Abstract
In a video processing system, such as e.g. a set top box or a BD player wherein in a merger video can be merged with one or more overlays a video/overlay pixel indication (A) is encoded in one or more of the least significant bits of one or more of the color components in the video signal. The video signal is transmitted over the interface between VPS and display. The display subject the image to an adaptation. This adaptation is performed dependent on the video/overlay pixel indication (A).
Claims19
An apparatus for decoding an HDR video signal merged from more than one source signal, the apparatus comprising:
- a reader device having an input for receiving the HDR video signal, the reader device for (i) reading at least one or more least significant bits of one or more color components of the received HDR video signal for a pixel and (ii) generating one or more values from the read at least one or more least significant bits, wherein the generated one or more values indicate a merging property for the pixel, the merging property being indicative of a property of a merging in the received HDR video signal of one or more overlay signals with a video image signal for that pixel;
- and
- an adapter device, communicatively coupled to the reader device, for adapting, via one or more dynamic range adaptation, a pixel value in the received HDR video signal in dependence on the generated one or more values that indicate a-said merging property for a respective pixel, the adapter device having an output for outputting an adapted HDR video signal, in which (i) a dynamic range adaptation of video image pixels merged with one or more overlay in the received HDR video signal is different from (ii) a dynamic range adaptation of non-merged video image pixels in the received HDR video signal, to be rendered on a display device.
A method of decoding an HDR video signal merged from more than one source signal, the method comprising:
- reading, via a reader device having an input for receiving the HDR video signal, at least one or more least significant bits for one or more color components of the received HDR video signal for a pixel and generating one or more values from the read at least one or more least significant bits, wherein the generated one or more values indicate a merging property for the pixel, the merging property being indicative of a property of a merging in the received HDR video signal of one or more overlay signals with a video image signal for that pixel;
- and
- adapting, via an adapter device communicatively coupled to the reader device and via one or more dynamic range adaptation, a pixel value in the received HDR video signal in dependence on the generated one or more values that indicate said merging property for a respective pixel, wherein adapting further includes outputting an adapted HDR video signal, in which (i) a dynamic range adaptation of video image pixels merged with one or more overlay in the received HDR video signal is different from (ii) a dynamic range adaptation of non-merged video image pixels in the received HDR video signal, to be rendered on a display device.
An apparatus for encoding a video signal, the apparatus comprising:
- a merger device having an input for receiving an HDR video image signal, the merger device for merging the HDR video image signal with one or more overlay signals to form a merged video signal;
- a processor, operatively coupled to the merger device, for generating one or more values indicating, for a pixel in the merged video signal, a merging property indicative of a property of the merging in the HDR video image signal with the one or more overlay signals for that pixel in the merged video signal;
- and
- an encoder, operatively coupled to the merger device and the processor, for encoding for said pixel said one or more values in one or more least significant bits of one or more color components of a pixel value for the pixel in the merged video signal,
- wherein the merged video signal encoded with said one or more values enables (i) a dynamic range adaptation of video image pixels merged with one or more overlay in the merged video signal to be different from (ii) a dynamic range adaptation of non-merged video image pixels in the merged video signal, in dependence on the one or more values that indicate said merging property for a respective pixel, to be rendered on a display device.

- encoding, via an encoder operatively coupled to the merger device and the processor, for said pixel said one or more values in one or more least significant bits of one or more color components of a pixel value for the pixel in the merged video signal, wherein the merged video signal encoded with said one or more values enables (i) a dynamic range adaptation of video image pixels merged with one or more overlay in the merged video signal to be different from (ii) a dynamic range adaptation of non-merged video image pixels in the merged video signal, in dependence on the one or more values that indicate said merging property for a respective pixel, to be rendered on a display device.
