Transition Minimized differential signaling. RED,
TMDS
GREEN BLUE AND CLOCK
Display Data Channel. A two way communication
DDC between source and sink for negotiating format and
resolution. It transmit EDID info
Extended Display Identification Data. Information
EDID about displays supported features and capabilities,
such as device ID. aspect ratio, serial number.. etc
Hot plug Detect. Recognize connection between
HPD
source and sink
Consumer Electronics Control. An HDMI feature that
CEC
allows user to control device settings
Mathematically lossless Allows original data to be perfectly reconstructed
Compression from its compressed state
Visually Lossless Decoded image is not reconstructed mathematically
Compression and appears the same as original
data compression techniques in which some amount
Lossy Compression of data is lost. This technique attempts to eliminate
redundant information.
Time it takes for a bit to travel from its sender to its
Latency
receiver. Its due to scaling, encoder processing...etc
, Society of Motion Picture and Television Engineers.
1/2 major media standard such as TV production,
SMPTE picture filming, digital cinema. They have established
over 800 standards and other recommended
practices. TraTde-mark the color bar test
Digital Cinema Initiatives. Comprised of major motion
DCI picture studio to establish specifications for digital
cinema systems to ensure quality, reliability.
National Television System Committee standard used
NTSC in North America and most of South America, 30 fps.
ANALOG TV Broadcasting standard
Phase Alternating Line standard mostly used
PAL overseas, 25 frames are transmitted each second.
ANALOG TV Broadcasting standard
Sequential Color avec Memory standard for French
SECAM and Asian broadcast television. ANALOG TV
Broadcasting standard
Advanced Television Systems Committee. DIGITAL TV
ATSC standard. Used in North America, Mexico and
Canada. Establishing standard for HDTV.
Digital Video Broadcasting. The terrestrial
broadcasting standard adopted by the United
DVB
Kingdom and other European countries.DIGITAL TV
standard
Integrated Services Digital Broadcasting. Japanese
ISDB
standard for transporting DIGITAL TV.
Digital Terrestrial Multimedia Broadcast. DIGITAL TV
DTMB
standard for China, Cuba and HK
High-Bandwidth Digital Content Protection. A
mechanism developed by Intel to only allow media to
HDCP
be played with HDCP approved devices, preventing
unauthorized copying of protected content.
, Technical term referring to the reproduction of sound
Audio
as an electrical signal coming from electronic device.
Engineer POV for technical and physical aspect of
Critical Listening
sound, frequency, range and pitch
listening is a neutral and unbiased evaluation that
takes facts and measurements into consideration
Object vs subjective without influence from personal bias. Subjective
listening listening is an evaluation that does induce the
listener's personal bias, but may not lend to verified
facts and measurements.
20-20,000 hz; cycle per second. High pitch= high
Frequency for human ear
frequency, vice versa for low frequency
Standard voltage for 1mV to 100mV
microphone
2 Conductor wires. One carries analog audio signal
(Hot) and the other is ground wire (earth or shield)
Unbalanced Signals They are susceptible to electrical interference.
Terminated with various connector and jacks (RCA, 1/8
Mini jack or TRS, 1/4 Mono or TS)
3 wires. One hot wire with audio signal, one cold wire
carriying signal in opposite or reverse polarity. This
help cancel noise and interference. The third is
Balanced Signal
ground shield. Signal that does not degrade over long
distances (XLR, TRS and Captive screws like Pheonix,
erioblock and terminal block)
Carry one channel of balanced or unbalanced audio.
It can be reproduced through several speakers but all
Mono signals
speaker are still reproducing the same signal. Like
earbuds!
