Abstract

A network datacast system includes a plurality of transmission facilities. Each transmission facility receives primary programs from one or more media studios. Each transmission facility also receives ancillary data programs from a network datacast center. Each transmission facility broadcasts a wireless signal that includes a primary channel and at least one ancillary data channel. The transmission facilities contemporaneously transmit the ancillary programs on the ancillary data channels. A network datacast receiver contemporaneously receives the wireless signals and extracts the datacast programs from each datacast signal. The extracted datacast programs are stored in the receiver for subsequent output to the user.
