Some authentication is to be performed during the transmission of data via insecure networks. Data encryption is one of the(More)
We proposed an adaptive MPEG-2/4 video encoding scheme suited for a dynamic networking environment. Conventional approaches use large quantization scales to reduce the transmission bit rate in low bandwidth situations. However, the larger quantization scale degrades the image quality severely. We believe not only that adaptive quantization should be used(More)
