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.
Claims13
A method in an electronic picture quality monitoring system, comprising:
- receiving, by the electronic picture quality monitoring system, video data from a remote source;
- generating, by the electronic picture quality monitoring system, video for presentation on a presentation device based on the video data received from the remote source, the generated video including a plurality of video frames;
- outputting, by the electronic picture quality monitoring system, the generated video to the presentation device for display on the presentation device;
- while outputting the generated video to the presentation device, sending, by the electronic picture quality monitoring system, indications of which video frames of the plurality of video frames are currently being displayed on the presentation device;
- in response to the sending indications of which video frames of the plurality of video frames are currently being displayed on the presentation device, receiving, by the electronic picture quality monitoring system, metadata regarding picture quality of the video frames of the plurality of video frames that are currently being displayed on the presentation device;
- and
- in response to receiving the metadata regarding picture quality of the video frames of the plurality of video frames that are currently being displayed on the presentation device, performing, by the electronic picture quality monitoring system, an action based on the received metadata that results in a corrective measure being taken to address the picture quality.
