Offering the highest-quality and most flexible encoding features of Adtec’s seasoned encoder line-up, the mediaHUB-HD 422
is a High- and Standard- Definition multi-CODEC workhorse. With the ability to encode any combination of HD or SD, MPEG 2
or MPEG 4 AVC with 4:2:0 or 4:2:2 color space, the mediaHUB-HD 422 supports past, present and future requirements. With
support for 40 encoding profiles and auto-detection capability for resolution and frame rate, this product can hit the ground
running regardless of your application.
Contribution, Distribution or Studio Encoding
Its rugged design and standard LCD front panel for status and configuration makes the mediaHUB-HD 422 ideal for mobile
contribution applications while the on-board web-based control application offers ease of use for distribution and studio
encoding. This all-in-one rack mountable unit is designed with standards compliance in mind and can easily be integrated with
other leading broadcast gear.

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.
Distribution Applications:
Distribute the highest quality MPEG 2 and MPEG 4 AVC Digital Television sound and pictures 24 x 7 x 365 with the
mediaHUB-HD 422. The mediaHUB-HD 422 supports ATSC, DVB, MPEG, and IPTV platforms delivering a pristine MPEG
2/MPEG 4 transport stream including broadcast quality Video, Audio with excellent lip sync, Closed Captions, Teletext, and
static ATSC and DVB service information. Add the DTA-3050 as for multiplexing and fully dynamic ATSC and DVB service
information applications.
Studio Applications:
Frame accurately capture video and four pairs of stereo audio with the mediaHUB-HD 422. The standard Sony 9-PIN interface
operates in Controller and Recorder mode allowing it to control a tape device or be controlled by a non-linear editor (NLE).
Encode in real-time with the Recorder mode directly from an NLE time line directly to file. Create High- and Standard-Definition
Cable Labs-compliant MPEG 2/MPEG4 transport streams with the mediaHUB-HD 422; ideal for VOD and DPI content
creation.

Front Panel
The mediaHUB-HD 422 should be installed into a one-rack unit 19” rack slot. Power should be applied to the unit and
configured with a valid IP address via the front panel. Once the IP is configured, you can use Telnet or a web browser to
configure and control the unit.

Front Panel Navigation
The mediaHUB-HD 422 has an LCD display on the front panel. Using the Mode, Select, Enter, Escape buttons and
directional buttons, you can navigate the front panel menu and control the unit.
The mediaHub-HD 422 is always logged in on startup•
If the device has logged out due to accident or a login duration timer being set (see below), you will need to log back
•
in.
To log in from a logged-out status:
StepAction
1Press <Select>
2Press <Up> arrow
3 Press <Select>
4 Press <Enter>
5 Press <Right arrow>
6 Press <Enter>
The front panel also has a login duration capability. This setting allows you to specify a time frame in which the unit will
automatically log itself out if it receives no control inputs via the front panel or API session.
To set the duration:
StepAction
1Press mode until you see the System Menu.
2Press <Select>
3Press the <Down> arrow
4Press <Select>
5Using the <Up> and <Down> arrows, select the value you wish.
6Press <Enter> to save your selection
Possible Values:
0 (Zero): The unit will not auto-log-out 1-9: The number of minutes until log out if no input is received.
The front panel also reports a snapshot of the current source. If you press the ESCAPE key until you reach the upmost menu
item, you will see something similar to this:
1920X1080 59i 33.77M
1DD 192K 2DD 192K 48
This snapshot tells you the current encode variables as shown in this diagram:.

There are 9 menu trees accessible from the front panel. Using the MODE button, you can scan through the System, Decoder,
Encoder, Transport, PID, Table, Profile, and Encryption menus. By pressing the SELECT button you can enter one of these
sub menus.

API Commands
There are five commands in the Profile group in the API command set for the mediaHub HD 422. They are:
Command HandlerCommandFunction
*.ECMD PROFILELISTlists all stored profiles
*.ECMD PROFILE[slot #] or [name] LOAD loads stored profile from the designated memory slot
*.ECMD PROFILE[slot #] SAVEsaves a profile to the designated memory slot
*.ECMD PROFILE[slot #] DELETEdeletes the profile stored at the designated memory slot
*.ECMD PROFILE[slot #] RENAMErenames the profile stored at the designated memory slot
Naming
When saving a profile to Slots 1-10 from the front panel, the system will default to the Service Name associated with that
configuration. To input a name of the user's choice, use the Profile/Save or Profile/Rename commands in a telnet/API
session.
