p0001A portable remote PC pad

p0002description

p0003The invention relates to a portable remote PC pad for personal computers.

p0004Known are two types of Web pads. The first class, for example, a Siemens T-Sinus Pad, is limited to the remote transfer of Internet signals and required as hardware in a complete pad computer. These usually loaded non-PC operating systems and software, and must be maintained as a standalone system. The life cycle is as short as that of a set-top box, since the respective operating systems are evolving rapidly. Full PC functionality is missing mostly due to the limited hardware. It is just around mobile set-top boxes with a touch screen. Usually only a browser is offered as software and e-mail client and presentation software for some internet formats, such as audio / video.

p0005The second class, for example Scribor, no longer transmits the internet signal, but works with an intermediate standard PC. Its screen messages are compressed and transmitted those signals by radio to the pad. Conversely, the user inputs are transferred back. For decoding the compressed signals a considerable amount of hardware is necessary. However, the transmission speed of available frequency bands is too small for real video transmission, so that, for example films of the PC or the Internet are not transferable. Even to meet only parts of the tasks set out above, each additional and very powerful hardware previously required.

p0006The object of the invention to provide a portable remote PC pad for Personalcomputerzu, reached that maximum benefit at minimum cost per household. The software used should be compatible with the industry standard, modular exchangeable and retrofittable. Furthermore, PC-data should continue to be used seamlessly and to avoid redundancy errors not be duplicated. PC knowledge should remain usable omitted incorporation into new navigation systems.

p0007According to the invention the object is achieved by at least two sub-units, a device connected to the PC and the other device except home operable as Pad mobile within 50 meters (in-house) or 300 meters, which wirelessly between devices by radio a communication takes place, including the audio-video transmission from the video output card of the PC to the touchscreen video input of the pad, all programs and screen output via AV channel available on the PC will be visible on the pad.

p0008Presented thus a PC system is composed of a wireless audio video transmission link This invention enables the most economical realization of portable full Internet access on a display with resolution PC without the use of expensive digital Compressions- / and decompression. The PC control is possible with a keyboard and / or mouse simulation from afar. Hi is this feature please read at least uses a back channel consisting of a data transmission path between the pad as a data transmission round PC as a data receiver. This data is processed on the PC interface, eg RS 232, the PC as normal keyboard or mouse controls.

p0009The dependent claims relate to advantageous developments of the invention the subject.

p0010The portable remote PC pad can additionally a microphone in the pad and an audio transmission path from the pad as audio channels or to the PC as an audio receiver.

p0011Furthermore, a signal mixer may be provided in addition, of stirring up the data between the pad and the PC to the audio channel, and so a separate data radio link, namely transmitters and receivers, superfluous.

p0012Furthermore, the inventive remote PC pad may additionally comprise a SCART socket, which relays the video input of touch screens and receives video data from AV equipment.

p0013A further advantageous embodiment of the invention consists in an additional infrared transmitter on the pad. These are suitable to control TV, VCR, or mobile phones. The control signals are either in a separate radio link between the PC, ie data or infrared to radio stations, and pad, ie data receiver or converter radio to infrared, transmitted or mixed up on the audio signal and decodes the pad. Furthermore, an additional video backchannel will provided from the pad as a video transmitter to the PC as a video receiver. The video receiver is connected to the video input of the PC, such as the TV card. The video transmitter is connected to a webcam, which is integrated as an option on the pad or with the Scart socket of the pads.

p0014A further embodiment of the portable remote PC pad is characterized by an additional infrared receiver in the pad or in the PC-based box and additionally containing either a "infrared into data" converter, which uses its own data transmission path or the data Audio conversion is connected, or a separate infrared to Funksignalweg between pad as transmitters and PC as a receiver.

p0015According to another embodiment of the inventive solution all decoding and encoding tasks are replaced within the PC-based box by software running on the PC. Data outputs and / or infrared outputs are thereby mixed to the audio output already inside the PC. Likewise, the mixed-in audio input infrared and / or data signals are decoded within the PC by software in order to save hardware in the PC-based box.

p0016This solution is a cost-effective and simple hardware is created. Here an existing household hardware structure is involved, so double purchases are avoided. Additional required hardware integrates industry standards and enables a wide choice available devices. Proprietary hardware components are reduced to a minimum in order to make the rapid development in the technology sectors for the user available. The user can at the pad exercising his usual menu guidance and navigation, and upgraded its system arbitrarily with additional standard software. Due to the possible integration of standard software is achieved that also can access a wide and rapid new development of improved solutions.

As additional data sources date data streams such as teletext or Intercast services are to be integrated by the TV station, which also be searched by keyword.

p006115. Internet TV transmission source Bouquets

p0062The user should be able to choose the program sources regardless of the technical locations and delivery routes. It is intended to receive movies alternatively from the cable or via satellite on traditional broadcast channels, or can also play from the Internet-video sequences. The same applies to the integration of DVDs; VCR or video CDs.

p0063The following components are required according to the system presented in the household sector as the prior art:

p0064A PC or the possibility to install a PC in your study. On this PC the usual programs are installed, such as email, web browsing, word processing, multimedia player). In addition, the conventional hardware such as a printer, monitor, and input devices such as keyboard and mouse, installed.

p0065Even if a PC is not available yet, provides the inventive solution over proprietary Web pads a monetary advantage. In most cases the offered Web-pads are more expensive than a commercial standard PC as the hardware components are similar, but it is finished in smaller numbers. In addition, the web pad is good for nothing else, as opposed to the purchase of a PC. Now, the presence of a PC is required.

p0066On this PC a so-called base-Box 200 is installed. This box the size of a cigarette box contains little standard hardware, namely an AV transmitter and an optional AV receiver.

p0067The remote pad itself consists of a touch screen, ie keyboard and mouse simulation via touch, an AV receiver, a microphone and an audio transmitter, and an optional infrared transmitter and receiver. Optionally, along with a web cam, a video transmitter integrated.

p0068Both the base box, and the remote pad to send data, carried out by mixing the audio channel or separate channels, depending on the cost situation and received, by filtering out the audio channel or separate data receivers depending on the cost situation. Data can be control data or infrared commands.

p0069The fourth component of the system, a driver / software package is included, the software includes for different operating systems of household PC's.

p0070These five basic components are sufficient for a variety of household configurations to meet the above requirements.

p0071All other components are commercially available PC add-on "s, which - if not already - could be purchased separately: A TV card with the usual inputs and outputs (input: antenna cable; satellite cable, S-VHS; output: S-VHS or composites sit-Video) and the usual features: AVI Recording; MPEG2 Recording.

p0072A graphics card with TV-Out output (usually S-VHS or com- posit video) or if the user wants to continue to use his graphics card without TV output, a VGA2PAL or VGA2NTSC- converter between PC and PC base box is connected.

p0073The modular decomposition, the user need only purchase the components that it does not already own. Thus, for each household, the minimum cost solution illustrated above requirements is ensured. Duplicate purchase of hardware, within a household, is omitted. The overall system consists mainly of standard components, thereby further technical development and permanently affordable performance guarantees.

p0074The concept of the invention underlying will be described in more detail in the following description of an exemplary embodiment which is illustrated in the drawings. Show it:

p0075FIG. 1 is a schematic representation of the audio-video signal routing a PC base box and

p0076FIG. 2 shows a schematic representation of the portable remote pads.

p0077As seen in Fig. 1, allows the base box 200 to send audio and video signals from the PC 100, or possibly other sources such as satellite receivers, digital TV card, DVD player, etc., to the pad, or optionally via Seat plug to other AV-sinks such as video recorders, digital recorders, etc., and back. Optionally, the insertion of a VGA is> TV / CVBS converter possible.

p0078to be particularly mentions the connection of an IR Learn diode in Fig. 2. With the help of this diode can optional IR transmitter signals are stored, with which the UE can control devices in the living room as TV, video, etc ..

p0079Of course, the solution can be implemented as a PC card also place an external base box.

p0080Overall, the PC-based box component list consists of the following

p0081components:

p0082Board & housing & Assembly; 4 video connector (2 * S-VHS; 2 * composite);

p00832 Audio cable (stereo, cable, plug and double it ^;

p0084AV (audio / video) transmitter, optional nor an AV receiver;

p0085Encoder for data on audio and optionally a decoding rer audio in audio and data; external power supply;

p0086Data Interface: USB adapter cable, or Com2 cable or printer port cable

p0087Altogether, the following components are necessary in the TV center box:

p0088A maximum of three switches controlled via I2C;

p0089Possibly a remote control (with the same IR code as

p0090Standard TV card);

p0091IR power transmitting diodes; 1 Pic controller for data communication; external power supply;

p00922 SCART sockets, 1 Scart plug; IR receiver and amplifier; Built-in microphone;

p0093Microphone switch with on / off switch evtl.- LED; the switch is necessary to intrude the microphone output to the TV audio output settings after (unless a mixed mode is desired, such as a video post) the TV is muted; 12.5 volt switching voltage generator.

p0094The web pad itself has no CPU, no memory, no hard drive and no PC-type hardware. It consists of cheap AV components:

p0095A AV receiver and an optional AV transmitter (eg webcams or connecting a VCR to AV Interface);

p0096An AV (AV input and AV out);

p0097A touchscreen with composite input (optional VGA input converter or transmission of VGA in the AV-route); Optional IR transmitter and receiver;

p0098to data given in a data transmitter and a receiver or optional encoder / decoder of the audio stream or interfere there.

p0099The aforementioned basic disadvantages of PC-based pads are bypassed by the arrangement and subcomponents of the proposed solution.

p0100On a standard PC, the portable remote PC pad is connected to the usual IO ports, preferably on the RS232 interface, as well as USB or Bidirectional LPT Ports would be possible. The video and audio are A - and outputs connected to the PC-based box, as shown in Fig. 1. If the graphics card does not have a TV-out output, a VGA2PAL converter module is plugged into the PC base box and the VGA output connected to the VGA cable to the PC base box. The monitor is connected to the VGA-out output of the converter.

p0101The signal from the internal microphone of the Web pad directly into the microphone input of the PC.

p0102In principle, also connectable would be a camera that is also switched to the video output signal of the optional AV transmitter. Thus, bidirectional video telephony would allow. Without an own camera monodirek- tional video telephony is already feasible. The Pad-owner sees caller who has a webcam.

p0103A joystick would preferably be connected to the Web Pad. The control commands would also be implemented, such as the mouse commands, the integrated mouse simulation of a touch screen.

p0104By installing a TV tuner card in your PC the Padbenutzer are all the advantages of a TV card. Mix mode with PC / Internet; Show text, Picture in Picure mode; Multichannel preview (eg 16 channels view simultaneously on one screen); Recording of the program on the hard disk; Save images. In particular EPGs now be used, which are updated on the Internet and can actively support the user directly with program selection: Independent Switch the TV program through the PC software, Hiding unwanted broadcast content (advertising or child protection); Recording on video recorders or hard disk; Show incoming mails or phone calls; Interactive television by overlaying menu interfaces with the TV picture; Round-the move to PC Desktop and familiar control via mouse and keyboard etc .. That is, computer-based television without having to sit at the computer.

p0105However, the solution presented not only allows the import of this "personal TV" called virtual channel but can control located in the living room devices via infrared. The PC were once taught the appropriate IR sequences on the Learn-diode of the pads and stored on the hard disk. In addition, has been configured, the order in which these signals must be sent to the terminal, so as the set changes in two-channel mode. After the PC via pad can control all devices by sending IR commands.

p0106Even child protection requirements can be implemented so as the PC can prevent viewing unwanted channels and via EPG even program-related.
