                              Prospectus Supplement
                       (To Prospectus Dated July 21, 2000)

         You should read this prospectus supplement and the related prospectus
carefully before you invest. Both documents contain information you should
consider when making your investment decision.

         On July 31, 2000, we issued a drawdown notice to Techrich International
Limited in connection with the common stock purchase agreement dated April 9,
2000, evidencing an equity draw down facility between us and Techrich. This
notice offered to sell up to $5,000,000 of our common stock to Techrich based on
the formula in the stock purchase agreement, during the 22 day period beginning
on August 1, 2000 and ending on August 30, 2000, but at not less than $3.50 per
share. During the second 11 days, Techrich purchased a total of 705,999 shares
of our common stock at an average purchase price of $3.54 per share. These
purchases resulted in aggregate proceeds of $2,500,000 being paid and released
from escrow to us by Techrich. In addition, Techrich received warrants to
purchase up to 49,712 shares of common stock, with an exercise price of $4.22436
per share, as part of the purchase. Ladenburg Thalmann & Co. Inc. received
$75,000 as a placement fee in connection with this drawdown. We will use the
proceeds from this drawdown to retain engineering and production personnel to
complete set-top box design and for general operating purposes.

         The attached prospectus relates to the resale of shares acquired by
Techrich pursuant to the stock purchase agreement and pursuant to the exercise
of warrants held by Techrich and Ladenburg. As of the date of this prospectus
supplement, Techrich owns 807,462 shares of common stock and Ladenburg owns
250,000 shares of common stock, including 101,463 and 250,000 shares,
respectively, issuable upon the exercise of warrants. Because Techrich and
Ladenburg may sell some or all of these shares, and because there are currently
no agreements, arrangements or understandings with respect to the sale of any of
these shares, we cannot estimate the actual amount of shares that they will hold
after the completion of the offering.

            THE DATE OF THIS PROSPECTUS SUPPLEMENT IS AUGUST 31, 2000
