Detailed ways

Referring to FIG. 1 , the system of the present invention includes a channel controller 110 , a gateway 120 , and an audio-visual player 130 . Wherein the channel controller 110 is responsible for receiving the control signal for controlling the music image, and transmitting the received control signal to the gateway 120, and when receiving the music image transmitted by the gateway 120, forwarding the music image to the audio-visual playback device 130 Display; the gateway 120 is responsible for receiving the control signal sent by the channel controller, and when judging that the received control signal is the playback signal of the music video, it transmits the music video to the channel controller 110, and the audio-visual playback device 130 is responsible for receiving the signal controlled by the channel. The music image transmitted from the device, and display the received music image to the user.

Next, an embodiment is used to illustrate the operating system and method of the present invention. In this embodiment, the channel controller 110 is an example of a digital video converter box, and the audio-video player 130 is an example of a digital TV.

Referring to Fig. 2, when the user wants to use the present invention, at first can use the remote control to select a song and press the play button, the remote control will send a control signal represented as a play signal to the digital video conversion box 110, digital video conversion The box 110 will receive the control signal (step 210), and after receiving the control signal, the digital video conversion box 110 will send the control signal to the gateway 120 (step 220), and execute it on the gateway 120 in the form of ActiveX The music video playback control program will determine whether the control signal received by the gateway 120 is a playback signal. Wherein, the music and video playback control program mentioned in the present invention is not limited to be executed in the manner of AcitveX, and may also be executed on the gateway 120 in other manners such as resident programs.

Since the control signal sent by the user is a playback signal, the music video playback control program executed in the form of ActiveX will determine that the control signal is a playback signal, so the music video playback control program will read and play the pre-stored gateway 120 The file of the music video, while playing the music video, the gateway 120 will obtain the music video (including picture and sound) played at that time, and transmit the acquired music video to the digital video converter box 110 (step 230), Since the method of acquiring video and audio is known, no further description is given here.

After the digital video converter box 110 receives the music video, it will transmit the received music video to the digital TV 130 (step 250), and the digital TV 130 will display the music video for the user to watch after receiving the music video.

Generally speaking, the gateway device 120 is not a device specially used to provide music images to the channel controller 110, so the gateway device 120 usually does not store music image files, so the music image playback control program determines that the control signal is a playback signal. , the request for downloading the music video will be sent to the music video server 190 storing the music video. The music video that the player wants to sing along) is returned to the gateway 120. After the gateway 120 receives the music video, it will play the music video downloaded by the music video server 120, and obtain the played music video and transmit the acquired music video to the The digital video converter box 110 (step 230 ), the digital video converter box 110 can transfer the music video to the digital TV 130 , so that the user can watch the music video they want to sing along on the digital TV 130 .

In this way, the present invention can solve the problem that the digital TV using the channel controller cannot use the network to download music images in real time to provide users with singing along.

In addition, when the user sings along with the music video displayed by the digital TV 130, he may use the remote controller to generate other types of control signals to control the presentation of the music video. After receiving the control signal, the control signal will be transmitted to the gateway 120 (step 220). After receiving the control signal, the music and video playback control program in the gateway 120 will judge the type of the control signal and adjust the playback according to the type of the control signal. Music video (step 240), for example, when the user feels that the pitch (Key) is too high, it can send a pitch adjustment signal (control signal) representing a degree of pitch reduction. After the music video playback control program receives the pitch adjustment signal, Then the pitch of the played music video will be lowered by one degree, so that the pitch of the music video obtained by the gateway 120 will be lowered by one degree according to the pitch adjustment signal; The program will amplify the volume of the music video played; when the user feels that the playback speed (Tempo) is too fast, a rhythm adjustment signal can be sent out, and the music video playback control program will reduce the playback speed of the subtitles and images in the music video, and reduce the tempo. According to the rhythm of the sound signal in the slow music image, the user can obtain the desired playback result.

In addition, here is a brief description of the method of making a pre-stored music video file. First, the video signal is sliced, for example, into 24 images per second, and then read at the same speed as the slice, that is, 24 images per second. And at this time, the subtitles corresponding to the video number and the audio signal are synthesized with the video signal, so that the file of the music video can be completed.
