Embodiment Construction

[0035] In the following description, specific details are set forth in order to provide those skilled in the art with a more thorough understanding. However, well-known elements may not be shown or described in detail in order to avoid unnecessarily obscuring the disclosure. Accordingly, the description and drawings are to be regarded in an illustrative rather than a restrictive sense.

[0036] Example embodiments are provided for systems, devices, and methods useful in video delivery pathways. Metadata is written into the video data and transmitted with the video data through the video delivery pipeline. Metadata may be useful, for example, for directing downstream devices in processing video data and / or directing video playback on a display. The display may be, for example, a flat panel display (eg, LCD, LED, OLED, high dynamic range, or plasma display) that may be provided in a television, computer monitor, laptop, cell phone, or handheld mobile device, etc., Or any othe...
