Abstract
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.
