  • Patent number: 11948519
    Abstract: Visual safety is ensured when image switching takes place. When an image is switched by nonlinear reproduction, a display property is kept switched, during a transition display period, to a transition display property with a brightness level kept lower than a normal level, on the basis of pixel statistical information regarding the image. For example, an electro-optic conversion property is controlled to a transition property or the brightness level of a backlight is suppressed.

  • Patent number: 11895309
    Abstract: A transmission apparatus configured to mix, at a mixing rate, pixels of first video data with pixels of peripheral frames of the first video data and obtain second video data at a first frame rate. The mixing rate for each pixel of a frame of the first video data is based on a luminance value of the pixel. The second video data includes frames having a second frame rate lower than the first frame rate. The apparatus encodes the frames having the second frame rate to obtain a basic stream and encodes remaining frames of the second video data to obtain an extended stream, inserts information about the mixing rate into the basic stream and the extended stream in association with each frame, and transmits the basic stream and the extended stream into which the information about the mixing rate has been inserted.

  • Patent number: 11838564
    Abstract: Reception-side processing performed in a case where transmission of standard dynamic range video data and transmission of high dynamic range video data coexist in a time sequence is simplified. SDR transmission video data is converted into SDR transmission video data through dynamic range conversion. The SDR transmission video data is the one obtained by performing, on SDR video data, photoelectric conversion in accordance with an SDR photoelectric conversion characteristic. In this case, the conversion is performed on the basis of conversion information for converting a value of conversion data in accordance with the SDR photoelectric conversion characteristic into a value of conversion data in accordance with an HDR photoelectric conversion characteristic. A video stream is obtained by performing encoding processing on HDR transmission video data. A container having a predetermined format and including this video stream is transmitted.
