V-Chip

V-Chip is a feature that allows you to program your TV so that children can’t see certain programs or channels. You can block programs based on violence, sexual content or other content you do not want your children to watch.

V-chip software reads a code that most broadcasters send with programs. The code contains an age-based rating and content rating (not all programming is rated). You can choose to block those programs with ratings you don’t want your children to see.

Vertical Resolution

Vertical resolution refers to the number of horizontal lines that a video display can paint to create one frame or image. Higher resolutions (more lines) produce better quality pictures. Television resolution is often stated in vertical resolution.

The NTSC (analog) television standard used in the United States has a vertical resolution of 525 lines. Of these, 43 lines are used to carry other information, such as closed captioning text and on-screen guide information, so the true maximum vertical resolution for NTSC is about 480 lines.

Vertical resolution for high definition television is set at either 1080 interlaced lines (1080i) or 720 progressive scan (non-interlaced) lines (720p).
