Abstract: A socket assembly includes a connecting base, comprising a signal port and a shielding structure. The shielding structure is disposed around a peripheral edge of the signal port. The plug assembly includes a connecting head. The connecting head includes a signal terminal and a ground component. The signal terminal and the ground component are disposed side by side. When the plug assembly is fixedly connected to the socket assembly, each connecting head extends into one connecting base, the signal terminal is conducted to the signal port, and the ground component is bonded to the shielding structure. In this application, the shielding structure of the connector is disposed around peripheral edges of the signal terminal and the signal port, and forms bonding with the ground component. This may effectively prevent a phenomenon of signal current return, avoids impact of crosstalk resonance, and improves signal transmission integrity of the connector.

Abstract: The present invention relates to the technical field of LED packaging, in particular to an easily-assembled COB lamp bead, a support for the lamp bead, a method for manufacturing the lamp bead and an easily-assembled LED module using the lamp bead. For the LED lamp bead provided by the present invention, as a first metal welding layer is provided on the bottom surface, it is just required to directly weld the lamp bead in a heat sink during assembling. Due to a power-taking slot formed of a positive plate and a negative plate in a matched manner, it is just required to insert one end of a driving circuit board, having a conductive terminal, into the slot during assembling. Hence, the whole assembling process is very simple, and both the efficiency and quality of assembling are effectively improved.

Abstract: Various embodiments provide methods and systems for streaming data that can facilitate streaming during bandwidth fluctuations in a manner that can enhance the user experience. In one aspect, a forward-shifting technique is utilized to buffer data that is to be streamed, e.g. an enhancement layer in a FGS stream. Various techniques can drop layers actively when bandwidth is constant. The saved bandwidth can then be used to pre-stream enhancement layer portions. In another aspect, a content-aware decision can be made as to how to drop enhancement layers when bandwidth decreases. During periods of decreasing bandwidth, if a video segment does not contain important content, the enhancement layers will be dropped to keep the forward-shifting of the enhancement layer unchanged. If the enhancement layer does contain important content, it will be transmitted later when bandwidth increases.

Abstract: A key frame extraction system and method for extracting key frames from a video based on motion analysis of frames within the video. Key frames are highlight frames that are effective in summarizing a video sequence. This allows a user to quickly find a desired spot in a video is long and contains differing subject matter. The key frame extraction system and method uses a triangle model of the motion energy in each frame and extracts key frames based on this model. More specifically, motion analysis is performed on the video frames in order to identify motion acceleration and motion deceleration points within the frames. A triangle model of motion then is constructed based on results of the motion analysis. The apex of the triangle represents a turning point between motion acceleration and motion deceleration. Frames corresponding to this apex are selected as key frames.
