Claim Text:
1. A television screen control apparatus comprising: a broadcasting contents data processing unit configured to receive new broadcasting contents when a channel is changed in response to a first channel changing input signal, to provide currently received broadcasting contents to a first plane, and to provide the new broadcasting contents to the first plane in response to the first channel changing input signal; a channel changing advertisement processing unit configured to provide a channel zapping advertisement to a second plane visually positioned behind the first plane, wherein a size of the second plane is substantially the same as a size of the first plane, the second plane being hidden by the first plane when currently received broadcasting contents or new broadcasting contents are provided to the first plane, the second plane being displayed only after the first channel changing input signal and before the new broadcasting contents are provided; and a screen mixing unit configured to combine first plane image information and second plane image information, each received from the broadcasting contents data processing unit, with each other to provide a mixed output screen, wherein the channel changing advertisement processing unit includes: a receiver configured to receive the channel changing input signal and channel zapping advertisement information; a channel zapping advertisement controller configured to generate a channel zapping advertisement matching table based on channel zapping advertisement image data and channel zapping advertisement providing data that are included in the channel zapping advertisement information; and a channel zapping advertisement database configured to store the channel zapping advertisement information and the channel zapping advertisement matching table therein, and wherein the channel zapping advertisement controller determines whether to change the channel zapping advertisement by comparing a broadcasting channel provided to the mixed output screen to the channel zapping advertisement matching table when a second channel changing input signal is not received for a predetermined time after the first channel changing input signal is received.
