    • A VTR is responsive to designation of an index scan mode for detecting an index signal recorded on a control track of a tape with the tape being traveled at high speed. During high-speed traveling, a video signal received by a contained tuner is outputted and applied to a monitor receiver. Every time the index signal is detected, the starting portion of each recorded program is reproduced in a normal reproducing mode during a short time period and time-base compressed, to be combined with the above described received video signal. The combined video signal for picture-in-picture display is applied to the monitor receiver externally provided, so that a received video signal is displayed on a main screen while a reproduced video signal is displayed on a subscreen. When a short time period elapsed, PIP control is cancelled, so that a high-speed traveling mode is established until the next index signal is detected. When a user turns an operation mode setting switch on, the contents recorded on the tape can be monitored in various desired modes so long as the operation mode setting switch is turned on, irrespective of the mode.
    • VTR响应于索引扫描模式的指定,该索引扫描模式用于检测记录在磁带上的索引信号,磁带以高速行进。 在高速行驶期间,输出由包含的调谐器接收的视频信号并将其应用于监视接收机。 每次检测到索引信号时,在短时间段和时基压缩期间,以正常再现模式再现每个记录节目的开始部分,以与上述接收到的视频信号组合。 用于画中画显示的组合视频信号被应用于外部提供的监视器接收器,使得接收到的视频信号被显示在主屏幕上,同时再现的视频信号被显示在子画面上。 当经过短时间段时,PIP控制被取消,使得在检测到下一个索引信号之前建立高速行驶模式。 当用户打开操作模式设置开关时,只要操作模式设置开关打开,就可以以各种所需的模式监视记录在磁带上的内容,而不管模式如何。

    • A transport stream (TS) is recorded and the recorded TS is reproduced simultaneously. An input PID parser extracts the first packet only to be recorded, the second packet to be recorded and to be used for controlling, and the third packet to be used only for controlling from among the TS packet that constitutes the TS supplied from a descrambler. The first and second packets are supplied to a receiver and supplied to a hard disk drive (HDD) for recording. The second and third packets are supplied to an MUX. On the other hand, the TS packet stored in the HDD is read out and supplied to the MUX by way of an output PID parser. The MUX multiplexes the second or third packet supplied from the input PID parser and the TS packet read out from the HDD, and supplies the multiplexed packet to a CPU that controls a descrambler or the like.
    • 记录传输流(TS),同时记录记录的TS。 输入PID解析器仅提取要被记录的第一数据包,要被记录并用于控制的第二数据包,以及仅用于从构成从解扰器提供的TS的TS数据包中进行控制的第三数据包。 第一和第二分组被提供给接收机并提供给用于记录的硬盘驱动器(HDD)。 第二和第三分组被提供给MUX。 另一方面,存储在HDD中的TS分组被读出并通过输出PID解析器提供给MUX。 MUX复用从输入PID分析器提供的第二或第三分组和从HDD读出的TS分组,并将多路复用分组提供给控制解扰器等的CPU。
