摘要： An audio rate converter converts a sampling rate for audio data into a fixed rate. In the audio rate converter, an input audio data DAin at a sampling rate of PFS (48 kHz.+-.x%) are stored in the memory in accordance with a write address WAD which is synchronized with the rate PFS. Audio data are read from the memory in accordance with a read address RAD which is synchronized with a rate FS (48 kHz), and coefficient data determined based on a sampling point in output audio data are read from a ROM table in accordance with a read address Coef.AD which is synchronized with the rate FS. A data arithmetic and logic circuit performs multiplying and adding operations using these data in order to produce the output audio data DAout. If the sampling rate PFS at which the input audio data are provided changes, the audio rate converter can provide the output audio data DAout at the fixed sampling rate FS.

摘要： A digital video signal is transmitted via a communication system which can transmit digital data through an asynchronous communication line (ATM communication line) or the like and, at the same time, voice information for the working communication and information such as computer information are transmitted by using the communication system. The user of a first data transmitting apparatus sets up the character data etc. for communication on the terminal. The set character data is multiplexed in the predetermined transmission packet together with the audio and video data output from the VTR device and transmitted via an ATM communication line 2 to a second data transmitting apparatus. In the second data transmitting apparatus, the character data is demultiplexed from the transmission packet and displayed on for example the display device of the personal computer. In place of the character information, also voice information can be transmitted by a telephone set. In this way, the users of both data transmitting apparatuses transmit and receive the working communication information by using the communication line for transmitting the digital video signal.

摘要： In electrophotographic process and apparatus of this invention, a drum-like photosensitive member and an endless toner-image bearing member are used. The bearing member is brought into close contact at a part thereof with the sensitive member. The sensitive member is electrically charged. After the bearing member is brought into close contact with the sensitive member, a latent image is formed on the sensitive member. The latent image is developed from an outer side of the bearing member so that a toner image is formed on its surface. To perform ordinary printing, the toner image is transferred onto a support member and then fixed. To conduct printing of multiple copies by using a master, the toner image on the bearing member is fused first to form a master, followed successively by electrical charging of the sensitive member, close contact of the master with the sensitive member, and whole-surface exposure from an outer side of the master. A latent image is formed on the sensitive member. Development of the latent image forms a toner image on the master, which is transferred onto a support member and then fixed.

摘要： An audio data reproducing device for reproducing digital voice signals from slanted tracks formed on a magnetic tape which is run at a speed different from a speed used for writing, comprising a unit for running the magnetic tape at a predetermined speed, and a playback rotary magnetic head adapted to be moved by a head moving unit in a direction of crossing the slanted tracks to effect follow-up tracing of the slanted tracks for reproducing signals recorded on the slanted tracks even if the magnetic tape is run at a speed different from the writing speed. The device includes a memory for storing audio data read out from the slanted tracks and a digital signal processor (DSP) for generating, in the low-speed playback mode, write address data for causing audio data recorded on a slanted track traced by the magnetic head to be captured in the memory only when the slanted track traced by the magnetic head is new. The digital signal processor also transmits readout address data conforming to playback speed to the memory to process audio data read out from the memory in accordance with the readout address with Lagrange interpolation. A clear sound conforming to the low-speed playback is produced on the real-time basis during the low-speed playback mode, while no sound is produced during still playback.
