Therefore, dedicated remote controls are required in order to transmit appropriate remote control signals with corresponding operating frequency range while using different electronic products. Thus, making it very inconvenient for users, as more and more electronic products are being equipped with wireless remote control functions because users need more remote controllers in response to various electronic products with different operating frequencies.
Therefore, integrating various remote controls to improve the convenience of user has become an important issue among manufacturers.

BRIEF DESCRIPTION OF THE DRAWINGS
The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
FIG. 1 shows a diagram of an electronic apparatus with remote control functions according to present invention.



DETAILED DESCRIPTION OF THE INVENTION
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
Referring to FIG. 1, a diagram of an electronic apparatus with remote control functions is shown according to present invention. As shown in FIG. 1, the electronic apparatus 10 with remote control functions comprises an operating module 12, a control module 14 and a transmitting module 16. The operating module 12 is used to generate at least an operating signal S0. The control module 14 is coupled to the operating module 12 and generates at least a first control signal SC1 and at least a second control signal SC2 according to the operating signal S0. The transmitting module 16 is coupled to the control module 14 and transmits the first control signal SC1 and the second control signal SC2, wherein the first control signal SC1 is within a first frequency range, and the second control signal SC2 is within a second frequency range. The electronic apparatus 10 is a portable electronic apparatus. In one embodiment, the portable electronic apparatus is a cell phone.
In addition, the operating module 12 further comprises an operating interface 121 for user operation to generate the operating signal S0. In one embodiment, the operating interface 121 represents a plurality of keys of a cell phone.
The control module 14 comprises a memory unit 141 coupled to the operating module 12. The memory unit 141 stores a plurality of data sets. The control module 14 generates the first control signal SC1 and the second control signal SC2 according to the operating signal S0 and the data sets.
The data sets comprise a plurality of operating signals S0 individually corresponding to the first control signal SC1 or second control signal SC2 for each operating signal S0. In one embodiment, the data sets are stored in a table, and the control module 14 locates the corresponding first control signal SC1 or second control signal SC2 in a table-lookup manner based on the operating signal S0.
The control module 14 further comprises a determination unit 143 for determining whether the memory unit 141 has the corresponding first control signal SC1 or second control signal SC2 when receiving at least an operating signal S0. If the determination unit 143 determines that the data sets stored in the memory unit 141 have the corresponding first control signal SC1 or second control signal SC2 for the operating signal S0, the determination unit 143 controls the control module 14 to transmit the first control signal SC1 or second control signal SC2 to the transmitting module 16.
If the determination unit 143 determines that the data sets stored in the memory unit 141 do not have the first control signal SC1 or second control signal SC2 for the operating signal S0, the determination unit 143 generates a setting signal SS. Furthermore, the electronic apparatus 10 further comprises a receiving module 18 coupled to the control module 14. The receiving module 18 is used to receive an external signal SW and transmit the external signal SW to the memory unit 141 when setting signal SS is provided from the control module 14. The memory unit 141 further stores the external signal SW and the operating signal S0 after receiving the external signal SW.
In this embodiment, the determination unit 143 is used to determine whether the memory unit 141 has the operating signal S0 issued from the operating module 12 and the corresponding first control signal SC1 or second control signal SC2. If so, the procedure continues. If not, the external signal SW is received through the receiving module 18, and the new data set is added to the memory unit 141 for future use. In this manner, the remote control signals of desired electronic products can be newly added to the electronic apparatus 10 according to the need of users, thus providing for improved convenience.
Furthermore, the receiving module 18 further receives at least a communication signal ST and transmits the communication signal ST to the control module 14, and the control module 14 generates at least a third control signal SC3 according to the communication signal ST. The frequency of the third control signal SC3 is approximately the same as the second control signal SC2. In this embodiment, because the frequency of the third control signal SC3 is approximately the same as the second control signal SC2, and the first control signal SC1 and the second control signal SC2 are within different frequency ranges, the first control signal SC1 and the third control signal SC3 can be transmitted at the same time by the transmitting module 16. In one embodiment, the first control signal SC1 is the wireless signal transmitted from conventional remote controls, which are typically infrared signals within a lower frequency range. The second control signal SC2 includes a dial signal from conventional cell phones, and the third control signal SC3 includes the communication signal during a call. Meanwhile, the second control signal SC2 and the third control signal SC3 have an analogous frequency range higher than that of the first control signal SC1.
Because the first control signal SC1 and the third control signal SC3 have different operating frequency ranges, the electronic apparatus 10 with remote control functions in the present invention both have a remote control function and a cell phone function at the same time, and those signals SC1, SC2 and SC3 can be transmitted through transmitting module 16. Furthermore, because the first control signal SC1, the second control signal SC2 and the third control signal SC3 are operated within two different frequency ranges, user can also use the remote control function while talking on the phone by the electronic apparatus 10 of the present invention.
As described above, the electronic apparatus with remote control functions of the present invention integrates the conventional remote controller into a cell phone and generates the different frequency first control signal (the wireless signal of remote controller), second control signal (the dial signal of cell phone) and third control signal (the communication signal during a call) through the control module. Moreover, the remote control signal and signals of the cell phone that are within different frequency ranges can be transmitted simultaneously by the transmitting module. In this manner, the remote control and cell phone can be combined together to provide improved convenience for users, thus solving the problems in the prior art.
While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
