The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Detailed ways

The remote controller in the present invention and the television system using the remote controller will be further described in detail below with reference to the accompanying drawings.

Referring to Fig. 1 and Fig. 2, the TV system (hereinafter referred to as TV system) 1 capable of playing different channels simultaneously includes a LCD TV 2, a set-top box 3, at least two shutter glasses 4 and a remote controller 5. The remote control 5 is used to remotely control the LCD TV 2 and the set-top box 3 in response to user input operations.

In this embodiment, there are two shutter glasses 4 , which are shutter glasses A and shutter glasses B respectively. The two shutter glasses 4 are wirelessly connected with the set-top box 3 . The set-top box 3 can obtain the audio and video data streams of two TV channels from the outside (such as a broadcast TV network), and control the screen of the LCD TV 2 to continuously alternately switch and display the video images of the two channels. In this embodiment, the set-top box 3 also adds a channel mark to the received audio and video data streams of each channel, so as to distinguish audio and video data of different channels. In this embodiment, the two channels played at the same time are respectively defined as channel 1 and channel 2, and A1, A2...An are several frames played sequentially by channel 1, and B1, B2...Bn are channels 2 sequentially play several frames of pictures, then the set-top box 3 controls the picture played by the LCD TV 2 to be A1B1A2B2A3B3.... In the present embodiment, when the LCD TV 2 is playing two different channels at the same time, the refresh rate of its screen is twice the refresh rate when only one channel is played, so that the screen of each channel played simultaneously is clear and continuous. At the same time, the LCD TV 2 is in a silent state when playing different channels at the same time.

Each shutter glasses 4 includes a radio frequency identification (RFID) tag (not shown) and a shutter switch (not shown), wherein the radio frequency identification tag is used to identify the shutter glasses 4, and the shutter switch is used to control the opening of the shutter glasses 4 And off, when the shutter glasses 4 are in the open state, the shutter glasses 4 can watch the picture displayed by the LCD TV 2, and when the shutter glasses 4 are in the closed state, the picture displayed by the LCD TV 2 cannot be seen.

The remote control 5 includes an input unit 51 , an identification unit 52 , a storage unit 53 and a processing unit 54 . The input unit 51 is used for receiving user's input operation.

The identifying unit 52 sets an action range for identifying the radio frequency identification tags in the shutter glasses 4 within the action range, so as to identify different shutter glasses 4 . In this embodiment, the working range of the identification unit 52 is 30-60 centimeters.

The storage unit 53 stores the radio frequency identification tag corresponding to each shutter glasses 4 and the corresponding relationship between each broadcast channel and the channel label. When the user wearing the shutter glasses 4 is within the range of action of the recognition unit 52, the channel to be watched can be selected through the input unit 51 of the remote controller 5, and the processing unit 54 obtains and stores the channel identification corresponding to the channel to be watched. The corresponding relationship between the shutter glasses 4 and the selected channel logo, send the channel logo to the corresponding shutter glasses 4, generate a selection command with the channel logo and send the selection command to the LCD TV 2 and the set-top box 3. For example, when a user wearing shutter glasses A wants to watch channel 1, he inputs and receives a selection signal of channel 1 through the remote controller 5, and the remote controller 5 sends the channel indication of channel 1 to the shutter glasses A, and at the same time sends the The selection signal of the channel label of the channel is sent to the set-top box 3; when the user wearing the shutter glasses B inputs the selection signal of the channel 2 through the remote control 5, the remote control 5 will send the channel label of the channel 2 to the shutter glasses B, and at the same time the belt The selection signal marked with the channel 2 is sent to the set-top box 3 .

After the set-top box 3 receives the selection instruction from the remote controller 5, when controlling the liquid crystal television 2 to switch and display the pictures of the two channels, it also generates a synchronous control signal for controlling the shutter glasses 4 that watch the corresponding channel to be opened and closed in an interlaced manner. The synchronization control signal is synchronized with the picture played by the LCD TV 2 . The synchronous control signal also includes a channel indicator, which indicates the currently played channel, which corresponds to the channel currently watched by the shutter glasses 4. Therefore, for the shutter glasses A and the shutter glasses B, the channels they watch are different. The corresponding synchronous control signals are also different. The set-top box 3 also adds a corresponding channel label to the audio data of each channel. When the set-top box 3 controls the LCD TV 2 to continuously interleave the images of two channels, it also transmits the synchronous control signal and the audio data stream with the channel label to each shutter glasses 4 in a wireless manner.

Each shutter glasses 4 controls a shutter switch (not shown) to be turned on and off according to a synchronous control signal with the same channel label. For example, the shutter glasses A that chooses to watch channel 1 controls the shutter switch to switch on and off in turn according to the synchronous control signal with the channel label of channel 1... so the pictures that the shutter glasses A watches on the LCD TV 2 are A1, A2 , A3 . . . , and receive an audio data stream with a channel designation of channel 1. Similarly, the shutter glasses B that choose to watch channel 2 control the shutter switch to turn off and on in sequence according to the synchronous control signal marked with channel 2, so that the pictures that the shutter glasses B watches on the LCD TV 2 are B1, B2 , B3..., and receive the audio data stream marked with the channel 2, so that different users can simultaneously watch TV programs of different channels on the same LCD TV 2 by wearing different shutter glasses 4 . In this embodiment, each shutter glasses 4 is connected to an earphone (not shown) to listen to the audio corresponding to the watched channel synchronously.

In this embodiment, the remote controller 5 is also used to identify the shutter glasses 4 within its effective range through the identification unit 52 when the user wearing the shutter glasses 4 to watch a TV program needs to switch the channel he watches. 54 According to the corresponding relationship between the radio frequency identification tag of the shutter glasses 4 stored in the storage unit 53 and the broadcast channel label, in response to the user's input operation, generate a control instruction for switching the broadcast channel corresponding to the shutter glasses 4, and send The control command is sent to the LCD TV 2 and the STB 3 . Wherein the control command includes the channel label of the broadcast channel corresponding to the shutter glasses 4 . After the set-top box 3 receives the control instruction including the broadcasting channel label, it correspondingly performs switching control on the channel with the channel label, and at the same time controls the LCD TV 2 to switch accordingly. At the same time, the storage unit 53 stores the corresponding relationship between the radio frequency identification tag of the switched shutter glasses 4 and the channel label of the watched channel. When the channel received by the shutter glasses 4 changes, the corresponding channel label also changes accordingly. For example, when a user wearing shutter glasses A picks up the remote controller 5 to perform an input operation, and wants to switch channel 1 currently watched by the shutter glasses A to channel 3, the identification unit 52 first identifies the radio frequency identification tag of the shutter glasses A, The processing unit 54 determines that the channel 1 is currently watched by the shutter glasses A according to the corresponding relationship between the radio frequency identification tag stored in the storage unit 53 and the broadcast channel, and responds to the user input operation to generate a switching instruction including the channel 1 label, and sends the A switching instruction including channel 1 is sent to the set-top box 3 , and at the same time the processing unit 54 changes the playing channel corresponding to the radio frequency identification tag of the shutter glasses A stored in the storage unit 53 to channel 3 . The set-top box 3 determines that the channel to be switched is channel 1 according to the channel label in the switching command, and correspondingly changes the audio-video signal received from channel 1 to the audio-video signal received from channel 3, and the LCD TV 2 switches the picture of channel 1 It is the picture of channel 3. Therefore, the channel watched by the user wearing the shutter glasses A is switched to channel 3, while the channel 2 watched by the user wearing the shutter glasses B does not change. Apparently, the user can also control the LCD TV 2 through the remote controller 5 , such as controlling the brightness and contrast of the LCD TV 2 .

According to the above description, in the embodiment of the present invention, when multiple users watch TV programs of different channels on the same LCD TV 2 simultaneously by wearing different shutter glasses 4, the remote controller 5 can automatically detect the users, And in response to the user's operation, the channel that the user is watching is controlled without affecting the channels watched by other users.
