RU2500042C2 - Television receiver display - Google Patents

Abstract

FIELD: physics.

SUBSTANCE: surface of the television receiver display is ribbed. Said ribs are straight triangular prisms passing from the bottom upwards on the entire height of the display, the lateral faces 1 and 2 of said prisms directed to the left side and the right side at an angle. An image of one television program is broadcast on the left faces 1 of the prisms and a second image is broadcast on the second faces 2. A full size image is formed on each of the composite half-screens, hence viewers located in lateral zones perpendicular to the plane of the faces will only see one video image formed on faces of the prisms facing them. Accompanying sound is transmitted at two separate outputs connected to headphones or extension loudspeakers. Each part of the screen is controlled using its own remote control device without affecting the second part of the display.

EFFECT: broader functional capabilities owing to simultaneous viewing of two full-size video images obtained from different sources on a television receiver display without special glasses.

Description

The invention relates to electronic equipment and can be used in the manufacture of television displays capable of displaying two video images simultaneously.

With the development of technology, more and more television sources are becoming available to viewers. Receiving a television signal is possible not only from antenna or cable input, but also from other external sources, such as a VCR, DVD player, a USB device with flash memory, a personal computer, etc. In this regard, situations arise when different users want to watch different TV programs at the same time: news, a movie or a television series, a sports program, surf the Internet, play video games. At home, this situation is usually resolved by watching family members watching television in different rooms. But most often in a family there is only one large-screen TV, and it is in demand by all family members.

Known television receivers capable of displaying multiple video images on one screen at the same time.

One example of such a television receiver is Picture-in-Picture (PIP) technology, according to which a television receiver receives video from two input sources using two tuners, tunes to both programs and creates two video images at the same time. In this case, the main television image is displayed on the screen in full size, the second is shown on a reduced scale, covering part of the main one. Options for the implementation of PIP technology are presented in patents US 5438372 (A) from 01/08/1995, G09G 3/04, H04N 5/265, H04N 5/44, H04N 5/445, H04N 5/45, H04N 5/66, H04N 5 / 76, H04N 9/74; EP 0737007 (A2) from 09/10/1996, H04N 5/445, H04N 5/45; US 6212680 (B1) dated 04/03/2001, H04N 5/44, H04N 5/445, H04N 5/45, H04N 5/46, H04N 5/50; WO 0199436 (A2) dated 12/27/2001, H04N 5/445, H04N 5/45; US 2009109339 (A1) dated 04/30/2009, G06F 13/00, G06F 3/00, G11B 27/10, G11B 27/34, H04N 5/272, H04N 5/445, H04N 5/45, H04N 5/781, H04N 5/93, G06F; KR 20100003883 (A) dated 01/12/2010, H04N 5/445, H04N 5/45; CN 102726053 (A) dated 10/10/2012, H04N 21/2343, H04N 21/431, H04N 21/434, H04N 21/438, H04N 21/6377, H04N 21/658, H04N 5/44, H04N 5/45, H04N 5/50.

PIP technology allows you to display the contents of two video sources at the same time, but it has some disadvantages. Besides the fact that someone has to watch a mini-image, the viewer of the full-screen image also loses part of it under the PIP overlay, which causes some discontent. In addition, the parallel image is distracting, so most often this system is used as an auxiliary, for short-term viewing, for example, when you turn on the video or to search for channels.

Known designs of television receivers with the function of simultaneously displaying images of the same size by dividing the display into adjacent equal disjoint parts. This technology is called Picture-Out-of-Picture (POP). In the patents EP 0716543 (A2) dated 12.06.1996, H04N 5/44, H04N 5/445, H04N 5/45, H04N 5/46, H04N 5/66, H04N 7/01, H04N 9/74; US2001048482 (A1) dated 12/06/2001, G06F 3/14, G09G 5/14, H04N 5/04, H04N 5/45, H04N 5/46; US2002186212 (A1) dated 12.12.2002, G06F 3/14, G09G 5/14, G09G 5/36, H04N 5/445; CN 1791198 (A) dated 06/21/2006, H04N 5/445, H04N 5/45; GB 2450235 (A) dated 12/17/2008, G06F 3/048, G06T 15/20, H04N 5/445, H04N 7/18; US2009015716 (A1) dated 1/15/2009, H04N 5/445; US 7712117 (B1) dated 05/01/2010, H04N 5/445; JP 2011044974 (A) of 03/03/2011, H04N 5/445, describes the design of television receivers, providing for the possibility of simultaneous viewing of two video images of the same size, located on the display side by side. Although each image is smaller than the main TV screen, they are larger than the smaller in PIP technology. The left and right halves of the display can simultaneously display two different images having a higher resolution without overlaying one image on the other. To place them on the display, the width of each of the images is reduced by half, and their height is proportionally reduced by including empty bars above and below the image, i.e. each of the images in this case is reduced fourfold, users see both images much smaller than in full screen mode, to view them requires a corresponding change in the distance from the TV, which brings certain inconvenience.

Thus, the PIP and POP systems presented above solve the problem of simultaneously displaying multiple video images for different users on the same television receiver, however, the picture is much smaller than the full size of the display, low resolution reduces the quality of playback. In addition, parallel video is distracting.

In patents US 6188442 (B1) from 02/13/2001, H04N 13/00, H04N 13/04, H04N 5/44; US2004109093 (A1) dated 06/10/2004, H04N 13/00, H04N 5/44; US 2012050507 (A1) dated 03/01/2012, H04N 13/04, H04N 5/445, a method for simultaneously reproducing two full-size images, the separation of which uses special glasses, either shutter or mutually orthogonally polarized, is proposed. The indicated glasses are configured to view various contents, blocking certain frames in a pre-selected sequence, synchronizing with the display.

The disadvantage of this method is the need to use additional equipment - special glasses, which are often lost, they cannot be found at the right time. In addition, certain inconveniences appear in the viewer, who uses ordinary correction glasses when watching TV.

The aim of the invention is to develop a method and device for simultaneous full-size display on one display of two video programs received from different sources, and view them without the use of additional equipment.

The solution of the technical problem is provided by the fact that the claimed invention has developed the design of a television receiver that provides reception and full-size display on a single display of two video programs received from one or several sources and viewing them without using additional equipment.

The present invention is illustrated by a description of an example of its preferred embodiment with reference to the accompanying drawings. The same item numbers are used throughout the description and in all drawings to refer to the same components and parts.

The surface of the television display is ribbed. These ribs are straight triangular prisms extending from the bottom to the top of the entire display height, the side faces of which are directed to the left and right at an angle α / 2. An enlarged fragment of the display is shown in figure 1. The image of one television program is transmitted to the left faces of 1 prisms, and the second to the right 2. On each of the composite half-screens formed by the faces 1 and 2 of the prisms, a full-size image is formed, therefore, viewers located in the side zone 3 or 4 located perpendicular to the plane of the faces will see only one video image formed on the faces of the prisms facing them (Fig. 2). When viewing one program, it is displayed on both composite half-screens.

Sound is transmitted to two separate outputs to which headsets are connected, possibly wireless, or external speakers. Any number of wireless headsets can be used. Perhaps the soundtrack of one of the channels through the built-in speakers of the television receiver. Managing your part of the screen — switching programs, adjusting sound, switching external sources — is done using the remote control without affecting the second part of the display, so two remotes are included.

The essence of the claimed invention lies in the fact that it allows you to simultaneously display full-sized video on two composite screens of the same display of the television, for viewing which does not require special glasses. The user gets the opportunity, without turning off one program, read teletext to another, work on e-mail, chat or edit a Word document, look after a child watching a children's program.

The closest in technical essence to the claimed invention is the design of a display that reproduces two full-sized video images presented simultaneously in the patent US 2012050507 (A1) dated 01/01/2012, H04N 13/04, H04N 5/445, but special glasses are needed to separate them.

The technical result of the claimed invention is the ability to simultaneously view two full-sized video images on the display of a television receiver without special glasses.

The specified technical result is achieved due to the fact that the surface of the television display is ribbed. These ribs are straight triangular prisms extending from the bottom to the top of the entire display height, the side faces of which are directed to the left and right at an angle α / 2. The image of one television program is broadcast on the left faces of the prisms, and the second on the right. On each of the composite half-screens formed by the faces of the prisms, a full-size image is formed, therefore, viewers who are in the side zone located perpendicular to the plane of the faces will see only one video image formed on the faces of the prisms facing them.

New significant features of the claimed invention are:

- the ability to simultaneously view two full-size video images on the television receiver display without special glasses;

- the ribbed surface of the television display in the form of vertical straight triangular prisms;

- on each of the composite half-screens formed by the faces of the prisms, a full-sized video image is formed.
