<p>CEC<sup id="cite_ref-HDMI1.3a_3-3" class="reference"><a href="#cite_note-HDMI1.3a-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> is a separate electrical signal from the other HDMI signals. This allows a device to disable its high-speed HDMI circuitry in <a href="Sleep_mode" title="Sleep mode">sleep mode</a>, but be woken up by CEC. It is a single shared bus, which is directly connected between all HDMI ports on a device, so it can flow through a device which is completely powered off (not just asleep).

</p><p>The bus is electrically identical to the <a href="AV.link" title="AV.link">AV.link</a> protocol, but CEC adds a detailed higher-level message protocol.

</p><p>The bus is an <a href="Open-collector" class="mw-redirect" title="Open-collector">open-collector</a> line, somewhat like <a href="I%C2%B2C" title="I²C">I²C</a>, <a href="Pull-up_resistor" title="Pull-up resistor">passively pulled</a> up to +3.3 V, and driven low to transmit a bit.

</p><p>Similarities to I²C include:

</p>

<ul><li>Low-speed serial bus</li>

<li>Open-collector with passive pull-up</li>

<li>Speed limited by distributed <a href="Capacitance" title="Capacitance">capacitance</a></li>

<li>Receiver can convert a transmitted 1 bit to a 0</li>

<li>Multiple masters allowed via arbitration: sending a 1 bit and observing a 0 indicates loss</li>

<li>Byte-oriented protocol</li>

<li>Each byte has an acknowledge bit appended</li>

<li>Special start signal</li></ul>

<p>Differences from I²C:

</p>

<ul><li>Single wire rather than two wires</li>

<li>Bits sent with fixed timing rather than separate clock</li>

<li>1000× lower speed (417 bit/s instead of 400 kbit/s)</li>

<li>Four address bits rather than seven</li>

<li>Defined protocol for dynamic address allocation</li>

<li>Header includes both initiator and recipient address</li>

<li>No special stop signal; instead, each byte has an end of message flag appended</li>

<li>No "read" operations; all data bytes in a frame are sent from transmitter</li>

<li>Instead, "get" requests solicit response frames</li>

<li>Every device must be able to transmit</li>

<li>Detailed specification of meaning of bytes after the address</li></ul>

<p>Each bit begins with the line pulled low (falling edge), a delay indicating the bit value, a rising edge, and further delay until the start of the following bit.

</p><p>Normal data bits are <span class="nowrap">2.4<span style="margin-left:0.225em;margin-right:0.225em;">±</span>0.35 ms</span> long. A logic 1 is held low for <span class="nowrap">0.6<span style="margin-left:0.225em;margin-right:0.225em;">±</span>0.2 ms</span>, while a logic 0 is held low for <span class="nowrap">1.5<span style="margin-left:0.225em;margin-right:0.225em;">±</span>0.2 ms</span>. The receiver samples the line at <span class="nowrap">1.05<span style="margin-left:0.225em;margin-right:0.225em;">±</span>0.2 ms</span> after the falling edge, then begins watching for the following bit <span class="nowrap">1.9<span style="margin-left:0.225em;margin-right:0.225em;">±</span>0.15 ms</span> after the falling edge.

</p><p>A receiver can convert a transmitted 1 bit to a 0 bit by pulling the line low within 0.35 ms of the falling edge, and holding it until the 0 bit time. The transmitter observes the bus during its own transmissions to detect this condition. This is used to <a href="Acknowledgement_(data_networks)" title="Acknowledgement (data networks)">acknowledge</a> a transmission.

</p><p>Each frame begins with a special <a href="Start_bit" class="mw-redirect" title="Start bit">start bit</a>, held low for <span class="nowrap">3.7<span style="margin-left:0.225em;margin-right:0.225em;">±</span>0.2 ms</span> and then allowed to rise, for a total duration of <span class="nowrap">4.5<span style="margin-left:0.225em;margin-right:0.225em;">±</span>0.2 ms</span>. Any device may send a start bit after observing the bus idle for a suitable number of bit times. (Normally, 5 bit times, but 7 bit times immediately after a successful transmission to facilitate fair sharing of the bus, and 3 bit times between a failed transmission and its retransmission.)

</p><p>This is followed by up to 16 bytes. Each byte consists of ten bits: eight data bits (transmitted msbit-first, in <a href="Big-endian" class="mw-redirect" title="Big-endian">big-endian</a> order), an "end of message" bit (set to 1 after the last byte of a frame), and an "acknowledge" bit.

</p><p>For single-recipient messages, the acknowledge bit operates similarly to I²C: it is transmitted as a 1 bit, and the receiver pulls it down to a 0 bit to acknowledge the byte.

</p><p>For broadcast messages, the acknowledge bit is inverted: it is still transmitted as a 1 bit, but is pulled down to a 0 bit by any receiver which <i>rejects</i> the byte.

</p><p>The first byte of each CEC frame is a header containing the 4-bit source and destination addresses. If the addressed destination exists, it acknowledges the byte. A frame consisting of nothing but the header is a <a href="Ping_(networking_utility)" title="Ping (networking utility)">ping</a> which simply checks for the presence of another device.

</p><p>The address 15 (1111) is used for the broadcast address (as a destination) and unregistered devices (as a source) which have not yet chosen a different address. Some devices do not need to receive non-broadcast messages and so may use address 15 permanently, notably remote control receivers and HDMI switches. Devices which need to receive addressed messages need their own address. A device obtains an address by attempting to ping it. If the ping is unacknowledged, the device claims it. If the ping is acknowledged, the device tries another address.

</p><p>The second byte is an opcode which specifies the operation to be performed, and the number and meaning of following parameter bytes. For example, a user press on a remote control will generate a 3-byte frame: a header byte, a <code><User Control Pressed></code> opcode (0x44), and an operand byte identifying the button. Including the initial idle time and extra-long start bit, this takes 88.5 ms (37 bit times). A later <code><User Control Released></code> opcode (0x45) has no operands.
