    摘要： The invention relates to a circuit arrangement for controlling the supply voltage (Ubvar) of a video signal deflection unit, especially a horizontal deflection unit (1) pertaining to a television apparatus or a monitor. The inventive arrangement comprises a control device (7) that receives a measured frequency signal (A) corresponding to the current frequency value of an input frequency (HSYNC) and a measured voltage signal (B) corresponding to the current voltage value of the supply voltage (Ubvar). The control device can adjust the operating frequency (D) of the video signal deflection unit (1) and the supply voltage (Ubvar) in an interdependent manner, according to said two measured signals (A, B) and in such a way that malfunctioning of the video signal deflection unit (1) is reliably prevented, whereby said operating frequency depends on the input frequency (HSYNC).

    摘要： A method and an apparatus for remotely interacting with a PC (107). A local PC interface unit (101) is coupled to a PC (107). The interface unit receives audio/visual output signals from the PC (107). Unit (101) converts the audio/visual signals to a format for ordinary TV. Local input devices are also coupled to the PC interface unit (101). The local PC device wirelessly transmits the converted audio/visual output signals to TV interface unit (103) which is coupled to a TV and stereo for playback. A remote input device interface unit (105) located near the TV receives multiple signals from multiple input devices. The interface (105) multiplexes the remote input device signals into a data stream wirelessly transmitted to the PC interface unit.

    摘要翻译： 一种用于与PC远程交互的方法和装置。 在一个实施例中，本地PC接口单元耦合到位于本地站点的PC。 本地PC接口单元被耦合以从PC接收视频输出信号和音频输出信号。 诸如键盘和鼠标的本地输入设备以及诸如PC的监视器和扬声器的外围设备也耦合到本地PC接口单元。 本地PC接口单元将由PC产生的视频和音频信号转换成适合在普通家庭电视上播放的格式。 本地PC设备然后经由RF无线链路将经转换的音频/视频信号发送到TV接口单元，TV接口单元耦合到TV以在远程站点重放。 TV接口单元还产生适合于从普通家庭立体声收听的独立音频信号。 诸如键盘，鼠标，轨迹球，操纵杆或游戏控制器的远程输入设备被耦合到远程输入设备接口单元，该远程输入设备接口单元可以位于与电视和家庭立体声相同的房间中。 远程输入设备接口单元从每个远程输入设备接收远程输入信号，并将远程输入信号复用到单个远程输入数据流中。 远程输入数据流通过无线链路传输回本地PC接口单元，以实现与远程位置的PC的交互。

    摘要： A method for generating display correction waveforms for a CRT display comprises the steps of selecting one of a plurality of trace portions for forming part of a correction waveform, the trace portions having different average values. Completing each of the correction waveform by combining each selected trace portion with a respective retrace portion such that all completed correction waveforms have a predetermined average value. The correction waveforms may have vertical and/or horizontal rates.

    摘要： Connected to the power supply Vcc is a first capacitor C1, which is connected via a first change-over switch SW1 to the reference potential point or a second capacitor C2. The second capacitor C2 is charged by the voltage control circuit 45 under control by the pump-up voltage control signal so that the capacitors C1 and C2 are charged respectively during the scanning period. Upon input of the NTSC signal, the change-over switch SW1 is connected to the reference potential point and the charging voltage of the first capacitor C1 is used as the pump-up voltage; Upon input of a signal having a short vertical flyback period such as the signal from personal computers, the total of the charging voltages at the first and second capacitors C1 and C2 is used as the pump-up voltage.
