Claim 17:
18. The device of claim 13, wherein to perform the wide-angle mapping on the original predModeIntra to obtain the modified predModeIntra, the programming instructions, which when executed by the one or more processors, cause the device to:
set the modified predModeIntra to (the original predModeIntra+65) when all of the following are true:
a variable nW is greater than a variable nH,
the original predModeIntra is greater than or equal to 2, and
the original predModeIntra is less than (a variable whRatio>1)?(8+2*the variable whRatio):8; or

set the modified predModeIntra to (the original predModeIntra−67) when all of the following are true:
the variable nH is greater than the variable nW,
the original predModeIntra is less than or equal to 66, and
the original predModeIntra is greater than (the variable whRatio>1)?(60−2*the variable whRatio):60;
wherein the variable whRatio is set equal to Abs(Log 2(the variable nW/the variable nH)).
