"Protocol" as used in this article seems to refer to both "data protocol" as well as modulation information. These terms should be identified and separated, as appropriate.

orphaned page resolution

I would suggest associating this page with "Remote Control". There is a link in "Remote Control" early in the entry for "Infrared" but it might make more sense to link to this article for Consumer IR, which can in turn lead to Infrared. —Preceding unsigned comment added by Ericnoel (talk • contribs) 18:37, 26 March 2008 (UTC)[reply]

carrier frequency

The article talks about e.g. 38kHz being the carrier, while I suspect this is baseband bandwidth,symbol rate or sampling rate. The carrier frequency is clearly the light signal, with much much higher frequencies (,e.g. 900nm wavelength). maybe someone can comment on this? — Preceding unsigned comment added by 129.132.209.62 (talk) 09:42, 20 June 2011 (UTC)[reply]

You are right when talking about the optical signal. Most of the article seems to talk about the electrical signal you gain/output when receiving/producing the optical signal. The optical signal is OOK'ed with the electrical carrier (at 38kHz), which in turn is modulated (again OOK) by the channel coded signal, which is produced from the codes. 81.221.146.60 (talk) 23:55, 6 July 2011 (UTC)[reply]

New remotes seem to provide higher bandwidth than 120bits/sec: LG ST600 TV Multimedia Upgrader

A new LG device, the ST600 TV Multimedia Upgrader, provides a scroll-feature on its remote, this is done using a infra-red scroll sensor. All Button press command are transmitted in old-style 32bit frames every 100ms on 38kHz carrier, but the scroll commands are transmitted in 26bit frames with a 20ms length and 10ms gap (3 times higher data rate) still on 38kHz carrier. They intermix these new coding with the old one (NEC protocol) and have extended the protocol by a new frame type with new bit coding. The new frame is indicated by a 1800us pulse followed by a 860us gap. The bit is a pulse of 500us with a gap of 360us for a "1" and a pulse of 220us with a gap of 360us for a "0".

The frame structure is <tttt> <ssss> 00 <xxxxxxxx> <yyyyyyyy> for cursor movements tttt = 1010 (type) ssss = the nibble (4-bit) checksum of the last 16 bits of this frame. xxxxxxxx = 8 bit x offset signed yyyyyyyy = 8 bit y offset signed

Original Research

I'm thinking about removing the statistics of carrier frequencies based from LIRC's files. That seems like orginal research to me and is generally unreliable anyways -- many of those files with lack of carrier information is in error and you can't assume 38Khz is correct. Anyone have any thoughts? --71.62.121.3 (talk) 16:44, 22 April 2012 (UTC)[reply]

Application examples for computers with "CIR" IR receiver

Can someone provide examples of the use of the CIR receiver that is seen on computers (IR remote products that come with their own receiver is excluded - that is propietry; and IRDA is excluded - its like a serial port and i have tested it), i have seen it but never been able to use it. If it is for a remote as this is article is implying, provide example programs that receive the information from the CIR device, and example computer products with CIR (some laptops from DELL for example) and example remotes you can buy to work with the CIR (as i have even seen CIR on desktops). On this computer it is called "ITECIR infrared receiver (EC)", when i use standard remote controls with a keycode assigning program does not pick up any keypresses.

Alternative technology

Hi,
The article has no mention of alternative technology. Can anyone write about that? Bluetooth, for example, is technically feasible. IR is cheaper than every potential competitor? Thx, ... PeterEasthope (talk) 00:25, 9 December 2023 (UTC)[reply]
