- Q: The principle of cable digital TV set top box
- 4, the upper application software: the implementation of service providers to provide a variety of services, such as: electronic program guide, quasi video on demand, video on demand, data broadcasting, IP phones and video phones. Upper layer applications are independent of STB hardware, which can be used on a variety of STB hardware platforms to eliminate application software dependence on hardware. (7) display technology: TV and computer display, CRT display is a mature technology, but with a low resolution display text, especially less than 24 * 24 words, the problem becomes more complicated. The television picture tube is low resolution of big pitch pipe, only suitable for image display 720 x 576 or 640 x 480, its deflection system is fixed, is 525 60Hz or 625 50Hz design, and digital TV has more than 18 kinds of display format. The Internet is in line with the VESA format. Obviously, the TV's display system can't adapt to so many formats. In addition, the TV adopts a low frame rate interlaced scanning method. When displaying graphics and text, the brightness signal has the background flicker, and the horizontal line has the flicker between the lines. If the computer graphic conversion scan to the TV set, will only appear in the horizontal edge odd field or even field, display time close to human visual persistence, will produce the edge flicker phenomenon is severe, so to use Internet TV, the TV show to remedy the defects. According to the technical difficulty and cost, currently with two kinds of methods were improved, an anti flicker filter, the image is in proportion to the sum of three adjacent line up in a row, which only appears in the image reproduction in every single game, called the three line filtering method. The three line filtering method is simple and easy to implement. But it reduces the sharpness of the image and is suitable for interlaced tv.
