Description of the Invention: [Technical Field] [0001] The present invention relates to a method for sharing audio and video materials, and more particularly to transmitting a screen and sound of an electronic device to other electronic devices. And the audio-visual sharing method and the application used by the other electronic devices. [Prior Art] [0002] Since the invention of the computer, it has been rapidly spread to the general public's life because of its convenience and powerful processing capabilities. Whether it is trivial chores in life or work, it can be processed by computer today. [0003] For the general public, the most common use of computers for recreation, such as the Internet, playing games and watching movies, and so on. Therefore, practitioners in the related art have developed a wide variety of technologies for the entertainment functions of computers. [0004] Taking video viewing as an example, most users are still accustomed to watching in a living room through a television with a large screen size. However, although it is convenient to play a movie on a computer, the computer is usually placed in a room, and the screen size of the computer is usually not as large as that of the TV, and the resolution is slightly inferior. Therefore, many wired and wireless video transmission methods have been proposed, which can transmit video and audio information such as screens and sounds of a computer to a television for playing on a larger screen size. [0005] However, even if the above-mentioned audio-visual material is transmitted to the television for playback, the user still needs to manipulate the computer to change the state of the audio-visual material (for example, selecting a file, fast-forwarding, and changing the size, etc.). As a result, the user can only use 100108922 Form No. A0101 Page 4 / Total 23 Page 1002015101-0 201240467 = Over the wireless _, mouse "« Side device to the computer remote remote [0006] Stone non-hanging is not suitable for users In the living room, users can't lie on the sofa as they please, or use computer peripherals such as keyboard and mouse in other two lazy postures. And, or the disk and the mouse are mainly connected to the computer through the B, PS/2 transmission 或 or through the wireless transmission of Bluetooth, infrared or radio (such as 2 bird radio). If the user's location is too far away from the computer, exceeds the length of the transmission line, or exceeds the wireless transmission distance such as Bluetooth, infrared or radio, the computer cannot be manipulated, which is quite inconvenient for the user. SUMMARY OF THE INVENTION [0007] The main purpose of the present invention is to provide a remote video and audio sharing method and an application thereof, which can capture the electronic device of the transmitting end (4), the surface of the screen and the sound [0008] And the different requirements of the control, the encoding action of different parameters, and respectively transmitted to the electronic device of the playing end and the electronic device of the control end, so that the user can easily view through the electronic device of the playing end, and is controlled by the electronic device of the control end. In order to achieve the above object, the present invention mainly captures the screen and sound of the screen from the electronic device of the transmitting end, and passes through the first encoding and the second encoding respectively, and then transmits the signal to a playback terminal electronic device and a control terminal electronic device for playing. After the playback electronic device receives the data and decodes it, the received data can be played smoothly. After the control terminal electronic device receives the data and decodes it, it can achieve the synchronous play effect with the transmitting end electronic device. Moreover, the control command can be generated by controlling the fine electronic device to be transmitted back to the transmitting end electronic device 100108922 Form No. A0101 Page 5 of 23 1002015101-0 201240467 ‘To control the operation of the transmitting end electronic device. And 'when the control command is generated', the transmitting terminal electronic device dynamically adjusts the parameters of the first code and the second code. In this way, in addition to satisfying the needs of the user for viewing and manipulation, the electronic device can be optimized. The encoding/decoding cost of the playback end electronic device and the control terminal electronic device. [0010] The present invention has the effect of comparing the prior art to that the transmitting end electronic device (for example, a computer) can capture the screen image and sound of the screen, and can perform high resolution on the playing end electronic device for viewing. Degree and high frame rate encoding, and retain a large buffer when transmitting. In this way, after receiving and decoding the data, the playback electronic device can perform relatively smooth and high-resolution playback, which is easy for the user to watch. Moreover, the transmitting end electronics can also encode low resolution and low frame rate for the control terminal electronics used for manipulation and retain a small buffer during transmission. Therefore, after receiving and decoding the data, the control terminal electronic device can play the screen and sound of the transmitting electronic device at a synchronous speed. Therefore, the user can easily control the transmitting electronic device :: . . . . . by the control terminal: sub-device. When a traditional user uses a remote video streaming application, if the electronic device at the receiving end is to be able to play the south image smoothly and smoothly, it needs to use a high bitrate encoding and provide a large buffer during transmission. Area. If you want the electronic device at the receiving end to be easy to manipulate, you need to use low bit rate (l〇w bitrate) encoding, and do not use buffering, so that users can see what they see is what they get through low latency. It is easy to control. However, the technical means required for the above two different purposes are mutually exclusive, and the prior art cannot reach 100108922.

The transmitting end device 1 is mainly ventilated by a computer, and is connected to a hard device (picture) such as an external keyboard and a mouse to control the internal operation. The player device 2 is mainly a player having a /screen size, such as a television or a projector. Further, if the j terminal device 2 is a smart TV (Smart TV), the playback device 2 can be mounted and directly executed. ‘'Right as shown in the second figure, when the playback device 2 is a playback S/* without a computing function, such as a conventional television or a projector, the playback device 2 must be externally connected to an expansion connection device 4. The expansion connection device 4 is internally installed and executed with the response mode 2 QH, the expansion connection m, the signal such as the high-definition multimedia interface (High j) eHnju〇n Mui-tlmedla Interface, HDMI) or AV terminal The line is electrically connected to the play end device 2. Therefore, the expansion connection device 4 receives the data transmitted by the transmission device 1, and after decoding, transmits the decoded screen image and sound to the playback device 2.2 for playback. The console device 3 is mainly a handheld electronic device such as a smart phone and a tablet f. The control device 3 has a touch screen 31, and as the case may be, the control device 3 may also be provided with a physical button 32. The screen size of the player device 2 is greater than the control terminal. The screen size of the touch screen 31 on the device 3. Therefore, both the playback device 2 and the console device 3 can receive and play the screen and sound of the transmission device 1, and the playback device 2 has a large screen size capable of higher resolution (higher Resolution) to play smoothly; and the console device 3 has a small touch form number A0101 page 9 / 23 pages 1002015101-0 201240467 type screen, playing with lower resolution and lower delay time Therefore, the synchronization effect can be achieved with the transmitting device 1 , so that the user can directly control the transmitting device 1 directly through the touch screen 31 or the physical button 32 . More specifically, both the playback device 2 and the console device 3 can play the screen and sound of the transmission device 1, but the achieved goals are not the same, so the received data is encoded differently. . [0022] Please refer to the fourth figure, which is a flow chart of a preferred embodiment of the present invention. First, the transmitting device 1 captures its own screen image and sound through the application 10 (step S40). Then, the transmitting end device 1 transmits a first encoding to the playing terminal device 2 through an encoder (not shown) (step S42), and then transmits the encoded data to the playing terminal device 2. Decoding and playing (step S44). Then, the transmitting end device 1 transmits the second encoding to the control terminal device 3 through the encoder (step S46), and then transmits the encoded data to the control terminal device 3 for decoding and playing ( Step S48). The step S44 is followed by the step S42, and the step S48 is followed by the step S46. However, the step S42 and the step S46 do not have an execution order relationship, which may be determined according to the actual situation. In steps S46 and S48, the steps S42 and S44 are performed, which are not limited. [0023] It is worth mentioning that the coding parameters used in the first coding and the second coding are not the same. The encoding parameters of the first encoding are mainly set for the playback device 2 for viewing, have a higher resolution, and a higher frame rate, for example, 30 frames per second (30 fps). Moreover, when transmitting data, the player device 2 retains a large buffer at the same time. 100108922 Table number A01G1 Page 10 of 23 100201510 Bu 0 201240467 (buffer). Therefore, a large buffer is used to overcome the situation in which the image is stopped, broken, or the video is not synchronized due to wireless interference under the condition of high quality "Η duality" and high bit rate (high bitrate^ wireless transmission). The playback device 2 generally has sufficient decoding processing capability, so that after the playback device 2 receives the data, the high bit rate data can be normally decoded, and the smooth (sm〇〇th) and high resolution playback can be performed. [0024] Ο G [0025] The decoding processing capability of the console device 3 is generally weaker than that of the player device 2, and the coded teaching of the second code is mainly for manipulation The console device 3 is set to have a lower resolution and a lower frame rate. When transmitting data, the console device .3 retains fewer buffers (even setting the buffer to zero). The control device 3 can obtain a lower delay time (uw lateney delay) e, the control device 3 receives the data and decomposes the domain, and can play the transmission at a synchronous speed due to the characteristics of the low delay time.

Furthermore, the transmitting device 1 transmits the data x playback buffer 2 retains a buffer larger than the buffer reserved by the control device 3. [0026] 100108922 The step of the step S48, the non-shai console device 3 returns the internal frame digesting condition (Frame Dise <?+1·1〇n Acknowledge) to the transmitting end loading ha^S5〇) The transfer device 1 adjusts the digestive condition used in the second encoding by adjusting the digestive condition of 3 1002015101-0 201240467 back to 1 according to the control terminal loading page 11/total 23 page form number A0101 (step S52). In the invention, the control device 3 is mainly a hand-held electronic device, and the processing performance of the handheld electronic device is generally not as high as that of the smart TV or the expansion connection device 4. Therefore, the purpose of this step is to confirm the processing speed and progress of the console device 3, thereby ensuring that the console device 3 can be synchronized with the transmitter device 1 to keep the user in "what you see is what you get". status. [0028] Next, the control terminal device 3 determines whether a control event occurs (step 4), and if so, the control device 3 immediately transmits a control signal to the transmitting device 1 'to enable the transmitting terminal The frame rate used by the second encoding is increased (step S56) to facilitate the user to manipulate the console device 3. The value is mentioned as 'the transmitter device! In this case, two different commas are simultaneously loaded with a relatively high load (〇verhead). In this step S56, the parameters of the first coding and the second coding are dynamically adjusted according to whether the control event of the control terminal device 3 is triggered or not, and it is determined that the transmitting end device 1 is fully capable of being the control terminal device 3. The performance is optimized and the performance of the playback device 2 is moderately sacrificed. Therefore, two different catering loads are performed when the transmitting device is reduced. However, the above description is only a preferred embodiment of the present invention' and should not be limited thereto. After the step S56, the control terminal device 3 transmits a corresponding control command to the transmitting device to control the operation of the transmitting device i (step S58). More specifically, when the touch screen 31 to which the control terminal device 3 is attached or the physical button 32 is touched, it is determined that a control event occurs. In the step S58, the control device 3 controls the absolute coordinate or the opposite coordinate on the touch screen 31, and transmits it to the transmitting device 1 to 100108922.

In addition, the control device 3 also scans the key of the entity _32 or finely transmits the uniC0 input through the touch screen 31 or the physical button 32 (the string is transmitted to the transmitting device 1 and converted into the The control command of the keyboard of the transmitting device! However, the above description is only a preferred embodiment of the present invention, and should not be limited thereto. If in this step S54, it is determined that the control device 3 is not within the predetermined period. If a control event occurs, the transmitting device reduces the frame rate used by the second encoding, or sets the frame rate used for the second encoding to zero (step S60). More specifically, the control device 3 Mainly for the processing capacity is weak 'and need to use the battery as the power of the device:, set. Long-term transmission and decoding action will not only waste the transmission bandwidth of the console device 3, but also consume a lot of power. The purpose of step S60 is to dynamically adjust the parameters of the first code and the second code to reduce the load of the two different codes simultaneously by the transmitting end device 1 while saving the transmission bandwidth of the control terminal device 3, and Decoding In the remote video sharing method of the present invention, the transmitting device 1, the playing device 2 and the controlling device 3 establish a connection with each other through execution of the applications 1, 20 and 30. More specifically, after one of the applications 1 , 20 or 30 is executed, the IP address of the other application is searched for, and the connection is established through the WIFI, and the data is transmitted to each other. The playback device 2 and the console device 3 determine whether the applications 10, 20, and 30 are turned off at any time (step S62), and when one of the applications 10, 20, and 30 is turned off. Disconnecting the connection, ending the remote video sharing method of the present invention. More specifically, page 13 of 23 form number A0101 1002015101-0 201240467, when the application 10 is closed, the transmitting device 1 is disconnected a connection between the playback device 2 and the control device 3; when the application 20 is closed, the playback device 2 disconnects the connection with the delivery device 1, but the delivery device 1 and the control device 3 The connection is still working When the application 30 is turned off, the control device 3 disconnects the connection with the transmitting device 1, but the connection between the transmitting device 1 and the playback device 2 continues to operate. [0032] After the applications 10, 20, and 30 are all working normally, the device 10 returns to the step S40, and the transmitting device 1 continuously captures its own screen and sound, and transmits it to the player device 2 and the console device 3 for playback. The control command of the control terminal device 3.
