In aspects of personal content managed during extended display screen recording, a screen recording system includes a wireless device that provides digital image content for display on an extended display device, and a screen recording session on the wireless device captures the digital image content and audio data. The wireless device implements a content control module that can determine the screen recording session would capture personal content associated with a user of the wireless device. The content control module can initiate a private screen review mode in which the personal content is displayable on a display screen of the wireless device and is prevented from visual display on the extended display device. The content control module can also generate a shareable screen recording that includes the audio data and the digital image content displayed on the extended display device, without including the personal content.

Various embodiments of apparatus, systems and/or methods are described for independently controlling an audio stream relative to a video stream in audio trick mode. In one example, an audio stream and a video stream is received, where the audio stream comprises frames that correspond to corresponding frames of the video stream. The audio and video streams are played from a first time to a second time at a first speed. An input to time shift the audio stream independent of the video stream is received, and after receiving such, the audio stream is time shifted to the first time. Then, the audio stream may be replayed from the first time to the second time at a second speed different from the first speed.

A recording device includes a video encoding unit configured to compress and then encode video data pieces by a first unit of data, an audio encoding unit configured to compress and then encode audio data pieces in a second unit of data, and a multiplexing unit. The multiplexing unit selects the audio data pieces by the second unit of data from the audio data pieces in such a way that an amount of temporal shift between the respective video data pieces and the audio data pieces corresponding to the respective video data pieces will become less than or equal to a time length of the second unit of data and then multiplexes the selected audio data pieces with the video data.

The processor obtains a third pixel value and a second pixel value of the display. The processor determines a desired pixel value range that exceeds the second pixel value of the display. The processor obtains a threshold between the third pixel value of the display and the second pixel value of the display. The processor obtains a function mapping the desired pixel value range to a range between the threshold and the second pixel value. The processor applies the first function to an input image prior to displaying the input image on the display. The display presents the image. Upon recording the presented image, the processor determines a region within the recorded image having a pixel value between the threshold and the second pixel value. The processor increases dynamic range of the recorded image by applying an inverse of the function to the pixel value of the region.

A data acquisition and recording system (DARS) and viewer for mobile assets that includes a data encoder, onboard data manager, and at least one local memory module. DARS processes video data from at least one 360 degree camera and stores a compressed record of the data at least once per second in the local memory module. DARS is designed to run in near real-time mode, storing a full record comprising five minutes of data to a remote memory module every five minutes, and in real-time mode, streaming video data to the remote memory module by uploading a record of data at least once per second and up to once every tenth of a second. Remotely located users can view video, audio, and data in various view modes through a web browser or virtual reality device, which provides for quicker emergency response, validate the effectiveness of repairs and rerouting, and monitor crew performance and safety.

A processor performing postprocessing obtains an input image containing both bright and dark regions. The processor obtains a threshold between a first pixel value of the virtual production display and a second pixel value of the virtual production display. The processor modifies the region according to predetermined steps producing a pattern unlikely to occur within the input image, where the pattern corresponds to a difference between the original pixel value and the threshold. The processor can replace the region of the input image with the pattern to obtain a modified image. The virtual production display can present the modified image. A processor performing postprocessing detects the pattern within the modified image displayed on the virtual production display. The processor calculates the original pixel value of the region by reversing the predetermined steps. The processor replaces the pattern in the modified image with the original pixel value.
