Patent Application
20080139229
Many different applications for cellular phones are known. Cellular phones now are often equipped with MP3 players, video cameras, color display screens, and GPS tracking. Cellular phones promise wideband Internet access capability using Wimax and other analogous technologies to deliver streaming video, live television broadcasts and interactive gaming.
Images may be divided and shown on smaller screens. See, for example, U.S. Pat. No. 5,161,012, and application publication number 2003/0007564.
The present application teaches a special activity for multiple cellular phone users, which provides a cellular display which provides multiplex viewing.
The general structure and techniques, and more specific embodiments which can be used to effect different ways of carrying out the more general goals, are described herein.
The pieces of a motion picture or a message can be collectively viewed on the multiple different display screens. This way, when the screens are viewed together, the collective viewing provides the complete moving picture. However, no single display provides the whole picture.
This technique can be used for viewing videos, or for a new form of video game that can be played on multiple user screens, in which multiple users become the collective participants of a current game. By so doing, an entirely new paradigm of playing the game becomes possible. Another advantage of this system is that since the games or videos are often displayed on small screens, such as the small screen of a cellular phone, this system enables the overall viewing screen to be larger than any single viewing screen.
The present application shows using multiple different display screens on multiple different phones.
The image is sent 105 as an electrical signal to a digital separator 110. The digital separator 110 parses the image into a number of different component parts. For example, the image may be broken up into different component parts that are not connected to each other as in
Within the screen 100, note that the H letter 106 is totally disconnected from the E letter 107. The separator may use various kinds of digital processing techniques to separate the overall screen 100 into a number of different sub screens of a type that can each be displayed on different small screens. The separated image 115 is sent from the cellular transmitter 122 to a number of different receivers, shown collectively as 130. Each receiver, such as 131, receives only a part of the overall message. For example, 131 receives the letter H, while 132 receives the letter E. Collectively, all of these devices receive the entire image, and it is displayed separately.
In an embodiment, this system may bridge different cellular phone networks by sending portions over different networks.
In the embodiment, a video transmission can be displayed on several cellular display screens simultaneously, in a way such that if the various displays are held side-by-side in the proper arrangement, they form a recognizable image of a combination of the collective smaller images.
The separation done by the digital separator 110 can select the number of separations. Alternatively, this can be selected by the number of people who are attempting to collectively view the media e.g. a video or an image. In an example where all the participants can all view each other's cellular phone display screens simultaneously, the original picture may be fragmented into as many pieces as there are participants. There may be 100 or 500 persons for example, or, as in the example shown in
In one embodiment, the participants cannot necessarily view each other participant's display screens, and there may be many more participants.
A video image can be divided up into random parts like a jigsaw puzzle when many display screens are used in this way.
An important issue may be pixel conversions. A cellular display screen may display in the range of 100's by 100's of pixels per frame, while a high definition television program may display 1920 by 1080 pixels. So while the High Definition TV requires 2 million pixels per frame, a cellular phone display may display 96×80 pixels, or 1/270th the number of pixels as in the HDTV.
More modern cellular phone displays may have 10 times more, for example 240×320 pixels per frame. Still, even with these most modern display screens, the phone has a very small fraction of the number of pixels in the larger phone.
Take an example of a surfer riding a surfboard in the ocean. That 2 million pixel per frame HDTV image could be reduced into 270 parts. However most of those parts would simply show various shades of blue images representing the blue water of the ocean. Only a few of the parts would show the image of the surfer and the surfboard.
The parts showing only the ocean would change very little from frame to frame. However, the surfer's image on the few screens it appears, would move quite a bit as the surfer moves through the waves. Motion estimation techniques can hence be used to reduce the amount of information that is sent for the background, in order to minimize bandwidth consumption. Moreover, the part of the system that is moving, the surfer riding the surfboard between different screens, would produce quite a lot of interest as the surfer moves between the different screens of the different cellular phone users.
Action video clips would also produce interest. The background images in such a video clip such as a high-speed car chase are predominantly in motion. Since these are not static, a less aggressive compression method might be used for these background images.
In an embodiment shown in
Another embodiment uses these multiple screens to piece together a puzzle.
At 225, one image is sent to each participant user's display screen. 230 illustrates each user seeing the display and entering a digit to signify that user is active and viewing the screen. If the digit is not received by the controller for the digital separator 110, it assumes that user is not active, and either adds a new user, or re-formulates the image to fit on fewer screens.
For a game embodiment, the system notes that as the video progresses, the moving part of the image is eventually sent to all the participants' display screens. Each participant is prompted at 240 to press a key to play the game. At the end of the time interval at 245, the controlling computer determines the winner of the game, based on the interaction. For example, each user may be required to enter a key every time they see the actor or moving part come onto their screen, or whenever the actor takes a specified pose on their screen. As an alternative, the game may be totally locked, where the system counts each time the actor comes on the screen. Eventually, the player with the highest count wins the game. The winner is notified at 250, and prompted at 255 to electronically claim a prize.
301 to 310 represents x participants joining. As in
The above has described many users enrolling to obtain the information on their cellular phones, but it should also be understood that other techniques can be used such as determining which cellular phones have been turned on, or which have dialed a number, or the like. The process of determining how many phones are seeing the image or video may be totally automated.
The control circuits can send static images to all participant's display screens at 330. 335 illustrates how user number 1 sees a moving image but 340 shows how the image can move from user 1's screen to user 2's screen, at which point 345 illustrates user 1's display screen going static. 350 illustrates the process continuing. In other words, the actor may move from screen to screen.
Although only a few embodiments have been disclosed in detail above, other embodiments are possible and the inventors intend these to be encompassed within this specification. The specification describes specific examples to accomplish a more general goal that may be accomplished in another way. This disclosure is intended to be exemplary, and the claims are intended to cover any modification or alternative which might be predictable to a person having ordinary skill in the art. For example, other forms of breaking up the image are contemplated, and other clients are contemplated.
Also, the inventors intend that only those claims which use the words “means for” are intended to be interpreted under 35 USC 112, sixth paragraph. Moreover, no limitations from the specification are intended to be read into any claims, unless those limitations are expressly included in the claims. The computers described herein may be any kind of computer, either general purpose, or some specific purpose computer such as a workstation. The computer may be an Intel (e.g., Pentium or Core 2 duo) or AMD based computer, running Windows XP or Linux, or may be a Macintosh computer. The computer may also be a handheld computer, such as a PDA, cellphone, or laptop.
