Patent ID: 7362330

Claim:
A computer-implemented method comprising: identifying a down point location; determining one or more start point fractional values based upon the down point location; selecting one of the start point fractional values for a view screen segment, wherein the selecting further comprises: identifying a view screen segment identifier that corresponds to the view screen segment; determining a last bit value of the view screen segment identifier; selecting a fifty percent start point fractional value in response to determining that the last bit value is one; in response to determining that the last bit value is zero, determining a second to last bit value of the view screen segment identifier; selecting a twenty five percent start point fractional value in response to determining that the second to last bit value is one; in response to determining that the second to last bit value is zero, determining a third to last bit value of the view screen segment identifier; and selecting a twelve and one-half percent start point fractional value in response to determining that the third to last bit value is one; computing a view screen segment start point using the selected start point fractional value; generating image values corresponding to the view screen segment starting at the view screen segment start point; and displaying the image values on a view screen.
