The plurality of portions of multimedia data divided into the plurality of screen regions are compressed with different compression rates.

Abstract: The present invention relates to a manufacturing method of polyaspartic acid. More particularly, the present invention relates to a manufacturing method of polyaspartic acid comprising steps of carrying out condensation polymerization of maleic anhydride and ammonia in the presence of a polar solvent without active hydrogen to give polysuccinimide and hydrolyzing the resulting polysuccinimide to obtain polyaspartic acid. Specifically, the present invention is characterized in that the quality of the synthetic product, polysuccinimide and polyaspartic acid, is improved by minimizing the decomposition and the degradation of the maleic acid during the process of the polymerization resulted from the introduction of substituent to maleic acid.

Abstract: A method for HARQ reordering in Enhanced Uplink Dedicated Channel of WCDMA system includes following steps: locating the soft combination buffer in the Node B and the reordering buffer in the SRNC; locating the HARQ entity in the Node B; locating the reordering queue distribution entity, the reordering entity and the disassembly entity in the SRNC. This invention adopts the separation technology of the soft combination buffer and the reordering buffer, the separation model can not only ensure the diversity gain, but also reduce the receiving delay and save the buffer space. Three mechanisms (timer mechanism, window mechanism and SBI mechanism) are proposed to prevent the blocking of the reordering buffer, which degrades the blocking to the least level, improves the receiving efficiency and the system performance. Aiming at the SBI mechanism, the invention proposes the new DCH data frame structure on the Iub interface and the Iur interface.

Abstract: A method for the terminal-to-terminal direct communication in the TDMA mobile communication system includes the following steps when making use of the uplink timeslots of the normal communication: in the initial phase, a sender still transmits a signal to a receiver according to its transmission timing for the normal communication; the receiver detects signals of its surrounding terminals that are in normal communication, and selects one with the strongest power as the strongest interference signal; the receiver detects the signal from the sender and compares the arrival time of the sender's signal with that of the strongest interference signal, and thereby obtains an adjustment control instruction for the sender, and feedback the control instruction to the sender; the sender adjusts its transmission timing according to the control instruction that it receives. This invention solves the synchronization problem of the direct communication in the TDD mobile communication system.

Abstract: A method of performing an inter-RAT measurement for a handover from NB-TDD to GSM is provided. A UE, as it moves from an NB-TDD Node B to a GSM cell, receives a measurement control message from the NB-TDD Node B. The UE then measures the strength of a signal received from the GSM cell and verifies its identification for a predetermined measuring time. If the UE successfully verifies the identification of the GSM cell for the measuring time, it reports the signal strength measurement and the verified GSM cell identification to the NB-TDD Node B. If the UE fails to verify the identification of the GSM cell for the measuring time, it reports only the signal strength measurement to the NB-TDD Node B.

Abstract: A method and apparatus for providing a service based on multiple data rates using scalability of a multimedia CODEC in an asynchronous code division multiple access (CDMA) communication system, which provides a multimedia broadcast and multicast service (MBMS). An entire cell area is divided into a first area and a second area. Specific data is separated into first data and second data. The first data is transmitted to the first area, and the second data is transmitted to the second area. A first electric power controller controls electric power for the first data. A second electric power controller controls electric power for the second data. A user equipment (UE) located in the second area receives the first data and the second data. The UE located in the second area combines the first data and the second data, thereby generating one data item.

Abstract: An ion implanter and an ion implanting method compatible for both positive and negative ions. The ion implanter has an ion extractor and a mass analyzer for deflecting ions, having one of a positive or negative charged state, in a predetermined direction regardless of the charged state of the ions. A polarity converter changes the flux direction of a magnetic field in the mass analyzer according to the charged state of the ions. Thus, shallow and deep impurity layers can be formed into wafers without changing ion implanters, such that BF.sup.+ as well as B.sup.+ or P.sup.+ can be implanted with a single ion implanter. As a result, the product yield of a semiconductor device can be improved.
