An apparatus for seamless connectivity between a narrow-band network like the Internet and an interactive TV wide-band network, and methods of operating the same, support on-the-fly translation and routing of data between the Internet and the interactive TV wide-band network. The apparatus for interfacing between a wide-band network and a narrow-band network comprises a decoder having a decoder input, a first decoder port, and a second decoder port, which receives wide-band data from the wide-band network via the second decoder port and decodes the wide-band data to provide decoded data in response to decoder requests from the decoder input. A gateway coupled to the decoder, the narrow-band network, and the wide-band network, having a first gateway port to receive the decoder requests from the first decoder port, a second gateway port to interface with the narrow-band network, and a third gateway port to interface with the wide-band network, retrieves requested data from the narrow-band network in response to the decoder requests and transfers the requested data to the wide-band network for transfer to the decoder.
