Pennsylvania Cable Network (PCN), a non-profit statewide cable television network with 10 million viewers, uses direct fiber connections to distribute live programming from its main HQ site in Camp Hill to the Comcast and Verizon cable systems and previously used satellite links to distribute to an additional 30 headends across the state.
According to Dean Vaccher, PCN Engineer, a key driver for replacing the satellite-based transmission with distribution over IP was the addition of high definition (HD) channels to PCN’s channel lineup. Previously, it only distributed standard definition (SD) NTSC 525 channels over C-band satellite links, with a yearly cost consuming a large chunk of its network operations budget. By replacing its satellite-based transmission with distribution over IP, PCN would be able to add HD channel distribution at a significantly lower cost than satellite.

NRWision, a community TV station serving the state of Nordrhein-Westfalen, used a filebased system for the first nine years of operations, to upload non-live content created in the studio over an internet connection to a playout server in Unitymedia's network operation center (NOC). While NRWision had been part of Unitymedia's channel line-up for quite some time, it was not able to broadcast live over the internet.
This may sound strange given the fact that NRWision has 1 Gb/s connections to the desktop and - as a university - has a high-speed direct access connection to the Internet backbone. However, NRWision realized that high-speed internet connection is not enough to ensure successful live broadcast.

This course consists of 7 modules, providing a thorough grounding in the principles and standards of Video over IP (Internet Protocol). Starting with the basics of using IP as a replacement for SDI, it goes on to look at RTP (Realtime Transport Protocol) streaming and the fundamentals of IP multicast, and then covers SMPTE ST 2022, SMPTE ST 2110, AES 67, AMWA NMOS, and PTP (IEEE 1588) – the key components of an IP based studio, OB truck or broadcast centre. The standards are dealt with in a way that is both clear and understandable, while at the same time giving the detail needed to be useful in real practical situations.
The course will appeal to anyone with basic knowledge of IP and SDI who wants to gain a good understanding of how IP is transforming the infrastructure of broadcasting and content production.
