3GP is defined in the ETSI 3GPP technical specification. [1] 3GP is a required file format for video and associated speech/audio media types and timed text in ETSI 3GPP technical specifications for IP Multimedia Subsystem (IMS), Multimedia Messaging Service (MMS), Multimedia Broadcast/Multicast Service (MBMS) and Transparent end-to-end Packet-switched Streaming Service ().
OpenBSC was a project to develop a free software implementation of GSM protocol stack and elements. It runs on Linux and requires an E1 interface (ISDN Primary Rate Interface , via mISDN ). It is written in C and licensed using the GPL (≥v2) license.
The Download Delivery Method is intended for “download and play” services. A File Repair service may be offered to compensate for unreliable delivery. MBMS has been standardized in various groups of 3GPP (Third Generation Partnership Project), and the first phase standards are found in UMTS release 6. As Release 6 was functionally frozen by ...
3GPP timed text tools (SUB/SRT/TTXT/TeXML), VobSub import/export, BIFS codec and scene conversion between MP4, BT and XMT-A, LASeR codec and scene conversion between MP4, SAF, SVG and XSR (XML LASeR), XML scene statistics for BIFS scene (BT, XMT-A and MP4), Conversion to and from BT, XMT-A, WRL, X3D and X3DV with support for gzip.
This is a listing of open-source codecs—that is, open-source software implementations of audio or video coding formats, audio codecs and video codecs respectively. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats.
GSM/UMTS were the most widespread 2G/3G wireless standards worldwide. Most countries used only the GSM family. A few countries, including China, the United States, Canada, Ukraine, Trinidad and Tobago, India, South Korea and Japan, used both standards. 3GPP2 had its last activity in 2013, [2] and the group has been dormant ever since.

The Adaptive Multi-Rate (AMR, AMR-NB or GSM-AMR) audio codec is an audio compression format optimized for speech coding. AMR is a multi-rate narrowband speech codec that encodes narrowband (200–3400 Hz) signals at variable bit rates ranging from 4.75 to 12.2 kbit/s with toll quality [ 3 ] speech starting at 7.4 kbit/s.
