Abstract:
1. An apparatus comprising: a first circuit configured to (i) receive a first decoded data signal having a first chroma format from a video decoder circuit and a second decoded data signal having a second chroma format from a subpicture decoder circuit and (ii) generate a first composited data signal and a second composited signal in response to said first decoded data signal and said second decoded data signal, wherein said first circuit comprises (i) a line splitter circuit configured to separate said second decoded data signal into a first intermediate signal and a second intermediate signal, (ii) a first compositing circuit configured to generate said first composited data signal by compositing said first decoded data signal and said first intermediate signal and (iii) a second compositing circuit configured to generate said second composited data signal by compositing said first decoded data signal and said second intermediate signal; and a second circuit configured to generate a first composited output signal having said first chroma format in response to said first and said second composited data signals, wherein said second circuit comprises a decimator circuit configured to generate said first composited output signal in response to said first composited data signal and said second composited data signal.
