Graphics subsystem bypass method and apparatus

本发明提供一种用于将屏上显示(OSD)的图形图像覆盖到模拟或数字视频源信号上的屏上显示子系统。该OSD系统有一视频图形旁路路径(22)和图形旁路开关(24)，用于在不需要该OSD子系统将图形插入源信号的时间间隔里引导一模拟视频信道绕过该OSD子系统。 The present invention provides an on-screen graphics (OSD) subsystem for overlaying OSD graphic images onto analog or digital video source signals. The OSD system has a video...

Zusammenfassung:	本发明提供一种用于将屏上显示(OSD)的图形图像覆盖到模拟或数字视频源信号上的屏上显示子系统。该OSD系统有一视频图形旁路路径(22)和图形旁路开关(24)，用于在不需要该OSD子系统将图形插入源信号的时间间隔里引导一模拟视频信道绕过该OSD子系统。 The present invention provides an on-screen graphics (OSD) subsystem for overlaying OSD graphic images onto analog or digital video source signals. The OSD system has a video graphics bypass path (22) and graphics bypass switch (24) for directing an analog video channel around the OSD subsystem during time intervals when the OSD subsystem is not required to insert graphics into the source signal.
