    Abstract: A receiving device performs an action that results in a corrective measure being taken to address a picture quality issue detected in real time in the frames currently being displayed on a television or other device. The receiving device or a remote system compares indications of video frames currently being displayed to stored video frames for that program to detect macroblocking or a frozen video frame. The macroblocking or a frozen video frame may also or instead be detected by image analysis of the frames currently being displayed. If macroblocking or a frozen video frame is detected in the frames currently being displayed, the set-top box may switch to an alternative video source, change to a standard definition channel broadcasting the same video program or perform other corrective actions.

    Abstract: An image sensor of a camera configured with a diffraction grating is used to capture a diffraction image of an image rendering surface of a display device, for example, while a target image is being rendered on the image rendering surface of the display device. The diffraction image of the image rendering surface of the display device is analyzed to obtain measurements of native display capabilities of the display device. Display capability data is transmitted to a display management module for the display device. At least a portion of the display capability data is generated from the measurements of native display capabilities of the display device that are obtained from analyzing the diffraction image of the image rendering surface of the display device.

    Abstract: Various arrangements for testing video decoder device functionality are presented. A video frame decoded by a video decoder device under test may be received. The received video frame may be segmented into a plurality of blocks. A first value may be calculated for a first block of the plurality of blocks of the received video frame using pixel values of pixels present within the first block. The first value may be compared to a first reference value. The first reference value may correspond to a first reference block of one or more reference frames. Video decoder functionality of the video decoder device may be determined to be functional at least partially based on comparing the first value to the first reference value.

    Abstract: A waveform monitor for generating a modified image from an original image includes a measuring system to select luminance frequency values of the original image that are above a first and a second threshold. A modifier changes selected pixels of the original image that fall above the first and second thresholds. In some embodiments these changed pixels are given a false color as color markers to indicate DOF and areas of sharpest focus of the original image. Methods of modifying images in this manner are also described.
