High-resolution extension for DVD, SAT and VCR devices Description:

The invention relates to the installation of a special electronic circuit in a commercially available satellite receiver, DVD player or video recorder. This circuit is used to generate twice the number of lines / twice the refresh rate of a PAL, SECAM or NTSC signal, or to reproduce three-dimensional, stereoscopic PAL, SECAM or NTSC video signals in both real (genuine) and virtual (simulated) mode.

In conventional television images, the number of lines is limited to around 625 lines, which is sufficient for most viewers on a television. However, when displayed on televisions with a diagonal of more than 70 centimeters or when projected using a projector, the television lines become annoying. If a higher image quality is required, a so-called line doubler has to be connected externally between the devices.

The invention is therefore based on the object of integrating an image enhancement system directly into existing devices.

This is achieved by installing an input and output module in existing end devices (SAT/DVD/VCR). After installing the electronic circuit, the image quality is significantly improved. High-resolution images are output to the corresponding playback devices via a VGA socket. At the same time, this special circuit enables the playback of real as well as virtual 3D material. Commercially available LCD shutter glasses are required for this. The circuit also makes it possible to influence contrast, brightness, color saturation and sharpness.

An embodiment of the invention is shown in the drawing. The figure shows:

The terminal (A) consists of a standard device into whose housing the input/output module (B) is installed. The integrated circuit (E) doubles the original 625 television lines and outputs these to a VGA output socket (G) with now 1250 lines (progressive scan). In addition, it is possible to convert an input 50Hz 2D signal into a 100Hz 2D signal using an additional module (F). The input and output module processes the signals from the converted satellite receiver, DVD player or video recorder in the manner described above, as well as signals input externally via FBAS and S-Video sockets (C).
If virtual 3D or real 3D playback is required, the signal is also converted to a 100Hz signal. In addition, the LCD shutter glasses (H) connected via cable or infrared are synchronized with this 100Hz signal. The electronic circuit also makes it possible to shift the two partial images of the supplied television/video image horizontally against each other in virtual 3D mode. This gives the 2D video signals processed in this way a certain spatial depth when viewed with shutter glasses (H).

Alternatively, the original properties of the devices (A), e.g. inputs and outputs etc. (D) remain fully intact so that they can be used as usual.

Definition

1. Real (genuine) 3D: Video images that have already been recorded stereoscopically on the camera, with half-image A containing the image information for the left eye and half-image B containing the image information for the right eye. The spatial impression is created by viewing the image via LCD shutter glasses on a corresponding playback device (PC monitor, projector, etc.). For real 3D, you therefore need specially recorded film material.

2. Virtual (simulated) 3D: A normal (two-dimensional) video signal is processed electronically in such a way that a certain spatial impression can be perceived when viewed with LCD shutter glasses on a corresponding playback device (PC monitor, projector, ...). With virtual 3D, no specially recorded film material is necessary.

3. Progressive scan: doubling the image line while maintaining the refresh rate

Claims (1)

Electronic circuit, built into a commercially available satellite receiver, a commercially available DVD player or a commercially available video recorder (VHS, S-VHS, Video8, Hi8, digital recorder). The connection and integration of such a circuit with the devices mentioned is to be protected. The invention is characterized in that: 1. The video signal supplied by the satellite receiver, DVD player, video recorder is output by the built-in electronic circuit to a VGA connection with either double the number of lines (progressive scan) or double the refresh rate (100 Hz). 2. Real 3D material is converted into a 100 Hz signal, output to a VGA connection and at the same time a 100 Hz synchronous signal required for controlling shutter glasses is generated. 3. normal 2D material is converted into a 100 Hz signal, processed by partial image shifting and given a certain spatial depth as simulated 3D material using shutter glasses. This partial image shift can be changed variably. The special circuit also enables the regulation of contrast, brightness and image sharpness. The original properties of the converted devices are alternatively retained. 4. The protection claim shall apply both to the 50 Hz PAL/Secam version and to a 60 Hz NTSC version of the converted satellite receivers, DVD players and video recorders.
