Introduction

Cisco MXE 3500 is an appliance that provides comprehensive transcoding services and integrates into the network to deliver the following media processing capabilities:

Video content to be shared across the network to virtually any type of endpoint

Innovative post production features that transform ordinary video content into studio quality output

Collaboration with other applications delivered by Cisco's suite of media products

Ingest of MPEG-2 Transport Streams (MPEG-2 video payload and AC3 or Layer II audio payload) and output of stream transcoded to WMV, Flash 8, or H.264 formats

Extraction of an audio track from a video and performing speech-to-text transcription and graphic overlays (subtitles)

The Cisco MXE 3500 Resource Manager augments the capabilities of the Cisco MXE 3500 by intelligently load balancing job processing across multiple Cisco MXE 3500 devices and by delivering fault tolerance to deployment.

Browser Requirements

You must use one of following web browsers to access the Folder Attendant User Interface (UI) or Web UI:

Firefox 3 or later. Firefox 3.5 is recommended.

Internet Explorer 8 is supported.


Note When accessing Cisco MXE 3500 UIs, set your display resolution to 1280 x 1024 pixels for best results, or you may encounter issues with scrolling and display (CSCsu29805).


For information about the Cisco MXE 3500 components, see the User and Admin Guide for Cisco Media Experience Engine 3500.

Installation and Upgrade Requirements

The Cisco MXE 3500 is an appliance on which the Cisco MXE 3500 Release 3.0 software comes installed. This section includes the following topics:

Supported Deployment Models

Licensed Features

Important Notes

Supported Deployment Models

You can deploy Cisco MXE 3500 in the following two configurations:

Standalone Deployment—This deployment consists of one or more Cisco MXE 3500 devices running as individual devices, each with its own license, user interfaces, job profiles, and so on. This deployment supports one predefined administrative user. The following software product ID (PID) supports this deployment: MXE-3500-v3LIC-K9. See also the "Licensed Features" section.

Resource Manager Deployment—This deployment consists of one or more Cisco MXE 3500 devices running as a single group with one set of user accounts, job profiles, licensed features, and user interfaces; additionally, this deployment includes the User Administration feature.

There are two types of Cisco MXE 3500 devices in a Resource Manager deployment: a single Cisco MXE 3500 Resource Manager and up to nine Cisco MXE 3500 Resource Nodes. The Resource Manager not only functions as a multidevice manager that load balances transcoding jobs across the Resource Nodes, but also functions as a Resource Node that performs transcoding jobs. The following software PIDs support this deployment:

MXE-3500-31LIC-K9 (CISCO MXE 3500 Version 3.1 SW) (All Nodes)

MXE-3500-RMLIC (CISCO MXE 3500 Resource Manager License)

MXE-3500-RNLIC (CISCO MXE 3500 Resource Node License)

A Resource Manager license is required for the first Cisco MXE 3500 in a cluster.

A Resource Node license is required for each of the remaining Cisco MXE 3500s in a cluster.

All members of a cluster must have the same option licenses.

See also the "Licensed Features" section.

Licensed Features

This release supports the following additionally licensed features:

MXE-3500-STLIC (Cisco MXE 3500 Speech To Text License)

MXE-3500-GRLIC (Cisco MXE 3500 Graphics License)

MXE-3500-LVLIC (Cisco MXE 3500 Live Transcoding License)

MXE-3500-GLBLIC (Cisco MXE 3500 License Bundle (Includes: Graphics, Live))


Note Cisco MXE 3500 ships with a few general speaker profiles that are trained for common regional accents in the United States. You can obtain a speaker-independent profile on Cisco.com in the Video, Cable and Content Delivery > Media Experience Engines > Cisco MXE 3000 Series > Cisco MXE 3500 software download area.


For details about obtaining a license file to enable the software for your deployment, see the Deployment and Administration Guide for Cisco Media Experience Engine 3500. This guide also provides information about installing a license, configuring the Cisco MXE 3500, upgrading from a standalone to a Resource Manager deployment, and troubleshooting deployments. You can access the guide at the following URL:

http://www.cisco.com/en/US/products/ps9892/prod_maintenance_guides_list.html


Note Before you request a software license on Cisco.com for your deployment, see the Deployment and Administration Guide for Cisco Media Experience Engine 3500 for licensing requirements.


Important Notes

Power Cords and Power Supplies

There is one power cord shipped with the Cisco MXE 3500, and one power supply. If the customer orders the redundant power supply, there are two power cords and two plugs in the chassis.

Standalone and Resource Manager Deployments

The proper configuration of Samba server generally ensures that directory locations are accessible from all Hosts for both standalone and RM machines.

File Formats

A maximum of 8 audio tracks is supported with QuickTime format.

Re-wrapping is supported only for MPEG Encoder with an MPEG-PS input file (CSCsu08447).

Job Profiles

Cisco MXE 3500 ships with preconfigured Job Profiles. A Job Profile is a template that defines how jobs are processed, and it contains the settings that are required to process jobs from beginning to end. Job Profiles are optimized for different types of input media, encoding output, and distribution, and they align with modern distribution devices, such as iPod, iTunes, and so on. See the "Standard Cisco MXE 3500 Job Profiles" section in the User and Admin Guide for Cisco Media Experience Engine 3500 to learn more about the preconfigured Job Profiles.


Caution We strongly recommend that you use the preconfigured Job Profiles and change settings only if you understand the consequences. Modifying preconfigured Job Profile settings or creating new Job Profiles with settings that media standards do not support can result in job processing failures or produce undesirable output.

User Interface

The Live Capture feature using Capture Card hardware is not supported; related settings are nonfunctional (CSCsr96178).

Tape jobs are not supported.

Forensic Watermarking and Fingerprint features are not supported; therefore, related settings are nonfunctional.

Configuration of Quicktime encoder setting is done through a direct access to the device, not through the Web UI. See the User and Admin Guide for Cisco Media Experience Engine 3500 for more information.

The User Administration and Profile Spaces features are not available with Cisco MXE 3500 standalone deployment. The User Administration feature is available only with a Resource Manager deployment. See also the "Supported Deployment Models" section.

IP Capture

The maximum supported resolution of input stream is 1080i, and only MPEG-2 encoding is supported for input payload. The maximum resolution of output stream is 720p.

We recommend that you configure an IP Capture job to use the Immediate mode. Otherwise, as the IP Capture job progresses, an intermediate file that continuously grows is created, filling up the disk storage and affecting the operation of the device.

Take care when archiving the output of an IP Capture job on the local disk storage of the device or on an external storage device. As the IP Capture job progresses, an archive file that continuously grows is created, filling up the disk storage and affecting the operation of the device or external storage device.

Speech to Text

You can obtain an additional speaker-independent speech profile Cisco.com in the Video, Cable and Content Delivery > Cisco MXE 3500 software download area.

We recommended that the audio input is via a direct microphone /lapel microphone connection (LINE IN) to the camcorder/recording device. It is imperative that the video recording is carried out with quiet surroundings (low ambient noise). See Guidelines for Improving the Accuracy of Speech to Text in the Deployment and Administration Guide for Cisco Media Experience Engine 3500 on Cisco.com for more information.
