Abstract

A UHD display presents HD video in the native resolution of HD, leaving some portions of the UHD display unused for presenting the HD video. Ancillary information received, for example, in real time with the HD video or in parallel with the HD video over the Internet is presented in the unused portions of the UHD display along with the HD video.

First claim

What is claimed is:

1. Assembly comprising:
ultra high definition (UHD) display configured for presenting video in 2160 pixel lines or 4320 pixel lines;
processor configured for controlling the UHD display; and
computer readable storage medium bearing instructions executable by the processor to:
present high definition (HD) video on the UHD display using at least 1440 of the pixel lines and no more than 1920 of the pixel lines, wherein portions of the display do not present HD video when HD video is being presented elsewhere on the display; and
present ancillary information in the portions of the display that do not present HD video, the ancillary information being receivable from a source of TV signals or from the Internet in real time with the HD video, wherein the ancillary information is received from the source of TV signals along with the HD video in a common channel with the HD video.

2. The assembly of claim 1 , wherein the ancillary information is received from the Internet.

3. The assembly of claim 1 , comprising a user input device configured for communicating with the processor to input first and second user commands, the first user command being to present the HD video on the entire UHD display by upscaling the HD video, the second user command being to present the HD video on a portion of the UHD display and to present on the UHD display the ancillary information along with the HD video.

4. Assembly comprising:
ultra high definition (UHD) display configured for presenting video in 2160 pixel lines or 4320 pixel lines;
processor configured for controlling the UHD display; and
computer readable storage medium bearing instructions executable by the processor to:
present high definition (HD) video on the UHD display using at least 1440 of the pixel lines and no more than 1920 of the pixel lines, wherein portions of the display do not present HD video when HD video is being presented elsewhere on the display; and
present ancillary information in the portions of the display that do not present HD video, the ancillary information being receivable from a source of TV signals or from the Internet in real time with the HD video, wherein the ancillary information is configured for being ignored by non-UHD assemblies.

5. Method comprising:
receiving, at an ultra high definition (UHD) display characterized by a first resolution, high definition (HD) video characterized by a second resolution less than the first resolution;
presenting the HD video on the UHD display without upscaling the HD video to fill the entire UHD display to thereby render portions of the UHD display that do not present the HD video;
presenting ancillary information in the portions of the UHD display that do not present the HD video;
receiving a user command to upscale the HD video and fill the UHD display with the HD video;
responsive to the user command, upscaling the HD video to fill the UHD display; and
receiving the ancillary information from a source of TV signals along with the HD video in a common channel with the HD video.

6. The method of claim 5 , wherein the UHD display presents video in 2160 pixel lines or 4320 pixel lines and the HD video uses at least 1440 of the pixel lines on the UHD display.

7. The method of claim 5 , wherein the HD video uses at least 1920 lines of the UHD display.

8. The method of claim 5 , comprising receiving the ancillary information from the Internet.

9. The method of claim 5 , wherein the user command is a first command and is received from a user input device, the processor is configured for receiving from the user input device a second user command to present the HD video on a portion of the UHD display and to present on the UHD display the ancillary information along with the HD video.

10. Method comprising:
receiving, at an ultra high definition (UHD) display characterized by a first resolution, high definition (HD) video characterized by a second resolution less than the first resolution;
presenting the HD video on the UHD display without upscaling the HD video to fill the entire UHD display to thereby render portions of the UHD display that do not present the HD video;
presenting ancillary information in the portions of the UHD display that do not present the HD video;
receiving a user command to upscale the HD video and fill the UHD display with the HD video; and
responsive to the user command, upscaling the HD video to fill the UHD display, wherein the ancillary information is configured for being ignored by non-UHD assemblies.

11. An ultra high definition (UHD) display device comprising:
a UHD display configured for presenting non-UHD video in a native resolution of the non-UHD video, leaving some portions of the UHD display unused for presenting non-UHD video to establish unused display portions; and
a processor configured for controlling the UHD display to present demanded images, the processor configured for causing ancillary information received in real time with the non-UHD video or in parallel with the non-UHD video over the Internet to be presented in the unused display portions of the UHD display along with the non-UHD video, wherein
the processor being provided with executable instructions which when executed by the processor configure the processor for receiving a header indicating ancillary information may be presented along with the non-UHD video on the UHD display, the instructions when executed by the processor configuring the processor for, responsive to at least one data element in the header, presenting on the UHD display an interface allowing a user to select between presenting the non-UHD video full screen and presenting the non-UHD video partial screen along with the ancillary information.

12. The device of claim 11 , wherein the ancillary information is received from a source of TV signals along with the non-UHD video in a common channel with the non-UHD video.

13. The device of claim 11 , wherein the ancillary information is received from the Internet.

14. The device of claim 11 , comprising a user input device configured for communicating with the processor to input first and second user commands, the first user command being to present the non-UHD video on the entire UHD display by upscaling the non-UHD video, the second user command being to present the non-UHD video on a portion of the UHD display and to present on the UHD display the ancillary information along with the non-UHD video.

15. The device of claim 11 , wherein the ancillary information is configured for being ignored by non-UHD assemblies.

16. The method of claim 5 , comprising upscaling the HD video at least in part by interpolating first and second adjacent pixels having respective first and second pixel values in the HD video and inserting an extra pixel between the first and second pixels, the extra pixel having a value interpolated between the first and second pixel values.

17. The method of claim 5 , comprising receiving a user command to downscale HD video into an area of the UHD display that is less than an entire available display area of the UHD display.
