Verizon Wireless, whose CDMA-based cellular business has been tightly integrated with Qualcomm Inc.'s technology, announced earlier this year its adoption of Qualcomm's proprietary MediaFlo, a mobile-TV spec that competes directly with the DVB-Handheld standard embraced by Modeo. Other U.S. wireless carriers are said to be leaning toward MediaFlo or to have remained noncommittal.
While the management change at Modeo suggests larger structural problems in the U.S. mobile TV market, a source close to Modeo said it was too early to write DVB-H's "obituary." The source said the Modeo move had stemmed from a management failure and not any technological failing on the part of DVB-H.
Several countries have rolled out commercial mobile-TV services using DVB-H since the summer. "DVB-H is a field-tested, field-proven, well-validated technology," the source added.
