当今电视机设计正朝着数字化技术方向发展。电视机数字化不仅提高了图象质量,而且增加了模拟电视机中不能实现的许多新的功能。继西德日本之后,英国不久也研制成功第一台带有遥控和文字广播的数字化电视机机芯ZX5000。西德ITT是目前唯一批量生产数字化电视机用集成电路芯片的公司。因此ITT电路便成为ZX5000机芯的重要组成部分。机芯中除了亮度和色度信号处理,同步和时基波形产生等采用ITT公司的集成电路之外,
Today’s television design is moving in the direction of digital technology. Television digitization not only improves image quality but also adds many new features not found in analog televisions. Following the West Germany, Britain soon developed the first digital television movement ZX5000 with remote control and text broadcasting. West Germany ITT is currently the only mass-produced digital television integrated circuit chip company. So the ITT circuit has become an important part of the ZX5000 movement. In addition to the movement of the luminance and chrominance signal processing, synchronization and time-base waveform generation using ITT’s integrated circuits,
