Identical Blu-ray/DVD remote
Does a Blu-ray/DVD remote have to be the same as the other? 86.141.121.115 (talk) 19:45, 3 November 2022 (UTC)
 * The other what? ←Baseball Bugs What's up, Doc? carrots→ 20:25, 3 November 2022 (UTC)
 * Other remote. 86.141.121.115 (talk) 21:45, 3 November 2022 (UTC)
 * Still confused. Do you mean a remote for two different devices? Nil Einne (talk) 23:48, 3 November 2022 (UTC)
 * As far as I know any bluray player will also play DVDs so you don't need two devices. Now I don't know if that applies to 4K or 3D players so other editors can correct me if I'm wrong. MarnetteD&#124;Talk 00:35, 4 November 2022 (UTC)
 * Yes but can have two different Bluray players or two different DVD players or a Bluray and a DVD player which might be what the OP is referring to but it is totally unclear. NB I should have said the remotes above. Nil Einne (talk) 06:15, 4 November 2022 (UTC)
 * I mean the same Blu-ray/DVD remote. 86.141.121.115 (talk) 21:37, 4 November 2022 (UTC)
 * So do you mean, "Do all Blu-ray/DVD remotes have to be the same?"? --Lambiam 08:34, 4 November 2022 (UTC)
 * Yes. 86.141.121.115 (talk) 21:38, 4 November 2022 (UTC)
 * It’s actually an interesting question. Theoretically, according to the literature, it should work, assuming the IR frequency is the same. Viriditas (talk) 08:44, 4 November 2022 (UTC)
 * What is the "it" that should work according to the literature? Using the remote for one DVD player to control a different Blu-ray player responding to the same frequency? --Lambiam 11:48, 4 November 2022 (UTC)
 * Yes. :-) Viriditas (talk) 20:37, 4 November 2022 (UTC)
 * If you mean do you meed to replace your old remote control with a similar one, yes. It must be designed for that model. You might get away with a different remote from the same manufacturer, or a so called universal remote, but it may have some features missing. Shantavira|feed me 11:48, 4 November 2022 (UTC)
 * Are you asking whether the physical design of the remote has to be the same, or are you asking about some other feature of the remotes? MtPenguinMonster (talk) 11:53, 4 November 2022 (UTC)
 * I'm asking if the physical design of the remote has to be the same. 86.141.121.115 (talk) 21:39, 4 November 2022 (UTC)
 * My understanding is that you have only two choices: you can use another identical remote from an identical player, or you can use a universal remote. Viriditas (talk) 21:45, 4 November 2022 (UTC)
 * So does my Blu-ray/DVD remote have to be identical? 5.80.15.114 (talk) 20:11, 5 November 2022 (UTC)
 * It will depend on the manufacturer(s). ←Baseball Bugs What's up, Doc? carrots→ 21:44, 5 November 2022 (UTC)
 * Yes Baseball Bugs is right. While I don't have that much experience with Bluray or DVD player remotes, with TV remotes I do know manufacturers sometimes preserve at least some of the IR codes while redesigning the remote's physical look. You can probably confirm this looking online at LIRC codes or similar. In other words, the remote may not have to be identical to work although it will generally have to be for the same brand and type of device. IIRC in the past, some VCR remotes had a few buttons to control the TV from the same manufacturer, I don't know if this ever happened with DVD or Bluray players and more importantly I'm even more skeptical it happened in the reverse. (I.E. even if there were player remotes with keys to control a TV, I still doubt there were original manufacturer TV remotes with codes to control players. Universal remotes etc are a different story.) Note with HDMI CEC, it's theoretically possible to control a Bluray or DVD player via a TV or some other device connected to the player with HDMI but to be clear the remote codes are still be understood by the TV or whatever and passed to the player. Also it's likely commodified nature of the player market has affected things in some way. (Where manufacturers generally keep models for ages and design etc may be partly or complete outsourced.)

 * See also RC-5 but it doesn't even have info on DVD players let alone Bluray ones. Nil Einne (talk) 03:33, 6 November 2022 (UTC)


 * Sorry, I'm still stuck on what the OP is actually asking. Your Blu-Ray player will play DVDs. You don't need two devices or two remotes; you just need the BD player and its remote control. If you have two devices for some reason, the remotes almost certainly won't work across devices. Matt Deres (talk) 16:59, 8 November 2022 (UTC)
