AbstractThis report provides discussions and conclusions about delivering video programming over either asynchronous transfer mode (ATM) or Internet protocol (IP) backbones and infrastructures. Why does anyone care about this topic? The main reason is that dozens of billion-dollar-per-year companies have been racing each other to install and implement major fiber optic and satellite backbones to deliver voice, data, and video services. There is probably more bandwidth than can be quickly absorbed by the markets. As a result, all these players want to know if their backbones can be used for the most bandwidth-hogging applications, which are all connected in some way to delivering video. Billions of future dollars are at stake, and one of the key questions being asked is: Which backbone infrastructure is better for video? ATM or IP? The report explains the three items that are most important to a video delivery system, which are:
- Bandwidth
- Quality of Service Minimum Requirements
- Ability To Tolerate Latency And Jitter
The report presents a brief introduction to the MPEG-2 Transport Protocol, and then looks at how well ATM or IP serve the needs of ten applications.
The ten types of video service to be considered are:
- High Definition TV Production
- Digital TV Production
- Digital TV Contribution
- Digital Satellite Distribution
- Digital Cable Distribution
- Digital Broadcast Distribution
- VDSL Distribution
- ADSL Distribution
- Dial Up Phone Line
- Wireless Phone
The report also briefly profiles a dozen companies that provide local phone services to more than 200 million local subscribers. These companies also provide wireless voice (cell phone and PCS) services to another 81.6 million subscribers. They've got about 126 million long distance customers, about 375 thousand digital subscriber loop customers, and more than 6.2 million total Internet subscribers.
Most major telecommunications companies also have investments, partnerships, or outright owned subsidiaries that operate in countries other than the one in which their corporate headquarters is located.
