 MetaTV’s second round of funding for $21M, in April 2002, was led by Cable giants Comcast and Cox Communications.Cox went on to deploy a precursor of the EBIF cable standard developed by MetaTV that focused on unbound applications, which are available independent of a current video program.In 2005, MetaTV contributed the binary wire protocol and user agent specifications to become the basis for the CableLabs standard for interactive television known as EBIF (Enhanced TV Binary Interchange Format).
