Althos Publishing announces IP TV Dictionary, The Leading IP Television Resource. IP Television Dictionary provides definitions and illustrations covering the latest video over data and Internet television technologies and provides the understanding needed to provide IP video services.
Many changes continue to occur in video and data networks and this book is the perfect solution for those involved or interested in the operation of television networks and service providers. This reference book explains the latest television technologies, assists with the explanation of technologies by using many diagrams and pictures. It is a great reference tool that allows people to effectively communicate with other people involved in the IP Television industry.
The convergence of technologies and systems means more competitors and new industry terms. As a result, communicating with others has become an alphabet soup of acronyms and technical terms. IP TV Dictionary solves this challenge by providing definitions of the latest technical terms and acronyms along with self-explanatory diagrams.
This reference includes:
· Over 10,000 of the latest IP TV, IP Video, and broadband datacom definitions
· Contains 4,000+ of the latest industry terms and acronyms
· Has 400+ diagrams and photos to help explain complex definitions
· Includes directories of magazines, associations and ITVSPs
To ensure this dictionary contains the latest definitions, 12 experts were used from different sectors of the IP Television industry to add and edit definitions. Many of the definitions were created using our technical books that have been edited by hundreds of industry reviewers. Diagrams and pictures in the dictionary assist the understanding of technical terms by providing functional and operational views.
IP TV Video System
This figure shows how a basic IP television system can be used to allow a viewer to have access to many different media sources. This diagram shows how a standard television is connected to a set top box (STB) that converts IP video into standard television signals. The STB is the gateway to a IP video switching system. This example shows that the switched video service (SVS) system allows the user to connect to various types of television media sources including broadcast network channels, subscription services, and movies on demand. When the user desires to access these media sources, the control commands (usually entered by the user by a television remote control) are sent to the SVS and the SVS determines which media source the user desires to connect to. This diagram shows that the user only needs one video channel to the SVS to have access to virtually an unlimited number of video sources.
TV Program Distribution
This figure shows how an IP television system can distribute information through a switched telephone network. This example shows that end users who are watching a movie that is initially supplied by media center that is located some distance and several switches away from end users (movie watchers). When the first movie watcher requests the movie, it is requested from the telephone end office. The telephone end office determines that the movie is not available in its video storage system and the end office switch requests the movie from the interconnection switch. The interconnection switch also determines the movie is not available in its video storage system and the movie is requested from the distant media source. When the movie is transferred from the media center to the end customer, the interconnecting switches may make a copy for future distribution to other users. This program distribution process reduces the interconnection requirements between the switching distribution systems.
Serving Prep for IP TV
This figure shows how the number of simultaneous IP television users per household geographic serving area can vary based on the data transmission capability of the service provider. This example shows that each single IP television user typically requires 3 to 4 Mbps of data transfer. For a telephone system operator that uses distance sensitive DSL service, this example shows that the service provided will be limited to providing service to a single IP television when the data transfer rates are limited to 3-4 Mbps. When the data transfer rate is above 5-7 Mbps, up to 2 IP televisions can be simultaneously used and when the data transmission is between 10 to 14 Mbps, up to 3 IP televisions can be simultaneously used.
