Abstract: The present invention provides an aripiprazole sustained-release microsphere and a preparation method therefor. The microsphere comprises aripiprazole and polylactide-glycolide. The microsphere is of a spherical reticular skeleton structure, with reticular micropores distributed in the spherical surface, and aripiprazole filled in the micropores. The average particle diameter of the microsphere is less than 20 ?m, and is suitable for a 5 gauge needle. The content of aripiprazole is 65%-80% of the total weight of the microsphere.

Abstract: Disclosed are a display apparatus and a method for displaying a user interface. In response to a preset instruction, the display apparatus acquires local images to generate a local video stream, plays a local video picture, and displays a graphic element for identifying a preset expected position in a floating layer above the local video picture. When the moving target exists in the local video picture and an offset of a target position of the moving target in the local video picture relative to the expected position is greater than a preset threshold value, a prompt control for guiding the moving target to move to the expected position is presented in the floating layer above the local video picture according to the offset of the target position relative to the expected position.

Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for evaluating video quality. In the embodiments of the present invention, a method in the prior art that the video quality is determined only according to the number of lost packets and a packet loss rate is modified, and the location of the most important lost packet is determined by analyzing the influence of the lost packet on other packets, and a damage degree or degree of intactness of the video frame is determined according to the most important lost packets, so as to determine the quality of the video frame. The method greatly improves the precision for evaluating the video quality.

Abstract: The present disclosure provides a method and system for splicing an advertisement, a splicer, and a head end device. The method includes: performing real-time transport protocol encapsulation processing on coded video data, to obtain at least one of a real-time transport protocol packet and a real-time transport protocol control protocol packet; and carrying splice information in the obtained real-time transport protocol packet or real-time transport protocol control protocol packet, and sending the real-time transport protocol packet or real-time transport protocol control protocol packet to a splicer, so that the splicer splices a received targeted advertisement into an advertisement avail of the video data according to the splice information in the received real-time transport protocol packet or real-time transport protocol control protocol packet.
