Cisco IP/TV Broadcast Servers
Cisco IP/TV Broadcast Servers are equipped with IP/TV Server software. They
deliver on-demand or scheduled rebroadcasts of IP/TV programs that include
synchronized media produced with Web Presenter, ScreenCaster, and SlideCast.
IP/TV Broadcast Servers are configured with video capture cards to encode
streams from analog video and audio sources. T hey can receive content from
analog sources such as video cameras, video cassette recorders (VCRs), satellite
feeds, cable feeds, or existing Active Streaming Format (ASF), Audi o Video
Interleaved (AVI), or MPEG digital files. IP/TV Broadcast Servers can deliver live
events, such as a chief executive officer’s speech to thousands of employees, while
using the network bandwidth of an individual stream.
IP/TV Broadcast Servers offer varying compression techniques, depending upon
application requirements and available bandwidth. They are ideal for multicasting
live events or prerecorded programs on a scheduled basis.
This section describes the following Cisco IP/TV Broadcast Servers:
•Cisco IP/TV 3425 and 3425A Broadcast Servers
•Cisco IP/TV 3426 Broadcast Server
•Cisco IP/TV 3427 Broadcast Servers

Cisco IP/TV 3425 and 3425A Broadcast Servers

Cisco IP/TV 3425 and 3425A Broadcast Servers support high-pe rformance
encoding, with all encoding done in hardware. They are configured with Optibase
MovieMaker video capture cards. The Cisco IP/TV 3425 Broadcast Server
captures real-time and prerecorded content an d streams it over the network using
television-quality MPEG-1 or broadcast-quality MPEG-2 comp ression
techniques for the highest-quality streaming. The Cisco IP/TV 3425A Broadcast
Server is identical to the IP/TV 3425 Broadcast Server, but encodes and delivers
only television-quality MPEG-1 streams.
Cisco IP/TV 3425 and 3425A Broadcast Servers are configured for AC-input
power and have a single power supply installed. They have two 10/100BASE-T
Ethernet/Fast Ethernet ports with RJ-45 receptacles. Port Ethernet 0 supports
