The system supports high bandwidth demands from applications like IPTV, Internet video, HD programming, and mobile video by increasing the speeds over existing fiber. Typically, increasing the speeds from 10G to 40G to 100G entails trade-offs such as shortening the distance of each network segment or increasing optical dispersion because of the ...
The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IPv4 networks to establish multicast group memberships. IGMP is an integral part of IP multicast and allows the network to direct multicast transmissions only to hosts that have requested them.
Miracast is "effectively a wireless HDMI cable, copying everything from one screen to another using the H.264 codec and its own digital rights management (DRM) layer emulating the HDMI system". The Wi-Fi Alliance suggested that Miracast could also be used by a set-top box wanting to stream content to a TV or tablet.
The widespread adoption of Wi-Fi in new classes of smaller devices made the need for ad hoc networking much more important. Even without a central Wi-Fi hub or router, it would be useful for a laptop computer to be able to wirelessly connect to a local printer. Although the ad hoc mode was created to address this sort of need, the lack of ...
The Transport layer in the OSI model, as well as TCP/IP model, provides statistical multiplexing of several application layer data flows to/from the same computer. Code-division multiplexing (CDM) is a technique in which each channel transmits its bits as a coded channel-specific sequence of pulses. This coded transmission is typically ...
Precept developed an Internet video product named IP/TV. IP/TV was an Mbone compatible Windows and Unix-based application that transmitted single and multi-source audio and video traffic, ranging from low to DVD quality, using both unicast and IP multicast Real-time Transport Protocol (RTP) and Real time control protocol (RTCP).
An optical network terminal (ONT, an ITU-T term), also known as an optical network unit (ONU, an IEEE term), is used to terminate the optical fiber line, demultiplex the signal into its component parts (voice telephone, television, and Internet access), and provide power to customer telephones.
Competitive service providers are now offering access services over a variety of access technologies, including wireless optical (i.e., Terabeam) and metro-Ethernet networks. Old telco protocols and transport methods (T1 lines and time-division multiplexing ) are replaced with access methods that are appropriate for the underlying transport.
