    • The present disclosure relates to parsing encrypted content and sending the encrypted content to appropriate stacks of components. Encrypted video content is sent to a video stack and encrypted audio content is sent to an audio stack. Components in either stack may or may not be able to decrypt the encrypted content. A common interface is provided to the components to pass encrypted content and encryption content with one another. Components not able to perform decryption pass on the encrypted content to succeeding components in the stack until a component capable of decrypting the encrypted content receives the encrypted content. Control from a hardware lawyer in a stack may be sent back through the stack using a secure link established by the common interfaces used by the components.
    • 本公开涉及解析加密内容并将加密的内容发送到适当的组件堆栈。 加密的视频内容被发送到视频堆栈,加密的音频内容被发送到音频栈。 任一堆栈中的组件可能会或可能无法解密加密的内容。 向组件提供通用接口以将加密的内容和加密内容彼此传递。 不能执行解密的组件将加密内容传递给堆叠中的后续组件,直到能够解密加密内容的组件接收加密内容。 可以使用由组件使用的公共接口建立的安全链路,通过堆栈来从堆栈中的硬件律师进行控制。

    • Methods, microphones, and processors are provided for processing ambient sound waves. Ultrasound waves are combined with the sound waves to create heterodyned sound waves. The heterodyned sound waves are detected and, in response, a sound detection signal containing information relating to the heterodyned sound waves is generated. A heterodyned audio signal representing the heterodyned sound waves is generated at least partially based on the sound detection signal, and then an ambient sound signal representing the ambient sounds is derived from the heterodyned audio signal. Methods, microphones, and systems are provided for processing sound waves. The sound waves are detected with a portable device (such as a microphone) and an audio signal representing the sound waves is generated. A security layer is applied to the audio signal within the portable device (e.g., by encrypting the audio signal), so that only authorized entities may access the audio signal. The audio signal is then outputted from the portable device to an external computer, which can remove the security layer to access the audio content within the audio signal. Methods, microphones, and processors are provided for processing sound waves. An optical pulse train is emitted through the sound waves, so that the optical pulse train is modulated by the sound waves. The modulated optical pulse train is then sensed, and in response, a modulated electrical pulse train is generated. An audio signal representing the sound waves is then generated based at least in part on the modulated electrical pulse train. Methods, microphones, and processors are provided for processing sound waves. The sound waves are detected with a portable device (such as a microphone), and an audio signal representing the sound waves is generated. The portable device is selectively activated and deactivated in response to remote signals.

    • Systems and methods for improving the signal to noise ratio for audio input in a computing system are provided. Signal to noise ratio improvements are enabled for an input audio signal by incorporating a plurality of microphones into the PC environment, for example, to improve the processing of voice or speech input or other audio capture applications. In various embodiments, a plurality of microphones are spaced apart, e.g., attached to or within a PC housing, in such a way that noise from PC components can be “subtracted” or reduced from an input audio signal, which increases the signal to noise ratio and improves audio processing accuracy. The “subtraction” or reduction techniques applied by the present invention are unique to the PC environment wherein different noises having particular characteristics can be identified, including, but not limited to, rattle of device components, fan noise and disk noise.
    • 提供了用于提高计算系统中音频输入的信噪比的系统和方法。 例如,通过将多个麦克风并入PC环境中来为输入音频信号启用信噪比改进,以改善语音或语音输入或其他音频捕获应用的处理。 在各种实施例中,多个麦克风间隔开,例如附接到PC壳体或其内部,使得来自PC组件的噪声可以从输入音频信号中“减去”或减小,这增加了信噪比 比例,提高音频处理精度。 本发明应用的“减法”或缩减技术对于PC环境是独特的,其中可以识别具有特定特性的不同噪声,包括但不限于设备部件的拨浪鼓,风扇噪声和磁盘噪声。

    • Camera and methods are provided for watermarking film content. A watermark, which can have information, such as a tracking message, is generated. The watermark preferably can be represented as correlated noise that cannot be visually noticed by a casual observer of the film content, but can later be extracted from the film content to obtain the embedded information, e.g., during a forensics study in a piracy investigation, to provide end-to-end asset tracking and management, or to prevent viewing of the film content. The watermark is optically applied to the optical image to generate a watermarked optical image, e.g., by absorbing light from selected regions within the optical image. The optical image may optionally be analyzed, in which case, the watermark can be applied to the optical image based on the analysis. Lastly, the photographic film is exposed to the watermarked optical image, thereby capturing the optical image and watermark on film. Camera and methods are provided for modifying film content. An optical image is temporally dividing into first and second optical image segments. The first optical image segment is analyzed, and the second optical image segment is modulated based on the analysis, e.g., by absorbing light from selected regions within the second optical image segment. A reflective MEMS array can be used to advantageously provide high resolution modulation of the second optical image segment. Photographic film is then exposed to the modulated optical image segment. As a practical example, an optical image can be watermarked, or an optical image can be corrected prior to exposure of the film using this technique.
