Embodiment 1

[0039] figure 1 It shows the structure of a TV set that plays different programs at the same time provided by the first embodiment of the present invention. For the convenience of description, only the parts related to this embodiment are shown, wherein:

[0040] The signal demodulation decoder 11 is configured to demodulate and decode the received signals of the two programs, and acquire video data of the two programs.

[0041] In this embodiment, after the television receives signals of two different programs, it demodulates and decodes the received signals of the two programs, so as to obtain video data corresponding to the signals of the two programs.

[0042] The data resolution adjuster 12 is configured to adjust the resolution of the acquired video data of the two programs.

[0043] In this embodiment, the resolutions of the video data of the two programs are adjusted, for example, the acquired resolutions of the video data of the two programs are both adjusted to half...

Embodiment 2

[0052] figure 2 It shows another TV structure that plays different programs at the same time provided by the second embodiment of the present invention. In this embodiment, the TV includes the signal demodulation decoder 11, the data resolution adjuster 12, the Data interleaver 13 , enabler 14 and display 15 .

[0053] In this embodiment, the data interleaver 13 includes a parity column data divider 131 and a parity column data filler 132 .

[0054] The odd-even column data divider 131 is used to divide the data frame of the display into even-numbered columns and odd-numbered columns.

[0055] In this embodiment, the video data of the two programs whose resolutions have been adjusted are filled with odd and even columns for subsequent processing.

[0056] The odd-even column data filler 132 is used to fill the video data of one program into the odd-numbered columns of the display frame, and fill the video data of another program into the even-numbered columns of the display...

Embodiment 3

[0067] Figure 4 The flow of a method for simultaneously playing different programs provided by the third embodiment of the present invention is shown, and the details are as follows:

[0068] Step S41, demodulate and decode the received signals of the two programs, and obtain the video data of the two programs.

[0069] Step S42, adjusting the resolutions of the acquired video data of the two programs.

[0070] Step S43, interleaving the video data of the two programs whose resolutions have been adjusted.

[0071] Step S44, driving the screen electric field to control the rotation of the liquid crystal molecules in the screen glass with the protrusions at an angle, so as to separate the video data of the two interwoven programs.

[0072] In this embodiment, there are protrusions with angles in the upper and lower screen glasses of the TV set. Before the TV is started, the liquid crystal molecules in the screen glass are perpendicular to the plane of the screen glass, and on...

Abstract

The invention is suitable for the field of signal processing, and provides a television (TV) and method capable of simultaneously playing different programs. The TV comprises a signal demodulation decoder for demodulating and decoding signals of two programs to obtain video data of the two programs, a data resolution adjustor for adjusting the resolutions of the video data of the two obtained programs, a data interleaver for interleaving the video data of the two programs subjected to resolution adjustment, a starter for driving a screen electric field and controlling a liquid crystal molecule to rotate in the screen glass of a projection with an included angle so as to separate the video data of the two interleaved programs, and a display for displaying the video data of the two programs which are separated after the refraction of the liquid crystal molecule and emitting the video data to two different positions. According to the embodiment of the invention, two different programs can be simultaneously played, and the good experience of a user can be improved.

Description

technical field [0001] The invention belongs to the field of signal processing, and in particular relates to a TV set and a method for playing different programs at the same time. Background technique [0002] With the development of TV technology, new functions of TV sets are also more and more diversified, such as playing different TV programs on the same TV set. [0003] When using a TV set at home, it often occurs that different family members need to watch different TV programs. To meet the needs of watching different programs at the same time, you may need to buy multiple TVs or use the traditional picture-in-picture method. If you buy multiple TVs, not only the cost is high, but also it will cause a waste of idle TVs when you don’t need to watch them; When the size of the TV screen is fixed, the display areas of the two programs cannot be made large, so that the family members watching the TV cannot be satisfied at the same time. The technology of time-sharing viewi...
