The HDMI 1.4 specification was announced in June 2009 and contained many important capabilities that have further revolutionized multimedia devices. While HDMI 1.3 made significant improvements by doubling the data rate, providing up to 2.8 trillion colors, lossless audio formats, 120 Hz frame rates and 1440p resolution modes, HDMI 1.4 has further added some subtle but highly innovative features that reinforced consumers’ perception that HDMI equates to simplicity, reliability and performance.  The key features added in HDMI 1.4 included: 1) HEAC, 2) 3D modes, 3) 4K resolution, 4) real time content recognition & 5) additional color space for digital still cameras. Synopsys is one of the very few companies to support ALL of the HDMI 1.4 features including the HDMI Ethernet and Audio Return Channel (HEAC).
