摘要： Provided in embodiments of the present invention are a method and device for transmitting a high-definition video signal, comprising: isolating from the high-definition video signal a brightness signal and a chrominance signal, and, by using an analog signal transmission mode, using non-overlapping frequency hands to transmit respectively the brightness signal and the chrominance signal. The solution of the present invention employs the analog signal transmission method, utilizes independent frequency bands to transmit respectively the brightness signal and the chrominance signal, and ensures that the brightness signal and the chrominance signal do not affect each other, thus ensuring video quality and timeliness of the high-definition video signal when transmitted over a long distance.

摘要： The present technology relates to a reproduction device, a reproduction method, and a recording medium that enable graphics with an appropriate brightness to be displayed on a video having a wide dynamic range of brightness. A recording medium, on which the reproduction device of one aspect of the present technology performs reproduction, records coded data of an extended video that is a video having a second brightness range that is wider than a first brightness range, brightness characteristic information that represents a brightness characteristic of the extended video, and graphics data that is superimposed on the extended video and that has the first brightness range. The reproduction device converts a first pixel value of the graphics to a second pixel value in the brightness characteristic of the extended video represented by the brightness characteristic information, the second pixel value representing brightness that is equivalent to brightness represented by the first pixel value in a brightness characteristic of the graphics, and synthesizes the extended video, the extended video being obtained by decoding the coded data, together with graphics having the second pixel value. The present technology can be applied to players that reproduce contents.

摘要： A method of creating a video stream is provided. The method includes receiving into non-transitory memory first and second video streams. The first video stream is different from the second video stream. Each video stream includes a series of video images each having a plurality of pixels. Each pixel has a luminance component and two chrominance components. The method includes converting, using a computing processor, the luminance component of a first pixel in a first image of the first video stream into an opacity component. The method also includes combining, using the computing processor, the opacity component of the first pixel and color components of a second pixel into an output pixel. Finally, the method includes outputting an output video stream comprising the output pixel.

摘要： An image decoder includes a base layer to decode at least a portion of an encoded video stream into a first image having a first image format. The image decoder can generate a color space prediction by scaling a color space of the first image from the first image format into a color space corresponding to a second image format. The image decoder includes an enhancement layer to decode the encoded video stream to generate a second image in the second image format based, at least in part, on the color space prediction.
