Finite audio and video signals are subjected to some digitalizing encoding format and converted into blocks of audio and video words, respectively. For transmission of these blocks via a compact disc, the words are arranged in packets. Each packet has a packet header and a data field. Such a data field comprises either only audio words or only video words. The packet heater indicates whether the associated data field comprises audio or video words. In order to transmit only changes in the pictur...

This apparatus makes use of the existing data collection probe connector on the instrumentation as the port through which the software updates are loaded into the programmable memory devices that are used to store the operational software of the instrumentation. Circuitry is provided in the instrumentation to automatically differentiate between software update data being loaded into the instrumentation and the normal monitoring data that is received from the probe. This is accomplished by the us...

A radio receiver for demodulating and equalizing digital information is disclosed. The receiver receives radio signals and processes the signals to produce data samples which are then stored. Reference values that model what the receiver should receive for various transmitted symbol sequence hypotheses are also stored. The receiver equalizes the received data using the stored reference values to produce symbol detection information, and updates the reference values based on the symbol detection ...

A user I/F unit 200 transmits an instruction given by a user to an access management unit 100 and displays data on a monitor 76. The access management unit 100 transfers requirements to a communication control unit 300 and a data management unit 400 in response to the instruction from the user, transfers data from a communications host to the data management unit 400, and outputs data from a database 410 to the user I/F unit 200. The data management unit 400 writes data into the database 410 and...

The present landmark update system enables route guidance through the use of landmark information which remains always the latest for route guidance, and operates as follows: a navigation device 1 communicates with a landmark server 30 so as to receive to-be-updated landmark information 1001 for guiding the user by utilizing landmarks. Information about any landmark displayed is transferred to the landmark server 30 as cumulative information 1002. The landmark server 30 manages the cumulative in...

A digital television translator includes a digital television receiver for receiving a first digital television signal at a first frequency and generating a digital transport stream from the first digital television signal. The digital transport stream can include original Program and System Information (PSIP) data having RX channel data that is indicative of the first frequency, the first major channel number, and/or the first minor channel number. The digital television translator also include...

A user equipment (UE) operating in a wireless system having at least one base station, communicates with base stations in neighboring wireless systems and conveys information regarding these neighboring wireless systems to the base station of its wireless system, which updates and stores this information for use in handover of UEs. The BS may also obtain updates directly from the base stations of neighboring wireless systems which may include a diversity of systems such as WLANS, Bluetooth, UMTS...

The present invention relates to a method and arrangement for performing a cell update procedure in a cellular communications system. The cellular communication system comprises a plurality of cells, and a first and a second network controllers. A station is initially on a first cell controlled by the first controller and then in a second cell controlled by the second controller. When changing from one cell to another the station sends cell update information and other information to the second ...
