Image processing device, video playing system and method for remotely controlling television and computer program product

The invention relates to an image processing device, a video playing system and a method for controlling the same at a remote end, in particular, an image processing device capable of synchronously playing and playing images on different devices, a video playing system and a method for controlling the television at the remote end.

With the advancement of technology, the application of today's handheld devices has become very popular, and the software available for handheld devices is also increasing. In the prior art, the screen of the handheld device can be displayed on the television screen via a transmission line or a wireless network, so that the television screen can simultaneously display pictures or movies in the handheld device. The user changes the image of the television screen through the handheld device.

This mode of thinking has been used at present, and the main purpose is that because the screen of the handheld device is small, it is broadcast through a large screen (such as a TV), that is, it is hoped that there will be a "big screen display small screen" thinking. Because hand-held devices are currently the most popular smart phones and PADs, when the small screen of the handheld device changes, the large screen changes, and the handheld device looks like a remote control. In fact, the small screen is transmitted to the large screen. The screen therefore has this illusion.

Of course, the traditional approach has its advantages and good applications. However, in some applications, traditional practices may not be appropriate. For example, many people have handheld devices, and everyone can't control the big screen through their handheld devices. On the other hand, since the handheld device needs to compress the image data when transmitting the image to the large-screen image device, the hand-held device requires a considerable amount of hardware resources, including battery resources, which is very disadvantageous for the handheld device.

In addition, if the user wants to make a call, the image of the big screen cannot play the original video but the interface of the call, which causes a lot of inconvenience, especially when many people are watching the big screen.

The main object of the present invention is to provide an image processing apparatus having the effect of simultaneously playing back and playing images on different apparatuses.

Another main object of the present invention is to provide a video playback system having the above image processing apparatus.

Yet another primary object of the present invention is to provide a method of remotely controlling a television using the above described apparatus.

In order to achieve the above object, the image processing apparatus of the present invention allows the user to remotely control the television through the touch screen of the handheld device, thereby transmitting the image broadcast data to the handheld device. The image processing device includes a first signal transmission port, a second signal transmission port, a processor, a memory, and a third signal transmission port. The first signal transmission is used to receive image broadcast data. The second signal transmission port is used to connect to the television.

Next, at the image processing device 10, S2 is performed: the synchronization request signal is received from the handheld device by the image processing device.

At this time, the image processing apparatus 10 uses the third signal transmission port 15 to receive the synchronization request signal from the handheld device 30.

Next, S3 is performed: compressing the image broadcast data by the image processing device.

Then, the processor 11 of the image processing apparatus 10 uses the software program 121 to compress the video broadcast data broadcasted by the television 20 to obtain video broadcast data having a low traffic rate. For example, the video broadcast data is converted into a video stream file, and the video stream file can be an H.264 stream format. However, the present invention is not limited to such a format, and the compression ratio can also be determined according to the bandwidth of the network.

S4 is further performed: the image broadcast device transmits the image broadcast data to the handheld device.

After the processor 11 compresses the video play data, the processor 11 transmits the video play data to the handheld device 30 via the third signal transmission port 15.

Then, at the handheld device 30, S5 is performed: the image broadcast data is acquired.

Then, at the end of the handheld device 30, the video broadcast data transmitted via the third signal transmission unit 15 can be obtained.

Simultaneously, S6: adjusting the image size of the image broadcast data according to the specifications of the handheld device.

While receiving the image broadcast data, the adjustment module 32 of the handheld device 30 automatically adjusts the image size of the image broadcast data according to the specifications of the handheld device 30 itself.

Then proceed to S7: synchronously display the video broadcast data.

After the above steps are performed, the handheld device 30 can display the video broadcast data on the touch screen 31.

Then, the handheld device 30 can perform S8 again: the user operates the touch screen to generate a control signal.

Then, if the user wants to change the replacement image, the user can operate the touch screen 31 again, thereby generating a new control signal.

S9 can be performed: the control signal is transmitted.

The handheld device 30 can then transmit the newly generated control signal to the image processing device 10 via the third signal transmission port 15 .

Therefore, the image processing apparatus 10 performs S10: the control signal transmitted by the handheld device is received by the image processing apparatus.

Thereby, the image processing device 10 can obtain a new control signal via the third signal transmission port 15 .

Finally, S11 is performed: according to the control signal, the image processing device is configured to process the video broadcast content to obtain a new image broadcast data.

Finally, the processor 11 of the image processing apparatus 10 uses the software program 12 to adjust the video broadcast content according to the control signal to obtain new video broadcast data from the first signal transmission unit 13. In this way, the new video broadcast data can be displayed on the television 20 via the second signal transmission port 14 and synchronously displayed on the handheld device 30 via the third signal transmission port 15 .

It should be noted that the method for remotely controlling the television of the present invention is not limited to the above-described sequence of steps, and the order of the above steps may be changed as long as the object of the present invention can be achieved.

The video playback system 1 of the present invention and the remote control television method thereof can control the video broadcasted by the television 20 by using the touch screen 31 of the handheld device 30, and simultaneously display the video broadcast data, and can be more Efficiently transferring data and dramatically reducing network traffic does not take up too much network bandwidth.

To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examination and express the patent as soon as possible. It should be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the invention is intended to be limited by the scope of the claims.
