Apparatus for improving the presentation of graphics data on a television display

A circuit utilized to convert a selected portion of graphics data generated for a computer display into video data for presentation on a selected portion of a television display comprising:

• a first data path for transferring graphics data from a source of graphics data to a television display without changing the size of the data, and
• a second data path for transferring graphics data from the source of graphics data to a television display while selectably changing the size of the data,
• the second data path including circuitry for selecting a portion of the television display on which to present the selected data transferred by the second data path, and
• zooming circuitry for enlarging data transferred by the second data path to fill the selected portion of the television display.

A method for converting a selected portion of graphics data generated for a computer display into video data for presentation on a selected portion of a television display without requiring processor manipulation of pixels of the selected portion of graphics data comprising the steps of:

• transferring graphics data from a source of graphics data to a television display via a first data path without changing the size of the data, and
• transferring graphics data from the source of graphics data to a television display via a second data path while selectably changing the size of the data,
• selecting a portion of the television display on which to present the selected data transferred by the second data path, and
• enlarging data transferred by the second data path to fill the selected portion of the television display.
