    • PURPOSE:To reduce the flickering on a large screen TV, by installing a memory which stores the signal of one horizontal scanning and a delay circuit of one-field scanning time, and scanning the outputs from the delay circuit at a double speed. CONSTITUTION:When signals having one-field information and represented by A, B,..., respectively, are successively inputted into an AD converter 15, the signals are converted into digital signals and the signals A, C, and E are supplied to a delay circuit 17 and memory 19 and the other signals B, D, and F are supplied to another pair of delay circuit 18 and memory 20 by means of a switch 16. Since the delay circuits 17 and 18 have a delay time of one-field scanning time only, the same content is read out for two times within one horizontal scanning time, and TV signals converted into analog signals at DA converters 21 and 22 are alternately outputted via a switch 23 which performs the change- over operation at 1/2 horizontal scanning time.
    • 目的:为了减少大屏幕电视上的闪烁,安装存储一个水平扫描信号的存储器和一场扫描时间的延迟电路,并以双倍速度扫描延迟电路的输出。 构成:当分别具有由A,B,...表示的一场信息的信号被连续输入到AD转换器15中时,信号被转换为数字信号,信号A,C和E被提供给 延迟电路17和存储器19以及其他信号B,D和F通过开关16提供给另一对延迟电路18和存储器20.由于延迟电路17和18的延迟时间为一倍, 在一个水平扫描时间内相同的内容被读出两次,并且在DA转换器21和22处转换成模拟信号的TV信号通过开关23交替输出,开关23以1 / 2个水平扫描时间。

    • PURPOSE:To restart service automatically and smoothly, by detecting an abnormal state such as a power failure occurring to a terminal device and reporting that to a broadcasting center, and allowing a center controller to receive the report and reporting a state before the power failure, etc., to the terminal device. CONSTITUTION:A terminal 500 detects a CPU incorporated in a terminal controller 510 executing an initial routine which is stored in a nonvolatile memory incorporated in the terminal device 510 in case of a power failure and executed only when the CPU of the terminal controller 510 is powerd on. If the destruction of the contents of the nonvolatile memory or malfunction due to a noise occurs, that is detected from a change of a redundant bit provided for detecting the generation of a data pattern which is never detected in normal operation or abnormality, reporting the abnormality to the center controller 110. The center controller 110 receives this report to rereport a channel number, charged channel section, etc., to the terminal controller 510 by a charged channel report command and also reports accounting information which is reported from the terminal 500 and stored. Consequently, the contents of the memory of the terminal controller 510 are restored to the state before the abnormality occurrence completely and the service is restarted automatically and smoothly.
    • 目的:通过检测终端设备发生的电源故障等异常状况并向广播中心报告,并允许中央控制器接收报告并报告电源故障前的状态,自动,平稳地重启业务, 等等,到终端设备。 构成:终端500在停电的情况下,检测结合在终端控制器510中的执行初始程序的CPU,该初始程序存储在结合在终端装置510中的非易失性存储器中,并且仅当终端控制器510的CPU被强制执行时才执行 上。 如果发生非易失性存储器的内容的破坏或由于噪声而发生的故障,这是从为检测在正常操作或异常中从未检测到的数据模式的生成而提供的冗余位的改变来检测的,报告异常 中央控制器110通过收费信道报告命令接收该报告以将信道号,收费信道部分等重新发送给终端控制器510,并且还报告从终端500报告的会计信息,以及 存储。 因此,终端控制器510的存储器的内容恢复到完全异常发生之前的状态,并且服务自动且平稳地重启。

    • PURPOSE: To relieve the load of a center and to reduce the line traffic, by confirming instantly the present operating mode at a terminal side when a request takes place at the terminal for processing its countermeasure.
      CONSTITUTION: The information at each toll channel is informed to the center cpu 110 to all terminal devices 500 in advance together with a toll channel notice command and stored in a memory of a terminal controller 510. Taking the operating mode because of the time zone limit of the broadcast service as "1"∼"3", when the operating mode "1" is given when the cpu is operated at first, this operating mode information is stored in a memory of a terminal controller 510. When a viewer depresses a toll channel key on a key pad 520, a terminal control section checks the present operating mode, discriminates that the broadcast service of a toll program is not done and outputs rejection telop information on a receiver 530.

    • 目的:为了缓解中心的负载并减少线路流量,当终端发出请求时,通过立即确认终端侧的当前操作模式来处理其对策。 规定:每个收费信道上的信息被预先通知给所有终端设备500的所有终端设备500以及收费通道通知命令并存储在终端控制器510的存储器中。由于时区限制而采取操作模式 作为“1” - “3”,当首先操作cpu时给出操作模式“1”时,该操作模式信息被存储在终端控制器510的存储器中 当观众按压键盘520上的长途通道键时,终端控制部分检查当前的操作模式,判断收费节目的广播服务没有完成,并且在接收机530上输出拒绝字幕信息。
