PAL
PAL technology is a color coding system in television systems in large parts of the world in action. Other common standards, including NTSC and SECAM. PAL is an analog transmission and is a standard used alternately in all 625 lines. It is based on the frequency of 50 Hz line cycle used and administered in countries where it is often standard equipment in the stream.
PAL was introduced as a standard in 1967 and hasEight different - PAL B, PAL G, H PAL, PAL D, PAL I, PAL-K, PAL-K, PAL-N, PAL M. These branches of PAL have different specifications. PAL is used in China, India, Indonesia, Israel, Laos, Nepal, Pakistan, Thailand, Lebanon, Iraq, Iran and Britain, some European countries, some countries in South America and Africa.
Within Europe, France, along with some of its neighbors, SECAM-use technology, where, how, the rest of Europe uses the PAL standard. It is the dominantStandard in the world with the United States and Japan using the NTSC standard. 625 lines of PAL at 50 frames per second and a half working at 50Hz cycle.
NTSC
NTSC is the technology that sets the standard for television and video standard in the United States and offers a composite video signal with a refresh rate of 60 fields per second, interlaced. A framework consists of a data packet and in this case it would be a set of composite video signals, aFramework are contained. NTSC contains 525 lines and can contain 16 million colors. A mean composite video signal that includes all colors, like red, blue and green signals. It may also consist of audio signals for time. These are mixed to form the composite video signal.
NTSC is designed essentially a similar system in the United States and in use in Canada, Japan, South Korea, the Philippines, the United States and some other countries,especially in the North and South America. The refresh rate of 60Hz NTSC standard, and consists of 525 lines per image. Of these 525 lines, 485 carry the video information, the rest are sync pulses, which are not visible. The bank lines have been deliberately put there to allow time for electronic weapons in a television interview given to those who repositioned.
SECAM
SECAM is an analog color television for the first time in France, as a video standard, in the first half of 1960. It is historicallyEuropean first standard color television. SECAM uses the same bandwidth as PAL but transmits the color sequence. Operates at 625 lines per frame and uses the same frame rate as PAL, 25 frames per second. SECAM in France and former French colonies used. Also used in the former communist countries of Europe. Because of the same features that SECAM has with PAL, especially as regards the resolution and frame rate is concerned, using DVDs, VCDs and PAL SuperVHS internally, but before theSignal at the output is available, the color encoding to SECAM changed is displayed on a SECAM TV.
Because of incompatible video standards can not video tape of a region is seen on television of another country, a different standard. This means that a video tape are not considered in the United Kingdom to the United States. This video has no form of a videotape to convert PAL to NTSC for viewing. Multi-Video System can play, videotapes of allRules, but you can not become the default video standard compatible with the current television standard. Solution to this problem is a video recorder with the possibility of converting the output signal to a level compatible for viewing on a TV you have. This multi-system VCR should have an integrated converter for this purpose.
A basic system of multi video is not based on this processor and a separate converter needed to be used,between video and television, or you are a multi-system TV to view the tape. A multi-system TV also has built a converter, and all the VHS tape you can play the VCR to show in each of several base. To see, suppose you have a PAL video tape on a NTSC TV. You will not be able to see the movie, while your VCR is a multi-in and has an integrated converter. The PAL is read by tape recorder and NTSC video signals are converted when using the output of the VCRto the TV. If your multi-system VCR does not have a converter, you must have a multi-system TV set so you can see the tape. The other alternative would be to connect an external converter between your multi-video and NTSC TV when you can see the videotape.
When converting PAL to NTSC, the point is to remember that the standard NTSC video with a resolution of 720x480 and a speed of 30 frames per second, while PAL has a resolution of 720x576 with aFrame rate of 25 frames per second. Therefore, from the above specifications, which can be easily found that PAL has a better picture quality than NTSC, while NTSC has a better display of moving images due to the higher refresh rate.
TenLab TenLab offers converters, which is the conversion of one of video standards in the ability of others. These are independent of video-transmission standard converter that supports PAL, SECAM and NTSC. The converter equipment connects to the video output toconverter output goes to the TV signal input. So if you play a PAL video tape / disc on your multi-VCR / DVD, the converter output is a standard that is compatible with NTSC standard TV.
Some of the models TenLab stabilization of vision, with Bult-corrector in time and have a video enhancer to give a clear image quality and crisp. TenLab converters are also used by the number of companies. TheConverters are for professional applications such as satellite transmissions worldwide, MTV Latin America and Gulfstream Aerospace for the Board of multiple system entertainment systems.
TenLab was founded in 1988 with the mission to release the products in the incompatibility between different standards existing video systems worldwide to create. The company introduced the first NTSC video converter, works on standard video cassettes. SinceTenLab has continued to introduce new models and offered to improve the old to the new rules.
