3G is an ITU specification for the third generation (analog cellular was the first generation, digital PCS the second) of mobile communications technology. 3G promises increased bandwidth, up to 384 Kbps when a device is stationary or moving at pedestrian speed, 128 Kbps in a car, and 2 Mbps in fixed applications. 3G will work over wireless air interfaces such as GSM, TDMA, and CDMA. The new EDGE air interface has been developed specifically to meet the bandwidth needs of 3G.
A container format that is a simplified version of the MPEG-4 (MP4) format that uses less storage and bandwidth for better streaming on mobile phones.
Short for the 3rd Generation Partnership Project, 3GPP is a collaboration agreement that was established in December 1998. The collaboration agreement brings together a number of telecommunications standards bodies. The original scope of 3GPP was to produce globally applicable Technical Specifications and Technical Reports for a 3rd Generation Mobile System based on evolved GSM core […]
- 3G USB Dongle
A 3G or WiMAX USB dongle is a portable device that attaches to a USB port to enable a PC to connect to WiMAX and (or) 3G networks. These connectivity dongles are popular with mobile users who require broadband Internet connectivity while on-the-go. Add-in cards for WiMAX or 3G are also available for laptops.
- 3:2 pulldown
3:2 pulldown, also called 3-2 pulldown, is a method of converting 24 frame per second (fps) motion picture video to 60 fps video, such as NTSC. In 3:2 pulldown, one frame of the film is scanned three times, the next frame is scanned twice, the next frame is scanned three times, and so on. Progressive […]
- 3-D audio
A technique for giving more depth to traditional stereo sound. Typically, 3-D sound, or 3-D audio, is produced by placing a device in a room with stereo speakers. The device dynamically analyzes the sound coming from the speakers and sends feedback to the sound system so that it can readjust the sound to give the […]
