Abstract: A method comprising: for each target image portion to be encoded, selecting a preferred one of a set of encoding modes by optimizing a function comprising an estimate of distortion and a measure of bit rate required to encode the target image portion, the encoding modes comprising at least an intra frame mode and an inter frame encoding mode; encoding the target image portion into the encoded video stream using the selected encoding mode; and transmitting the encoded video stream over a lossy channel. The estimate of distortion is based on a contribution from possible new loss over the channel comprising possible loss of the target block, and on a contribution from possible past loss over the channel comprising possible loss in a history of the encoded video stream upon which decoding of the target portion depends. The method comprises accumulating the contribution from past loss over time, such that the estimate of distortion grows irrespective of the contribution from new loss.

Abstract: The present invention relates to a method and a system for estimating a road gradient a by using a sensor fusion. The present invention detects whether at least one dynamic process is affecting said vehicle. Estimation of said gradient a is then conducted by means of the sensor fusion by joint weighting of at least two input signals to said sensor fusion. The at least two input signals comprise an input signal based on an accelerometer and an input signal based on at least one force equation. At least one of said at least two input signals and/or at least one weighting parameter for the sensor fusion are determined on the basis of said detection of whether said at least one dynamic process is affecting the vehicle.

Abstract: A method, terminal and program for processing a speech signal, in which the speech signal is received over a network from a transmitting device, wherein the frequency components in the received speech signal are limited to a predetermined frequency range and the received speech signal has been filtered using a transmitter frequency response over the predetermined frequency range. The received speech signal is decoded. The decoded speech signal is filtered using a receiver frequency response which is complementary to the transmitter frequency response over the predetermined frequency range to thereby reduce distortion in the speech signal introduced over the predetermined frequency range by using said transmitter frequency response.

Abstract: In a mobile telephone or terminal (1) owned by a user a launcher program can be run. The launcher program then shows a menu list (3) of items that are available through the mobile telephone or terminal. The user can select any of the menu items by manual input, the program then starting the operation corresponding to or associated with the selected item, such as starting an application in the mobile telephone or terminal or opening/displaying an Internet page. Each time when the launcher program is started it checks whether new menu information on which said menu list is based is available and if available, it replaces or updates the menu information stored in the mobile telephone or terminal with said new menu information. It may also check whether a new version of the launcher program itself is available and if available, it can install the new version in the mobile telephone or terminal. For the updates, the mobile telephone or terminal may connect to an application server (31, 43) that has a storage in which current menu information and/or the latest version of the launcher program is/are stored.
