Malaysia

TV3 of Malaysia introduced DOGs to Malaysian television in 1995, and 1997 for RTM (although DOGs has been partially used starting in 1991). Malaysian TV logos are in full-color, the logos are removed during commercial breaks, trade test transmissions and transitions between programs.

, in which the logo is shown in the top left.

Poland

Polish television introduced the logos in 1992 because TP was rebranded to TVP. At that time, TVP was the only broadcaster in Poland with two channels: TVP1 and TVP2. The DOGs of TVP are white, while the PolSat one was in full-color until 1994, local TV broadcasters show the logo in full-color. Polish television removes the logo in commercials, trailers and other non-program broadcasts, except test cards. The TVP logo is always shown in the top right side of the screen.

Serbia

The Serbian national television RTS began showing logos in the early 1990s. Their logo was sometimes turned on manually during certain broadcasts but shortly afterwards remained permanently on-screen. One could notice how they were manually controlled, as the "logo-free" time during the begin of a program varied. Until around 1994–1995 their logos were opaque white and black, presumably due to being inserted into the analog CVBS signal just before being broadcast instead of an analog YUV, RGB or digital SDI signal, while in the mid-1990s they upgraded to colorized but still opaque logos. RTS's predecessor RTB (Radio Television of Belgrade) had DOGs of varying sizes, but rather than being introduced one after another they appear to have been used simultaneously at different broadcast sites. At least three different sizes and styles of their opaque black-and-white logo are known today. On the satellite channel "RTS-SAT", Latin letters were used, but after the destruction of RTS headquarters in 1999 during a NATO air strike, it could be noticed how the logo appeared to have been quickly re-drawn and was being inserted by different equipment as it varied in shape and size, presumably because of the original equipment used to insert it being destroyed. Today RTS has the same opaque color logo from 1999 on RTS-SAT and new translucent logos were introduced in the 2000s for the analog terrestrial programs. Old logos remain on most archived recordings presumably due to lack of a cleanfeed archiving policy in the past, as can be seen in the "Trezor" historical series: http://www.youtube.com/watch?v=UbLujWaoJl0

Trivia: During a football victory in 1990, the logo jumped from the left to the right corner and back many times, presumably due to a technician playing with the DOG inserter out of happiness over the victory. http://www.youtube.com/watch?v=dI7tkw09NnI

Most local and regional stations and some national commercial broadcasters (Pink, B92, Avala) in Serbia along with station logo also show a digital clock below the logo.

Singapore

Singaporean televisions began showing the logo during television programs in 1994. The television stations show the logo in full-color, and are usually shown in the top right of the screen. Like its neighbouring country, Malaysia, Singaporean channels remove logos during commercial breaks.

Thailand

Thai television started showing the DOGs in 1988, the first channel was TV3. The logos are removed in the commercials and test cards, and usually removed during the transition between programs. TV5 does not remove logo in the movie trailers. In 2000, TV3, TV5 and TV7 added the station's website URL to the logo, and later, in 2007, MCOT and ITV. ITV removed their website URL from the logo on 8 March 2007, when ITV rebranded to TITV, and show the website again in 2009, called TVThai. Thai television logos are in full-color, and usually the logo is in red, green and blue, with the channel name in the middle. TV5 used to show the current status above the logo in 3 colors, green means everything is normal, yellow means there will be something happening later, red means its in bad situation. The status was added in 26 December 2004 (tsunami) and was removed in 2006. In 2007, every channel showed the logo of the King's 80th birthday in the left of screen. Thai TV logos are usually shown in top right side of the screen, the top left side is for the clock, the bottom left side is for the program logo and the bottom right side is for hand language, but in rare cases, the logo is moved to the bottom right side. Logos, tickers, clocks are usually removed when in the royal news at 8pm.

Following the rebrand to "five" in 2002 the DOG disappeared until October 2008.

In its website FAQs, Five's stated reason for its use of a DOG is that "the vast majority of channels carry them, most permanently and virtually every channel at some point has one during the day." However, on 21 October 2008, the BBC announced that it was removing the DOG from BBC HD for all films and most dramas, acknowledging that there was an "irritation factor". However, the dog came back on the same day as when BBC One HD launched. More recent additions are graphics which appear near the end of a programme to tell the viewer what's up next, despite this information being available at a touch of a button on digital TV. Many viewers also find this practice annoying, distracting and unnecessary.

Therefore they nowadays frequently overlay their callsign on the signal instead of having a paper card in the background. Most hams use for this purpose homebuilt devices or old consumer character generators. Only rarely one can see real graphics, as most of the time their callsign is written out in the typical "OSD font".

Live DOGs by hobbyists

One of the easiest and most sought-after devices used to generate DOGs by hobbyists is the 1980s vintage Sony XVT-500 video superimposer. This device can luma-key a signal, capture a still frame into memory and then overlay the keyed graphic in one of eight colors onto any CVBS signal.
