| Depending on the compression methods used, the video clip can be played back from | the Windows AVI structure or through the capture card. |
| Sources for video capture normally include | VCRs and camcorders. |
| A video decoder circuit is used to convert the analog signal into a stream of | digital signals |
| The characteristics of the decoded TV signal are as YUV, where Y refers to | the luminance of the signal color, and the UV portion describes the color component of the signal. |
| The video compression chip reduces the size of the file by removing | redundant information from consecutive frames. |
| Video-compression schemes can reduce the size of a video file by | a ratio of up to 200:1. |
| When the digitized video is recalled for output purposes, the | file is reapplied to the compression chip, which restores the redundant information to the frames. |
| During video decompression the analog signals are | converted back into the proper VGA format and are applied to the video-out connector at the back plate of the card. |
