VCD about 1374 kbps
DVD about 4500 kbps
DV about 25 Mbps (megabits per second).

Framerate - Stands for "Frames per second". It determines the performance of games, with a higher rate producing smoother graphics. A low rate will appear laggy/chuggy/slow/choppy and can make a game unplayable as ingame actions take far too long to complete with far too few frames. I would mark 30 frames per second as a minimum for satisfactory gameplay, and 40+ as smooth

HDTV - High Definition TV is high-resolution digital television combined with Dolby Digital surround sound (AC-3). HDTV is the highest DTV resolution in the new set of standards. This combination creates a stunning image with stunning sound. HDTV requires new production and transmission equipment at the HDTV stations, as well as new television equipment for reception by the consumer. The higher resolution picture is the main selling point for HDTV. Imagine 720 or 1080 lines of resolution compared to the 525 lines people are used to in the United States (or the 625 lines in Europe) -- it's a huge difference!
Of the 18 DTV formats, six are HDTV formats, five of which are based on progressive scanning and one on interlaced scanning. Of the remaining formats, eight are SDTV (four wide-screen formats with 16:9 aspect ratios, and four conventional formats with 4:3 aspect ratios), and the remaining four are video graphics array (VGA) formats. Stations are free to choose which formats to broadcast.
The formats used in HDTV are:
720p - 1280x720 pixels progressive
1080i - 1920x1080 pixels interlaced
1080p - 1920x1080 pixels progressive -

In addition, the use of S-Video (instead of composite video) to connect a S-VHS deck to a TV results in the native luminance / chrominance separation in both S-VHS and standard VHS being preserved, which also improves the image on your TV.

Videotape is also used extensively for professional digital video applications from news gathering to archival storage, although to some extent it's been replaced by hard drive and optical disc (DVD) storage. This is even more true in the consumer market where miniDV camcorders have largely been replaced by models which write to a hard Topdrive or directly to a miniDVD.
