What is PAL and SECAM?
PAL is an abbreviation for Phase Alternate Line. This is the video format standard used in many European countries. A PAL picture is made up of 625 interlaced lines and is displayed at a rate of 25 frames per second. SECAM is an abbreviation for Sequential Color and Memory.
Which is best NTSC PAL or SECAM?

Why does Russia use SECAM?
Another explanation for the Eastern European adoption of SECAM, led by the Soviet Union, is that the Russians had extremely long distribution lines between broadcasting stations and transmitters. Long co-axial cables or microwave links can cause amplitude and phase variations, which do not affect SECAM signals.
Is SECAM analog or digital?
SECAM, also written SÉCAM (French pronunciation: [sekam], système électronique couleur avec mémoire, French for electronic color system with memory), is an analog color television system first used in France.

How do I know if my TV is NTSC or PAL?

Depending on the multinational bandplan for a given regional n, analog television channels are typically 6, 7, or 8 MHz in bandwidth, and therefore television channel frequencies vary as well.
Is SECAM compatible with the PAL video format?

What is the difference between SECAM and NTSC and PAL?
SECAM transmissions are more robust over longer distances than NTSC or PAL. However, owing to their FM nature, the color signal remains present, although at reduced amplitude, even in monochrome portions of the image, thus being subject to stronger cross color even though color crawl of the PAL type doesn’t exist.
Do long cables affect PAL and SECAM signals?
Long co-axial cables or microwave links can cause amplitude and phase variations, which do not affect SECAM signals. However, PAL and SECAM are just standards for the color sub carrier, used in conjunction with ITU television broadcast systems for the base monochrome signals, identified with letters such as M, B/G, D/K, and L.
What is the speed of a SECAM video recorder?
The VHS specification for “native” SECAM recording specifies that they be divided by 4 on recording to give sub carriers of approximately 1.1 MHz and 1.06 MHz, and multiplied by 4 on playback. A true dual-standard PAL and SECAM video recorder therefore requires two color processing circuits, adding to complexity and expense.
