Abstract: This invention relates to compression of prediction error in motion compensated video coding schemes. Prediction frame and motion vectors are used to extract useful information about the properties of the prediction error signal, e.g. its location, directionality, etc. This information does not need to be transmitted because the decoder of the proposed system includes means to extract this information. Information extracted by the encoder and decoder is used to adapt prediction error coding scheme which gives substantial bitrate reductions.

Abstract: A WAP telephone handset has a display (5) which displays a WML card that includes a table consisting of data cells (C) arrayed in rows and columns. A focus (22) can be scrolled through the rows of the display and a row selected. Not all the columns need be displayed. The selected row is then displayed as a column so that the focus can be scrolled through data items in the column. The column widths may be scaled downwardly to increase the number displayed when the table includes a larger number of columns. Navigation indicators may be provided to indicate the size of the array and the position of the focus within the array.

Abstract: The invention relates to a method and arrangement for ciphering an information transfer connection. The invention can be advantageously applied in a TDMA (Time Division Multiple Access) cellular system offering broadband circuit switched services. An essential idea of the invention is that the information to be ciphered in a transmission burst is divided into at least two blocks (730) and said blocks are ciphered in ways that are not identical with each other (750 to 770). Then the reliability of ciphering is better because the amount of information encoded using one and the same ciphering algorithm and key is smaller. In addition, the reliability of the ciphering can be varied by changing the number and/or size of the information blocks in a burst.

Abstract: A method for operating a mobile station includes steps of (A) operating an RF transmitter power detector to obtain an output signal that is indicative of a magnitude of RF power transmitted by the mobile station; (B) processing the output signal to determine a time-varying characteristic of the output signal; and (C) determining a value of the Adjacent Channel Power Ratio (ACPR) from the time-varying characteristic. A further step uses the determined value of the ACPR to control a DC bias current, and therefore the output power capability, of a transmitter amplifier. In one embodiment the time varying characteristic of the output signal includes a frequency spectrum, and the step of processing makes a comparison of the power in one portion of the frequency spectrum corresponding to a desired channel frequency to the power in another portion of the spectrum corresponding to an adjacent channel frequency.
