Please refer to both Figure 1 and Figure 2. 1 is a block diagram of a handheld electronic device 1 in accordance with an embodiment of the present invention. 2 is a top plan view of a handheld electronic device 1 in accordance with an embodiment of the present invention. The handheld electronic device 1 has a universal remote control mechanism. In various embodiments, it can be, for example, a smart phone, a tablet or other handheld electronic device. The handheld electronic device 1 includes a touch display unit 10, a storage unit 12, a wireless transmission unit 14, and a processing unit 16.

The touch display unit 10 is configured to receive the device information 11. In an embodiment, the device information 11 includes the device label and the type of the device. For example, the user can input, for example, but not limited to, a Sony television set or a Toshiba air conditioner to the touch display unit 10 as the device information 11. The touch display unit 10 will display the user interface 20 as shown in FIG. 2 according to the device information 11. User interface 20 includes a plurality of virtual function keys 22.

Taking a television as an example, the virtual function keys 22 may include, for example, but are not limited to, a power button, a volume adjustment button (such as volume + and volume in FIG. 2), and a channel adjustment button (such as channel + in FIG. 2). Channel-), menu button, mute button and number button, etc.

The storage unit 12 stores the device code difference table 120. Device code difference table 120 It is used to store the multiple device codes corresponding to the specific model devices. The processing unit 16 can test the electronic device 18, that is, the electronic device corresponding to the device information 11 input by the user, after the device code difference table 120 is retrieved from the storage unit 12 according to the device information 11. Among the device codes, which can be controlled by the electronic device 18 to be controlled. In the process of the test, after the processing unit 16 generates an instruction according to the device code difference table 120, the wireless transmission unit 14 is controlled to transmit an instruction to the electronic device 18 to be tested for testing. In an embodiment, the wireless transmission unit 14 can be, for example, but not limited to, an infrared transmission unit, such that a receiving module (not shown) corresponding to the electronic device 18 to be controlled receives the instruction.

Please refer to Figure 3. FIG. 3 is a schematic diagram of a device code difference table 120 according to an embodiment of the present invention.

In this embodiment, the device code difference table 120 includes a plurality of column device codes, which are numbered by 001, 002, 003, ..., 006, respectively. Each device code corresponds to a particular model of device. Each column of device code contains a plurality of instruction codes. For example, in the device code numbered 001, the command code of the power button is 10h, the command code of the channel up (channel +) button is 20h, and the command code of the channel down (channel-) button is 30h. analogy. It should be noted that the device code difference table 120 shown in this embodiment is only an example, and the number of device codes included in the device code and the number of command codes included in each device code can be adjusted according to actual conditions.

In this embodiment, the instruction codes in each device code are sorted by a hit rate. The term "hit rate" is used in this embodiment to correlate similarities in the instruction codes between the respective device codes. That is to say, the instruction code with a high hit rate is between the code of each device, and the instruction code repeats the most. In other words, the instruction code can The ordering is performed by the relative meaning of the hit rate, that is, the discrimination rate. That is to say, the lower the recognition rate, the higher the hit rate. For example, if an instruction code is repeated in multiple sets of device codes, it is more difficult for the instruction code to identify different device codes, and the recognition rate will be lower. However, since there are many device codes that conform to this instruction code, the hit rate is high. On the other hand, if an instruction code appears only in a group of device codes, the instruction code can easily distinguish the set of device codes from other device codes, and the recognition rate is high. However, since there is only one device code that conforms to this instruction code, the hit rate is low.

Taking the device code difference table 120 shown in FIG. 3 as an example, the power button has three device codes having the same command code 10h among the six device codes, so the power button has the highest hit rate. Similarly, the channel up (channel +) button, channel down (channel -) button, volume up (volume +) button, and volume down (volume -) hit rate are also highest. Therefore, these instruction codes will be prioritized, which in this embodiment is prioritized on the left side of the table. In an embodiment, between the columns of device codes, as shown in FIG. 3, several device codes with high similarity are preferentially classified into the same group.

Therefore, the processing unit 16 in FIG. 1 will perform the test flow in the sorting manner of the table after the device code difference table 120 is captured. Please refer to Figure 1 and Figure 4A to Figure 4C at the same time. 4A to 4C are plan views of the handheld electronic device 1 in the test flow, respectively, according to an embodiment of the present invention.

At the beginning of the test flow, the processing unit 16 will, in step (a), make the highest hit rate among the instruction codes of a particular device code in the device code discrimination table 120 as the first instruction code. Distinguish the table 120 with the device code in FIG. For example, the processing unit 16 may preferentially use the device code numbered 001 as the specific device code, and use the command code 10h of the power button as the first command code.

The processing unit 16 in step (b) will control the touch display unit 10 to receive an input 13 from one of the virtual function keys 22, wherein the specific virtual function key corresponds to the first instruction code. In this embodiment, since the first instruction code is the instruction code 10h of the power key, the specific virtual function key is a power key.

As shown in FIG. 4A, in an embodiment, the processing unit 16 may first generate a specific virtual function key (such as the power key in this embodiment) according to the first instruction code, that is, the instruction code 10h corresponding to the power key.

In an embodiment, if the wireless transmission unit 14 is a unidirectional transmission unit of the infrared transmission unit type, the processing unit 16 needs to determine whether the touch display unit 10 receives the confirmation input (not shown) of the user to determine Whether the electronic device 18 to be controlled has operated according to the function command 15. In one embodiment, the processing unit 16 can generate a virtual selection button for the user to select "Yes" or "No" to determine that the electronic device 18 to be controlled does not operate according to the function instruction 15 when receiving the "No" input. In another embodiment, when the processing unit 16 does not receive the confirmation input within a certain time, it is determined that the electronic device 18 to be controlled is not operated according to the function instruction 15 Work.

When the electronic device 18 to be controlled does not operate according to the function instruction 15, the processing unit will exclude the first device code in the specific device code and other device codes in step (e). In this embodiment, the power key command code is 10h, that is, the device code numbered 001 and the device code numbers 002 and 003 are excluded.

Processing unit 16 further causes one of the remaining device codes to be tested as a particular device code to repeat steps (a)-(d). For example, if the function command 15 generated according to the power key command code 10h fails to operate the electronic device 18 to be controlled, the processing unit 16 will exclude the device code of the number 001-003, and further use the device code numbered 004 as Specific device code and perform the tests of steps (a)-(d). If it still does not match, it will find the next suitable device code for testing.

When the processing unit 16 determines in step (d) that the electronic device 18 to be controlled operates according to the function instruction 15, the processing unit 16 further determines in step (f) whether the first instruction code is the last instruction code of the specific device code. Taking the embodiment as an example, if the function command 15 generated by the power key command code 10h can make the electronic device 18 to be controlled operate, the processing unit 16 will judge that it is not the last instruction code, but will be after the first instruction code. The second instruction code is used as the first instruction code, and steps (b)-(d) are repeated for testing. That is, the processing unit 16 can select the instruction code 20h of the channel up (channel +) key as the instruction code of the next test.

However, in an embodiment, the processing unit 16 can further determine whether the remaining instruction code has the same first instruction code in the specific device code (numbered 001) and other device codes (number 002 and 003) Repeat between. That is, the processing unit 16 can determine whether the other instruction codes are repeated between the device codes numbered 001, 002, and 003. In this embodiment, the channel up (channel +) button, the channel down (channel -) button, the volume up (volume +) button, and the volume down (volume -) button are all repeated, so the processing unit 16 can Directly determining these repeated instruction codes can cause the electronic device 18 to be controlled to operate according to the function instructions 15 it generates, and will not be tested. The processing unit 16 may perform one of the non-repeating ones of the instruction code, such as the instruction code 60h of the mute key, as the first instruction code to repeat the steps (b)-(d) to speed up the test procedure.

In an embodiment, as shown in FIG. 4B, the processing unit 16 can control the touch display unit 10 to display the virtual function key that passes the test with a second prompt information. In this embodiment, the second prompt information is displayed as a color change to prompt the user that the virtual function key has passed the test.

In an embodiment, when a plurality of instruction codes in a specific device code pass the test but encounter the next instruction code failing the test, the processing unit 16 may select the highest similarity to the specific device code from the remaining device codes. The test is performed, and the remaining instruction code can be directly tested by directly skipping the instruction code that is repeated and passed the test.

As shown in FIG. 4C, when the processing unit 16 determines in step (d) that the electronic device 18 to be controlled operates according to the function instruction 15, and determines the last instruction code in the code of the first instruction code device in step (f), The processing unit 16 will end the test flow in step (g) and control the electronic device 18 to be controlled with this specific device code. In this embodiment, when the processing unit 16 tests the up key instruction code 90h of the device code numbered 001 and judges that it has passed the test, the test flow will be ended, and the control device will be controlled by the specific device code. Device 18.

Therefore, the device code distinguishing table sorted by the command code hit ratio, the handheld electronic device of the present invention can quickly find the device code and perform testing to efficiently and quickly find the device code corresponding to the electronic device to be controlled and perform remote control.

In an embodiment, the processing unit 16 can further record the correspondence between the specific device code and the electronic device 18 to be controlled by using the environmental information of the electronic device 18 to be controlled. For example, the environmental information may be the wireless access point signal strength, vertical height, or corresponding orientation around the electronic device 18 to be controlled, and the processing unit 16 may be implemented by a wireless transmission module, a level, an electronic compass, or the like. The built module obtains relevant environmental information and records it.
