CCIR System B (originally known as the “Gerber Standard”) was the 625-line VHF analog broadcast television system which at its peak was the system used in most countries.
What is TV system M?
CCIR System M, sometimes called 525 line or monochrome NTSC, is the analog broadcast television system approved by the FCC (upon recommendation by the National Television Systems Committee – NTSC) for use in the United States since July 1, 1941, replacing the 441-line TV system introduced in 1938.
What is NTSC M?
NTSC color encoding is used with the System M television signal, which consists of 30⁄1.001 (approximately 29.97) interlaced frames of video per second. Each frame is composed of two fields, each consisting of 262.5 scan lines, for a total of 525 scan lines.

What is CCIR video format?
CCIR System I is an analogue broadcast television system. It was first used in the Republic of Ireland starting in 1962 as the 625-line broadcasting standard to be used on VHF Band I and Band III, sharing Band III with 405-line System A signals radiated in the north and east of the country.
Why is VSB used in television?
A guard band of very small width is laid on either side of VSB in order to avoid the interferences. This VSB modulation is mostly used in television transmissions. The transmission bandwidth of VSB modulated wave will be the total of message bandwidth and the width of vestigial sideband.

What is CCIR standards for digital audio?
CCIR Standards for Digital Video The CCIR 601 (NTSC) data rate is ~165 Mbps. Uses NTSC frame rate, and half the active lines of PAL signals –> To play on existing TVs, PAL systems need to do frame rate conversion, and NTSC systems need to do line-number conversion.
What is VSB communication?
Vestigial sideband (VSB) is a type of amplitude modulation ( AM ) technique (sometimes called VSB-AM ) that encodes data by varying the amplitude of a single carrier frequency .
