METHOD AND SYSTEM OF MANUALLY SETTING CHANNELS
A method of manually setting a channel within a frequency range. The method comprises the following steps. A start frequency and a surf direction are set, and then surf channels. When a target channel is found or a pause instruction is received, surfing pauses. An auto naming function is executed to obtain a channel name of the target channel. A user determines whether to keep the channel name in a channel list. Surfing is repeated until the entire frequency range is searched or a stop instruction is received.
1 . A method of manually setting channels within a frequency range, wherein the frequency range is between a first frequency and a second frequency, the method comprising:
(A) providing a starting frequency and a surf direction, and searching for a target channel according to the surf direction, wherein the target channel is a channel with a signal comprising channel information;
(B) recording a current frequency as a target frequency when finding the target channel or receiving a pause searching instruction;
(C) executing an auto naming function to obtain a channel name of the target channel;
(D) determining whether to record the channel name and the target frequency in a channel list; and
(E) continuing to surf according to the surf direction, and returning to step (B).
2 . The method as claimed in claim 1 , wherein the surf direction in step (A) is surfing from the starting frequency toward to the first frequency, and when reaching to the first frequency, surfing from the second frequency toward the starting frequency.
3 . The method as claimed in claim 1 further comprising stopping searching for the target channel upon reaching the starting frequency.
4 . The method as claimed in claim 1 , wherein the surf direction in step (A) is a direction from the starting frequency toward the first frequency, and when reaching to the first frequency, surfing from the starting frequency toward the second frequency.
5 . The method as claimed in claim 4 further comprising stopping searching the target channel upon reaching the second frequency.
6 . The method as claimed in claim 1 , wherein the first and second frequencies are adjustable.
7 . The method as claimed in claim 1 , between step (C) and step (D), further comprising:
(C-1) displaying the channel name of the target channel.
8 . The method as claimed in claim 1 , wherein the target channel is a television channel.
9 . The method as claimed in claim 1 , wherein the channel information comprises a channel code and the auto naming function of the step (C) comprises:
obtaining the channel code from the channel information of the target channel; and
retrieving the channel name from a table, wherein the table comprises the channel code and the channel name corresponded to the channel code.
10 . The method as claimed in claim 1 further comprising stopping searching channel when receiving a stopping searching instruction during executing step (A) to step (E).
11 . A system for manually setting channels within a frequency range, wherein the frequency range is between a first frequency and a second frequency, and the system comprises:
a user interface receiving a pause searching instruction, a store instruction, and a surf direction;
a tuner searching for a target channel according to the surf direction from a starting frequency, and pausing searching when the target channel is found at a target frequency or the user interface receives the pause searching instruction, wherein the target channel is a channel with a signal comprising channel information;
a storage unit storing a channel list; and
a processing unit coupled to the tuner, the user interface and the storage unit, executing an auto naming function to obtain a channel name of the target channel, and when the user interface receives the store instruction, storing the target frequency and channel name of the target channel into the channel list.
12 . The system as claimed in claim 11 further comprising a display module displaying the channel name of the target channel obtained by the processing unit.
13 . The system as claimed in claim 11 , wherein the storage unit further comprises a look-up table, the look-up table comprises a channel code and the channel name corresponding to the channel code, and the system further comprises a teletext processing unit to obtain the channel code from the channel information; when the auto naming function is executed, the processing unit searches the look-up table in the storage unit by the channel code to obtain the channel name of the target channel.
14 . The system as claimed in claim 13 , wherein the channel code is a Country Network (CNI) code.
15 . The system as claimed in claim 11 , wherein the surf direction is surfing from the starting frequency toward the first frequency, and upon reaching the first frequency, surfing from the second frequency toward the starting frequency.
16 . The system as claimed in claim 15 , wherein the tuner stops searching the target channel when the tuner searches to the starting frequency.
17 . The system as claimed in claim 11 , wherein the surf direction is searching from the starting frequency toward the first frequency, and upon reaching the first frequency, searching form the starting frequency toward the second frequency.
18 . The system as claimed in claim 17 , wherein the tuner stops searching the target channel when the tuner searches to the second frequency.
19 . The system as claimed in claim 11 , wherein the user interface receives a pause searching instruction, and when the user interface receives the pause searching instruction, the tuner stops searching.
20 . The system as claimed in claim 11 , wherein the first frequency and the second frequency can be adjusted via the user interface.
