The Real Time Streaming Protocol (RTSP) is a network control protocol designed for use in entertainment and communications systems to control streaming media servers. The protocol is used for establishing and controlling media sessions between endpoints. Clients of media servers issue commands such as play, record and pause, to facilitate real-time control of the media streaming from the server to a client or from a client to the server.
Digital storage media command and control (DSM-CC) is a toolkit for developing control channels associated with MPEG-1 and MPEG-2 streams. It is defined in part 6 of the MPEG-2 standard and uses a client/server model connected via an underlying network.
A VoIP phone or IP phone uses voice over IP technologies for placing and transmitting telephone calls over an IP network, such as the Internet, instead of the traditional public switched telephone network (PSTN).
A service delivery platform (SDP) is a set of components that provides a service(s) delivery architecture for a type of service delivered to consumer, whether it be a customer or other system. Although it is commonly used in the context of telecommunications, it can apply to any system that provides a service. Although the TM Forum (TMF) is working on defining specifications in this area, there is no standard definition of SDP in industry and different players define its components, breadth, and depth in slightly different ways.
Network Access Control (NAC) is an approach to computer security that attempts to unify endpoint security technology, user or system authentication and network security enforcement.
SIM Application Toolkit (STK) is a standard of the GSM system which enables the subscriber identity module to initiate actions which can be used for various value-added services. Similar standards exist for other network and card systems, with the USIM Application Toolkit (USAT) for USIMs used by newer-generation networks being an example. A more general name for this class of Java Card-based applications running on UICC cards is the Card Application Toolkit (CAT).
A home server is a computing server located in a private residence providing services to other devices inside or outside the household through a home network or the Internet. Such services may include file and printer serving, media center serving, home automation control, web serving, web caching, file sharing and synchronization, video surveillance and digital video recorder, calendar and contact sharing and synchronization, account authentication, and backup services.
Video Share is an IP Multimedia System (IMS) enabled service for mobile networks that allows users engaged in a circuit switch voice call to add a unidirectional video streaming session over the packet network during the voice call. Any of the parties on the voice call can initiate a video streaming session. There can be multiple video streaming sessions during a voice call, and each of these streaming sessions can be initiated by any of the parties on the voice call. The video source can either be the camera on the phone or a pre-recorded video clip.
PacketVideo Corporation or PV was a San Diego-based company that produced software for wireless multimedia, including the display of video on mobile handsets. The PacketVideo name wasn't actively used after being acquired by Lynx Technology.
In telecommunications, Long-Term Evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported.
Flat IP architecture provides a way to identify devices using symbolic names, unlike the hierarchical architecture such as that used in "normal" IP addresses. This form of system is of more interest to mobile broadband network operators.
Vision was a mobile browser developed by Novarra Inc. that ran on Java Platform, Micro Edition. It was first released in 2002, and the final release was in 2009.
TwonkyMedia server (TMS) is DLNA-compliant UPnP AV server software originally offered by TwonkyVision GmbH and sold by Lynx Technology. Development and support ceased October 2018 with the shutdown of Lynx Technology Germany GmbH. TMS runs on Linux, Mac OS X, Windows XP, Windows Vista, Windows Home Server, and Windows 7 computers as well as Android, iOS, and other mobile platforms. TwonkyMedia server can be used to share and stream media to most UPnP AV or DLNA-compliant clients, in addition to non-UPnP devices through the HTML, RSS, and JSON supported front ends. After the PacketVideo acquisition of Berlin-based TwonkyVision GmbH by 17 October 2006, Twonky was renamed PVConnect by November 2007, but the name was changed back to TwonkyMedia server by 7 January 2010. Corporate parent NTT DOCOMO sold PacketVideo NorthAmerica and Europe to Lynx Technology on 10 May 2015 and PacketVideo Japan exactly one year later on 10 May 2016 transferring the Twonky product line to Lynx, renaming TwonkyMedia Server to Twonky Server. Twonky Server was maintained all the time by the former TwonkyVision employees which worked for the German subsidiary Lynx Germany GmbH. Lynx Germany GmbH was shut down 10/2018.

The Helix Universal Media Server was a product developed by RealNetworks and originates from the first streaming media server originally developed by Progressive Networks in 1994. It supported a variety of streaming media delivery transports including MPEG-DASH RTMP (flash), RTSP (standard), HTTP Live Streaming (HLS), Microsoft Silverlight and HTTP Progressive Download enabling mobile phone OS and PC OS media client delivery.
Adaptive bitrate streaming is a technique used in streaming multimedia over computer networks. While in the past most video or audio streaming technologies utilized streaming protocols such as RTP with RTSP, today's adaptive streaming technologies are almost exclusively based on HTTP and designed to work efficiently over large distributed HTTP networks such as the Internet. It works by detecting a user's bandwidth and CPU capacity in real time and adjusting the quality of the media stream accordingly. It requires the use of an encoder which can encode a single source media at multiple bit rates. The player client switches between streaming the different encodings depending on available resources. "The result: very little buffering, fast start time and a good experience for both high-end and low-end connections."
Access network discovery and selection function (ANDSF) is an entity within an evolved packet core (EPC) of the system architecture evolution (SAE) for 3GPP compliant mobile networks. The purpose of the ANDSF is to assist user equipment (UE) to discover non-3GPP access networks – such as Wi-Fi or WIMAX – that can be used for data communications in addition to 3GPP access networks and to provide the UE with rules policing the connection to these networks.
Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high quality streaming of media content over the Internet delivered from conventional HTTP web servers. Similar to Apple's HTTP Live Streaming (HLS) solution, MPEG-DASH works by breaking the content into a sequence of small segments, which are served over HTTP. Each segment contains a short interval of playback time of content that is potentially many hours in duration, such as a movie or the live broadcast of a sports event. The content is made available at a variety of different bit rates, i.e., alternative segments encoded at different bit rates covering aligned short intervals of playback time. While the content is being played back by an MPEG-DASH client, the client uses a bit rate adaptation (ABR) algorithm to automatically select the segment with the highest bit rate possible that can be downloaded in time for playback without causing stalls or re-buffering events in the playback. The current MPEG-DASH reference client dash.js offers both buffer-based (BOLA) and hybrid (DYNAMIC) bit rate adaptation algorithms. Thus, an MPEG-DASH client can seamlessly adapt to changing network conditions and provide high quality playback with few stalls or re-buffering events.
