    摘要： A hand held data entry terminal that, upon initialization of a data entry program downloaded from a host computer, is capable of capturing product data, through either a terminal scanner or a data entry keypad, at locations remote from the host computer. A data entry program is downloaded to a battery-powered data entry terminal from a central host computer via an RF data transceiver located in the terminal. If the terminal scanner is functional and the product contains the necessary coded representations of data, the scanner may be enabled, through a first trigger located on a terminal handle, to scan the coded representations of data. Alternatively, the terminal operator may enter alpha/numeric product data through the terminal keypad. The data entry program contains a stack of key definition tables for the terminal keypad, allowing the terminal to be designed with a minimum number of data entry keys and a terminal display of maximum size. If the keypad mode of data entry is used, the terminal operator may scroll through the alternate key definition tables by using certain command keys, or via a second trigger located on the terminal handle, to select the proper key definition table for a particular mode of data entry or to select a particular data entry command. Regardless of the mode of data entry used, the data entered into the terminal is stored in a buffer at the terminal. Once all data has been entered into the buffer, the processor, upon receiving a SEND command, sends the data to the host computer via the terminal RF transceiver.

    摘要： In a digital network that includes a plurality of devices, which include multiple devices that transmit transport streams, a system and method are provided for discovering and mapping the transport streams and the plurality of devices included in the digital network. In the preferred embodiment, the system includes a controller that, among other things, receives network messages from the plurality of devices and determines or assigns transport stream identifiers in the network such that transport stream identifier conflicts do not occur. In the preferred embodiment, the plurality of devices are adapted to respond to a first message by sending a network message to the controller, and the devices are adapted to monitor their received transport stream(s) and respond to changes by sending a second network message to the controller. The network messages include a transport stream identifier, which is associated with a transport stream, and a device identifier, which is associated with the device that sent the message. The controller uses the received network messages to generate the transport stream map.

    摘要： A decoder checks a table within its received input signal and tunes to at least one of the listed frequencies to determine its associated service group within a subscriber television system. The associated service group associates the decoder with the modulators, transport streams, and other components providing services and programming to that particular decoder. The decoder transmits its associated service group to the subscriber television system headend. The subscriber television system then knows the services and programming available on that particular decoder. The decoder can periodically verify its associated service group and, if the service group is changed, notify the headend. By establishing decoders for auditing the system, the definition of the service groups can be established or updated when components or configurations are introduced or changed.
