dvdSanta: The Most Easy to Use DVD Creating Tool
dvdSanta is an All-in-One software that lets you copy, create, convert and burn your DVD movies. It can copy 9GB double layer DVD movies into a 4.7GB DVD-R disc, can turn your photos into DVD movies with Hollywood style motion effects, can convert other video formats (avi, wmv, vob, asf, DivX, Mpeg,...) into DVD video, can transfer miniDV camcorder tapes directly to DVD video. >>> |
- Birefringence
DVD glossary
Optical distortion caused by different indices of refraction for separate directions of polarization, often caused by stress in the optical medium. Produced during CD or DVD injection molding by shrinkage, flow lines, and inclusions in the substrate. Usually more severe near the outer diameter.
- Bit
One binary information element having the value ZERO or ONE.
- Bit Error Rate (BER)
Probability that a read bit does not match the written bit.
- Block
Group of contiguous recorded characters treated as a unit and containing one or more logical records. A logical block contains 512x28 bytes, where n is an integer (0, 1, 2, ...) Normally used to characterize a DVD ECC block or a CD subcode block, or section, but can also refer to a CD frame.
- Block Error Rate (BLER)
Number of blocks, each containing one or more erroneous bits, per unit of time (usually seconds).
- Blue Book
Proprietary Philips/Sony specification (blue cover) for Enhanced Music CD.
- Bump
Exposed area on the master viewed from the entrance surface. Also used to designate indentations caused by foreign matter during molding.
- Burst
Contiguous error groups usually caused by a large tangential physical defect. ISO burst limit for CD is less than seven successive frames, each containing two or more successive error bytes.
- Burst Cutting Area (BCA)
Optional annular area on a DVD disc near lead-in containing low reflectance radial stripes of encoded content provider information.
- Byte
Contiguous set of eight data bits, represented by an equal or greater number of channel or recorded bits.
B-frame
Bi-directional frame. The frame in an MPEG sequence created by comparing the
difference between the current frame and the frames before and after it.
Bandwidth
(1) The amount of data that can be transferred or processed per unit of time.
(2) The range of frequencies a device operates within. The wider the bandwidth,
the better the performance. Bandwidth is measured in kHz.
Bass
Frequencies in the lower part of the audio spectrum (20 Hz - 160 Hz).
Bi-directional Prediction
A form of compression in which the codec uses information not only from frames
that have already been decompressed, but also from frames yet to come. The codec
looks in two directions: ahead as well as back. This helps avoid large spikes in
data rate caused by scene changes or fast movement, improving image quality.
Bit
A binary digit that indicates 0 for "off" and 1 for "on."
Bitmap
An array of pixels.
Bits
per Pixel
The number of bits used to represent the color information of a pixel. 1 bit per
pixels allows using only 2 colors (usually black and white), 24 bits are used
for True Color images (more than 16,7 million colors).
Bit
Rate
An indication of the amount of data processed for some time period. Usually
measured in bits per second (bps). Also called Data Rate. The higher the rate
the better the picture/sound.
Bitstream
A stream of data meant to be processed sequentially. Dolby Digital sound on a
DVD is encoded onto a bitstream for processing.
Bonded
Disc
In order to make a DVD more resilient, and less likely to warp, two 0.6mm layers
are permanently bonded together. This also allows DVDs to be two-sided.
Book A
DVD Read only specification.
Book B
DVD Video specification. Organized into Physical, Logical, and Application
sections.
Book C
DVD Audio specification.
Book D
DVD Write once specification.
Book E
DVD Rewritable specification.
Brightness
The value of a pixel along the black-white axis.
Pocket DVD Wizard
The Pocket DVD Wizard allows you to make backup copies of your personal DVD's, Mpeg, AVI and DivX video and then play them on your Windows Mobile™ Pocket PC. Imagine the possibilities! You can now record your favorite TV program with your DVD recorder and transfer it to your Pocket PC, then watch it later in the office, or on the beach! >>> |
| There are 4 standard formats. D10 and D18 are not
as common. A DVD-5 (single sided) DVD-Video disc will hold nominally 133 minutes of high quality MPEG-2 encoded video, together with three surround-sound audio channels and four subtitle channels. (Without video compression one DVD-5 disc would hold only about 3 minutes of video). A DVD-9 (dual layer) disc increases the playing time to 240 minutes of continuous video. A DVD-10 (double sided) disc will hold a nominal 133 minutes on each side (ie 266 minutes in all), but the disc needs to be turned over to play the other side. A DVD-18 (dual layer, doubled sided) disc can hold 240 minutes on each side and the disc also needs to be turned over to play the other side. Most DVD is D9 or D5 format. DVD-Cloner can clone D9 to just ONE DVDr/rw disc (D5 format) without evident losing. |
