It’s kwikwai<\/em>. And in a single sentence, kwikwai augments the capabilities of HDMI CEC, the control channel that lurks into each and every HDMI connection out there.<\/p>\n

Confused?<\/p>\n

Some background<\/h3>\n

Similarly to what happened between Blu-ray<\/a> and HD DVD<\/a>, a strong leader emerged from the fierce battles between DVI<\/a>, IEEE 1394 (a.k.a. FireWire)<\/a>, DisplayPort<\/a> and HDMI<\/a>. The force was with HDMI, which became the de-facto consumer high-definition digital interconnect.<\/p>\n

For audio and video, things are working almost as well today between vendors with HDMI as they did during the golden age of RCA connectors and component connections.<\/p>\n

For the CEC control channel however, things are less rosy.\u00c2\u00a0For one its support is not mandated by the standard, it’s only optional \u00e2\u20ac\u201c so not all HDMI connections are CEC capable.<\/p>\n

Second, marketers have seized the concept for each brand benefit. CE manufacturers have extended the standard with proprietary extensions and branded the result with some snappy brand-specific name (BRAVIA Theater, Viera Link, …).\u00c2\u00a0The extensions often arbitrarily limit interoperability and the naming obscures the fact some level of compatibility is probable \u00c2\u00a0\u00e2\u20ac\u201c but strongly denied in the manual.<\/p>\n

How we fix the problem<\/h3>\n

The intention of kwikwai is to provide a device that:<\/p>\n

    \n
  1. Allows to read the CEC messages exchanged between the connected AV devices. Now the home automation system can detect the TV is turned on or off and react, maybe by dimming lights.<\/li>\n
  2. Allows to inject messages in the system from the outside, to enable, for example, the home automation system to turn off the TV via the HDMI CEC.<\/li>\n
  3. Long term, fixes some of the incompatibility problems between devices, by enabling, say, to replace a message by another to make the Sony TV understand the Panasonic DVD player.<\/li>\n<\/ol>\n

    That’s the idea. It’s a bridge<\/em> between HDMI CEC and home automation systems. Hence it’s name: movies, bridge, river…<\/p>\n

    Now, we’re not sure this helps making the world better, but at least it may help improve our living rooms !<\/p>\n

    Stay tuned.<\/p>\n","protected":false},"excerpt":{"rendered":"
