33）X-Sat Protocol X-Sat Protocol
I call this the X-Sat protocol because it is used in the X-Sat CDTV 310 Satellite receiver made by the French company Xcom. This protocol is probably also used in other X-Sat receivers, but I have no means to verify that. I haven't seen this protocol anywhere else but that doesn't guarantee that it is unique to the X-Sat brand. Features
8 bit address and 8 bit command length Pulse distance modulation Carrier frequency of 38kHz Bit time of 1ms or 2ms Modulation
The X-Sat protocol uses pulse distance encoding of the bits. Each pulse is a 526祍long 38kHz carrier burst (about 20 cycles). A logical \1.0ms. The recommended carrier duty cycle is 1/4 or 1/3.
Protocol
The picture above shows a typical pulse train of the X-Sat protocol. With this protocol the LSB is transmitted first. In this case Address $59 and Command $35 is transmitted. A message is started by a 8ms AGC burst, which was used to set the gain of the earlier IR receivers. This AGC burst is then followed by a 4ms space, which is then followed by the Address and Command. A peculiar property of the X-Sat protocol is the 4ms gap between the address and the command. The total transmission time is variable because the bit times are variable.
An IR command is repeated 60ms for as long as the key on the remote is held down.
35
34）Philips RECS-80 Protocol 38kHz carrier
This protocol is designed by Philips and transmitters are produced by Philips (SAA3008) and ST (M3004). Personally I have never seen this protocol being used in real applications. All information on this page is derived from the data sheet of the Philips SAA3008 and the ST M3004 (10624.pdf).
There are 2 small differences between the two competitor ICs. The Philips IC has two modes of operation, one which is compatible with the ST chip and one which can handle up to 20 sub-system addresses. The ST chip has the capability of switching the modulation carrier off. Features
7 or 20 sub-system addresses, 64 commands per sub-system address 1 or 2 toggle bits to avoid key bounce Pulse distance modulation
Carrier frequency of 38kHz, or unmodulated
Bit time logic \
Command repetition rate 121.5ms (55296 periods of the main oscillator) Manufacturer Philips & ST Modulation 1/3 duty cycle
Normal Protocol
The drawing below shows a typical pulse train of a normal RECS-80 message. This example transmits command 36 to address 4.
Usually the first pulse is a reference pulse, with a value of \the exact bit length.
The next bit is a toggle bit. Its value is toggled whenever a key is released, which results in a different code every time a new key is pressed. This allows the receiver to discriminate between new key presses and key repetitions.
Only the ST chip M3004 can disable its carrier, in which case the REF pulse is interpreted as a second
36
toggle bit. The 2-bit toggle value is incremented every time a key is released. Thus only in this mode there is no real REF pulse.
The next 3 pulses S2 to S0 represent the sub-system address bits, sent with MSB first. This would allow for 8 different
sub-system
addresses
but both the SAA3008
and the M3004
can only generate
7
sub-system addresses in normal mode. Next come the 6 command bits F to A, also sent with MSB first allowing for 64 different commands per sub-system address.
The pulse train is terminated by a last pulse, otherwise there is no way to know the duration of bit A. The entire command is repeated (with unchanged toggle bits) for as long as the key is held down. The repetition rate is 121.5ms (55296 periods of the oscillator).
Address assignments are a bit odd with this protocol. You can not simply convert the binary value to a decimal
value. Below you see a table explaining
the relationship
between
the binary
and decimal
sub-system address values.
Extended Protocol
If you need more than 7 sub-system addresses you can use the extended protocol which allows 13 additional sub-system addresses only if you use the SAA3008. The drawing below shows an extended message. This example transmits command 36 to address 10.
The first two pulses are a special start sequence. The total duration of these pulses is equal to a normal \
The next bit is a toggle bit. Its value is toggled whenever a key is released, which results in a different code every time a new key is pressed. This allows the receiver to discriminate between new key presses and key repetitions.
The next 4 pulses S3 to S0 represent the sub-system address bits. This would allow for an additional 16 different sub-system addresses, although the SAA3008 can only generate 13 additional sub-system addresses in this mode. Next come the 6 command bits F to A, also sent with MSB first.
The pulse train is terminated by a last pulse, otherwise there is no way to know the duration of bit A. The entire command is repeated (with unchanged toggle bits) for as long as the key is held down. The repetition rate is 121.5ms (55296 periods of the oscillator).

35)Philips RC-MM Protocol
RC-MM was defined by Philips to be a multi-media IR protocol to be used in wireless keyboards, mice and game pads. For these purposes the commands had to be short and have low power requirements. Whether the protocol is actually used for these purposes today is unknown to me. What I do know is that some Nokia digital satellite receivers use the protocol (9800 series).
Features
12 bits or 24 bits per message
Pulse position coding, sending 2 bits per IR pulse Carrier frequency of 36kHz
Message time ranges from 3.5 to 6.5 ms, depending on data content Repetition time 28 ms (36 messages per second) Manufacturer Philips
Transmission timing
In this diagram you see the most important transmission times. The message time is the total time of a message, counting form the beginning of the first pulse until the end of the last pulse of the message. This time can be 3.5 to 6.5 ms, depending on the data content and protocol used.
The signal free time is the time in which no signal may be sent to avoid confusion with foreign protocols on the receiver's side. Philips recommends 1 ms for normal use, or 3.36 ms when used together with RC-5 and RC-6 signals.
Since you can never tell whether
a user has other remote
controls
in use
together with an RC-MM controlled device I would recommend always to use a signal free time of 3.36 ms.
The frame time is the sum of the message time and the signal free time, which can add up to just about 10 ms per message.
Finally the repetition time is the recommended repetition time of 27.778 ms, which allows 36 messages per second. This is only a recommendation and is mainly introduced to allow other devices to send their commands during the dead times.
No provision is made for data collisions between two or more remote controls! This means that there is no guarantee that the messages get across.
39
Modulation
With this protocol a 36 kHz carrier frequency is used to transmit the pulses. This helps to increase the noise immunity at the receiver side and at the same time it reduces power dissipated by the transmitter LED. The duty cycle of the pulses is 1:3 or 1:4.
Each message is preceded by a header pulse with the duration of 416.7 followed by a space of 277.8
s (15 pulses of the carrier), μ
s (10 periods of the carrier). This header is followed by 12 or 24 bits of data. μ
By changing the distance between the pulses two bits of data are encoded per pulse. Below you find a table with the encoding times.
Protocol
RCMM comes in 3 different flavours, called modes. Each mode is intended for a particular purpose and differs mainly in the number of bits which can be used by the application. All data is sent with MSB first.
The 12 bit mode is the basic mode, and allows for 2 address bits and 8 data bits per device family. There are 3 different device families defined: keyboard, mouse and game pad. The 2 address bits provide for a way to use more than 1 device simultaneously. The data bits are the actual payload data.
The 24 bit mode, also know as extended mode, allows more data to be transmitted per message. For instance for multi-lingual keyboards or a high resolution mouse.
In the OEM mode the first 6 bits are always 0 0 0 0 1 1. The next 6 bits are the customer ID (OEM manufacturer).
My observation
showed
that Nokia used the code 1 0 0 0 0 0
for their 9800 series
digital satellite receivers.
Finally the last 12 bits are the actual pay load data.

36) Philips RC-6 Protocol
RC-6 is, as may be expected, the successor of the RC-5 protocol. Like RC-5 the new RC-6 protocol was also defined by Philips. It is a very versatile and well defined protocol. Because of this versatility its original
definition
is many pages long. Here on
my page I will only summarize
the most important
properties of this protocol.
Features
Different modes of operation, depending on the intended use Dedicated Philips modes and OEM modes
Variable command length, depending on the operation mode Bi-phase coding (aka Manchester coding) Carrier frequency of 36kHz Manufacturer Philips
Modulation
RC-6 signals are modulated on a 36 between 25% and 50%.
Data is modulated using Manchester coding. This means that each bit (or symbol) will have both a mark and space in the output signal. If the symbol is a \half is a space. If the symbol is a \Please note that this is the opposite of the RC-5 protocol!
The main timing unit is 1t, which is 16 times the carrier period (1/36k * 16 = 444With RC-6 a total of 5 different symbols are defined:

μ
kHz Infra Red carrier. The duty cycle of this carrier has to be
The leader pulse, which has a mark time of 6t (2.666ms) and a space time of 2t (0.889ms). This leader pulse is normally used to set the gain of the IR receiver unit.

Normal bits, which have a mark time of 1t (0.444ms) and space time of 1t (0.444ms). A \and \
Trailer bits, which have a mark time of 2t (0.889ms) and a space time of 2t (0.889ms). Again a \
The leader and trailer symbols are only used in the header field of the messages, which will be explained in more detail below.
RC-6 Mode 0
I can only describe operation mode 0 because I have never actually seen other modes in use than the one my Philips TV understands. The way I understand it the other modes can vary extremely from mode 0.
Mode 0 is a dedicated Philips Consumer Electronics mode. It allows control of up to 256 independent devices, with a total of 256 commands per device.
The command is a concatenation of different information. I will cover these different components from left to right. Header field
The Header field consists of 3 different components.
First the leader symbol LS is transmitted. Its purpose is to adjust the gain of the IR receiving unit.
This leader symbol is followed by a start bit SB which always has the value \to calibrate the receiver's timing.
The mode bits mb2 ... mb0 determine the mode, which is 0 in this case, thus all three bits will be \
Finally the header is terminated by the trailer bit TR. Please note that the bit time of this symbol is twice as long as normal bits! This bit also serves as the traditional toggle bit, which will
42
be inverted whenever a key is released. This allows the receiver to distinguish between a new key or a repeated key.
Control Field
This field holds 8 bits which are used as address byte. This means that a total of 256 different devices can be controlled using mode 0 of RC-6. The msb is transmitted first. Information Field
The information field holds 8 bits which are used as command byte. This means that each device can have up to 256 different commands. The msb is transmitted first. Signal Free Time
The Signal Free time is a period in which no data may be transmitted (by any device). It is important for the receiver to detect the signal free time at the end of a message to avoid incorrect reception. The signal free time is set to 6t, which is 2.666ms.
43
37) Philips RC-5 Protocol
The RC-5 code from Philips is possibly the most used protocol by hobbyists, probably because of the wide availability of cheap remote controls. The protocol
is well
defined
for different
device
types
ensuring
compatibility
with
your
whole
entertainment system. Lately Philips started using a new protocol called RC-6 which has more features.
Features
5 bit address and 6 bit command length (7 command bits for RC5X) Bi-phase coding (aka Manchester coding) Carrier frequency of 36kHz
Constant bit time of 1.778ms (64 cycles of 36 kHz) Manufacturer Philips
Modulation
The protocol uses bi-phase modulation (or so-called Manchester coding) of a 36kHz IR carrier frequency. All bits are of equal length of 1.778ms in this protocol, with half of the bit time filled with a burst of the 36kHz carrier and the other half being idle. A logical zero is represented by a burst in the first half of the bit time. A logical one is represented by a burst in the second half of the bit time. The pulse/pause ratio of the 36kHz carrier frequency is 1/3 or 1/4 which reduces power consumption.
Protocol
The drawing below shows a typical pulse train of an RC-5 message. This example transmits command $35 to address $05.
44
The first two pulses are the start pulses, and are both logical \elapsed before the receiver will notice the real start of the message.
Extended RC-5 uses only one start bit. Bit S2 is transformed to command bit 6, providing for a total of 7 command bits. The value of S2 must be inverted to get the 7th command bit though!
The 3rd bit is a toggle bit. This bit is inverted every time a key is released and pressed again. This way the receiver can distinguish between a key that remains down, or is pressed repeatedly.
The next 5 bits represent the IR device address, which is sent with MSB first. The address is followed by a 6 bit command, again sent with MSB first.
A message consists of a total of 14 bits, which adds up to a total duration of 25 ms. Sometimes a message may appear to be shorter because the first half of the start bit S1 remains idle. And if the last bit of the message is a logic \
As long as a key remains down the message will be repeated every 114ms. The toggle bit will retain the same logical level during all of these repeated messages. It is up to the receiver software to interpret this auto repeat feature.
PS: I had rather a big error on this page for quite some time. For some mysterious reason the LSB and MSB of the address and command were reversed. I can recall correcting this error before, but somehow an old version of the description must have sneaked its way up to the internet again
45
38) Sony SIRC Protocol
I've collected and combined some information found on the internet about the Sony SIRC protocol. I must
admit
that I have never worked
with this particular
protocol,
so I could
not verify
that all
information is valid for all situations. It appears
that 3 versions
of the protocol
exist:
12-bit
(described
on this page),
15-bit
and 20-bit
versions. I can only assume that the 15-bit and 20-bit versions differ in the number of transmitted bits per command sequence.
Please note that a lot of confusing documentation about the SIRC protocol exists on the internet. At first I contributed to the confusion by assuming the correctness of the source documents I found myself, until someone with some SIRC experience informed me about my errors. I double checked his story with a universal remote control and a digital storage oscilloscope, and found that the bit and word order I documented were indeed wrong.
The protocol information on this page is according to my own measurements and should be correct now.
Features
12-bit, 15-bit and 20-bit versions of the protocol exist (12-bit described here) 5-bit address and 7-bit command length (12-bit protocol) Pulse width modulation Carrier frequency of 40kHz Bit time of 1.2ms or 0.6ms
Modulation
The SIRC protocol uses a pulse width encoding of the bits. The pulse representing a logical \long burst of the 40kHz carrier, while the burst width for a logical \separated by a 0.6ms long space interval. The recommended carrier duty-cycle is 1/4 or 1/3.
Protocol
46
The picture above shows a typical pulse train of the SIRC protocol. With this protocol the LSB is
transmitted first. The start burst is always 2.4ms wide, followed by a standard space of 0.6ms. Apart from signalling the start of a SIRC message this start burst is also used to adjust the gain of the IR receiver. Then the 7-bit Command is transmitted, followed by the 5-bit Device address. In this case Address 1 and Command 19 is transmitted.
Commands are repeated every 45ms(measured from start to start) for as long as the key on the remote control is held down.
47
39) Sharp Protocol
I only have little information on this protocol. It is used in VCRs that are produced by Sharp, that is why I gave it the name Sharp protocol.
Features
8 bit command, 5 bit address length Pulse distance modulation Carrier frequency of 38kHz Bit time of 1ms or 2ms
Modulation
The Sharp protocol uses a pulse distance encoding of the bits. Each pulse is a 320burst (about
12 cycles).
A logical
\takes 2ms to transmit,
while a logical
s long 38kHz carrier μ\is only 1ms. The
recommended carrier duty-cycle is 1/4 or 1/3.
Protocol
In the picture above you see a typical pulse train sending the command $11 and address $03. The Address is sent first and consists of 5 bits. Next comes the 8 bit command. In both cases the LSB of the data is sent first.
I don't exactly know the purpose of the Expansion and Check bits that follow the command. Both bits were fixed in the example that I had at hand.
I can only guess that the Check bit is used to find out whether we are receiving a normal or inverted message.
48
One complete command sequence consist of 2 messages. The first transmission is exactly as described above. The second transmission follows the first one after a delay of 40ms, and basically contains the same information. The only difference is that all bits, except those from the address field, are inverted. This way the receiver can verify if the received message is reliable or not.
49
40) Nokia NRC17 Protocol
The Nokia Remote
Control protocol
uses 17
bits to
transmit
the IR commands,
which immediately
explains the name of this protocol.
The protocol was designed for Nokia consumer electronics. It was used during the last few years in which Nokia produced TV sets and VCRs. Also the sister
brands like Finlux and Salora used this protocol.
Nowadays the protocol is mainly used in Nokia satellite receivers and set-top boxes.
Features
8 bit command, 4 bit address and 4 bit sub-code length Bi-phase coding
Carrier frequency of 38kHz Constant bit time of 1ms Battery empty indication possible Manufacturer Nokia CE
Modulation
The protocol uses bi-phase (or so-called NRZ - Non Return to Zero) modulation of a 38kHz IR carrier frequency. All bits are of equal length of 1ms in this protocol, with half of the bit time filled with a burst of the 38kHz carrier and the other half being idle. A logical one is represented by a burst in the first half of the bit time. A logical zero is represented by a burst in the second half of the bit time.
The pulse/pause ratio of the 38kHz carrier frequency is 1/4 which helps to reduce power consumption.
Protocol
The drawing below shows a typical pulse train of an NRC17 message. This example transmits command $5C to address $6 sub-code $1.
