In 2004, Intel released Intel High Definition Audio (HD Audio) which is a successor that is not backward compatible with AC'97. [2] HD Audio has the capability to define up to 15 output channels, but in practice most motherboards provide no more than 8 channels (7.1 surround sound).
It defines a new license-free, royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system. The video signal is not compatible with DVI or HDMI , but a DisplayPort connector can pass these signals through.
A normal dynamic loudspeaker does this naturally, but the tiny metal diaphragm of the moving-iron speaker will let much switching noise pass, as will many direct couplings (though there are exceptions to this, e.g. filtered "speaker in" ports on some motherboards and sound cards). This use of the PC speaker for complex audio output became less ...
Three RCA connectors - yellow for composite video, and white and red for stereo audio RCA connector: Widely used in consumer electronics for audio and video. A single connector must be used for each signal. SCART: Consumer electronics, mostly in Europe. Carries analog stereo sound, along with composite video and/or RGB video.
On older personal computer motherboards, the southbridge is one of the two chips in the core logic chipset, handling many of a computer's input/output functions. The other component of the chipset is the northbridge, which generally handles high speed onboard communications.
S/PDIF and TOSLINK connectors on a piece of audio equipment. S/PDIF (Sony/Philips Digital Interface) [1] [2] is a type of digital audio interface used in consumer audio equipment to output audio over relatively short distances. The signal is transmitted over either a coaxial cable using RCA or BNC connectors, or a fibre-optic cable using ...
A 15-pin VGA connector for a personal computer A 21-pin SCART or JP21 connector for a television. The various RGB (red, green, blue) analog component video standards (e.g., RGBS, RGBHV, RGsB) use no compression and impose no real limit on color depth or resolution, but require large bandwidth to carry the signal and contain a lot of redundant data since each channel typically includes much of ...
Close-up of a sound card PCB, showing electrolytic capacitors, SMT capacitors and resistors, and a YAC512 two-channel 16-bit DAC. [1] The integrated circuit on the left is a 3403 single power supply quad operational amplifier. Sound cards use a digital-to-analog converter (DAC), which converts recorded or generated digital signal data into an ...
