The invention relates to a wire material of an aluminium alloy wire, and a preparation method thereof. An aluminium alloy wire with high strength and high electrical conductivity which has a high fiber texture degree is obtained through an ultra-low temperature rapid drawing process, and the aluminium alloy wire has a fiber texture degree of more than 60%, a tensile strength of more than 130Mpa, and an electrical conductivity of more than 63% IACS. According to the invention, a micro alloying design is performed by using composites of ferrum, scandium and the like which can form Al3Me type eutectic compound particles; a certain fiber texture is obtained through a drawing process by controlling a continuous casting and rolling process; the fiber texture degree is greatly increased and the distortion caused by room temperature deformation is reduced through the ultra-low temperature rapid drawing process; and the texture orientation and the texture degree of the aluminium wire after the drawing process are adjusted through an annealing treatment, the drawing stress is relaxed, the plasticity of the wire is recovered, the resistance of the wire is reduced and the electrical conductivity of the wire is increased. Compared with the prior art, the aluminium alloy wire and the preparation method of the invention can control the deformation process in micro alloying conditions to greatly increase the strength and the electrical conductivity of the wire.

The invention provides a method and a device for quickly selecting high efficiency video coding (HEVC) intra prediction mode on basis of texture characteristics. A texture direction statistical histogram is generated by determining the texture amplitude and the texture direction of each element of an edge texture figure of a to-be-predicted unit (PU), so that the strong texture direction of the PU is judged; and when the PU has the strong texture direction which is matched with a prediction mode direction of any adjacent module, the strong texture direction serves as the final prediction mode direction. By the method and the device, the search times are reduced, the calculation time of mode selection is effectively reduced and the speed of mode selection is obviously increased on the premise of guaranteeing the coding quality.
