Rate control (RC) techniques play an important role for interactive video coding applications, especially in video streaming applications with bandwidth constraints. In this paper we propose a new BU-level rate control algorithm with ROI support and the associated architecture for H.264 and AVS by exploiting a new predictor model to predict the MAD value and target bits for hardware realization. The...
This demo proposes a dynamic quality-scalable H.264 video encoder that has been published in ISSCC2007 [8]. Exploiting parameterized algorithms for motion estimation and intra prediction, the proposed design can dynamically configure the encoding modes with the design trade-off between power consumption and video quality for various video applications.
Rate control (RC) techniques play an important role for interactive video coding applications, especially in video streaming applications with bandwidth constraints. Among the RC algorithms in H.264 reference software JM, the basic unit (BU)-level RC algorithm achieves better video quality than frame-level one. However, the inherent sequential processing in H.264 BU-level RC algorithm makes it difficult...
Rate control plays an important role for video coding especially in video streaming applications with bandwidth constraints. The inherent sequential processing in H.264 basic unit (BU) level rate control algorithm makes it hard to be realized in a pipelined H.264 hardware encoder without increasing the processing latency. In this paper we propose a new H.264 BU-level rate control algorithm facilitating...
High resolution paleoceanographic proxy records from a deep-sea core in the northern South China Sea (SCS) and palynological records from a lake core in central Taiwan have been measured for the last 25 kyr. The variations in these proxy records are interpreted in terms of the past variation in the Asian monsoons. The two consistent and complementary records suggest that the East Asian monsoon system...
