kwikwai k1-092 : THE BRIDGE

Along with any external controller (home automation system, HTPC, …), the k1-092 model is deployed as a bridge in order to control HDMI devices by participating in the HDMI-CEC exchanges.

The k1-092 bridge is the element to add to a media center in order to switch on/off the TV or select its source.


generic use case

drive HDMI CEC devices

Using kwikwai, your home automation system can control HDMI devices by participating in the HDMI CEC exchanges between them. This can happen over a usb, ethernet or serial connection. Many HDMI CEC capable devices answer to status queries, and are capable to process IR codes sent over CEC. In many cases, kwikwai can advantageously replace traditional control methods such as IR stickers and RS-232 ports.

media center use case

A single USB cable between your media center and kwikwai is all it takes to power kwikwai and exchange CEC messages, for example to turn off the TV once the show is over.

kwikwai k110 : THE BRIDGE & CONTROLLER

On top of the bridge model, the k110 is able to detect CEC messages or HPD & 5V state changes, and react by sending serial commands, This way it acts as a controller for AV devices.

Some typical AV control scenarios are to drive video conference system and meeting room display.

under the controller hood

Used as a controller, kwikwai can detect CEC messages or, for non CEC capable devices, modifications of the 5V and HPD (Hot Plug Detect) state. As a reaction, kwikwai can send CEC or serial commands.


serial device control use cases

control serial devices

Thanks to its controller feature, kwikwai is able to control devices through serial commands (typically beamers that are usually not CEC capable).

the video conference use case

For instance, it is possible to switch on a beamer and select the appropriate source at the startup of a video conference by detecting the sent CEC commands. And when the conference is finished, a standby command is sent.

HDMI CEC control use case

control HDMI CEC devices

As a controller, kwikwai can detects changes in the HPD or 5V state.

the powerpoint use case

This way it is possible to switch on a monitor and select the appropriate source when connecting a laptop.  The monitor is then switched off when the HDMI cable is disconnected from the laptop.

the TV box use case

It is also possible to switch on a TV set, and select the appropriate source, when turning on TV box.  Depending on the configuration the TV may be send to standy when turning off the box.

kwikwai k110 pro : THE TEST TOOL

Thanks to its web GUI, the k110 pro is the perfect tool for testing CEC devices capabilities and investigating AV control scenarios.
The web interface displays and decodes CEC, E-EDID as well as the HPD and 5V states.

With kwikwai k110 pro, you can diagnose CEC chatter between devices, decode E-EDID, or fine tune AV control scenarios.

diagnose CEC chatter

Kwikwai’s k110 pro web interface displays and decodes CEC messages exchanged between devices on the HDMI bus. It can also send messages.

This allows to discover what messages your devices support, to investigate any proprietary ones, and try control scenarios comfortably. Device manufacturers can of course use kwikwai as an affordable, CEC only HDMI test tool.

decode E-EDID

Kwikwai reads and decodes all the information contained in the E-EDID.

This includes the HDMI data block, with the sink physical address, as well as all the newest 3D related fields. The raw E-EDID is provided for copy pasting.

fine tune AV control scenarios

Kwikwai monitors some HDMI signals (CEC messages or HPD/5V state change) and react by sending a serial or CEC command.

Serial commands can be sent with a minimal interval of time and with a configurable delay.

In order to foster CEC exchange on the bus, kwikwai can simulate the presence of a device by acknoledgng messages.

Which model do I need ?

Most of our customers start with a k110 pro; it’s the most versatile and it can be used as an everyday test tool and/or to develop one’s specific application.
All models have the very same machine to machine APIs, so for deployment, the cheaper k110 (or k1-092, depending on the required features) can be used.
