摘要： An MPEG-4 system with error concealment is provided for video service under the network with packet loss. The MPEG-4 system includes an encoder and a decoder. The encoder uses an intra-refreshment technique is used to make coded bitstream more robust against noise in order to stop error propagation. The rate-distortion optimization criterion is also introduced to adaptively update in synchronization with intra-coded blocks adaptively based on the true network condition with minimal overhead. The Lagrange multiplier is modified to achieve the best rate-distortion balance. In addition, a decoder loop is used in the encoder and is synchronized with the true decoder to achieve the best performance and avoid mismatch with the decoder used in the MPEG-4 system. The decoder is able to achieve resilient decoding from any kind of noise and enhance the reconstructed image quality with spatial and temporal hybrid concealment method. The result shows that a 3.65-9.71 dB further improvement on peak-signal-to-noise-ratio (PSNR) can be achieved in comparison with the existing methods that adopt spatial copy and zero motion concealment in decoding.

摘要： A waterproof-breathable structure for a flashlight includes a housing and a ventilative plug. The housing is penetrated by a hole with one or more chamfered segments, and the ventilative plug has an outer diameter greater than the hole to be closely fit therein. The ventilative plug has a capping portion, an abutting flange extending from an outer part thereof, and a rim extending from an inner part thereof. Thereby, inner pressure generated in the flashlight due to battery oxidation over time is allowed to escape through an interval formed between an inward retracted periphery of the ventilative plug and the chamfered segments formed at the inner periphery of the housing hole, while the ventilative plug closely fit in the hole of the housing of the flashlight serves to effectively prevent external moisture from incursion.
