Looks like the mystery Raleigh announcement for today is indeed mobile digital TV on a Raleigh bus. WRAL posted the announcement 10 minutes ago. According to the story, riders of Raleigh’s R-Line downtown circulator will be able to watch digital TV as well as get city updates and real-time information on bus routes. By August 2009 four CAT buses will also provide the service. The article also mentions “two-way” and “interactive” but doesn’t provide details about what this means. WiFi on the buses?
