    • An audio apparatus having a detachable control panel or operating-part main unit includes a microcomputer for detecting an OFF state of an ACC position of the ignition key, or the attached/detached state of the operating-part main unit. When such states are detected, normal operations of the microcomputer; namely, the operations to turn on an SWD V.sub.DD terminal and an A/D port and to set a KEY DATA terminal into a standby mode, are stopped intermittently in order to execute a low consumption process in which electric power is consumed only for holding information in memory in the microcomputer. When the microcomputer detects the OFF state of the ignition key or the OFF state of an installation detection switch and, an alarm ON state is set in the memory in the microcomputer, then an alarm sound is generated from a speaker for a predetermined time. When the alarm sound is unnecessary, the state of the memory in the microcomputer can be updated to an alarm OFF state by depressing a function button and operating the ignition key. When the installation detection section detects the removal of the operating-part main unit, on the basis of a decrease in voltage value of an installation detection switch section and CPU recognizing the removal of the operation-part main unit, a control section sends control signals to a power supply limiting circuit and a data transmission switch section.

    • First and second memories are provided for receiving key signals which control a display to output a video composition made up of a plurality of video signals. The key signals are received from a key signal generator in synchronism with the speed of the key signal generator. The first memory receives a key signal directly, while the second memory receives a gated key signal for storing a key signal related to, for example, a still image, and the gating is controlled so that the key signal in the second memory is only overwritten when it is expressly intended to do so. A read address generator controls the reading out of key signals from both memories, in synchronism with the speed of the display apparatus which displays the video images. A further gate may be provided to control input of key signals into the first memory, this further gate being controlled by the state of the output key signal coming from the second memory. Another aspect of the invention relates to a system comprising a plurality of first memories for receiving, storing, and outputting a plurality of key signals, respectively. A selector is provided for selecting one of the plurality of output key signals, and the selected key signal is received and stored in a second memory and outputted as a second output key signal. A priority order setting system selects and outputs the first output key signals from the first memory and the second output key signal from the second memory according to a first priority order. A second priority order setting system may select and output the first output key signals according to a second priority order.
    • 提供第一和第二存储器用于接收控制显示器以输出由多个视频信号组成的视频构图的键控信号。 与键信号发生器的速度同步地从键信号发生器接收关键信号。 第一存储器直接接收密钥信号,而第二存储器接收用于存储与例如静止图像相关的密钥信号的门控密钥信号,并且门控被控制,使得第二存储器中的密钥信号仅被覆盖 当它明确打算这样做。 读取地址生成器与显示视频图像的显示装置的速度同步地控制从两个存储器读出键信号。 可以提供另一个门来控制键信号到第一存储器的输入,该另外的门由来自第二存储器的输出键信号的状态控制。 本发明的另一方面涉及一种包括分别用于接收,存储和输出多个键信号的多个第一存储器的系统。 提供选择器用于选择多个输出键信号之一,并且所选择的键信号被接收并存储在第二存储器中并作为第二输出键信号输出。 优先顺序设置系统根据第一优先顺序从第二存储器中选择并输出来自第一存储器的第一输出键信号和第二输出键信号。 第二优先顺序设置系统可以根据第二优先顺序选择并输出第一输出键信号。
