    Abstract: Disclosed are encoding and decoding apparatuses and methods based on variable sub-band analysis. The encoding method based on variable sub-band analysis includes: generating down-mixed signals out of inputted multiple audio objects and encoding the down-mixed signals; transforming the multiple audio objects into a frequency domain to thereby produce frequency-domain signals; dividing a sub-band of the frequency-domain signals into variable sub-bands based on a characteristic of the sub-band and generating variable sub-band information including information on the variable sub- bands; generating parameter information used for recovering the down-mixed signals based on the variable sub-bands; and encoding the variable sub-band information and the parameter information.

    Abstract: Disclosed is a stereoscopic/multiview three-dimensional video processing system and its method. In the present invention, stereoscopic/multiview three-dimensional video data having a plurality of images at the same time are coded into a plurality of elementary streams. The plural elementary streams output at the same time are multiplexed according to the user's selected display mode to generate a single elementary stream. After packetization of the single elementary stream continuously generated, information about the stereoscopic/multiview three-dimensional video multiplexing method and the selected display mode information are added to the packet header of the stream. Then the packetized elementary stream is sent to the image reproducer or stored in storage media. The present invention multiplexes the multi-channel elementary streams having the same temporal and spatial information, thereby minimizing the overlapping header information, and performs streaming of data suitable for the user's demand and the user system environments.

    Abstract: Provided is a method for searching for an optimal coder suitable to a dual stream transmission method of a DTV transceiving apparatus, and an encoder and a decoder employing the optimal coder searching method. The optimal coder searching method includes the steps of: a) determining a mixed pattern of normal stream and robust stream; b) determining a trellis structure of the robust stream which is applied to the mixed pattern based on how coders are connected; c) forming a dual stream trellis by mixing a trellis of the normal stream, which is a normal stream trellis, and a trellis of the robust stream, which is a robust stream trellis; d) computing a free distance at departing points of the dual stream trellis structure based on a dual stream free distance computation termination condition; and e) determining the optimal coder based on the free distance.

    Abstract: In a channel equalizer applicable to a digital television receiver, a forward filter and a backward filter perform filtering to an input signal and a predetermined signal. A Viterbi decoder corrects errors during a transmission procedure in a blind mode. A training symbol storing block stores training symbols. An output signal of the Viterbi decoder and symbols are provided to the backward filter in accordance with a blind mode or a training mode. A Kalman gain is calculated in a Kalman gain calculating block and an error signal is calculated by comparing an equalized signal, symbols, and the output signal of the Viterbi decoder with one another. A tap coefficient is updated by using the calculated error signal and the Kalman gain.
