In the past broadcast and cable TV services predominated. Now there is a growing audience for TV services provided over broadband connections.
This e-learning course provides an introduction to the technical infrastructure necessary to provide video services over Internet Protocol (IP) networks.
You will get the most out of this course if you already have an understanding of the operation of IP networks and the advanced techniques used to improve the performance of such networks. It is recommended that the PTT e-learning courses TAF: ""IP networks"" and TAH: ""Advanced IP networks"" are studied before attempting this course.
This e-learning course has a comprehensive range of interactive training facilities to provide a total learning experience. Technical words and acronyms have links to an online glossary giving an instant explanation. Interactive simulations explain concepts and systems operation.
Onscreen question sessions at the end of each module test understanding and provide further guidance and instruction. Revision links provide quick access to subjects previously discussed and relevant to the module being studied. Once studied as a structured, assessed course, the content can be browsed for revision or reference.
By the end of this course you will be able to:
- describe the composition, benefits and use of MPEG programme and transport streams and their transmission over an IP network.
- describe the role of programme association and programme map tables, and the Event Information Table (EIT).
- describe the principles and features of, and compare, the various types of video service: narrowcasting, video on demand (VoD) and near VoD services.
- compare the role and features of broadcasting, multicasting and unicasting.
- describe the roles of the various software and hardware components of an IPTV system including those at the head end, the exchange and the customers' premises.
- describe the role of, and compare, transport protocols, the operation of IGMP multicasting, and the use of RTSP in providing a video on demand service.
- describe the role and operation of admission control and resource reservation for Video on Demand and multicasting services.
- describe the use of Digital Storage Media - Command and Control (DSM-CC) in providing interactive television and information services.
- describe the testing of a Video over IP service with reference to the causes and effects of impairments in an IP network, the factors that affect channel changing speed and the types, capabilities and use of IPTV test equipment.
- describe methods of integrating an IPTV service with a next generation network with reference to NGN-integrated IPTV and IMS-based IPTV.
