Patent ID: 7050113

Claim:
An apparatus for scaling video data, comprising: first horizontal scaler for scaling a frame of a decoded digital video stream by a first scale factor, said first scale factor resulting in a scaled video stream with a first horizontal to vertical aspect ratio; second horizontal scaler for scaling digital graphic data by a second scale factor different from said first scale factor, said second scale factor resulting in scaled graphic data with a second horizontal to vertical aspect ratio, wherein said second horizontal to vertical aspect ratio is different from said first horizontal to vertical aspect ratio; compositing blender for digitally combining the scaled video stream from said first horizontal scaler with the scaled graphic data from said second horizontal scaler; and digital display encoder attached to said compositing blender for converting the digital composited blend to analog form for display on a display device having said second horizontal to vertical aspect ratio; and wherein when displayed, said scaled video stream in said first aspect ratio utilizes fully one dimension of said display device, with blank areas in the other dimension of said display device, and said scaled graphic data in said second aspect ratio is scaled to extend beyond said scaled video stream on said display device to fill the blank areas on said display device.
