Operations and Applications
Typical Operations
Contribution Applications: The Adtec mediaHUB-HD 422 supports a comprehensive array of video encoding profiles with
BISS encryption. A highly-robust, single-channel per carrier (SCPC) DVB compliant MPEG 2 or MPEG 4 Transport Stream is output via ASI and GIGE concurrently. For multiplexing many services or channels per carrier (MCPC), Adtec's DTA-3050 is the perfect companion product. The DTA provides 10 ASI inputs for flexibility and high performance throughput with exceptionally low jitter. It remaps PIDs, adds and drops services, enables DVB-CSA encryption, builds DVB Tables, and adds the ability to operate encoders and DTA's fully redundant.

Introduction to the Control Application
A web-based command and control (C&C) software application comes pre-installed on the mediaHub HD 422. Online updates will be available when future versions of this software is released along with product firmware.
Firefox: 3.0 (recommended)• MS Internet Explorer: 7.0 and higher• Safari: 3.0 and higher• Opera: 9.0 and higher•
Note for Safari users:
The C&C program is designed to use the Bonjour Zero Configuration Protocol.
•
When using Safari ©, click on the " ^^ " symbol to open a networked devices list.♦ Select the device to point the browser to that device's IPA.♦
Access
Access the C&C application by pointing your web browser to the unit's IP address. The following screen (image reduced for clarity) will appear:
Links to the unit's Release Notes and a link to Adtec's Technical Support contact page are also located on this screen.
Login

www.adtecdigital.com
The C&C Screen has two operating windows, the Status Bar and the Main Window:
Status Window: the Status Window is fixed- it will display regardless of what function is being displayed in the Main Window. The current parameters of the unit's encode, decode, and transport functions are always in view and are updated in real time. Further detail about the Status Window is covered in a later section of this manual. The Status Window also features "Jump Buttons" that serve as a second way to access associated Menu Tabs.
Main Window: the Main Window is used to access the device's controls and operating settings. The Main Menu Tabs determine which function is being controlled in the Main Window. Each Main Menu Tab is covered in more detail in further sections of this manual.
Important Note for mediaControl Users
Adtec's mediaControl software interface is not supported on the mediaHub HD 422's firmware and will not interface with the unit at all.
www.adtecdigital.com
The Status Window
The Status Window is a fixed component of the Command and Control interface- it constantly displays a summary of the mediaHUB-HD 422's current activity level regardless of which tab is selected in the Main Window.

Encoding Frequently Asked Questions
Scenario Information
What is the max mux rate with audio?
What is Video Auto Fill (VAF)?
What is Constant Capture (CCA)?
My encoder encodes great for a while, then stops. What's wrong?
What happens when the hard drive fills up with Constant Capture files?
Does a second Dolby channel have to be present? Do I have to have audio on the 2nd channel or is the Dolby signature in the file sufficient?
100,000,000
Video Auto Fill is an Adtec feature to reduce the amount of null packets in the Transport stream by automatically setting the Video Bitrate. The bitrate is automatically configured by the mediaHUB-HD based upon the Transport Mux Rate and the Audio rates (Transport Mux Rate - Audio Rate - minimal fill = Video Rate). VAF is recommended to be turned on for the highest possible video quality. Please note that 15Mbps is the highest possible video rate for Standard Definition Mpeg2.
Constant Capture is an Adtec feature to record encoded content 24/7/365 to the hard drive. To use this feature turn CCA on ( *.ecmd cca on). The user may also have the device automatically segment constant capture into files by setting a Record Time ( *.ecmd RCT). When doing continuous 24/7 recording, RCT is the length of each successive file with a range from 60 - 7200 seconds (1 min. - 2 hr.). Set RCT to 1800 to create a new file every 30 minutes (*.ecmd RCT 1800). Each successive file will be named accordingly with the time/date stamp that it was segmented. Setting record time to zero (0) disables file segmentation. Encodes will be captured as a single large file.
RDU or Record Duration is a setting that aids in providing studio fashion encoding. Please verify the Record Duration is set to 0 for 24 hour encodes. (*.ecmd RDU 0 )
The unit deletes the oldest file in sequence, and continues to loop through, replacing the next oldest file as each new file is saved.
No, and the Dolby signature should be sufficient.
How do I determine what bit rates I need to use to encode my spots?
How do I set up a multicast stream?
Why can't I transfer large file to my unit?
What is the ideal audio input level for analog audio?
This depends on your system's parameters.
Set it up on the Transmit -> Multicast Menu from the front panel: MODE: SEND MSP: 2000 MSI: 226.0.0.1
Depending on your network structure, an ftp timeout can occur when transferring large files. To correct this, change the ftp data timeout of your unit to 350 seconds. This can be done via telnet using command ftpdatatimeout 350 Note: The eth0 and eth1 cannot be on the same subnet.
0 (zero) dB is recommended for analog audio.

Studio Encoding via Adtec API Commands
To capture a file with a specific duration, you will need set the following API(s):
Capture File Name: Enter an absolute file name.
•
Example: * CFN /media/hd0/media/TESTFILE.mpg♦
Trans Mux Rate: For the file to capture to drive, the TMR must be lower than 40Mbps
•
Example: * TMR 39000000♦
Record Time: Set this value to 0. This keeps constant capture from breaking up your file into smaller segments.
•
Example: * RCT 0♦
Record Duration: Set this value to the desired record duration time.
•
Example: * RDU 00:00:30:00 (30 secs.)♦
Constant Capture: Constant capture must be turned on to record.
•
Example: * CCA 1♦
Once all settings are complete, save your configuration by issuing a * CF SAVE command.
To constantly capture, you will need set the following API(s):
Capture File Name: Enter an absolute file name.
•
Example: * CFN /media/hd0/media/TESTFILE.mpg. ♦ Note that this file name will be appended with a date/time stamp as is segments the file.♦
Trans Mux Rate: For the file to capture to drive, the TMR must be lower than 40Mbps.
•
Example: * TMR 39000000♦
Record Time: Set this value between 1800(secs) and 7200 (secs).
•
This is how long the encoder will encode before segmenting to another file.♦
Record Duration: Set this value to 0.
•
Example: * RDU 00:00:00:00♦
Constant Capture: Constant capture must be turned on to record.
•
Example: * CCA 1♦
Once all settings are complete, save your configuration by issuing a * CF SAVE command.
Once settings have been saved, you can issue a record from the API (* REC) or the front panel. When your file has been captured, you can FTP to the unit to retrieve it or confidence decode it by issuing a playspot command; for example, (* PS TESTFILE.MPG).

EIA-608/708 Captions
The new line of Adtec encoders (mediaHub HD Pro, mediaHub HD 422, and edje 5100) supports EIA-608 Captions in standard definition mode and EIA-708 Captions in high definition mode. The 708 captions must be carried as SMPTE-334M payloads with a DID of 0x61 and an SDID of 0x01.
The 608 to 708 conversion is especially useful in ATSC Terrestrial Applications.
In standard definition mode, the encoder automatically looks for 608 captions on line 21 when captions (CLC) are set to ATSC. When encoding 708 captions, the user may enter the Vertical Ancilleray line that the data resides on. We have found that it is common for most networks to put their data on VANC Line 9, the Adtec configured default.
