Abstract: Systems and methods of decoding data streams and conserving power are described. In some embodiments, a stream of data containing audio and other data is divided into a plurality of timeslots. A first timeslot of the plurality of timeslots is allocated to a first service. A grant allocation message which indicates a location of the first timeslot allocated to the first service is generated. The grant allocation message and the plurality of timeslots are transmitted to a receiver. The transmission system and receiver may be compatible with NRSC-5. The receiver may receive and decode the grant allocation message to identify OFDM symbols that carry information regarding the first service. The receiver may also receive the plurality of timeslots. The receiver may set a power mode of a component during OFDM symbols that indicate a status of the first service.

Abstract: An interactive device/system of and method for delivery, receipt and/or decoding of and/or response to keyed or tagged video content provided in connection with one or more video broadcasts (for example, television or streaming video). Responsive thereto, the system and method may deliver and/or receive video and/or audio information. Such delivery and/or receipt of video and/or audio information may be responsive to content embedded in the broadcast but not visually observed, responsive to broadcast content that is visually observed and then parsed and correlated with a predetermined response, and responsive to a user/operator instruction, input and/or request. The interactive video receiving device may determine a video-based broadcast is an interactive video-based broadcast, wherein, the device automatically provides interaction options and or based on a response by the user/viewer to the video-based broadcast, the video receiving device transmits “interest-level” data (i.e.
