Detailed ways

With the development of technology, today's TV sets can not only receive video programs input by antenna or cable, but also combine with Internet communication to extract rich information and digital content on the Internet. In other words, TV sets can directly connect to the broadband Internet and play digital content without a personal computer or a digital set-top box. In this way, the present invention utilizes a television set that can be connected to the broadband Internet to realize internet telephony, and connects it with a smart mobile phone to solve the problem of a voice microphone receiving device. To put it simply, one of the difficulties lies in how to set up the microphone if the Internet telephony is to be realized through the existing TV set that can be connected to the broadband Internet. That is to say, if a microphone is added to the casing of the TV, the microphone will not receive sound well because the average user usually keeps a distance of about 3 meters from the TV when using the TV. Conversely, if an external microphone is connected through a signal extension cable, etc., the convenience will be reduced. Therefore, in order to improve the problem of microphone setting, the present invention utilizes the network connection function of the smart phone and its high-efficiency microphone sound collection effect, and integrates it with a TV set that can access the Internet, thereby realizing a home Internet phone.

Please refer to FIG. 1A and FIG. 1B , FIG. 1A is a schematic diagram of a telephone system 10 according to an embodiment of the present invention, and FIG. 1B is a functional block diagram of the telephone system 10 . As shown in FIG. 1A and FIG. 1B , the phone system 10 includes a television 12 and a smart phone 14 . The television set 12 includes a screen 120 , a speaker 122 , a wireless transceiver module 124 , a lens 128 , an Internet phone module 130 and a signal processing module 132 . The smart phone 14 includes a screen 140 , a microphone 142 , a speaker 144 , a lens 146 , a keyboard 148 , a wireless transceiver module 150 and a control unit 152 . In the TV set 12, the signal processing module 132 can receive an external audio-visual signal IMG_EXT, such as a TV broadcast signal, an audio-visual player signal, etc., and output its multimedia content through the screen 120 and the speaker 122; and the Internet phone module 130 can be connected to To the Internet NET, combined with the operation of the smart phone 14, to realize the function of Internet phone. In this way, a user USR1 can perform an Internet video phone connection with a destination communication terminal, so that both parties can observe each other's images IMG_USR1 and IMG_USR2. In short, the screen 120, the speaker 122 and the signal processing module 132 represent the necessary components of a conventional TV set, and the operating principles thereof are well known to those skilled in the art. As for how the phone system 10 performs the operation of the Internet phone, the operation and related output of each component in different modes will be described below in conjunction with different icons.

First, as shown in FIG. 2A , the telephone system 10 receives the voice of the user USR1 through the microphone 142 of the smart phone 14 , and plays the voice of the destination communication terminal through the speaker 122 of the TV 12 . In other words, neither the screen 120 of the TV 12 nor the screen 140 of the smart phone 14 displays any picture (of course, other pictures can also be displayed, which will be described in detail later), and the wireless signal output from the smart phone 14 to the TV 12 Only the voice received by the microphone 142 . In detail, when operating in this mode, the voice received by the microphone 142 is first transmitted to the control unit 152 , and then transmitted to the wireless transceiver module 124 through the wireless transceiver module 150 through wireless communication. After the wireless transceiver module 124 receives the voice signal of the user USR1, the voice signal of the user USR1 is transmitted by the network phone module 130 to the destination communication terminal through the Internet NET. In contrast, the VoIP module 130 receives the voice signal from the destination communication terminal through the Internet NET, and drives the speaker 122 to emit a corresponding sound through the signal processing module 132 .

Therefore, the example of FIG. 2A can be regarded as the most basic VoIP function of the telephone system 10, that is, only the VoIP communication function, without the video telephony function. Meanwhile, in this example, neither the lens 128 of the television 12 nor the lens 146 of the smart phone 14 captures an image. In other words, this example can be further derived and applied to televisions and smart phones without lenses. That is to say, the main purpose of the present invention is to capture the voice signal of the user USR1 through the microphone 142 of the smart phone 14, and then realize the function of Internet phone, so even if the TV 12 and the smart phone 14 are not equipped with the lens 128 and 146 or the lenses 128 and 146 cannot work, or the communication content of the destination communication end only has voice components, which will not affect the realization of the concept of the present invention. In this case, the mode shown in FIG. 2A can be set as the power saving mode, that is, the Internet phone function can be realized through the TV 12 and the smart phone 14 with the lowest power consumption. In addition, in this mode, TV programs or preset background icons, photos, etc. can also be played through the screen 120, such as displaying a caller's photo.

Continuing the example of FIG. 2A, if the screen 120 of the TV set 12 is turned on, and the network phone module 130 has received the video signal of the destination communication terminal (that is, the communication content of the destination communication terminal has video and voice components), then the video can be displayed on the screen 120 IMG_USR2, as shown in FIG. 2B ; or transmit the image signal to the smart phone 14 and display it on the screen 140 at the same time, as shown in FIG. 2C . That is to say, when operating in the mode shown in FIG. 2B , in addition to transmitting voice signals as shown in FIG. 2A , the TV 12 and the smart phone 14 will simultaneously receive video signals from the destination communication terminal via the Internet NET, and process them through signal processing. The module 132 drives the screen 120 to display the corresponding image IMG_USR2. Or, further, the Internet phone module 130 can transmit the image signal of the destination communication terminal to the wireless transceiver module 150 through the wireless transceiver module 124, so that the control unit 152 drives the screen 140 to display the image IMG_USR2 at the same time, as shown in FIG. 2C .

2B and 2C show that the telephone system 10 receives the image signal of the destination communication terminal, so the image IMG_USR2 can be displayed on the screen 120 or displayed on the screen 140 synchronously. This mode can be the manifestation of the following three application situations: 1. The TV 12 and the smart phone 14 are not equipped with the cameras 128 and 146; 2. The cameras 128 and 146 are not in operation; 3. The cameras 128 and 146 are in normal operation , but the image IMG_USR1 of the user USR1 is not displayed on the screen 120 or 140 .

If the lenses 128 and 146 operate normally, the image IMG_USR1 of the user USR1 can also be displayed on the screen 120 or 140 , and the display method is not limited. For example, in FIG. 2D , both screens 120 and 140 display images IMG_USR1 and IMG_USR2 at the same time; in FIG. 2E , screen 120 displays images IMG_USR1 and IMG_USR2 at the same time, but screen 140 only displays images IMG_USR2 . By analogy, the screen 120 can display images IMG_USR1 and IMG_USR2 simultaneously, but the screen 140 only displays the image IMG_USR1; or, the screen 120 displays the image IMG_USR2, and the screen 140 displays the image IMG_USR1 . . . and so on.

On the other hand, in addition to outputting the voice of the destination communication terminal through the loudspeaker 122, there are also other multiple output methods. For example, the VoIP module 130 can transmit the voice signal of the destination communication terminal to the smart phone 14 , and the control unit 152 drives the speaker 144 to play the voice of the destination communication terminal. At the same time, the aforementioned various implementations may be combined with each other depending on design requirements, and are not limited thereto.

It should be noted that, regardless of any one of the above-mentioned examples for performing the VoIP, the VoIP module 130 captures the voice signal of the user USR1 through the smart phone 14 through wireless communication. In this case, there is no need for an additional microphone on the TV 12, and the microphone 142 of the smart phone 14 usually has an excellent sound collection effect, so the user USR1 can place the smart phone 14 on the table and directly face the TV 12Make a video call. Of course, the user USR1 can also pick up the smart phone 14 and make an Internet call as if talking on the phone (that is, only the voice of the destination communication terminal is output from the smart phone 14 ).

In addition, in order to avoid the impact of video telephony on the playback of TV programs or multimedia content, the signal processing module 132 can also have multiple display modes, such as the picture on picture display mode shown in Figure 3A and the picture-in-picture ( Picture in Picture) display mode, etc. FIG. 3A and FIG. 3B are embodiments of the present invention, and those skilled in the art may make various changes or modifications accordingly, without being limited thereto. For example, the proportions of TV programs and video phone screens can be changed according to different needs, and the display mode such as main and sub-picture (Picture and Picture) can be realized; the video phone content can also include only images IMG_USR1 and IMG_USR2 one of them. In addition, an indication mechanism can also be added, that is, when a call comes in while watching TV, a small window can be displayed on the screen 120 or (and) the screen 140 to remind the incoming call. When the user accepts an incoming call, the system automatically mutes the sound part of the external video signal IMG_EXT, and switches to the sound source of the destination communication terminal; when the call is over, it automatically switches to output the sound of the external video signal IMG_EXT. Of course, when the TV is used for video calling, the picture mode on the screen 120 or (and) the screen 140 can also be switched in the same operation manner.

Furthermore, when the user USR1 needs to dial a phone number, it can be realized through the keyboard 148 of the smart phone 14 . In this case, the signal transmitted from the wireless transceiver module 150 to the wireless transceiver module 124 is not limited to the voice or video content of the user USR1, but also includes instructions corresponding to the phone number.

Generally, users usually keep a distance of about 3 meters from the TV when using the TV, which causes poor sound reception effect of the microphone. In order to improve the microphone setting problem, the present invention utilizes the network connection function of the smart phone and its high-efficiency microphone sound collection effect, and integrates it with an Internet-connected TV, so that the user can place the smart phone on the table and face directly Make video calls to the TV, or pick up your smartphone and make Internet calls like talking on the phone. Therefore, the present invention can effectively solve the problem of the voice microphone receiving device, and further enhance the user's willingness to use the Internet phone.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
