Up to 6875 single carriers 1 kHz apart are QAM modulated with up to 64 states.
“Coded” means that the data to be modulated has error control.
Orthogonality means that the spectra of the individual carriers do not influence each other as a spectral maximum always coincides with a spectrum zero of the adjacent carriers. A single-frequency network is used for the actual transmission.

Bi-phase is an older synchronisation technology used in the film industry. Typically, the clock was derived from a box that hung off of large film mag recorders. This box emitted a pulse that provided sync.
Working with pulses alone, bi-phase sync did not provide location information, making it a rather limited solution.

A modified form of OFDM. A modulation scheme used for digital transmission that is employed by the European DVB system. It uses a very large number of carriers (hundreds or thousands), each carrying data at a very low rate. The system is relatively insensitive to doppler frequency shifts, and can use multipath signals constructively. It is, therefore, particularly suited for mobile reception and for single-frequency networks.

A) Contraction of binary digit. A single digit in a binary number. b) A binary representation of 1 or 0. One of the quantized levels of a pixel. c) An instruction in a data transmission, usually part of a word (byte) with high status = 1, and low status = 0.
Industry:Entertainment
The total amount of bits available on the media being used.
In DVD, the bit budget of a single sided/single layer DVD5 disc is actually 4.7 GB.
Industry:Entertainment
Used to implement the physical combination of the coding and decoding circuits.
Industry:Entertainment
The number of levels that a pixel might have, such as 256 with an 8-bit depth or 1024 with a 10-bit depth.
Industry:Entertainment
Representing each level of a video or audio signal as a number, usually in binary form.
Industry:Entertainment
The incorrect interpretation of a binary bit by a message processing unit.
