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. They can receive content from
analog sources such as video cameras, video cassette recorders (VCRs), satellite
feeds, cable feeds, or existing Active Streaming Format (ASF), Audio 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-performance
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 and streams it over the network using
television-quality MPEG-1 or broadcast-quality MPEG-2 compression
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
autodetect speed mode and full-duplex operation.
