A method for offloading decoding of encoded video data from a computer system executing a video player application playing the encoded video data to a remote display terminal still enables the video player application to overlay transparent or semi-transparent graphical elements, such elements, such as user interface controls, onto the video, despite not having access to decoded video data. A video decoding function call from the video player application is intercepted and replacement video data is provided to the video player application rather than a decoded version of the encoded video data. The video player application is thereby able to overlay graphical elements onto the replacement video data to create composite video from which the graphical elements are then able to be subsequently extracted and transmitted with the encoded video data to remote display terminal, which decodes the video data and overlays the graphical elements for display. |

In a switching control circuit, a length of a soft start period is set by a time constant of an external circuit that is connected to a soft start terminal of a switching control IC. After a voltage of the soft start terminal has reached a predetermined voltage at the termination of the soft start period, the on-pulse period of a first switching device is limited by a maximum value. When a Zener diode is connected between the soft start terminal and ground, the upper limit voltage of the soft start terminal is a Zener voltage and, hence, the maximum on-pulse period is limited by this voltage. As a result, the switching control circuit and a switching power supply apparatus, which have a soft start function and a power limiting function, are reduced in size and cost by limiting the number of terminals. |
