    摘要： Techniques and tools are described for parameterization, signaling and use of in-loop filtering control information for interlaced video frames in video acceleration. For example, for a macroblock of an interlaced video frame, a decoder parameterizes in-loop filtering decisions as filter control information for video acceleration. The control information indicates filtering control decisions for external edges and internal edges of luma blocks and chroma blocks of the macroblock. The decoder makes the control information available to a video accelerator. The video accelerator retrieves the in-loop filtering control information. For a macroblock of an interlaced video frame, the video accelerator then performs in-loop filtering based at least in part on the control information.

    摘要： Techniques to perform fast motion estimation are described. An apparatus may comprise a motion estimator operative to receive as input a current frame and a reference frame from a digital video sequence. The motion estimator may generate and output a motion vector. The motion vector may represent a change in position between a current block of the current frame and a matching reference block of the reference frame. The motion estimator may utilize an enhanced block matching technique to perform block matching based on stationary and spatially proximate blocks. Other embodiments are described and claimed.

    摘要： The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof: which inhibit RNA-containing virus, particularly the hepatitis C virus (HCV). Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention. The present invention relates to novel antiviral compounds represented herein above, pharmaceutical compositions comprising such compounds, and methods for the treatment or prophylaxis of viral (particularly HCV) infection in a subject in need of such therapy with said compounds.
