In roku Design Guidelines there is specified this:
The overhang is the application-branded area at the top of each screen (objects in the overhang are inactive and cannot be selected by the user). The suggested
maximum Overhang height is 83 pixels for SD and 124 pixels for HD. The enforced maximum Overhang height is 92 for SD and 138 for HD.
Between the suggested maximum height and the enforced maximum height is a transition area in which application developers should alpha blend their Overhang art into the screen background. Art rendered in the Overhang transition area (83 - 92 px for SD and 124 - 138 px for HD) will be rendered over by the Filter Banner, Modal Dialogs, and other native UI widgets. Application developers should not assume that the art in the Overhang transition zone will always be viewable by the end user.
