With the blessing of government regulators, a consortium of leading TV researchers and manufacturers has nearly completed developing a digital HDTV standard, ending a process that began more than five years ago.

The group believes HDTV sets and programming could appear as early as 1996.

Consumers will have to spend an extra $1,000 to $2,000 for an HDTV set, industry experts said.
