Bandwidth utilization within a cellular network is increase by reducing the amount of traffic to be transmitted, in particularly in traffic that has already been compressed. An encoded signal that comprises an umber of frame signals (or simply frames) is received and each frame is classified in accordance with one or more pre-defined characterization criterion. The characterization can include identifying the frames as speech type signals, such as voice signals or noise signal. Voice signal frames may be further characterized as a stationary frames (where the voice signal is essentially at a constant level), as a transition frame between phonemes, and the like. A noise type of frame may be further characterized as a silence frame, a background noise and the like. Video frame types can be characterized as a frame with a rapid / slow change in respect to the preceding frame, a frame with a rapid / slow change in respect to pixels in that frame, and the like. Depending on the classification of each frame, the encoded signal may be formatted and be replaced by a corresponding representation signal, wherein the number of bits comprised in a plurality of the formatted signals, is less than the number of bits comprised in the received encoded signal. Consequently, a formatted frame signal may be represented by a selected corresponding representation signal, or by a number of selected a corresponding representation signals which correspond to the sub-frame signals, and when taken together, carry the information required for the regeneration or reconstruction of the entire encoded frame signal.

The invention discloses a method for allocating the dynamic bandwidth of an ether passive optical network, which comprises a predictor and a dynamic bandwidth allocation rule (PQ-DBA algorithms) capable of upgrading and adjusting the service quality. The predictor is mainly used for predicting the action of terminal users and the packing quantity of various services with a line pipe scheduling predictor formed by recursion type artificial neural network and an extension recursion least square method learning rule. The method builds better service quality traffic guarantee with the bandwidth which is allocated by an original light terminal unit according to an optic main control terminal and the user packets which are transmitted from the high priority to the low priority.

The present application relates to an image compression method. A computer device divides an image to be compressed into multiple compression units; each compression unit includes at least two sub-blocks; and then, based on a preset compressed data format, the compressed data of each compression unit is respectively obtained ; Wherein, the compressed data includes the reference pixel value of the compression unit, the first pixel associated data, the second pixel associated data, the sub-block position where the reference pixel value of the compression unit is located, and the pixel position where the reference pixel value of each sub-block is located; The first pixel correlation data is used to represent the pixel relationship between the compression unit and each sub-block in the compression unit, and the second pixel correlation data is used to represent the pixel relationship in each sub-block. By adopting the above method, the compression ratio of the image to be compressed can be improved, the bandwidth utilization efficiency can be improved, and the time delay for reading compressed data can be reduced; information distortion caused by the compression of the image to be compressed can be avoided.
