264 wireless video communication,the bit-rate computation model and the standard deviation distortion model were analyzed,the relation between the quantization parameter of the encoding bit-rate and the intra frame refresh rate of the macro block was established,and a new ideal about the coding rate on the basis of general binomial computation model theory was put forward.

The market requirements for high-end LED display become far more rigid,especially on the visual refresh rate and grayscale levels.

After that we amend the modle to contain the quanzation parameter and intra rate so as to adjust the power dynamically.

Reading rates of normally sighted subjects were assessed and compared with the effects of window width,the number of gray levels,and phosphene refresh rate in the vision system.

paging and refreshing to the DRAM.

The spatial adjacent coding block s best mode is utilized to obtain the intra prediction of current coding block and the refresh technique is applied to reduce the error.

It is necessary to pull remote web pages periodically to refresh local copies of these pages on database in order to keep copies and source pages consistent, and which takes plenty of time and resources.

The most pressing matter at the moment is to update the current teaching system continuously,improve the abuses in traditional computer basis course teaching,focus on improving the teaching quality of the course by improving the content,teaching method,target cultivating,qualifications of t.
