Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The feedback algorithms used by the encoder to avoid overflow of the video-rate buffer. The video-rate buffer is a FIFO which holds the coded video prior to output into the channel.

a) A complete set of quantized levels containing all of the bits.
Bytes consisting of 8 to 10 bits per sample are typical.
b) Group of eight bits. Can be used to represent a character. Microcomputer instructions require one, two, or three bytes. A word can be one or more bytes.
c) A group of adjacent binary digits operated upon as a unit, capable of holding one character in the local character set, and usually shorter than a computer word (frequently connotes a group of eight bits). Current usage within the context of electronic production concerns is tending to define a byte as eight bits to have a consistent data unit for measuring memory capacities, etc.
d) 8 bits. The combination of 8 bits into 1 byte allows each byte to represent 256 possible values. See Megabyte, Gigabyte, Terabyte.
1 byte = 8 bits = 256 discrete values (brightness, color, etc.) 1 kilobyte = 1,024 bytes (not 1000 bytes) 1 megabyte = 1,048,576 bytes (not one million bytes) 1 gigabyte = 1, 073,741,824 bytes (not one billion bytes) 1 terabyte = 1,099,511,627,776 bytes (not one trillion bytes)

Coatings that are specially treated to reduce the coating resistance, and thus prevent the accumulation of static electrical charge. Untreated, non-conductive coatings may become highly charged, causing transport, noise, and dust-attraction problems.

An error in a computer program. Eliminating errors is known as debugging.

Analog compression is used at one point in the communications path to reduce the amplitude range of the signals, followed by an expander to produce a complementary increase in the amplitude range.

A bit in a coded bit stream is byte-aligned if its position is a multiple of 8-bits from the first bit in the stream.

A test to make sure a particular device (such as the keyboard, mouse, or a drive) is set up and working properly.

Refers to adjustment tones which are available within the recorder for adjusting record level and bias.

a) The process of electronically processing a digital video picture to make it use less storage or to allow more video to be sent down a transmission channel. b) The process of removing picture data to decrease the size of a video image. c) The reduction in the volume of data from any given process so that more data can be stored in a smaller space. There are a variety of compression schemes that can be applied to data of which MPEG-1 and MPEG-2 are called lossy since the data produced by compression is not totally recoverable. There are other compression schemes that are totally recoverable, but the degree of compression is much more limited.
