content: The "channel" on a TV can have two different meanings. It can mean the UHF transmission channel (frequency), or it can mean the programming channel (e.g. NBC).It is possible for two different local TV stations to broadcast the same programming on different UHF channels from different antennas. When this occurs, the commercials are likely to be chosen by the local TV station and not by the remote network program source (this is how your local TV station can give you commercials for businesses in your local city and not some city on the other side of the country).So...if you had two different TVs tuned into two different local TV stations from different broadcast antennas, but both showing the same programming, then you would likely see different commercials. How this might happen in practice is one TV might be using a directional antenna on the roof, and the other TV might be using a set top antenna pointing in a different direction.

content: If you have cable or satellite and a set top box, the company will put commercials on that are aimed at your demographic. So if you are watching with one tv on a cable box, and another tv without a cable box, you will likely to see some different commercials. Targeted tv ads are a big industry.

content: Quote from: FennecTECH on November 13, 2014, 08:07:53 pmIf both TVs were tuned into the same frequency they would be receiving the same signal and would be showing exactly the same picture. Therefore if each TV was showing a different picture at the same time during commercials, they were of necessity tuned into different frequencies and receiving different broadcast channels. There is no other possibility.

content: Where I live we get TV from 2 different countries, I have line of sight to 2 transmitters,So we should get Wales TV, but I can also pick up a transmitter in England. Old analogue TV's this was no issue as everyone knew the frequency range for the appropriate transmitter.But with Digital TV most TV's auto tune the multiplexes and some TV's in our house will show news, adverts and weather for England and some for Wales.It's a pain in the bum, so I have a linux satellite receiver instead now

content: How few years back? was one TV on an analog broadcast station and the other a newer TV on the same digital broadcast that could have different commercials for whatever reason?

content: did you check to see if one of the TVs had a flux capacitor in it, and that TV was just running a re-run tv show? If that was the case, you were watching a re-run of the same tv show, but that TV was broadcasting from the future, which would make sense as to why the commercials were different.

content: I'm a Telecommunications Expertif you claim that you had 2 Analogue Television setsin the same houseconnected to the same TV AntennaTuned to the same Frequencyand on the Same PHYSICAL CHANNEL (not TV channel)and after all that, you claim that you saw 2 Different commercialSorry... Not PossibleEven if it was some Government conspiracy........... not possible(FYI, I'm in Australia)but, regardless of where you are in the Worldyes we have Modulation Differences and Bandwidth Differencesbut.. fundamentallyif you are on a certain Frequencylet me use Examples in australia. oklet's say (i'm in Sydney) and my Antenna is Pointing towards North Sydney (Artarmon Transmitter)and i want to watch TV Channel 7 (digital 7)so, that's on the Frequency of 117.500 MHz (if i'm not mistaken)and on my spectrum Analyzer (and according to the Australian Channel Plan)this Frequency is PHYSICAL CHANNEL 6Physical Channel Numbers are not the same as TV Channel NumbersEg.this frequency that's onPhysical Channel 6has about 7 Shows Broadcasting at the same time (Multicasting)now when you tune in your TVlet's just use 3 of the broadcasts on that 1 frequency as an examplelet's takeDIGITAL 7DIGITAL 7 TWOGEMso..DIGITAL 7 Scans in on TV Channel 70DIGITAL 7 TWO Scans in on TV Channel 72GEM scans in on TV Channel 73but. they are all on 1 Frequencybut.. that's digitalyou said you had an analogue TVso, that TV Must have an Analogue RF Tuner (Assuming no Set Top boxes are connected to it )so, if your one 1 Analogue Channel (PHYSICAL CHANNEL) or Digital.. it doesn't matterand you scan in your 2 TV'syour 2 TV's are connected to the same AntennaTherefore the signal that comes in on one will come in on the otherand your part of the world will have a CHANNEL PLAN FOR THE COUNTRYYour TV's When manufactured, WILL HAVE TO CONFORM TO THAT PLANso.. it's impossible for you to receive 2 different broadcasts on 2 different TVs in the same premisesHere are some possible scenario's that give logic to what your saying- Maybe 1 TV was connected to 1 Antenna Pointing in a certain Directionand the 2nd TV was connected to a different Antenna pointing in another directionHence your receiving 2 different broadcast signals- Maybe you had the 2 TV's on different TV Channels , but you didn't realize it (it happens)- Maybe you had both TV's on the same antenna, but.. one of them was connected let's say TV Channel 2 and watching LIVE TV Channel 2and the other had a Video Player connected with a Tape in it, and the Video Player was tuned to run off TV Channel 2and then somone presses PLAY on the video and Vuolayou think your watching 2 different broadcastswell, actually you are.... But they are not both live broadcasts that could also happenbut the bottom line isthere is no way under god, Not even remotely possiblethatif you have 2 TV'sconnected to the same antennaTuned to one Transmitterand the TV's are on the same Physical Channelthere is no way , absolutely no way at all to view 2 Seperate programsEven ifthe broadcaster wanted to play a birthday prank to scare the shit out you on your birthday and spend millions of dollars doing it.IT'S STILL ON THE SAME PHYSICAL FREQUENCYI don't say this word oftenbut...that scenario is Simply "IMPOSSIBLE"Even if your entire country, Changed it's channel plan for 10mins (which would never happen)you would still be on a New Frequency, but both TV's would be on that same frequencyit's not possiblesomething happened that you didn't realize was happeningVideo TapeDifferent Channelextra AntennaSatellite TVCable TVsomething else was being transmitted on the second TVthat's the only explanationas to what and howi'm not there , i don't knowif i was, i would knowbut, there was a 2nd Broadcast signal of some naturethat's how it happens
