Random information on the term “Chum”:

CHUM Limited was a Canadian media company based in Toronto, Ontario in operation from 1945 to 2007. The company was founded in 1945 as York Broadcasters Limited when it launched CHUM-AM 1050 but was acquired by salesman Allan Waters in 1954. CHUM had expanded to and owned 33 radio stations across Canada under its CHUM Radio Network division (now Bell Media Radio) and also owned other radio stations.

The company also operated full or joint control of 15 local television stations under the ATV, Citytv (acquired in 1981) and A-Channel (formerly NewNet, now CTV 2) brands, one CBC Television affiliate, one provincial educational channel, Atlantic Satellite Network in Atlantic Canada, and 20 branded specialty television channels, most notably MuchMusic and its various spin-offs that were launched under Moses Znaimer, the co-founder of CITY-TV, targeting younger audiences.

In July 2006, one year after the death of Waters, CHUM agreed to merge with CTVglobemedia (now Bell Media), owner of the CTV Television Network. The merger was completed on June 22, 2007; regulatory approval was made conditional on the sale of CHUM’s five Citytv stations to Rogers Communications. The company itself was renamed CTV Limited (now CTV Inc.) and continues as a subsidiary of Bell Media. Its Toronto radio stations TSN RADIO 1050 and CHUM 104.5 continue to use “CHUM” as their call signs. The headquarters were located at 299 Queen Street West in Toronto, the famous CHUM-City Building, which currently serves as Bell Media’s headquarters.

Random information on the term “PAL”:

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. It’s usually associated with CCIR System G for UHF broadcasts.

It is mostly replaced across Western Europe, part of Asia and Africa by digital broadcasting.

The system was developed for VHF (also known as VHF-3) band (part of RF band lower than 300 MHz.) Some of the most important specs are listed below.

A frame is the total picture. The frame rate is the number of pictures displayed in one second. But each frame is actually scanned twice interleaving odd and even lines. Each scan is known as a field (odd and even fields.) So field rate is twice the frame rate. In each frame there are 625 lines (or 312.5 lines in a field.) So line rate (line frequency) is 625 times the frame frequency or 625•25=15625 Hz.

The video bandwidth is 5.0 MHz. The video signal modulates the carrier by amplitude modulation. But a portion of the lower side band is suppressed. This technique is known as vestigial side band modulation (AC3). The polarity of modulation is negative, meaning that an increase in the instantaneous brightness of the video signal results in a decrease in RF power and vice versa. Specifically, the sync pulses (being “blacker than black”) result in maximum power from the transmitter.
