Embodiment Construction

[0029] The disclosed embodiments are best understood by reference to the figures and detailed description set forth herein. Various embodiments are described below with reference to the figures. However, those skilled in the art will readily appreciate that the detailed description given herein with reference to these figures is for explanatory purposes, as the disclosed methods and apparatus extend beyond the described embodiments.

[0030] Definition of terms:

[0031] Aspect Ratio: The aspect ratio describes the proportional relationship between the width and height of a surface. The aspect ratio of an image frame refers to the ratio of the width of the image frame to the height of the image frame. For a monitor screen, the aspect ratio is specifically the ratio of the width of the monitor screen compared to its height. For example, the aspect ratio of the display screen of a standard definition television is 4:3 and that of a high definition television is 16:9.

Abstract

The present disclosure provides a method and apparatus for processing a video signal for display. The method and apparatus includes a merger configured to merge a plurality of unused regions to form a merged display region based on a determination of a difference between an aspect ratio of the generated display and an aspect ratio of the first content. The method and apparatus merge a plurality of unused regions to generate an output video signal having the merged region and a first content region associated with a first content. A merger merges the plurality of unused regions by at least partially moving the first content region toward at least one edge of the output video signal. The plurality of unused regions is merged by scaling down the size of the first content region associated with the first content.

Description

technical field [0001] The present disclosure generally relates to video signal processing, and more particularly, the present disclosure relates to methods and apparatus for processing video signals for displays. Background technique [0002] Advances in video processing technology have enabled the generation of video and / or image content with different aspect ratios such as 4:3, 16:9. Furthermore, current display technology provides display screens with different aspect ratios. For example, the aspect ratio of the display screen of a standard definition television is 4:3 and that of a typical high definition television is 16:9. [0003] When the aspect ratio of content, such as an image or video, is different from that of the display screen on which the content is displayed, multiple letterbox or pillarbox areas become visible on the display screen. Typically, these areas are located on two opposite sides of the screen's content display area. For example, letterbox area...
