Method and system for scanning television systems using a first quick scan and a second slower scan
A method of scanning television channels at initial setup. The method includes at a first power mode, automatically scanning for channels using a first scanning setup procedure during which the television is unusable by a user. The first power mode is when the television is at a full power mode. The detected channels are automatically provided for use by the television upon completion of the first scanning setup procedure. The method further includes automatically scanning for channels using a second scanning setup procedure at a second power mode following the first power mode. The second power mode is at a lower power mode than the first power mode, and the second scanning setup procedure is more time consuming in comparison to the first scanning setup procedure. Additional channels not detected during the initial setup by the first scanning setup procedure are automatically detected at the second power mode.
1. A computer readable medium comprising instructions that when executed implement a method for scanning television channels at initial setup, said method comprising:
at a first mode, automatically scanning for channels using a first scanning setup procedure during which said television is unusable by a user,
upon completion of said first scanning setup procedure, automatically providing detected channels for use by said television; and
at a second mode, automatically scanning for channels using a second scanning setup procedure, wherein responsive to a channel being found in a scanning setup procedure for a first carrier standard and a first modulation standard, the first carrier standard and the first modulation standard are subsequently used during the scanning setup procedure to find remaining channels, and responsive to a determination that a channel is not found in the scanning setup procedure within a time period, at least a second carrier standard and/or at least a second modulation standard is subsequently used during the scanning setup procedure.
2. The computer readable medium as described in claim 1 , wherein said automatically scanning for channels using said second scanning setup procedure further comprises:
automatically detecting additional channels not detected during said initial setup by said first scanning setup procedure.
3. The computer readable medium as described in claim 2 , wherein said method further comprises:
in response to said detecting said additional channels, automatically providing said additional channels for use by said television when said television is at said first mode.
4. The computer readable medium as described in claim 2 , wherein said method further comprises:
in response to said detecting said additional channels, automatically prompting said user that said additional channels are detected, wherein said prompting occurs at said first mode.
5. The computer readable medium as described in claim 1 , wherein said method further comprises:
subsequent to said automatically scanning for channels using said second scanning setup procedure, automatically and periodically scanning for channels using said second scanning setup procedure at standby power mode.
6. The computer readable medium as described in claim 1 , wherein said second scanning setup procedure has a longer time out parameter for finding a channel in comparison to said first scanning setup procedure.
7. The computer readable medium as described in claim 1 , wherein said first scanning setup procedure is limited to using a carrier and a modulation used to find a first detected channel when detecting remaining channels.
