Abstract: A video encoder with quality estimation is shown. The video encoder has a video compressor, a video reconstructor, a quality estimator, and an encoder top controller. The video compressor receives the source data of a video to generate compressed data. The video reconstructor is coupled to the video compressor for generation of playback-level data that is buffered for inter prediction by the video compressor, wherein the video reconstructor generates intermediate data and, based on the intermediate data, the video reconstructor generates playback-level data. The quality estimator is coupled to the video reconstructor to receive the intermediate data. Quality estimation is performed based on the intermediate data rather than the playback-level data. Based on the quality estimation result, the encoder top controller adjusts at least one video compression factor in real time.

Abstract: A lamp structure includes top case, a bottom case coupled to the top case, a lamp shade coupled to the bottom case, and an LED base board provided between the lamp shade and bottom case. The top case includes a hollow member formed on a top surface, a projecting member inside the hollow member such that a first tank is defined between the hollow member and the first projecting member, a first elastic ring inside the first projecting member, and a first latch member inserted in the first projecting member and configured to press the first elastic ring. The bottom case includes a second projecting member configured to cooperate with an interior surface of the bottom case to define a second tank, a second elastic ring inside the second projecting member, and a second latch member inserted in the second projecting member and configured to press the second elastic ring.

Abstract: The present invention provides a lamp structure, which uses the waterproof structure of the lamp to prevent external liquids from entering the lamp along the wire and hence avoiding risks in industrial safety caused by electrical leakage or sparks. The present invention uses the fixing member of the lamp to meet the installation requirements for different environments. In addition, by using the lens structure of the lamp, the lenses still can be fixed to the lamp after thermal expansion or shakes. Thereby, the risk of lens falloff can be reduced.
