[SHI DAN-DAN, HU MING, LUO SHI-JIN, XIA ZHI-LIANG, ZHANG ZHI] CN Aspects of the present invention provide a method for wafer warpage control. The method includes forming a filling structure in a slit opening on a wafer. Furthermore, the method includes measuring a warpage parameter of the wafer and determining a thermal distribution profile for adjusting the warpage parameter into a target range based on the warpage parameter. Then, the method includes performing a process with the determined thermal distribution profile, thereby adjusting the warpage parameter into the target range.

[Zhi Jin Xia, Zhi Bo Chen, Yu Wen Wu] In the case of packet loss during transmission over an error-prone transmission channel, some decoders may perform error concealment. In real-time systems, application decoders must handle the data loss alone and find out which data are missing. A special syntax within a packet-based framework is provided which is based on identifying and indicating the relationship between RTP packets and the application layer data they carry, before the packets are fed to the multi-layer application decoder. This helps the decoder to employ proper error concealment techniques in time, and prevents unnecessary processing in the decoder. A data stream comprises RTP packets containing application data of a multi-layer application, wherein an RTP packet (p2) contains two kinds of application layer information (NBf, NBn): one relating to the next RTP packet (p3), and one relating to the previous RTP packet (p1). In case of packet loss, the decoder can immediately determine the amount and type (VCLx) of missing data.

[XIA ZHI-JIN, CHEN ZHI-BO, WU YU-WEN] FR The invention is related to prediction of a lost or damaged block of an enhanced spatial layer frame. A method for predicting a lost or damaged block of an enhanced spatial layer frame (E5) comprises the steps of determining an adjuvant frame (E3) in the enhanced spatial layer (EL) by help of reference information from a lower spatial layer frame (B5) corresponding said enhanced spatial layer frame (E5), generating an information reduced block by help of said adjuvant frame (E3) and predicting the lost or damaged block by help of the information reduced block. The reference information of the corresponding lower spatial layer frame can be decoded independently from any lower spatial layer reference frame and the adjuvant enhanced spatial layer frame is already decoded. Thus, the computational effort is reduced. By generation of the information reduced block the prediction is made smoother which makes it less vivid and therefore less salient to a user.
