On the base of Analyzing DM6446 different booting ways and UBL and U-Boot source code operating mechanism, Successfully transplanted UBL and U-boot to the intelligent video surveillance hardware platform, thus realized hardware platform's booting and operating system's startup. We described in detail the procedure and key technologies of transplanting U-Boot to the DM6446 platform. It is helpful to...
The paper optimizes AVS key coding algorithm, and designs high coding efficiency and high coding quality AVS encoder XAVS based on x86 platform. It supports IPPP, IBBP structure, films on a variety of formats of media sources to AVS compression, rate control, rate distortion optimization, and packaged into the standard TS stream. The experiment results show that subjective quality of XAVS is better...
The paper optimizes AVS key coding algorithm, and designs high coding efficiency and high coding quality AVS encoder XAVS based on x86 platform. The coding system supports a variety of search options, scene change detection, rate distortion optimization (RDO) and rate control algorithms. The experiment results show that subjective quality of XAVS is better than that of rm52j; In the case of the same...
