Information provider apparatus enabling selective playing of multimedia information by interactive input based on displayed hypertext information

Abstract: An information provider apparatus, enabling a user to employ hyperlink selection from a displayed hypertext data page to obtain and play the contents of specific sets of multimedia data which are held in a data storage device, executes control of playing of a set (101) based upon elapsed frame numbers of a video clip (102) which forms part of the set, in conjunction with scenario data which have been predetermined for the set. The apparatus can be used in a network in which users of various client terminals can access multimedia data stored at a server computer, or can exchange electronic mail items each consisting of a set of multimedia data (101) in conjunction with corresponding scenario data, or can post messages on a "notice board" hypertext page at a server computer, each message consisting of a set of multimedia data and corresponding scenario data, with other users of the network being able to access the posted messages by browsing selection.

Study of interface roughness dependence of electron mobility in Si inversion layers using the Monte Carlo method

Abstract: The electron mobility in the inversion layer of a metal–oxide semiconductor field effect transistor formed on the (100) silicon surface is calculated by using a Monte Carlo approach which takes into account size quantization, acoustic phonon scattering, intervalley phonon scattering and surface roughness scattering. Degeneracy is also considered because it is important at higher normal effective fields (high gate voltages). The main emphasis is placed on the influence of the specific autocovariance function, used to describe the surface roughness, on the electron mobility. Here we compare the mobilities obtained using exponential and Gaussian autocovariance functions. It is found that the electron mobility calculated with roughness scattering rates based on the exponential function shows good agreement with experiments. The effect of the degeneracy and screening on the roughness scattering is also discussed.

Multilayer microstrip wiring board with a semiconductor device mounted thereon via bumps

Abstract: A semiconductor device includes a microstrip wiring board. The microstrip wiring board includes a substrate having a main surface, a ground conductor extending on the main surface of the substrate, a dielectric film extending on the ground conductor, and a metal wiring line extending on the dielectric film. A semiconductor chip is connected to the microstrip wiring board via a bump.

Picture coding apparatus and picture decoding apparatus

Abstract: A picture coding apparatus (10) which generates a stream so as to be able to decode a picture by obtaining a picture parameter set necessary for decoding the picture even at the time of trick-play, the apparatus including: a slice coding unit (11) which codes the picture and generates coded data; a picture parameter set (PPS) generation unit (13) which generates sequence parameter set (SPS); a PPS generation unit (16) which generates the PPS; and an access unit (AU) determination unit 17 which stores pieces of coded data respectively into access units of a random access unit (RAU) and stores the SPS into a first AU, and stores the PPS into the first AU or into the AU in which one piece of the coded data that refers to the PPS is stored.

Data accessing method, device in which the data accessing method is executed and recording medium

Abstract: [OBJECT] To guarantee a data transfer rate irrespective of a performance of a memory card [SOLVING MEANS] A parameter to show a data transfer efficiency is previously recorded in a recording medium 101 in which data is written per data size that can be increased and decreased stepwise and the data transfer efficiency is variable in accordance with the data size Next, a data accessing apparatus 105 issues a parameter acquisition command to the recording medium 101 The recording medium 101 which received the parameter acquisition command transmits the parameter The data accessing apparatus 105 collates the received parameter with the data transfer efficiency required in the data to be written/read to thereby select an optimum data size Then, the data accessing apparatus 105 writes/reads the data to the recording medium 101 based on the selected optimum data size
