Talk:Simultaneous substitution

message: I live in Quebec city Canada and I can say that there's no simultaneous substitution with CTV's feed. I don't know if there's any sort of infringement made by CTV, but at least here in Quebec city the substitution thing is not an issue. For the first time in a long time people will be able to watch the ads of the superbowl this year without CTV's substitution feed.VincentG (talk) 03:26, 9 January 2008 (UTC)
thread_title:  Simulcast on CTV 

message: This can't go on any page because it is deemed "original research", but all signals for our Vancouver Shaw HD service (including ABC and FOX) are now exclusively 1080i. This will cause problems with re-compression from 720p to 1080i but it makes it a lot easier to simsub the channels. (Too bad there's no east coast channels to simsub, so all east coast signals are pure, but still converted to 1080i) I reached this when I saw and said "Why is the raw stream of ABC and FOX 1080i? It's supposed to be 720p..." --Jack Zhang (talk) 20:09, 25 October 2008 (UTC)
replies: text: Whenever a show is broadcast in 1080i on a major US network (CBS and NBC), and a Canadian network is hijacking but is broadcasting only at 720p, the resulting hijacked feed will be only 921,600 pixels, while a 1080i signal is 1,382,400 pixels, a difference of 460, 800 pixels!  This is an inferior feed then, and the CRTC cannot view the picture being of equal or better quality, so the simsub shouldn't happen!  —Preceding unsigned comment added by 192.237.29.125 (talk) 17:03, 7 January 2009 (UTC)
replies: text: The feed is up-converted to 1080i from 720p, not the opposite, so it's legal, yet still it recompresses the feed. But, the horizontal resolution will decrease from 720 to 540. --Jack Zhang (talk) 23:38, 1 February 2009 (UTC)
replies: text: Oh, I see that Bell TV converts everything to 720p, and they simsub nationally. That is wrong. And Shaw and Star Choice convert everything into 1080i, you lose horizontal resolution doing that. --Jack Zhang (talk) 02:51, 2 February 2009 (UTC)
replies: text: I thought a 1080i signal is 1920 x 1080, meaning it has 1920 pixels of horizontal resolution (1920 vertical scan lines), and since each frame is interlaced and drawn 1/60th of a second, it has 540 pixels of vertical resolution (540 horizontal scan lines).  Likewise, a 720p signal has 1280 pixels of horizontal resolution (1280 vertical scan lines) and 720 pixels of vertical resolution (720 horizontal scan lines), so if you convert from 720p to 1080i, you actually gain horizontal resolution.  —Preceding unsigned comment added by 99.236.62.106 (talk) 00:47, 25 February 2009 (UTC)
replies: text: Vertical is the 1920, Horizontal is the 540 (or I meant to say, you lose horizontal scan line resolution). But since some BDUs convert everything to 1080i, it's possibly legal. But what Bell TV does by converting everything to 720p makes their simsubs wrong. --Jack Zhang (talk) 10:24, 26 February 2009 (UTC)
thread_title: Make channels 1080i only to be compatible with simsubs?

message: How about 4 big time butchered simsubs in the last two days:
February 8 - Global cuts off the end of the NCAA on CBS and shows the Simpsons while the PGA on CBS is delayed until 3:03 by CBS
February 8 - Sun TV hijacks the NBA on ABC and takes the HD feed and slaps it on the SD channel, resulting in black bars on the top and bottom.  Then at halftime, Sun TV loses the HD feed and shows the SD feed on the HD channel, and the HD reduced feed on the SD channel as well, resulting in black bars on the top and bottom, and double black bars on the sides - resulting in a picture about 1/2 the total screensize on a widescreen TV when viewing ABC SD.  Also, the sound was 2.0 throughout the entire telecast for the first simsubbed game (Celtics - Spurs).  The Lakers - Cavs game was unmolested on ABC and everything was fine.
February 8 - The Grammys on CBS had massive audio dropouts as a result of Global hijacking the feed. 
February 9 - Global interrupts FOX's 24 and shows commercials in the middle of the show!
:It'll only get worse as the Academy Awards this Sunday. Looks like CTV wants to carry all their major events live on both coasts to hijack all signals. All CTVglobemedia stations also say that "Due to federal regulations, we can't show the Super Bowl Ads" (it also applies to all CTV assets that aren't local news showing best of reels). What a load of BS, It's them pressuring those regulators to do it in the first place. That Sun TV thing might be only on Bell TV satellite, they're the worst when it comes to simsubs, all simsubbable programming is simsubbed from the uplink center. --Jack Zhang (talk) 09:38, 20 February 2009 (UTC)
replies: text: The nightmare is true again, The Acadamy Awards are simsubbed just like the Super Bowl in the OTA transmitter areas. And all programs will be done so like this moving forward. There goes another freedom. *insert explicit language here*. CTV is communism. --Jack Zhang (talk) 01:06, 23 February 2009 (UTC)
thread_title: Massive Butcherings

message: I am currently in the process of revamping the article. I have already made changes to the intro., which include more specific references to simsubbing as a uniquely Canadian practice. Although the similar practice of syndex occurs in the US, it is separate, and simsubbing is unique to Canada and the CRTC. I am still looking to revamp the body of the article, which has not yet been affected short of the removal of the "United States" section. Please feel free to comment here regarding any comments, suggestions, or otherwise. Thank you. — `CRAZY`(lN)`SANE` 11:35, 7 March 2009 (UTC)
replies: text: I think that the introduction should be very, very simple.  Something like "Simsubbing is the practice when a Canadian network is put overtop of an American network and the original American commercials are replaced, and parts of the original American broadcast are cut out, missed, and the endings ruined."
*Crazy, thanks for the note on my talk page; sorry I haven't been able to reply until now. I'll take a look through the page over the next few days and comment. (Initial thoughts are that it needs more references, as forums and blogs aren't suitable, and that there seems to be too much of a focus on complaints.) Cheers. --Ckatzchatspy 19:26, 9 March 2009 (UTC)
replies: text: I am working on some additions to the introduction to help make it more clear to the average reader as to what simultaneous substitution actually entails. It is difficult to make a good balance of wording it both professionally and casually. — CIS (talk  | stalk) 05:18, 13 September 2009 (UTC)

message: Simultaneous substitution is a fairly important topic in logic and syntax.
There should be a pointer to this, even if just to a stub.  —Preceding unsigned comment added by 81.154.115.57 (talk) 04:43, 28 October 2010 (UTC)
thread_title:  Math 

message: I actually consider this "simultaneous substitution" practice to be a violation of Canadian national sovereignty, as it gives me the impression that the master control for the Canadian television station is actually in the States. --  Denelson83  02:21, 4 February 2012 (UTC)
thread_title:  Imperialist overtones 

message: I have attempted to contribute additional information where Simsub does not apply, i.e., out of local time zone availability. It was reasonable for others to require cleanup for neutral point of view, but the revised material was removed anyway. Perhaps there are employees of Canadian television networks, or Friends of Canadian Broadcasting, that do not want truthful information about how Simsubbing can be avoided to get out. The article mentions examples of errors in Simsub implementation, and illegal Simsub by some companies, i.e., if Bell is simsubbing any programs carried by TSN and another station. It would seem reasonable to allow information about how to lawfully avoid technical problems that affect the shows we pay to watch.  70.71.9.74 (talk) 21:31, 28 September 2012 (UTC)
replies: text: The problem is that your contribution was both unsourced and was written as a statement of opinion about how to get around stuff rather than as a straight neutral summary of the facts.

thread_title:  Information about Simsub Exception repeatedly removed 

message: Problem one - The main article fails to explain in simple terms what it is about.
Problem two - This talk page is not for anything but helpful comments regarding the main article; not for personal opinions about the practice of simultaneous substitution.
Problem three - Please indent properly when responding to a comment. - KitchM (talk) 19:39, 20 October 2013 (UTC)

message: This section does not make sense.  If the American network is running the show past the end of the time slot, then that will be lost if the Canadian station is dropped in right on the hour, or the beginning minute or two of the next program is lost if the sim-sub commences only when the American station starts the program that the Canadian station is already running.
Scenario 1 - Sim-sub starts with the Canadian broadcast time
   8:00 to 9:00 - Program Alpha runs.  US network runs two minutes over.
   9:00 to 9:02 - US network finishes Alpha, while Beta is yet to start.  Canadian network is running program Beta.
   At 9:00, the end of Alpha disappears as Beta begins with the sim-sub from Canada
   At 10:00, the Canadian network ends broadcast of Beta, but Beta continues for two more minutes on American network.
Scenario 2 - Sim-sub starts with the American broadcast start
   8:00 to 9:00 - Program Alpha runs.  US network runs two minutes over.
   9:00 to 9:02 - US network finishes Alpha, while Beta is yet to start; Canadian network now running Beta.  Cable viewer still seeing US signal.
   9:02 to 10:00 - US network running Beta now.  Canadian network signal cut into American signal, causing a jump that starts program already in progress, so cable viewer misses the part already shown on the Canadian network.
Neither is particularly agreeable - the first scenario is favourable to the viewer of Beta, but unfavourable to the viewer of Alpha.
