Abstract
Methods and apparatus for supplying unbound applications with data via in-band program channel signaling are described. Unbound applications are STB or other customer premise device applications which continue to run when a tuner in the device changes between program channels. Applications executed in a STB, in accordance with the present invention, e.g., eBIF applications, continue to run despite changes in program channels with data being supplied via in-band signaling, out of band signaling, or a combination of in-band and out of band signaling. The methods and apparatus are well suited for supporting delivery of program catalog information relevant to an individual program channel using in-band signaling reducing or eliminating the need to delivery a multi-channel program catalog via out of band signaling to support various VOD applications.
