Title:

Method for Using the Picture In Picture Window to Zoom Digital Images

Abstract:

The picture in picture (PIP) window can be used to dynamically magnify (zoom) audio visual data from the underlying main picture.

Description of the Invention:

1.      Zoom windows typically magnify a portion of an audio-visual (A V) image, either in a separate window or to fill the entire main window. Currently, Set-top boxes (STB) do not permit zooming of A V images.

2.      Using the picture in picture (PIP) window permits a viewer to dynamically zoom portions of the A V image by moving, dragging, the PIP window over the main window and magnifying the area beneath it. The PIP window may be sized by the viewer, so that it covers a portion of the main picture. The magnified area would be a rectangular area of the main window, of the same shape, but smaller (by the level of magnification) that the PIP window, directly beneath the PIP window. The level of magnification may be specified (2x, 4x, etc.). Using higher magnification decreases the size of the magnified area.

3.      This invention could be implemented on the Apollo STB architecture currently under development in DP A. Using the Broadcom 7030 with its display and graphics capabilities, all that would be required is additional software.
