Video Compensation Or Correction Patents (Class 386/264)
  • Patent number: 10992970
    Abstract: In order to reduce the large volume of data transmitted over a network, immersive videos are frequently represented by a multiple versions, each version being optimised in terms of quality for a point of view on the immersive video, the immersive video parts not representing the point of view for which the version was optimised being of lower quality. In this context, when a user using suitable viewing equipment views the immersive video, he must change version whenever he changes point of view. Each version is generally stored on a server relatively distant from the viewing equipment, which may give rise to latencies in the reception of a new version following a change of point of view. This latency time is reduced by allowing a node in the intermediate network between the server and the viewing equipment to transmit each version to the equipment in place of the server.

  • Patent number: 10210549
    Abstract: The present application discloses a method for providing promotion content. A server provides to a client device media content and a sequence of closed caption (CC) messages that are synchronized with the media content. Two consecutive CC messages are separated by a blank duration that is marked by a blank mark and lasts for a predetermined length of time. The client device is configured to detect the blank mark and generate a request for promotion content that includes at least a user identification for identifying a user of the client device. Upon receiving the promotion content request, the server determines user preferences associated with the user identification, and further identifies a promotion content item according to the user preferences. The promotion content item is provided to the client device for concurrent display with the media content during the blank duration between the corresponding two consecutive CC messages.

  • Patent number: 10109315
    Abstract: A computer implemented method for automatic presentation of delayed video. During normal operation real-time video feed is sent to a digital screen for presentation and is also sent to memory for storage. When a delay trigger is issued, the system either freezes the frame presented in that instance or stores a time indicator. The system then monitors delay time and, when the delay time is reached, the system starts fetching frames from the memory, starting either from the frame immediately following the frozen frame or from the frame that was stored at the time indicator, and sends these frames to the digital screen for presentation. The system then monitors delay period and, when the delay period arrive, the system reverts to normal mode wherein real-time video feed is sent to a digital screen for presentation and is also sent to memory for storage.

  • Patent number: 8611691
    Abstract: A method for mitigating image distortions induced by optical wave propagation through a random media (e.g., atmospheric turbulence or volume of water) from a stream of video data provided by a single shortexposure image sensor is described. The method is based on the two following sequential steps: (1) enhancement of the raw video stream and (2) fusion of the enhanced stream using the lucky region fusion (LRF) technique. The first step enhances features of the raw image stream the LRF method success is based on and especially mitigates the effect of low light level, aerosol pollution, dust, haze, and other deteriorating factors. The second step, fusion of the enhanced stream, is realized by sequentially merging image regions with highest quality within a temporal buffer into a single image before sliding the temporal window forward. The process is continuously repeated in order to generate a stream of fused images.

  • Patent number: 8346052
    Abstract: In an HDMI-connected AV system, bidirectional data transmission between two devices is implemented at low cost. An audio amplifying device serving as an HDMI source and a display device as an HDMI sink are connected additionally using an auxiliary transmission path such as IEEE 1394, so that the data received by the display device 3 from another device is transmitted to the audio amplifying device 2 over the auxiliary transmission path. In this setup, the display device 3 generates a CTS based on a clock regenerated by ACR and on a TMDS clock received from the audio amplifying device 2 via the HDMI, and transmits the CTS over the auxiliary transmission path along with a frequency dividing ratio N. The audio amplifying device generates an audio signal clock from the CTS and N thus received.
