[0018] Figure 3 A schematic diagram illustrating the OSD menu voice control process according to an embodiment of the present invention is shown. Detailed Implementation

[0019] To provide a further understanding of the purpose, structure, features, and functions of the present invention, detailed descriptions are provided below with reference to specific embodiments.

[0020] Please refer to Figure 1 The diagram illustrates the architecture of a display system 100 according to an embodiment of the present invention. The display system 100 includes a main control device 110, a display 120, and an audio playback module 118 or an audio playback module 126. The audio playback module 118 may be externally connected to or built into the main control device 110, and the audio playback module 126 may be externally connected to or built into the display 120. The audio playback modules 118 and 126 are, for example, sound cards connected to a speaker for playing voice messages or prompts.

[0021] The main control device 110 is, for example, a computer or mobile communication device, and includes a processor 112, at least an application program 114, and a voice packet processing module 116. The main control device 110 is connected to a display 120 via a transmission cable 111, such as an audio / video signal cable, like a VGA cable, D-SUB cable, HDMI cable, and / or an audio source cable. The main control device 110 can connect to a remote database 130 via wireless communication or a local area network to download voice packets 132. The downloaded voice packets 132 can be stored in the main control device 110 for future use.

[0022] The remote database 130 contains various voice packets 132. The application program 114 of the main control device 110 can download the voice packet according to the model of the display 120 and store it in the main control device 110. For example, it can download the voice packet corresponding to the internal OSD menu 141 of the display 120 of brand A, or the voice packet corresponding to the internal OSD menu 141 of the display 120 of brand B. Since the OSD menu 141 used by different models of display 120 may be different, the remote database 130 pre-sets different voice packets 32 for different models of display 120 for download.

[0023] In another embodiment, the application program 114 of the main control device 110 can download the voice packet 132 according to the language setting of the main control device 110. For example, if the main control device 110 has a Chinese language setting that supports Chinese, then the application program 114 can download the Chinese voice packet according to the language setting of the main control device 110; if the main control device 110 has an English language setting that supports English, then the application program 114 can download the English voice packet according to the language setting of the main control device 110, and so on. Since the language settings of the main control device 110 may vary, the remote database 130 pre-sets different language voice packets 132 for different language settings of the main control device 110 for download.

[0024] Please refer to Figure 1 The display 120 includes a display panel 121, a storage unit 122, and a control unit 124. The storage unit 122 stores an OSD (On-Screen Display) mapping table 140, which includes a corresponding first menu string 142 and a first voice index 144. For example... Figure 2As shown, the first menu string 142 is one of the strings in the OSD menu 141, such as the mode 1 string "Standard", mode 2 string "Multimedia", mode 3 string "Movie", mode 4 string "Game", and voice mode string "Friendly", etc. When the user selects the voice mode, the selected string in the OSD menu 141 on the display 120 can be played by voice. Each menu string has a corresponding voice index; for example, the string "Standard" corresponds to voice index "1", the string "Multimedia" corresponds to voice index "2", the string "Movie" corresponds to voice index "3", the string "Game" corresponds to voice index "4", and the string "Friendly" corresponds to voice index "5".

[0025] The corresponding voice packet can be retrieved through the voice index. For example... Figure 2 As shown, the first voice packet is one of the voice packets 132 stored in the remote database 130, such as packet one "Standard", packet two "Multimedia", packet three "Movie", packet four "Game", and packet five "Friendly". Voice index "1" is associated with packet one "Standard", voice index "2" is associated with packet two "Multimedia", voice index "3" is associated with packet three "Movie", voice index "4" is associated with packet four "Game", and voice index "5" is associated with packet five "Friendly". If each mode of the OSD menu 141 has a lower-level mode, then the menu string in the corresponding lower-level mode has a lower-level voice index and a corresponding lower-level voice packet, and so on, which will not be elaborated here.

[0026] Please refer to Figure 1 and Figure 2When a user presses the menu button on the display 120 and selects the voice menu function, the control unit 124 receives the first OSD command 146 from the user, and retrieves the first menu string 142 (e.g., the string "Standard") and the first voice index 144 (e.g., the voice index "1") from the storage unit 122 according to the first OSD command 146, and transmits them to the main control device 110. At this time, the application program 114 can retrieve a first voice packet 132 (e.g., packet one "Standard") corresponding to the first menu string 142 (e.g., the string "Standard") according to the first voice index 144 (e.g., the voice index "1"), and the voice packet processing module 116 opens the first voice packet 132 (e.g., packet one "Standard") and sends it back to the audio playback module 118 or the audio playback module 126. Audio playback module 118 or audio playback module 126 is used to play an audio file corresponding to the first menu string 142 (e.g., the string "Standard").

[0027] Please refer to Figures 1 to 3 ,in Figure 3 A schematic diagram illustrating the voice control flow of an OSD menu 141 according to an embodiment of the present invention is shown. This OSD menu 141 voice control flow is used for... Figure 1 In the display system 100, firstly, in step S210, the main control device 110 is connected to the display 120, which has an OSD mapping table 140, such as... Figure 2 As shown. In step S220, a first OSD command 146 is input, and a first menu string 142 and a first voice index 144 are obtained from the display 120 according to the first OSD command 146, and transmitted to the main control device 110. In step S230, the main control device 110 obtains a first voice packet 132 corresponding to the first menu string 142 according to the first voice index 144.

[0028] like Figure 1As shown, the main control device 110 can connect to the remote database 130 via wireless communication or a local area network to download the first voice packet 132. Alternatively, in another embodiment, the main control device 110 can directly translate the first menu string 142 into the first voice packet 132 using an external translation program. The external translation program is, for example, online translation software or a downloaded translation program (i.e., the first program). Therefore, in step S240, the main control device 110 can execute the first program to perform source code translation and obtain the first voice packet 132 corresponding to the first menu string 142 based on the source code translation. Furthermore, in another embodiment, the main control device 110 can also translate the prompt messages provided by the display 120. For example, when the transmission line 111 of the display 120 is not connected properly, the display 120 is in sleep mode, or the OSD menu 141 displays an error message, the user can be notified via voice prompts. Therefore, in step S250, when the display 120 shows the OSD prompt message, the main control device 110 translates the OSD prompt message to obtain the first voice packet 132. The translation program can be, for example, online translation software or a downloaded translation program, and the present invention does not limit it to this.

[0029] In step S260, the voice packet processing module 116 of the main control device 110 can open the first voice packet 132 to play the voice file corresponding to the first menu string 142. Therefore, the user can complete the voice control process of the OSD menu 141 through the above steps S210 to S260.

[0030] The display system, monitor, and method with voice prompt function described in the above embodiments of the present invention first install a customized application on the main control device. The application automatically connects to a remote database, then downloads the voice packets of the OSD menus supported by the monitor and stores them in the main control device. When the user selects an OSD menu on the monitor or when any OSD prompt message appears on the screen, the monitor notifies the main control device via the Data Display Channel (DDC) and command interface. After receiving the instruction transmitted by the monitor, the main control device selects the address of the voice packet to be downloaded and establishes a connection, transmitting the voice packet of the currently selected menu string back to the main control device via a transmission line. Finally, after receiving the audio source signal, the audio playback module plays the voice file corresponding to the first menu string through the speaker.

[0031] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
