摘要： A fast parallel 2-D discrete casing transform, DCT, device capable of performing a fast 2-D DCT by significantly reducing the number of multiplications during the implementation of the 2-D DCT. N.times.N 2-D input data is re-arranged into N groups so as to be the same as the kernel of a cosine function in order to transform a multiplying form of the cosine function (as the kernel of a 2-D DCT) into a summation form. Then, the first summations and first subtractions are carried out on the re-arranged data, thereby generating first computed data. Then, N 1-D DCT's are carried out on the first computed data. Finally, the 2-D DCT data is generated by carrying out a shifting process after performing additions and subtractions on the 1-D DCT data in log.sub.2 N stages.

摘要： Provided is an apparatus for and a method of transcoding video, in which, in the transmission of a compressed video, the compressed video is transcoded into multiple descriptions in an error prone environment and is transcoded into a single description in an lower error or errorless environment. Video transcoder includes a decoding unit, a single description/multiple description determining unit, and a transcoding unit. The decoding unit decodes a compressed video to generate video header, a motion vector, and a DCT (discrete cosine transform) coefficient for each frame. The single description/multiple description determining unit determines whether to perform transcoding into a single description or multiple descriptions based on the possibility of errors occurring in a transmission channel of the compressed video. The transcoding unit performs transcoding into the single description by coding the DCT coefficient together with the video header and the motion vector when the single description/multiple description determining unit determines to perform transcoding into the single description and performs transcoding into the multiple descriptions by dividing the DCT coefficient into a plurality of DCT coefficients and coding each of the DCT coefficients together with the video header and the motion vector when the single description/multiple description determining unit determines to perform transcoding into the multiple descriptions.

摘要： An apparatus for and a method of transcoding data in a first format, for example, MPEG (moving picture experts group)-2 data into data in a second format, for example, H.264 data. The apparatus may include a scaling dequantization unit, a coefficient transform unit, and/or a scaling quantization unit. The scaling dequantization unit may dequantize the data in the first format (e.g., MPEG-2 data) to generate a DCT (discrete cosine transform) coefficient. The coefficient transform unit may approximate a 4x4 second data format (e.g., H.264) integer transform matrix to a 4x4 DCT matrix and transforms the DCT coefficient into an integer transform coefficient using the approximated 4x4 DCT matrix. The scaling quantization unit may quantize the integer transform coefficient to generate the data in the second format (e.g., H.264 data).
