摘要： In many video encoding bit rate control models such as TMN8 and RHO domain, the distortion D has been described as a uniform weighted distortion. According to the invention an approximated but still easy-to-use Laplacian distribution model is calculated for the quantisation step size adapta- tion in the macroblock layer bit rate control. The inventive bit rate control uses a pre-analysis step (LPPREA, HPPREA) that calculates the standard deviation of the input signal amplitudes in each macroblock in a Group of Frames. Using the corresponding standard deviation value determined in the pre-analysis step, in a motion estimation/compensation step (CQPEMB) the best mode for the P and B pictures and the ac- tual standard deviation of the prediction residual for the macroblocks are obtained, whereby a rate distortion optimi- sation processing using the Laplace distribution is per- formed. For I frames an intra prediction is carried out by which the best prediction mode and the actual standard de- viation of the prediction residual for the macroblocks are obtained, and a rate distortion optimisation processing us- ing the Laplace distribution is performed. Thereby for I and P frames the quantisation parameter for each macroblock is obtained and used in a corresponding quantisation that fol- lows transform (TRF1) of the prediction or motion estima- tion/compensation residual. For the B frames the bit rate control is carried out once again in an actual coding step, i.e. the quantisation parameter for a current macroblock is computed with the inventive improved TMN8 bit rate control using the best mode and the actual standard deviation obtained from the ME/MC stage.

摘要： Video equipment, e.g. for TV producers studios, need to display multiple channels of bit-streams simultaneously. Decoding multiple streams of high bit-rate videos is extremely computational intensive. An improved method for browsing an encoded frequency domain video sequence comprises steps of determining a spatial and/or temporal reduction level for browsing a video sequence, determining according to the determined reduction level frames, fields or parts of blocks or macroblocks to be skipped for decoding, and decoding the remaining data to a video with lower spatial and/or temporal resolution. The reduction may include adaptive partial coefficient decoding (23), motion vector truncation (24) and/or simplified deblocking filtering (25). The reduction of spatial resolution is advantageously performed in the frequency domain, so that the inverse quantization process and the iDCT processes require less computing.

摘要： The TMN8 model for ISO/IEC 144 96-10 AVC uses a frame-layer rate control and a macroblock-layer rate control. However, it is to difficult to distribute in the macroblock layer rate control the available bit budget between the texture coding and the overhead coding of the selected macro-block mode and motion vectors. For smoothing the visual quality, the inventive bit rate control uses a pre-analysis ρ-domain rate control model, thereby forming a mapping between quantisation parameter QP and p and a mapping between QP and distortion. A PID characteristic or filter is applied for controlling the distortion in the bit allocation. Advantageously, the computational complexity is low.

摘要： A common mode in video encoding skips the encoding and transmission of macroblocks that can be fully predicted. It requires however complex calculations to determine such blocks. A fast algorithm is disclosed that speeds up the process of skip mode decision by reducing the computations for transform, thus using a simplified transform (T simp ), and reducing computations for quantization (Q low ). The disclosed method for detecting Skip mode checks only few low frequency coefficients, without performing a full transform, and offsets for Luma and Chroma part are adaptively chosen to modify quantization parameters in detecting Skip mode, which can achieve a good trade-off in keeping both subjective and objective quality.
摘要翻译：视频编码中的共同模式跳过可以完全预测的宏块的编码和传输。然而，它需要复杂的计算来确定这样的块。公开了一种快速算法，其通过减少变换的计算来加速跳过模式决定的过程，从而使用简化的变换（T> simp ），并且减少量化的计算（Q < / SUB>）。所公开的用于检测跳跃模式的方法仅检测少数低频系数，而不执行全变换，并且自适应地选择亮度和色度部分的偏移量来修改检测跳跃模式中的量化参数，这可以实现两者的良好权衡主观客观品质。
