Broadcast television is traditional methods of transmitting television signals. placeholder text

=Analog Television Systems=
During the 1st and 2nd generation of video game consoles, RF connection was the only way to connect a video game console to a TV. During the 3rd generation some consoles such as the NES had separate outputs for unmodulated signals and all consoles had the option by the 4th generation. By the fifth generation, composite video became the standard form of connecting a video game console
;NTSC
:NTSC was the first color television system to be widely adopted ([[wikipedia:Field-sequential color system|a rival system]] had been developed that used field sequential transmission of color, but it was never put in wide use due to the lack of compatibility with existing sets). NTSC works by transmitting a high frequency color signal on top of the legacy black and white image, the amplitude of this signal determines the saturation while the phase determines hue, this is a property that many early consoles and home computers took advantage of. Every nation using the NTSC system also used a 59.94hz field rate. Many [[NTSC filters|filters]] are available for players wanting their games to look like they're played on an NTSC display.
;PAL
:PAL was created in Germany as a response to NTSC's susceptibility to hue fluctuations during poor reception conditions. The difference from NTSC is that the phase is inverted every other line, causing phase errors to cancel out, causing a less objectionable drop in saturation instead. The color signal is also in a higher frequency than NTSC, thanks to the larger channel bandwidth on European channel allocations. PAL was almost always used with a 50hz field rate.
;PAL-M
:PAL-M was only used in Brazil and should not be confused with PAL-60. PAL-M uses PAL encoding on NTSC channel allocations, as such the frequency of the color signal is lower than that of regular PAL, close but not the same as NTSC. As with NTSC PAL-M used a 59.94hz field rate.
;SECAM
:SECAM was developed in France for similar reasons as PAL. Unlike NTSC and PAL, which transmits a full color signal each line, SECAM alternates between two axes of the color signal, making a delay line mandatory for decoding. Also unlike NTSC and PAL this signal is frequency modulated, which makes it more robust to transmission errors. Aside from France, SECAM was used by the Soviet Union and its satellite states. For this reason SECAM is rarely found on video game consoles, most often opting to use a RGB SCART cable instead.
;MUSE
:MUSE was created in Japan in the eighties where it was used for HDTV transmissions as well as laserdisc. MUSE works in a completely different manner from the above systems and was never used for any video game console, and is only mentioned here as it was still an analog system :)

;MyRetroTVs
:This website is for watching captured footage from broadcast TV channels or various videos from the eras of the '50s to '00s, eliminates the need for handpicking videos and creating a personal collection, which can be time-consuming and require a significant amount of storage space. This website simply gathers videos from specific sources such as YouTube playlists etc, so we can say that this website offers a simulated experience of watching TV channels from during those specific eras, similar to what you might have seen on [[Wikipedia:Broadcast television systems|broadcast television systems]]. It also supports some basic [[#Enhancements]]. While this is a great way to experience retro television, there's room for even deeper immersion. For example adding surfing channel collections playlists, this could be achieved by integrating with Archive.org's vast collection of VHS TV channel surfing captures. Also integration with [[Virtual_reality#VR_game_room_simulations|EmuVR]], perhaps with some kind of support for playlists support for libretro core, could be a great next step too.
