HDMI 1.4 brings Ethernet and upstream audio over 1 cable
Yesterday the list of features which will be incorporate into upcoming HDMI 1.4 specification, was announced. The major ones are two-way data and two-way audio support. The two-way data transferring will allow to use HDMI cable to send or receive data in the local network with speeds of up to 100 Mbps. This means that the only one device from the A/V stack should be connected via Cat5. The rest will get their IP connectivity over HDMI.
If TV has a built-in tuner the S/PDIF cable should be used to get sound on the audio receiver. With HDMI 1.4 it won’t be needed thanks to supporting of upstream audio. As result only one HDMI cable will be used instead of three.
The rest features are following:
* HD resolutions up to 4096×2160
* 3D up to 1080p definition
* “Real-Time Content Recognition†(adjusting video settings automatically based on connected device)
* Additional color spaces, especially for digital still cameras
* Micro connectors
* Automotive connectors
