Thursday, November 25th, 2010AGP standards for Accelerated Graphics Port or Advanced Graphics Port. The high-speed interface has been in use for years, and was developed for motherboards to attach graphics cards and assist in 3D graphics acceleration. While the AGP port provided significant improvements when it was brought to the market (over PCI), it is currently being largely phased out for the PCI-Express (PCI-e) interface. Regardless, motherboards and graphics cards still are available that use the AGP standard.

Tuesday, November 23rd, 2010Automatic Frequency Control Read More »
Automatic Frequency Control (AFC) applies to tuning in radio and TV receivers to keep it on frequency. It is also sometimes refereed to as Automatic Fine Tuning (ATF). The AFC circuit in the receiver device aids in reducing the tuning error of a TV tuner that is almost on proper frequency for a desired channel. In modern sets with digital tuners this feature is usually available and can’t always be switched off. There are circumstances under which AFC is better switched off but in general use it is beneficial.

What is IEEE1394, FireWire, i.Link?
Monday, September 20th, 20101394 Card’s full name is the IEEE1394 Interface Card, Sony and other video equipment manufacturers call it iLink, however, the creator of this interface technology – Apple call it Firewire. IEEE1394 is an external serial standard, 400Mbit / s speed. When it come in to use, it was was expected to be a substitute for other external scsi bus, but after a few years, it was only used to connect digital cameras. So I see some people say, to replace the 1394 bus will be USB2.0. But during the past year, with lower costs, 1394 card have rapidly growing popularity. Are beginning to have a number of other related equipment, such as digital cameras, hard drives, webcam, etc..

What is UDF and UDF/ISO？
Tuesday, September 14th, 2010What is UDF? And what is UDF/ISO?
UDF Read More »
One of the major achievements of DVD is that it has brought all the conceivable uses of CD for data, audio, video, or a mix of all three, within a single physical file structure called UDF, the Universal Disc Format. Promoted by the Optical Storage Technology Association (OSTA), the UDF file structure ensures that any file can be accessed by any drive, computer or consumer video. It also allows sensible interfacing with standard operating systems as it includes CD standard ISO 9660 compatibility. UDF overcomes the incompatibility problems from which CD suffered, when the standard had to be constantly rewritten each time a new application like multimedia, interactivity, or video emerged.
