Transmission configuration indication, error detection and recovery by temporal signal interpretation

A transmission configuration and/or configuration errors and recovery may be determined or implemented by temporal interpretation of one or more signals. A transmitter may interpret one or more signals a first way during one or more time windows and a second way during one or more other time windows. Video resolution may be indicated in a V-by-One® interface by temporal interpretation of HPD and/or CDR lock. Transmission format may be indicated before or after transmission begins. Transmitter configuration error detection and recovery may be implemented by temporal interpretation. A transmitter may transmit data in an assumed/default format. A receiver may indicate the assumed transmission format is incompatible with the receiver configuration. A receiver may indicate a compatible transmission format, for example, based on timing or pulsing transitions in a temporally repurposed signal. A transmitter may respond to the repurposed signal indication by transmitting a different (e.g., compatible) format.

VIDEO ANALYTICS SYSTEM

A video monitoring system can include multiple collectors to receive video beacon data from multiple video monitoring interface modules. At least one beacon stream is connected to receive data from multiple collectors. A processing module receives the beacon stream and provides a real-time event stream used for real-time data analysis and a video view stream used for long-term data analysis.

VIDEO PLAYING

A method of video playing is provided. An implementation solution is: obtaining a video playing address list from a video management server, where the video playing address list includes playing links of real-time video streams of a plurality of monitoring cameras; obtaining the real-time video streams of the plurality of monitoring cameras from the video management server according to the video playing address list so as to be played on a screen; obtaining a historical video stream of at least one of the monitoring cameras from a video storage server so as to be played on the screen in response to detecting fault information which indicates that the real-time video stream of the at least one of the monitoring cameras cannot be played; and recording the fault information, where the fault information includes the playing link of the real-time video stream of the at least one of the monitoring cameras.

Frozen image detection
11627305 · 2023-04-11 · ·

Aspects of the disclosure provide for a method. In some examples, the method includes receiving a video stream comprising multiple frames, analyzing the video stream to compare data values representing an image pixel at a specified location in a first of the frames to data values representing an image pixel at the specified location in a second of the frames, determining that the video stream is frozen responsive to the data values representing the image pixel at the specified location in the first of the frames being the same as the data values representing the image pixel at the specified location in the second of the frames, and taking action responsive to determining that the video stream is frozen.

Automatic offering and switching to a higher quality media stream
11627368 · 2023-04-11 · ·

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for automatically offering and switching to outputting to a higher quality media stream in place of a lower quality media stream. An example embodiment operates by performing automated content recognition (ACR) on a first media stream thereby determining a first content item having a first quality level in the first media stream. The embodiment determines that the first content item matches a second content item having a second quality level in a second media stream at a content source, wherein the second quality level is higher than the first quality level. The embodiment requests the second media stream from the content source. The embodiment receives the second media stream from the content source. The embodiment then outputs the second media stream in place of the first media stream.

Testing rendering of screen objects
11647249 · 2023-05-09 · ·

The present disclosure relates to methods and devices for testing video data being rendered at or using a media device. A plurality of video frames to be rendered is received, each frame comprising one or more primary screen objects and at least one further screen object. The received frames are rendered at or using the media device wherein the at least one further screen object is superimposed on the one or more primary screen objects of a given frame during rendering. The rendered frames are provided to a data model. Extracted metadata indicating the presence or absence of further screen objects in the rendered video frames is the output of the data model. The data model is also provided with original metadata associated with the video frames prior to rendering. The rendering of each further screen object is then tested based on the original metadata and extracted metadata relating to a given video frame. The disclosure also extends to associated methods and devices for generating training data for testing rendering of video frame and training a data model using the training data.

Handling exceptions reported by media device meters

Apparatus, systems, articles of manufacture, and methods are disclosed for handling exceptions reported by media device meters. An example apparatus includes a static display detector to determine whether current measurements for a media presentation device at a time corresponding to an exception reported by a media device meter indicate the media presentation device was in a static display state at the time corresponding to the exception. The example apparatus includes a muted viewing detector to determine whether the media presentation device was in a muted viewing state at the time of the exception based on an audio level associated with the media presentation device, and an exception modifier to determine whether to modify the exception based on whether the media presentation device was in the static display state and whether the media presentation device was in a muted viewing state at the time of the exception.

Error de-emphasis in live streaming

A Reductive Edging device and computer program product. The Reductive Edging device has a processor, memory coupled to the processor and non-transitory instructions embedded in the memory that when executed by the processor causes the device to perform a method for reductive edging. The method includes, prior to sending a media segment to a client device, performing error de-emphasis operations and sending information associated with error de-emphasis.

WRITE CONFIRMATION OF A DIGITAL VIDEO RECORD CHANNEL

Systems, methods, and computer program products to perform an operation comprising receiving a first unit of video data on a first input/output (I/O) channel, of a plurality of I/O channels of a digital video recorder, computing a first value by applying an error-detecting function to the first unit of video data, attempting to write the first unit of video data to a storage location of a storage device communicably coupled to the digital video recorder, computing, after attempting to write the first unit of video data, a second value by applying the error-detecting function to a data stored at the storage location of the storage device, and upon determining that the first and second values are not equal, storing an indication that the first unit of video data was not successfully written to the storage location of the storage device.
