You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 3.239.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 07:38, 2 November 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

((About|the infrared remote control protocol|the block cipher|RC5))
((Refimprove|date=November 2016))
((format|date=July 2014))

The '''RC-5''' protocol was developed by [[Philips]] in the early 1980s as a semi-proprietary [[consumer IR]] ([[infrared]]) remote control communication protocol for consumer electronics. It was subsequently adopted by most European manufacturers, as well as by many US manufacturers of specialty audio and video equipment. The other main protocol relevant to consumer electronics is the [[NEC]] protocol, which is largely used by Japanese manufacturers.

The RC-5 protocol, when properly implemented, has the advantage that any CD handset (for example) may be used to control any compatible brand of CD player. By comparison, the NEC protocol assigns each brand its own unique header(s) after which may follow any desired command set; this confers the advantage that there cannot be any interference between remote handsets for pieces of equipment made by different manufacturers.

==Protocol details==

The basics of the protocol are well known. The handset contains a keypad and a transmitter [[integrated circuit]] (IC) driving an IR [[LED]].<ref name="maxim">((cite web |publisher=Maxim Integrated |title=Infrared Remote Control System-on-Chip |url=https://datasheets.maximintegrated.com/en/ds/MAXQ617.pdf |access-date=2023-02-18))</ref> The command data is a [[Manchester code|Manchester-coded]] bitstream modulating a 36&nbsp;kHz carrier. (Often the carrier used is 38&nbsp;kHz or 40&nbsp;kHz, apparently due to misinformation about the actual protocol.)((clarify|date=September 2019)) The IR signal from the transmitter is detected by a specialized IC with an integral photo-diode, and is amplified, filtered, and demodulated so that the receiving device can act upon the received command.<ref>((cite web |url=https://www.vishay.com/docs/82491/tsop382.pdf |title=TSOP382xx, TSOP384xx IR Receiver Modules for Remote Control Systems |publisher=Vishay |type=Data sheet |access-date=2023-02-18))</ref> RC-5 only provides a one-way link, with information travelling from the handset to the receiving unit.

The command comprises 14 bits:

* A ''start bit'' which is always logic 1 and allows the receiving IC to set the proper gain.
* A ''field bit'' which denotes whether the command sent is in the lower field (logic 1 → 0 to 63 decimal) or the upper field (logic 0 → 64 to 127 decimal). Originally a second start bit, the field bit was added later by [[Philips]] when it was realized that 64 commands per device were insufficient. Many devices still use the original system.
* A ''control bit'' which toggles with each button press. This allows the receiving device to distinguish between two successive button presses (such as "1", "1" for "11") as opposed to the user simply holding down the button and the repeating commands being interrupted by a person walking by, for example.
* A five-bit ''system address'' that selects one of 32 possible systems.
* A six-bit ''command'' that (in conjunction with the field bit) represents one of the 128 possible RC-5 commands.

The 36&nbsp;kHz carrier frequency was chosen to render the system immune to interference from TV scan lines. Since the repetition of the 36&nbsp;kHz carrier is 27.778&nbsp;μs and the duty factor is 25 %, the carrier pulse duration is 6.944&nbsp;μs. Each bit of the RC-5 code word contains 32 carrier pulses, and an equal duration of silence, so the bit time is 64×27.778&nbsp;μs =&nbsp;1.778&nbsp;ms, and the 14 symbols (bits) of a complete RC-5 code word take 24.889&nbsp;ms to transmit. The code word is repeated every 113.778&nbsp;ms (4096 ÷ 36&nbsp;kHz) as long as a key remains pressed. (Again, please note that these timings are not strictly followed by all manufacturers, due to a lack of widespread distribution of accurate information on the RC-5 protocol.)

==System and command codes==

While the RC-5 protocol is well known and understood, what is not so well documented are the system number allocations and the actual RC-5 commands used for each system. The information provided below is the most complete and accurate information available at this time. It is from a printed document from Philips dated December 1992 that is unfortunately not available in electronic format (e.g., PDF), nor is an updated version available. This information is provided so that companies that wish to use the RC-5 protocol can use it properly, and avoid conflicts with other equipment that may or may not be using the correct system numbers and commands.

==Accuracy of information==

The information in the tables on this page is ''known'' to be accurate. Yet it is also clear that there are many gaps in these tables. For example, there is no category listing for DVD players in the system table. (They were not developed until five years after the date of publication of the material from which this information was obtained.) It would obviously be useful therefore to expand these tables with ''known'' accurate information. At this time, there are only a few possible ways to do so.

The first would be to capture the IR bitstream from the handset of newer Philips products, such as DVD players and analyze them to see what system number is used. The other would be to use the popular Philips Pronto series of programmable remote controls. These can be programmed to operate Philips components using the RC-5 protocol. Again, the bitstream output of the handset would need to be captured and analyzed. The only other way is to obtain the appropriate documents directly from Philips.

==System number recommendations==

As can be seen, this information is out of date. There are no longer any systems using CD-Video or CD-Photo, for example. In addition, many of the "Reserved" system numbers have no doubt been allocated by Philips during the intervening 16 years. In order to maintain compatibility, it would be helpful to obtain this information. Unfortunately, this has proven to be difficult.

When designing a product using the RC-5 protocol, the designer must follow the published information as closely as possible. For example, one surround-sound processor from a US specialty manufacturer used the system number 16, designated for "Preamp 1". This caused many problems with home theater installations that also included a separate two-channel preamplifier, which if of US or European origin, would also use the RC-5 protocol with system number 16. If the designers of the surround-sound processor had the correct information available to them, it would have been obvious that a better choice would have been to use system number 19, designated for "Preamp 2", as this would have avoided needless conflict between products.

==Command tables==

Over time, the information will also be added for the command tables so that all of the available information regarding the RC-5 protocol is gathered in one place. The information in the command tables shown in standard font was obtained from the Philips publication referenced at the bottom of this page. Information in ''italics'' is information that is ''known'' to be accurate, as it was derived by one of the methods described above.
