Abstract: Methods, devices, systems and/or storage media for video and/or audio processing. An exemplary method of controlling a display device includes receiving an executable file and/or code via a network interface, receiving video data via a serial digital interface, executing the executable file and/or code on a runtime engine, processing the video data based at least in part on the executing to produce processed video data and displaying the processed video data. Other exemplary technologies are also disclosed.

Abstract: 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.

Abstract: 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.

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.

Abstract: A method and apparatus is presented for decoding an encoded streaming media file and outputting the decoded streaming media file directly in the frame buffer of a driver, thereby eliminating the need for intermediate buffers for audio, video, and print devices. The method provides the capability to capture audio, video, and/or print (and metadata) at a point and apply digital rights management to the data from the point of capture to the point of rendering. The invention works with any rendering technology that uses frame buffers, such as digital light processing (DLP) device, liquid crystal displays (LCDs), and MEM (Micro-electro-mechanical) imaging devices.

Abstract: An image capturing device is capable of capturing and encoding image data so as to output a streaming media file from the device. Vector information derived from the captured image data may be altered to change, i.e., the frame capture rate of subsequent image data, according to frame resolution requirements.
