The present disclosure provides a dynamic tone mapping method, a mobile terminal, and a computer readable storage medium. The method includes: acquiring maximum brightness information and average brightness information of a frame to be displayed on the display terminal; inquiring a tone mapping data group respectively corresponding to the maximum brightness information and the average brightness information in a preset tone mapping look-up table; and calling the tone mapping data group and transforming a tone mapping on the frame to be displayed on the display terminal. The present disclosure can change the tone mapping data group for transforming the tone mapping in real time according to the maximum brightness information and the average brightness information of the frame monitored in real time, to reasonably utilize the hardware dynamic range and present a better HDR effect.

Disclosed are a backlight brightness adjustment method and apparatus. The backlight brightness adjustment method includes the following steps: dividing a backlight area of a liquid crystal display (LCD) into multiple sub-areas, acquiring maximum pixel brightness M of each sub-area, and acquiring average pixel brightness A according to the maximum pixel brightness M; classifying the brightness into multiple brightness ranges, and separately adjusting duty cycles and drive currents of a backlight source in different brightness ranges according to the average pixel brightness A and the maximum pixel brightness M; determining, according to the maximum pixel brightness M of each sub-area, a brightness range of the sub-area, and acquiring an adjusted duty cycle and drive current that correspond to the brightness range of each sub-area; and correspondingly controlling illumination brightness of each sub-area by using the adjusted duty cycle and drive current. The present invention improves contrast of an LCD.

The present invention provides a method for controlling generation of routing information, a method for generating routing information, and apparatuses thereof. When it is detected that a virtual machine is migrated out of or migrated into a data center, a subnet to which the virtual machine belongs is determined, a route control identifier for adjusting routing information of a virtual machine that belongs to the subnet and is in the data center is determined, and the route control identifier is sent to the data center, so that the data center adjusts, according to the route control identifier, routing information of the virtual machine that belongs to the subnet and is in the data center. In this way, generation of many host routes in data centers when a virtual machine is migrated across the data centers is prevented.

The present invention relates to network coding and discloses a method, an apparatus, and a system for random linear network coding to prevent the complicated and time-consuming process of network coding. The coding method for random linear network includes: splitting original data into at least two data blocks sequentially; determining at least two coefficient groups, wherein a length of each coefficient group is the same as the number of the data blocks, and the coefficient group comprises two elements; performing a bitwise-AND operation on the data blocks and coefficients corresponding to the data blocks to obtain code blocks; and performing a bitwise-XOR operation between the code blocks to obtain a code packet. The present invention is applicable to the network coding which requires a high efficiency of coding.
