    摘要: An interactive video guide system is provided in which nationally generic guide data, local guide data, and interactive video guide object code are transmitted to set-top decoder units located in customers' homes. Initially, nationally generic data or program information from a variety of sources is gathered together via modem at a central processing unit, and then manipulated, parsed and formatted into a national database compatible for use by a head end computer. This information is typically collected and updated on a daily basis. The manipulated nationally generic data is then transferred via modem to a transmitter for uplink to a selected telecommunications satellite. The satellite signal is then received by one or more local satellite CATV head end receivers which then forward a video base band signal carrying the nationally generic data to associated local head end computers. At the local head end computer, the nationally generic data is again manipulated, winnowed, parsed and processed to suit the requirements of the particular local market. Local guide data and interactive video guide object code may then be added to the nationally generic data and then the combined data and object code is transmitted over the CATV system to one or more decoder units in the consumers' homes.

    摘要: Systems and methods for determining an inventory. The methods comprise: placing an RFID tag in a first operational mode in which at least one communication operation or device of the RFID tag is disabled or bypassed; performing first operations by the RFID tag to determine when it is time to begin communications in accordance with the time slotted communications scheme; transitioning an operational mode of the RFID tag from the first operational mode to a second operational mode in which the communication operation(s) or device of the RFID tag is enabled or no longer bypassed, in response to a determination that it is time for the RFID tag to begin communications; and transitioning the operational mode of the RFID tag back into the first operational mode when the RFID tag's communications with a remote tag reader for inventory determination purposes are complete or a time slot has expired.
