  • Patent number: 12500997
    Abstract: Methods and systems for producing a video stream. A first user is authenticated. A first primary video stream is captured showing the first user and comprising a first primary authentication video part. A fourth primary video stream is captured, visually showing the first user from a different point of view, comprising a fourth primary authentication video part. One-way functions of the first and fourth primary video streams are calculated, each being calculated using the respective primary authentication video part. The produced video stream is automatically produced based on the first primary video stream. For each of the one-way function outputs, the output is embedded into a least one of the video streams so that the embedding depends on content in a video stream which is not the same as the video stream into which the embedding is made. The output is stored and/or publicly published.

  • Publication number: 20250324017
    Abstract: Method, system and computer program product for providing a second digital video stream. In a collecting step, a first and a second primary digital video stream are collected from at least two different digital video sources. In a first production step, a first produced video stream is produced based on the first and second primary streams. In a second production step, the second stream is produced based on the first produced stream and also based on the first and second primary streams. In the second production step, the first and second primary streams are time-delayed so as to time-synchronise them with the first produced stream, taking into consideration a latency of the first produced stream resulting from the first production step, the second produced stream being produced based on the time-delayed first and second primary streams.

  • Publication number: 20250259654
    Abstract: Method, system and computer program product for providing an output digital video stream enhanced by real-time analysis. A primary digital video stream is continuously captured and analyzed locally to detect initial events or patterns, generating a first control parameter with a first delay. A more complex image or audio analysis is performed remotely, identifying additional events and generating a second control parameter with a longer delay. The second parameter is applied to a later point in the stream, allowing seamless, real-time modification without playback interruption. The modified video stream is delivered to clients as a final output. The first primary digital video stream is continuously captured by a camera local to the participating client and a computer device performing the analysis and application of the first production control parameter. The second analysis is performed by a computer device remote to the computer device applying the first production control parameter.

  • Publication number: 20250193463
    Abstract: Methods and systems for generating an output digital video stream. A real-time primary digital video stream is continuously captured and analyzed to detect events or patterns. A first analysis identifies a first event, establishing a first production control parameter after a short delay. A second image or audio analysis, detecting a second event, establishes a second production control parameter after a longer delay. Both control parameters modify the primary video stream, ensuring that adjustments based on the second parameter are applied without introducing additional delay. This produces a modified digital video stream, continuously provided to at least one client. The primary video stream is captured locally, with the first analysis and initial modifications performed locally, while the second analysis is performed remotely. This approach enables real-time content modification without delaying the output stream.

  • Patent number: 12262069
    Abstract: Methods, systems, and computer program products for providing a shared digital video stream. A first and a second digital video stream are collected. The shared stream is produced based on the first stream so that the first source is visible in the shared stream, but so that the second source is not visible in the shared stream. The first and/or second stream are analysed to detect a trigger, based on detection of a predetermined image and/or audio pattern, the trigger being a detected gazing or a gesture. The shared stream based on the second stream and/or based on the first source but with at least one of a different cropping, a different zooming, a different panning, or a different focus plane selection. The output stream is provided to a consumer.

  • Publication number: 20250054518
    Abstract: Method, system and computer program product for providing an output digital video stream, comprising: continuously collecting a real-time first primary digital video stream; performing a first digital image analysis of the first primary digital video stream to identify at least one first event or pattern, resulting in a first production control parameter being established at a first time delay in relation to a time of occurrence of said first event or pattern in the first primary digital video stream; applying said first production control parameter to said first primary digital video stream, resulting in the first primary digital video stream being modified without being delayed by said first time delay, so as to produce a first produced digital video stream; and continuously providing said output digital video stream based on said first produced digital video stream.

  • Patent number: 12184908
    Abstract: Method, systems and computer program product for providing a shared digital video stream. A first and a second digital video stream are collected. The shared stream is produced based on said first stream, so that the first source is visible in the shared stream, but so that the second source is not visible in the shared stream. A latency with respect to the first and the second digital video stream is deliberately introduced. The first and/or second stream are analyzed in to detect a trigger, based on detection of a predetermined image and/or audio pattern. The shared stream is produced based on the second stream and/or based on the first source, but with at least one of: a different cropping, a different zooming, a different panning or a different focus plane selection.
