Delivering IPTV(2 Days or 12hours)
As Service Providers seek to diversify their service offering through initiatives such as triple play, IPTV is experiencing a significant surge in popularity around the globe. This course is designed to provide an end to end view of an IPTV network, defining the key incentives for migration to or adoption of IPTV. The course will focus on the fundamental protocols associated with both Multicast and VoD delivery, in addition to discussing key topics such as network architecture, media coding, QoS / QoE provision and security.
Who Should Attend
Network Engineers requiring a concise understanding of the protocols and techniques used in IPTV provision. Content Providers requiring an appreciation of the distribution of IPTV media.
