    We address the problem of designing a TCP and IP (TCP/IP) based video on demand (VOD) system over a dedicated network based on standard internet protocols, i.e., transmission control protocol (TCP) and Internet protocol (IP). TCP and IP are usually referred together as TCP/IP. Despite of the general belief that TCP/IP is not suitable for real-time multimedia applications, after testing in a labora... View full abstract»

    A method is described for quickly and reliably detecting the VSB (vestigial side band) mode (2/4/8T/8/16) of a received VSB signal. This method can easily be implemented as a subsystem in a VSB receiver chip. Its performance at various signal to noise (S/N) ratios is analyzed and confirmed by simulation View full abstract»

    A perceptually based watermarking technique for an image is proposed. Based on the just-noticeable difference model in the wavelet domain, the watermark is inserted in the wavelet coefficients and its amplitudes are controlled by the wavelet coefficients so that watermark noise does not exceed the just-noticeable difference of each wavelet coefficient. Meanwhile, the order of inserting watermark n... View full abstract»

    To transmit an image over narrow bandwidth channels is an important issue in networks. We proposed a new progressive image transmission (PIT) method. We call it the fast reconstruction method (FRM). There are three techniques in this method. First, we use vector quantization (VQ) to compress the image. Then, we design the central sampling technique, and employ it to select the indices of the compr... View full abstract»

    Orthogonal frequency division multiplexing (OFDM) is a very popular scheme for signaling at high data rates over the time-dispersive multipath channel. We analyze the symbol error probability of OFDM on the shadowed multipath channels, and present the numerical results using the typical millimeter-wave channel parameter values. The two-ray model is used as a multipath channel model. Two types of O... View full abstract»

    Block matching can reduce temporal redundancies. It is an important scheme in video compression. So far, there have been many methods proposed for this scheme, such as fixed-sized block matching (FSBM), top-down variable-sized block matching (TDVSBM), and bottom-up variable-sized block matching (BUVSBM). In these methods, the blocks in each frame of a video must be square, and that is why some obj... View full abstract»
