摘要： A variable length encoding (VLE) device of an image compression system is suitable for encoding transformed and quantized block image signals. The VLE device includes a plurality of encoding modules, for performing VLE on the block image signals; and a selection module (VLE module start controller), for selecting a number of the encoding modules in turn to encode the block image signals. The encoding modules are configured for parallel processing, and an operating frequency of each of the encoding modules is a fractional frequency of a throughput rate of the image compression system. The VLE device is not affected by the time consumed by the VLE in the image compression process, and enables the entire image compression system to operate as desired and achieve the required throughput rate.

摘要： A wideband planar dipole antenna comprises a substrate and two antenna bodies. Metal conductor is printed on the single surface/double surfaces of the substrate to form the antenna bodies. With a dipole antenna architecture, the antenna bodies are manufactured as loop structures similar to concentric circles. The loop structures can be of rectangular or circular shapes. Loops of metal conductors with different lengths resonate to obtain similar but different frequencies. Each path of every antenna body can be finally connected with a metal conductor sheet capable of changing to any shape. Every path can interfere with adjacent paths to achieve the wideband effect. An asymmetric mechanism can be added in one of the antenna bodies. Besides letting the antenna have the resonance effect of the symmetric part, the loop path at the signal source can also be increased to enhance the receiving performance of the antenna.

摘要： A method for reducing memory size and amount of data accessed of a buffered-frame storage device in a video codec is provided. It is applicable to a codec compliant with a video encoding and decoding standard. When a block is decompressed, the block is stored in the buffered-frame storage device using either compression data or reconstructed data based on its encoded mode and the positions of its reference frames, or based on a topological pattern and a pre-determined memory capacity constraint. With this method, not only the memory size of the buffered-frame storage device, but also the computational complexity requirement for decoding compression data of reference frames is reduced. The present invention compromises among the buffered-frame memory size, amount of data accessed, and computational complexity requirement.
摘要翻译：提供了一种用于减少视频编解码器中的缓冲帧存储设备的存储器大小和数据量的方法。它适用于符合视频编码和解码标准的编解码器。当块被解压缩时，使用压缩数据或基于其编码模式的重建数据或其参考帧的位置，或者基于拓扑模式和预定的存储容量，将块存储在缓冲帧存储设备中约束。利用这种方法，不仅缓冲帧存储设备的存储器大小，还降低了对参考帧的压缩数据进行解码的计算复杂度要求。本发明在缓冲帧存储器大小，访问数据量和计算复杂度要求之间妥协。
