First Claim
1. A cellular television broadcasting system comprising:
- at least one content server for providing service information from a service provider; and
a plurality of cells, each cell including a transmitting facility in communication with at least one content server for transmitting service information and mapping information over at least one over-the-air broadcast television channel, the mapping information including adjacent cell information enabling a remote mobile receiver unit to transition from a current cell to an adjacent cell in order to continue receipt of service information without requiring communication from the receiver unit to the service provider.

Abstract
Information services are provided via an over-the-air television broadcasting system that is segmented into a plurality of cells. Each cell includes one or more transmitting facilities for transmitting service information and mapping information. The mapping information includes adjacent cell information enabling mobile receiver units to transition between cells in order to continue receipt of service information without requiring communication from the receiver unit to the service provider. The transmitting facilities of adjacent cells may operate on the same television channel and/or on different television channels, typically chosen from a frequency set allocated to a given service provider. The service information may include different content in different cells, such as local content specific to each cell. The service information may be provided from one or more content servers in communication with the transmitting facilities.
