Saw an ad yesterday for AIRBOX Television on local CH33. 855-247-2697 they are using subchannels on ION and MPEG4 broadcasts. Based on USDTV 2005-2006 trying the same thing I would suggest staying away from them. With out enough capital to continue the service there are too few subchannels on one TV channel to be successful. Also the customer must pay $100 for the receiver and provide the reception equipment. Ten years ago it might have worked but with the number of subchannels available $20 a month for 1 channel of a premium movie service seems too high. Even though their $100 box allows free reception of the local digital channels so don't most TVs today.
