Triple Play
What is Triple Play Technology?
In telecommunications, Triple Play service is a technology term for the provisioning of three services-high-speed Internet, television ( video on demand or regulat broadcasts) and telephone-over a single broadband connection. Triple Play focusses on a combined business model rather than on solving technical issues or creating a common standard.In addition to the video, voice, and data, other services in Triple Play include high-speed interactive browsing and voice calls. For this to happen, each subscriber requires a minimum bandwidth of 18 Mbps to support these services. Today, Triple Play Services are offered by cable television operators as well as by telecom operators.
How Triple Play is carried through?
For telephone local exchange carriers, Triple Play is delivered to its residential base using a combination of optical fibre and digital subscriber line (DSL) technologies (called fibre in te loop).This configuration uses fibre communications to reach distant locations, and uses DSL over an existing plain old telephone service (POTS) twisted pair cable as last mile access to the subscriber's home.
Cable television operators use a similar architecture called hybrid fibre coaxial to provide subscriber homes with broadband, but use the available coaxial cable rather than a twisted pair for the mile transmission standard. Subscriber homes can be in a residential environment, multi-dwielling units, or even in business offices.
Using DSL over twisted pair, television content is delivered using IPTV ( Internet Protocol TV ) where the content is streamed to the subscriber in an MPEG-2 transport format. Ona n HFC network, television may be a mixture of analog and digital television signals.
A set-top-box is used at the subscriber's home to allow the subscriber to control viewing and order new video services such as movies on demand. Internet is delivered via ATM or DOCSIS, typically provided as a 10 Base-T Ethernet port to the subscriber. Voice can be delivered using a traditional (POTS ) interface as part of the legacy telephone network, or can be delivered using Voice over IP (VoIP). In an HFC network, voice is delivered using VoIP |
