Fast adaptive channel converting method and apparatus, and computer readable recording medium for executing the fast adaptive channel converting method

A fast adaptive channel changing method comprising:

• generating adjacent channel data by pre-signal processing an adjacent channel signal of a reference channel;
• receiving a channel change request from a user;
• searching for channel data corresponding to a changed channel in the adjacent channel data;
• and
• reproducing the searched changed channel data,
• wherein the changed channel and the reference channel are preferred channels having a high audience frequency, and
• wherein the fast adaptive channel changing method is performed based on the preferred channels.

A non-transitory computer readable recording medium having recorded thereon a program to execute a fast adaptive channel changing method comprising:

• generating adjacent channel data by pre-signal processing an adjacent channel signal of a reference channel;
• receiving a channel change request from a user;
• searching for channel data corresponding to the changed channel corresponding to the channel change request in the adjacent channel data;
• and
• reproducing the searched changed channel data,
• wherein the changed channel and the reference channel are preferred channels having a high audience frequency, and
• wherein the fast adaptive channel changing method is performed based on the preferred channels.

A digital television system, comprising:

• a display unit;
• a signal processing unit to decode channel signals into channel data displayed by the display unit;
• and
• a fast adaptive channel changing apparatus to control the signal processing unit to perform pre-signal processing on adjacent channel signals corresponding to adjacent channels of a reference channel using idle resources of the signal processing unit,
• wherein the adjacent channel and the reference channel are preferred channels having a high audience frequency, and
• wherein the fast adaptive channel changing is performed based on the preferred channels.
