  • Patent number: 11670147
    Abstract: The present invention relates to a method and apparatus for processing video image data, so as to apply different types of processing to different aspects of video image data. A detection process is arranged to detect a item, object or event appearing or occurring in a scene being viewed by an image device. An image data process is responsive to the detection of the object or event and to control information to process the image data for a portion of the scene where the object or event appears or occurs, differently from the processing of the image data associated with the rest of scene. For example, the object may be a person's face, and the face image data may be processed to produce high resolution data, the rest of the scene being provided in low resolution. This saves on processing, transmission and storage.

  • Patent number: 11606615
    Abstract: An interactive user interface, such as a remote terminal user interface, is compressed prior to transmission to a video client. The compression may be performed independently of any other video that may be simultaneously transmitted to the video client. At the client side, two compressed video streams (remote user interface and video content) may be decompressed independently of each other. In some cases, technology already existing in some client devices, such as picture-in-picture (PiP) capability, may be leveraged to decompress the received compressed remote user interface without needing to modify the hardware of those client devices.

  • Patent number: 11601668
    Abstract: A system and method are provided for inter-ceding video in which encoder and decoder memory requirements associated with storage of motion information related to collocated coding units is reduced. In some embodiments motion information related to only a single collocated coding unit may be stored at the encoder and decoder. In operation, if the encoder determines that motion information for a current coding unit should replace the currently stored motion information for the currently stored motion information for the collocated coding unit, then the encoder can replace the motion information at the encoder and transmit an indicator with the current coding unit to signal to the decoder that the motion information currently stored should be updated or replaced with the motion information associated with the current coding unit.
