Patent number: 8711927Abstract: An embodiment of the present disclosure relates to system comprises an encoding device. Said encoding device comprises a compression unit, a quantizer, a bit estimator, a bit rate encoder and a variable length encoder. An embodiment also is a method of encoding. Said method estimates a number of bits to encode a macroblock after compressing the data stream. Then the estimated bit encoded by a bit rate encoder and further quantized by the quantizer to get the final encoded bit stream. The number of bits required to encode a macroblock is estimated after the quantization process and before the encoding process. The macroblock bit estimator estimates the number of bits required to encode a particular macroblock depending on the quantized AC coefficients of that macroblock and the quantized AC coefficients of the neighboring frames normalized at a macroblock level.Type: GrantFiled: December 11, 2009Date of Patent: April 29, 2014Assignees: STMicroelectronics International N.V., STMicroelectronics S.r.l.Inventors: Megha Agarwal, Sumit Johar, Kaushik Saha, Emiliano Mario Piccinelli

Patent number: 8395991Abstract: Systems and methods are for implementing a NSV2SV converter that converts a non-scalable video signal to a scalable video signal. In an implementation, a non-scalable video signal encoded in H.264/AVC standard is decoded and segmented into spatial data and motion data. The spatial data is resized into a desired resolution by down-sampling the spatial data. The motion data is also resized in every layer, except in the top layer, of a scalable video coding (SVC) encoder by using an appropriate measure. Further, the motion data is refined based on the resized spatial data in every layer of the SVC encoder. The refined motion data and the down-sampled spatial data are then transformed and entropy encoded in the SVC standard in every layer. The SVC encoded output from every layer is multiplexed to produce a scalable video signal.Type: GrantFiled: September 14, 2009Date of Patent: March 12, 2013Assignees: STMicroelectronics PVT.

Patent number: 7301999Abstract: Digital signals are converted between a first and second format by a conversion process including generating coefficients representing the digital signals. The coefficients may be discrete cosine transform coefficient generated during encoding/transcoding of MPEG signals. The coefficients are subject to quantization by generating a dither signal that is added to the coefficients before quantization to generate a quantized signal. Preferably, each coefficient is first subject to a first quantization in the absence of any dither signal added to generate an undithered quantized coefficient. If the undithered quantized signal is equal to zero the undithered quantized coefficient is taken as the output quantized signal. If the undithered quantized coefficient is different from zero, the dither signal is added and the dithered coefficient thus obtained is subject to quantization to generate the output quantized signal.Type: GrantFiled: January 14, 2004Date of Patent: November 27, 2007Assignee: STMicroelectronics S.r.l.Inventors: Gianluca Filippini, Emiliano Mario Piccinelli, Danilo Pietro Pau
