A method of giving the user information on the operation of a portable device, and a portable device. In the method, an event that concerns the operation of the device and interests the user is detected by the control means of the device. If at least one silent alarm pattern producing a tactile sensation in the user is attached to the event, the user is given abstract information on the operation of the device by using at least one silent alarm pattern implemented with the alarm device and sensed by the user. Various alarm patterns differ from one another such that at least one alarm pattern characteristic sensed by the user varies. The characteristic can be the alarm pattern frequency, amplitude, changing rate of the amplitude, changing rate of the frequency or duration of the alarm pattern.

The invention primarily utilizes the average value of the rate-distortion cost of various coded macroblocks to forecast whether the current macroblock is coded into a skip macroblock by comparing the relation between the rate distortion cost of the skip mode of a macroblock to be coded and the average value; and then the possible interframe coding mode assemble of the current macroblock to be coded is forecasted through checking the mode assemble of the adjacent macroblocks coded on time and space; the forecast begins form the most possible coding mode by using occurrence frequency of various coded macroblocks interframe coding modes; and in the forecasting process, whether to stop the forecasting process of the interframe coding mode ahead of time is decided by comparing the relation between the rate distortion cost value and the average rate distortion cost value of the mode. Under the condition that mode ergodicity is not performed, the invention directly forecasts and obtains the possible interframe coding mode assemble of the current coding block by utilizing the statistic information of the macroblock coding mode and the correlation of the coding mode among macroblocks.
