    摘要： A method, a device, and a system for real-time publish subscribe (RTPS) discovery based on a distributed hash table (DHT) are provided. The method for RTPS discovery based on a DHT includes: registering, by a participant peer of participants, the participants in a distributed hash table (DHT) of an overlay network; obtaining location information on relative participants to be discovered from the DHT; sharing information on entities of the relative participants by exchanging a discovery message with the participant peer based on the location information on the obtained relative participants; and performing handshaking between the entities of the participants and the entities of the relative participants. Therefore, the exemplary embodiments of the present invention can rapidly and efficiently perform the discover of the participants based on the DHT.

    摘要： The present invention relates to a half-pel motion estimation method. The calculation object half-pel, which is in the block of the previous or next reference frame, is not estimated additionally for each block of the current frame divided into blocks of a predetermined size. The present invention suggests an algorithm that can perform half-pel search only with a SAD value used in integer-pel search and a random variable for correcting errors. Since the present invention does not have to generate half-pel for motion estimation, the calculation amount is amazingly reduced and the calculation time is reduced.

    摘要翻译： 半像素运动估计方法技术领域本发明涉及半像素运动估计方法。 在前一帧或下一个参考帧的块中的计算对象半像素对于被划分为预定大小的块的当前帧的每个块不附加估计。 本发明提出一种算法，它只能使用在整数像素搜索中使用的SAD值和用于校正错误的随机变量来执行半像素搜索。 由于本发明不需要生成用于运动估计的半像素，因此计算量惊人地减少并且计算时间减少。
