Abstract: There are provided an apparatus and a method for encoding an image for a mobile telecommunication handset. The image is divided into the stripe blocks and the number of the phase of wavelet transform is determined depending on the size of the image. The divided image stripe block is wavelet-transformed depending to the determined number of the phase. The wavelet-transformed high-frequency components is granular-quantized and the wavelet-transformed low-frequency components is DPCM-encoded. Thus, computing load and memory capacity can be lessened, maintaining the image of good quality in the mobile telecommunication handset.

Abstract: A connection procedure for finding by rearrangement a path for multirate, multicast traffic through an SDH cross-connect with subnetwork connection protection. If no free path for a new payload through the SDH switching hardware is available, the switching procedure looks for a path that is adequate and blocked by the least existing payload capacity. If the hunt is successful, the procedure rearranges the existing connections to make possible a path for the new payload. The procedure does not interrupt the existing connections; thus it is a "hitless" procedure. Connections for existing payloads that must be moved to make way for the new payload are queued and the connection procedure is applied recursively, to each in turn, until the queue is empty.
