Abstract

The present invention relates to a new 3D TV receiver that can receive and decode a 3D TV broadcast signal that compresses and encodes left and right moving image data received from two left and right cameras in order to express a three-dimensional effect of a screen.

The biggest difference between existing digital TV broadcasting and 3D TV broadcasting is classified according to whether the three-dimensional effect of the screen can be expressed. In order to express a three-dimensional effect, two left and right cameras corresponding to the left and right eyes are required, and since data is input through the two left and right cameras, the data to be processed is doubled compared to the existing digital TV broadcasting data, and the processing capability of the broadcasting system is increased. About twice as much.

In particular, in the case of using a more complicated H.264 coding method [Document 2] in addition to the MPEG-2 coding method [Document 1] used in existing digital TV broadcasting, the processing power is required to be more than doubled.

Similarly, the 3D TV receiver requires at least twice as much data processing capacity as conventional digital TV reception, and this requires a high performance dedicated decoding processor that is more powerful than the decoding processing processor used for digital TV reception. However, since there is no dedicated decoding processor that can decode 3D TV broadcast data, and it is difficult to implement it in a short period of time, it may be a problem to spread 3D TV broadcast service early.

In order to solve the above problems, instead of using a 3D TV dedicated decoding processor, the present invention allows a 3D TV broadcast signal to be decoded early by decoding the 3D TV encoded data using a tablet PC that already has a high-performance processor. It is intended to provide a new device and method that can process reception.

To this end, the tablet PC-based 3D TV receiver of the present invention includes a digital TV receiver, a wireless LAN connection unit, and a tablet PC.

According to the present invention, it is possible to easily configure a 3D TV receiver using a tablet PC without using a 3D TV dedicated decoding processor to receive and process a 3D TV broadcast signal. It can be usefully used.

ITU-T Recommendation H.264 (2003), "Advanced Video Coding for generic audiovisual services" | ISO / IEC 14496-10: 2003, "Information technology, Generic coding of audio-visual objects-part 10: Advanced video coding"

Unlike conventional digital TV broadcasting, 3D TV broadcasting requires two left and right cameras corresponding to left and right eyes in order to express a three-dimensional effect, and data to be processed compared to existing digital TV broadcasting data because data is input through two left and right cameras. Is doubled, and the processing power of the broadcasting system is about doubled.

In particular, in the case of using a more complicated H.264 coding method [Document 2] in addition to the MPEG-2 coding method [Document 1] used in existing digital TV broadcasting, the processing power is required to be more than doubled.

Similarly, the 3D TV receiver requires at least twice as much data processing capacity as conventional digital TV reception, and this requires a high performance dedicated decoding processor that is more powerful than the decoding processing processor used for digital TV reception. However, since there is no dedicated decoding processor that can decode 3D TV broadcast data, and it is difficult to implement it in a short period of time, it may be a problem to spread 3D TV broadcast service early.

In order to solve the above problems, instead of using a 3D TV dedicated decoding processor, a 3D TV broadcast signal is received early by decoding 3D TV encoded data using a tablet PC that already has a high-performance processor. It is to provide a new device that can be processed.

To this end, a tablet PC-based 3D TV receiver of the present invention includes a digital TV receiver, a wireless LAN connector, and a tablet PC, and the 3D TV broadcast data received through the digital TV receiver and the wireless LAN connector is a tablet. Decoding is performed using a PC built-in processor. It is well known that processors embedded in tablet PCs are generally capable of parallel processing at high speeds, and are much more powerful than dedicated processors used for specific purposes, making it easier to process 3D TV broadcast data in real time. Do.

Accordingly, the tablet PC-based 3D TV receiver of the present invention includes a digital TV receiver for receiving a 3D TV broadcast signal, a wireless LAN connection unit for transmitting the received 3D TV broadcast data to a tablet PC through a wireless LAN, and a wireless LAN. And a tablet PC for decoding the received 3D TV broadcast data, restoring original left and right video data, and outputting the same to the 3D display.

According to the present invention, it is possible to easily configure a 3D TV receiver using a tablet PC without using a 3D TV dedicated decoding processor to receive and process a 3D TV broadcast signal. It can be usefully used.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle of the preferred embodiment of the present invention.

1 is a block diagram of a tablet PC-based 3D TV receiving apparatus according to the present invention.

The tablet PC-based 3D TV receiver of the present invention includes a digital TV receiver 11 for receiving a 3D TV broadcast signal, a wireless LAN connector 12 for transmitting the received 3D TV broadcast data to a tablet PC through a wireless LAN, And a tablet PC 13 which decodes the 3D TV broadcast data received through the WLAN to restore original left and right video data and outputs the same to the 3D display.

The digital TV receiver 11 receives the 3D TV broadcast signal, converts it into a digital data form, and transmits the same to the WLAN connection unit 12. The digital TV receiver 11 is implemented using a commercial digital TV receiver module as it is used to receive an existing digital TV. The 3D TV broadcast signal is created by adding information (for example, right camera input information) that can express a three-dimensional effect while maintaining the existing digital TV broadcast signal form. That is, the form of the 3D TV broadcast signal is the same as the reference digital TV signal, and only the information content is different. Therefore, it is possible to receive a 3D TV broadcast signal using the existing digital TV receiving module as it is.

The WLAN connection unit 12 converts the 3D TV broadcast data received from the digital TV receiver 11 into a WLAN transmission format and transmits the 3D TV broadcast data to the tablet PC through the WLAN. The wireless LAN connection unit 12 is implemented using a commercially available wireless LAN module, and does not process the contents of the 3D TV broadcasting data received from the digital TV receiving unit 11 without changing the contents of the 3D TV broadcasting data. It serves to convey.

In addition, the digital TV receiver 11 and the wireless LAN connector 12 are located in the same board or stacked board form because signals to be transmitted must be closely connected.

The tablet PC 13 decodes the 3D TV broadcast data received through the WLAN to restore original left and right video data input from two cameras. As a decoding method used for restoring the left and right moving image data, the MPEG-2 method [Document 1], the H.264 method [Document 2], and the like used in digital TV broadcasting are used. In addition, the tablet PC 13 may restore audio data in addition to moving image data. The decoding processing of the 3D TV broadcast data is entirely implemented in software using a processor built in the tablet PC 13. The reconstructed left and right moving image data is output to a 3D display to express a three-dimensional effect, and the reconstructed audio data is output to a speaker to output sound.

In addition, when the digital TV receiver 11 receives the 3D TV broadcast signal, it is necessary to select a specific channel among several channels. The channel selection information necessary for this is digitally transmitted from the tablet PC 13 through the wireless LAN transmitter 12. It is delivered to the TV receiver 11.
