    摘要: A context reduced last transform (CRLT) coding technique which enhances parallel context processing, such as utilized in JCTVC-D262, to reduce complexity by reducing the number of context models using for coding the position of the last significant transform coefficient. Selected context models are removed and additional bins are shared which reduce the number of contexts required. In one benchmark test for YUV 4:2:0 video, the number of context models were reduced from 120 for the proposed entropy encoding of JCTVC-D262 test model HM 2.0, versus 82 context models required for CRLT coding.

    摘要: A fast implementation context selection of a significance map includes caching the significance of each coefficient in a buffer, storing an extended significance map in an extended buffer and updating the extended significance map after the significance of a transform coefficient is determined by the encoder or the decoder.

    摘要: This invention is a projector headlight that, while offering dual beam patterns, boasts a 100% utilization of the light emitted from a light source by one of the following methods: (1) employing a reflective cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern, (2) using reversible cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern with no moving part involved, (3) utilizing a selective light-filter cutoff means to selectively reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern without making use of any moving part, (4) using a low-beam light-emitting subassembly and a high-beam light-emitting subassembly that are separated by partition means to achieve dual beam patterns with no moving part, or (5) adopting a low-beam light-emitting subassembly in low-beam pattern and a high-beam light-emitting subassembly in high-beam pattern without any moving part.
