摘要： A conventional new video coding technology can provide a bitstream switching picture by encoding the bitstream switching picture into an I picture. However, an encoding efficiency is greatly reduced. As such, the new video coding technology does not provide an efficient bitstream switching function. Also, other advantages provided by a switching picture technology such as a random access, error durability, and a bitstream splicing are not provided. Provided is an apparatus for encoding a video bitstream including a base layer bitstream and an enhancement layer bitstream by encoding an enhancement layer picture of the enhancement layer bitstream, which is reproduced immediately after a base layer picture of the base layer bitstream is reproduced, into a non-switching pictures by interlayer prediction using a reference image generated by decoding a pre-encoded base layer picture or by motion prediction using another reference image generated by decoding a pre-encoded enhancement layer picture, and into a switching picture, which is decoded into the same image as the non-switching picture, by an interlayer prediction using the non-switching picture and a reference image generated by decoding a pre-encoded base layer picture, while the base layer picture is being reproduced.

摘要： The present invention relates to an apparatus and a method for vector descriptor representation and multimedia data retrieval, which can quantize a plurality of feature values described by a vector descriptor respectively, represent the quantized feature values in the form of bit or orthogonally transform the quantized bector feature values, and rearrange the feature values represented in the form of bit from the highest bit to the lowest bit or rearrange the transformed coefficient from low frequency to high frequency to represent the vector descriptor hierarchically. Moreover, when retrieving multimedia data, the present invention can code in variable length and store the rearranged feature values and the number of feature values which are input, inversely code only the feature values corresponding to the number of the feature values of the stored feature values, inversely arrange the inversely coded feature values to be restored to original feature values, inversely quantize the restored feature values, and compare the feature values restored by the inverse quantization with the feature values stored in a multimedia database to retrieve multimedia data.

The moving image encoder includes a base layer encoder receiving an original image and encoding the original image using a predetermined lossy encoding method and an enhancement layer encoder receiving an error image created by decoding the encoded original image and receiving the original image, and losslessly entropy-encoding an error component obtained by subtracting the original image from the image with error. Therefore, an original moving image can be scalabely and losslessly encoded/decoded based on conventional moving image encoding/decoding technologies, thereby offering moving image services with desired quality.
