The latest version of HDMI, v1.3, will make its debut at the 2007 January CES. So says Silicon Image marketing director Joe Lee, who states that the new standard is nearing final approval. AV receivers, displays and HD DVD and Blu-ray disc players will all benefit from the new connector, as V1.3 brings several refinements to the HDMI family, including support for advanced audio codecs, such as Dolby TrueHD and DTS HD, and improved video capabilities.
V1.3 expands the bandwidth of the connection to 10.2Gbps, which allows refresh rates up to 120Hz and color bit depth to 48-bit RGB.
Lee admits however that it could take the industry some time to implement hardware to take advantage of the increased capacity of the connection: “It’s possible that Media PCs may become the first products to take advantage of the greater bandwidths, since PCs have very powerful graphics and processing capabilities,” he speculates.
V1.3 will also herald a new form factor, in the shape of a mini connector for digital camcorders.
Currently, HDMI 1.1 and 1.2 standards support all mandatory surround formats including 5.1-channel PCM up to 192kHz/24 bits. Version 1.2 also delivers DVD-Audio and SACD streams, 1080p/60Hz video, 24-bit RGB color, up to eight channels of uncompressed 192kHz/24-bit audio and the CEC bidirectional communications protocol, dubbed HDAVI by Panasonic.
Functionality though is dependent on the hardware at each end of the equipment chain.
