Several standards exist or have been proposed for digitized video transmission. All result in a serial digital data stream. Table 1 lists the key standards. |
|
Networks can be configured in a number of topologies. These include a bus, with or without a backbone, a star network, a ring network, which can be redundant and/or self-healing, or some combination of these. Each topology has its strengths and weaknesses, and some network types work better for one application while another application would use a different network type. |
|
As video over fiber transmission systems evolve into multi-service communications networks, with stringent up-time requirements, system redundancy becomes a must to provide remote monitoring of the system. |
|
These types describe, primarily, the quality of the signal. Broadcast studio quality requires a much higher signal fidelity, while consumer quality baseband requires is less demanding. |

It describes the digital technologies that provide consumers with integrated access to voice, high-speed data services, video-on-demand (VOD), and interactive delivery services. |
