A 100HZ TELEVISION In a known arrangement, the frame rate of a television signal is doubled by using a field store. In a first operating mode, each field of the television signal is entered into the field store in this arrangement and read out twice at twice the frequency. In a second mode, only every second field is entered into the field store and read out four times at twice the frequency. In an arrangement for converting an original picture signal representing a sequence of frames, each of which is composed of two interlaced fields, into a converted picture signal which has a double field frequency with respect to the original picture signal, is for doubling the field frequency, for the purpose of noise reduction, motion compensation and line flicker reduction.
100Hz digital scan,To improve the picture quality in a television receiver which displays the received television signal in accordance with the line interlace method, frame stores are increasingly used. The remaining system-related flicker disturbances caused by the line interlace method require different signal processing for stationary and moving frame sequences in known flicker reduction processes, in which the receiver switches from flicker-free to motion-correct 100-Hz field repetition rate even with a relatively slight movement. To reduce system-related line flicker disturbances with line interlace reproduction, the signals contained in the frame store are in each case divided by vertical filtering in the television receiver into a vertical high-frequency and low-frequency signal as determined by the position frequency, these signals are differently processed in dependence on movement and the processed high-frequency and low-frequency signals are reproduced with twice the vertical frequency in line interlace. The flicker reduction method according to the invention can be used in all television receivers in which the television signal is reproduced at twice the vertical frequency in line interlace,
It has 2 AV SCART Connectors, Digital Audio , Front bottom 8 digit led displays (last time seen), RCA AV connectors, SVHS jack Multistandard capability, SVM (Scan velocity modulation.), many other features.
A SCART Connector (which stands for Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a standard for connecting audio-visual equipment together. The official standard for SCART is CENELEC document number EN 50049-1. SCART is also known as Péritel (especially in France) and Euroconnector but the name SCART will be used exclusively herein. The standard defines a 21-pin connector (herein after a SCART connector) for carrying analog television signals. Various pieces of equipment may be connected by cables having a plug fitting the SCART connectors. Television apparatuses commonly include one or more SCART connectors.Although a SCART connector is bidirectional, the present invention is concerned with the use of a SCART connector as an input connector for receiving signals into a television apparatus. A SCART connector can receive input television signals either in an RGB format in which the red, green and blue signals are received on Pins 15, 11 and 7, respectively, or alternatively in an S-Video format in which the luminance (Y) and chroma (C) signals are received on Pins 20 and 15. As a result of the common usage of Pin 15 in accordance with the SCART standard, a SCART connector cannot receive input television signals in an RGB format and in an S-Video format at the same time.Consequently many commercially available television apparatuses include a separate SCART connectors each dedicated to receive input television signals in one of an RGB format and an S-Video format. This limits the functionality of the SCART connectors. In practical terms, the number of SCART connectors which can be provided on a television apparatus is limited by cost and space considerations. However, different users wish the input a wide range of different combinations of formats of television signals, depending on the equipment they personally own and use. However, the provision of SCART connectors dedicated to input television signals in one of an RGB format and an S-Video format limits the overall connectivity of the television apparatus. Furthermore, for many users the different RGB format and S-Video format are confusing. Some users may not understand or may mistake the format of a television signal being supplied on a given cable from a given piece of equipment. This can result in the supply of input television signals of an inappropriate format for the SCART connector concerned.This kind of connector is todays obsoleted !
TV signals are defined primarily the National Television Standards Committee (NTSC), the Phase Alternative Line (PAL) or the Sequential Couleur Avec Memoire (SECAM) systems, and used in different countries around the world. An analog TV signal utilizes mainly two or three RF carriers, combined in the same channel band. One carrier may commonly be amplitude modulated (AM) with video content, and the other may be frequency modulated (FM) and/or amplitude modulated (AM) with audio content. An analog TV receiver functions by performing a series of operations comprising adjusting the signal power, separating the video and audio carriers, and locking to each carrier in order to down-convert the signals to baseband. The baseband video signal may then be decoded and displayed by achieving horizontal and vertical synchronization and extracting the luminance and color information. After demodulating the received signal, the resulting baseband audio may be decoded, and left, right, surround channels and/or other information may be extracted.- The METZ 70TH73 NORDKAP-70S Features a multistandard PAL/SECAM/NTSC 3.58 & 4.43 CCIR B/G/H/I/L/D/K/M. The different coding processes, e.g. NTSC, PAL and SECAM, introduced into the known colour television standards, differ in the nature of the chrominance transmission and in particular the different systems make use of different colour subcarrier frequencies and different line frequencies.
The following explanations relate to the PAL and NTSC systems, but correspondingly apply to video signals of other standards and non-standardized signals.
The colour subcarrier frequency (fsc) of a PAL system and a NTSC system is fsc(NTSC) = 3.58 MHz or fsc(PAL) = 4.43 MHz.
In addition, in PAL and NTSC systems the relationships of the colour subcarrier frequency (fsc) to the line frequency (fh) are given by fsc(NTSC) = 227.50 * fh or 4•fsc(NTSC) = 910 • fh fsc(PAL) = 283.75 * fh or 4•fsc(PAL) = 1135 • fh so that the phase of the colour subcarrier in the case of NTSC is changed by 180°/line and in PAL by 270°/line.
The invention relates to a digital multistandard decoder for video signals and to a method for decoding video signals. Colour video signals, so-called composite video, blanking and sync signals (CVBS) (chroma-video-blanking-sync) signal is a signal comprising both the chrominance and the luminance component of the video signal. Therefore, the CVBS video signal may be PAL video signal, a SECAM video signal, or an NTSC video signal. are essentially composed of a brightness signal or luminance component (Y), two colour difference signals or chrominance components (U, V or I, Q), vertical and horizontal sync signals (VS, HS) and a blanking signal (BL).
In order to decode a video signal and restore a color image, a color TV set has to identify the color TV standard used at the emission. Conventional color TV sets are equipped with a system for automatically identifying the norm or standard of the color TV set used for the emission. The invention more particularly relates to an automatic method for identifying a color TV standard in a multistandard TV set.
Presently, the most commonly used color TV standards are PAL, NTSC and SECAM standards. For these three standards, each line of the composite video signal comprises a synchronization pulse, a burst of a few oscillations of the chrominance sub-carrier signal, then the signal itself corresponding to the image, comprising superimposed luminance and chrominance information, the latter information being carried by the luminance signal.
The characteristics of the chrominance sub-carrier in the various PAL, NTSC and SECAM standards are defined in the published documents concerning these standards and will not be described in detail here. However, the main characteristics of these various standards will be briefly reminded because these indications are useful for a better understanding of the invention.
In the PAL standard, the frequency of the chrominance sub-carrier is equal for all the lines, but the phase of one of the modulation vectors varies + or -90° from one line to another. The frequency of the chrominance sub-carrier is standardized at 4.43 Mhz. In this system, the burst signal is also shifted by + or -90° from one line to the next.
In the NTSC standard, the chrominance sub-carrier is equal for all the lines.
In the SECAM standard, one uses two chrominance sub-carrier frequencies which alternate from one line to another, at 4.25 Mhz and 4.40 Mhz, respectively. These two chrominance sub-carriers are frequency modulated.
The multistandard color TV sets must have distinct internal systems designed to decode the luminance and chrominance signals for each standard used.
Therefore, these TV sets have to previously identify the received standard.
Systems for automatically identifying the standard used already exist. Generally, for such an automatic standard identification, the systems known use the bursts of the chrominance sub-carrier signal that are present at the beginning of each line. In fact, these bursts are standardized and calibrated samples of the chrominance sub-carrier transmitted on the video signal and comprise all the characteristic information concerning the transmitted color standard. The information contained in these bursts represents the frequency, the phase of one of the modulation vectors and the frequency or phase variation of one line with repect to the next one.
- CTI Picture Improvements circuitry in which colour signal, e.g. the line-sequential colour difference signals (R-Y,B-Y), is processed by an edge steepening circuit e.g. a colour transient improver and/or a two-line delay line in which the colour signals from two lines are added. The delay line may be part of a drop-out compensation circuit in which the colour signal of line n is replaced by the signal present for line n-2. A CCD-line may be used as the two-line delay line, and an amplitude limiter included. ADVANTAGE - Increased picture sharpness and improved signal-to-noise ratio.

Metz: 70 Years’ of "made in Germany" quality
Customer-oriented and successful
Back to the future
Metz was founded back in 1938. From this point in time, Paul Metz managed his company with untiring effort, always introducing new ideas to steadily grow the business. In 1947 he began producing radio sets. He expanded to other fields in the following years. And to this day Metz stands its ground successfully in the entertainment electronics, photo electronics and plastics technology sectors.
Photo electronics: Metz flashguns attain world fame
In 1952, Paul Metz went in into the flashgun business and began marketing an emblematic trend-setting innovation in 1979 with the introduction of the worldwide single SCA adapter system which made it possible to attach Metz flashguns to cameras of all well-known brands and went on to establish Metz as one of the leading worldwide brands in this area. Since then, Metz flashguns have been exported to over 90 countries. The latest successful model was voted "the best flash unit in Europe" at the end of 2007. It was the world’s first flash to be equipped with a USB interface. The individual firmware for every version of the model can be easily updated via computer and internet by means of this interface.
