scaling different portions of the two-dimensional video. In this regard, the monoscopic video camera may determine, based on the depth information, a plurality of depth planes. The different portions of the two-dimensional video that are subjected to variable scaling may be determined based on the plurality of depth planes. Configuration of scaling operations may be performed in response to user input, which may comprise a zoom command. In this regard, scaling operations may be configured to focus on one or more of the different portions of the two-dimensional video based on zoom commands.
    • 单视摄像机可以经由至少一个图像传感器捕获二维视频,并且可以经由至少一个深度传感器捕获用于所捕获的二维视频的对应深度信息。 然后,单视视频摄像机可以基于深度信息自适应地配置适用于所捕获的二维视频的缩放操作,深度信息可以包括可变地缩放二维视频的不同部分。 在这方面,单视摄像机可以基于深度信息确定多个深度平面。 可以基于多个深度平面来确定经受可变缩放的二维视频的不同部分。 可以响应于可以包括缩放命令的用户输入来执行缩放操作的配置。 在这方面,缩放操作可以被配置为基于缩放命令来关注二维视频的一个或多个不同部分。
