On-Screen Display Specification
|Publication Date:||1 July 2006|
This standard, CEA-799-A, specifies syntax and semantics for bitmapped graphics data typically used for on-screen display (OSD). CEA-799-A is applicable whenever it is necessary to specify a standard method for delivery of bitmapped graphics data. The pixel formats include optional alpha-blend and transparency attributes to support composition of graphics over analog or digitally decoded video within the display. In CEA-799-A, the source of the bitmapped graphics data is called the OSD Producer and the device receiving and processing the data is called the OSD Consumer. CEA-799-A is designed such that it may be referenced in part or in whole.
