The Digital Interface for Video and Audio (DIVA or DiiVA) was a proposal for a bi-directional audio/video interface for transmitting both compressed and uncompressed digital streams.

It was developed by Synerchip Company, Limited, based in Guangzhou and Sunnyvale, California.{{Cite news|title=Synerchip Raises $10.5 Million Series C Round |url=http://www.jafcoasia.com/newsroom/SYNERCHIP%20Press%20Release.pdf |work=Press Release |date=April 19, 2010 |url-status=dead |archiveurl=https://web.archive.org/web/20130319011542/http://www.jafcoasia.com/newsroom/SYNERCHIP%20Press%20Release.pdf |archivedate=2013-03-19 }}

DIVA supports a downstream data rate (from source to display) of 13.5 Gbit/s which is capable of deep color at resolutions higher than 1080p.{{cite web |url=http://www.diva-interface.org/technology.html |title=Technology |publisher=DIVA Promoters Group |url-status=dead |archiveurl= https://web.archive.org/web/20090925110030/http://www.diva-interface.org/technology.html |archivedate= September 25, 2009 |accessdate= June 5, 2013 }}

DIVA also supports a 2.25 Gbit/s bi-directional communication data channel that can carry multiple sub-channels (audio, control, compressed video, etc.). This gives DIVA a raw bi-directional data rate of 18 Gbit/s or a usable bi-directional data rate of 14.4 Gbit/s (because of 8b/10b encoding).{{cite news |title=Synerchip Reveals Aim with New AV Interface 'DIVA' |publisher=Tech On |url=http://techon.nikkeibp.co.jp/english/NEWS_EN/20080609/153012/?ST=english_PRINT |author=Naoki Asakawa |date=2008-06-09 | accessdate=2008-07-02}} DIVA was demonstrated at the China Digital Living Forum & Showcase 2008 using a single Category 6A cable.{{cite web |url= http://www.prnewswire.com/news-releases/diva-consortium-unveils-a-new-interface-standard-for-next-generation-interactive-digital-tv-and-ce-networking-57278707.html |title=DIVA consortium unveils a new interface standard for next-generation interactive digital TV and CE networking |work= Press release |date= May 21, 2008 |accessdate= June 5, 2013 }} The DIVA Promoters Group was formed by Changhong, Haier, Hisense, Konka, Panda, Skyworth, SVA, TCL Corporation and Synerchip.{{cite web |url= http://www.diva-interface.org/about.html |title=About DIVA |publisher=DIVA Promoters Group |url-status=dead |archiveurl= https://web.archive.org/web/20090106190346/http://www.diva-interface.org/about.html |archivedate= January 6, 2009 |accessdate= June 5, 2013 }}

In February 2008, the DIVA Promoters Group hoped to finish the specs for DIVA by the end of 2008 and have DIVA chips released in 2009 or 2010.
