Cisco Media Processor can be controlled by a Web interface (both remotely and
locally), by SNMP, and by Front Panel Controls located on the system itself. How to
use each of these to configure and manage the encoder is discussed. As the settings
for these methods are basically the same, the detailed descriptions for the settings are
contained in one chapter, the Web interface chapter.

In addition to encoding video and up to three stereo audio streams, Cisco Media
Processor can optionally process Line 21 Captioning information and convert this to
both CEA-608 and up-converted CEA-708 captioned data. For VC-1 Advanced Profile,
this captioning data is contained within the video bitstream. For any profile, the
captioning data may also be saved in a SAMI (.smi) file. For applications where digital
608, 708 or SAMI captions can not be utilized, Cisco Media Processor also supports
Open Captions which renders caption data directly onto the source video thus allowing
for viewing of closed captions on any decoder.
The compressed data streams can be encapsulated in ASF or in a MPEG-2 Single
Program Transport Stream, either of which may be saved to disk. The MPEG-2
Transport Stream may also be output over IP-Multicast. The ASF Stream can be pulled
from the encoder and pushed to a Windows Media Server.
