Page 23

DE285 HD Caption Decoder/VANC Monitor

section. To expand the module, click the downwards arrow at the top right hand corner.

5.4. ANC Trigger

The ANC Trigger tab allows you to create triggers made up of two parts: the ANC data of interest, and the behavior you would like to observe. The data type is selected using the DID/SDID value, and the trigger can be set on behaviors such as Present, Absent, Change, Data Change and line number. Setting triggers is a useful way to monitor incoming ANC data to check the frequency of events such as missing data. Using the web interface, triggers can be chosen and then monitored in a live–update pop-up window that is tied to your browser session, making the ANC analysis tool ideal for watching until an event occurs. To

Page 24

DE285 HD Caption Decoder/VANC Monitor

record triggers that will be stored on the DE285 for detailed viewing or to view information about infrequently occurring errors, please see the next section on Logging.

To set a trigger, select a DID/SDID value from the dropdown menu on the left and then choose a speciﬁc event type from the adjacent drop down menu. One of the following events can be chosen: “Present,” which triggers when a particular packet is present in the video stream, “Absent,” which triggers when a packet is not present in the video stream, “Change,” which triggers when the packet presence changes from being present to not present or vice versa, and “DataChange,” which triggers when the packet presence remains the same, but the data within the packet has changed. The events are evaluated on a per–ﬁeld basis.

After creating an ANC trigger, click on the Start button to monitor the trigger activity. A pop–up window will appear with multiple columns. The text in the upper left corner of the pop–up window indicates whether the trigger is active or has completed.

If the trigger is set to go off when the packet is absent, then the pop–up window will display the Trigger Count column and the Frame Number that the packet was missing from. If the trigger event is set to go off when the packets are present, changed or the data has changed, the pop–up window will display the Trigger Count, the Frame Number that

Page 25

DE285 HD Caption Decoder/VANC Monitor

the event has taken place in and the Line number in which the event happened.

To view the packets delivered at the trigger time, click the ‘+’ button to the left of the trigger number. Regardless of the event type, the pop–up window will display up to twenty instances of the triggered event. To stop a trigger, click the ’x’ button at the upper right corner of the pop–up window. To continue viewing current information about the trigger, reset the trigger by repeating the instructions to create a trigger.

By clicking on the View/Edit Active Triggers button, the running triggers can be managed by viewing the triggers, removing speciﬁc triggers, or removing all triggers. This feature is useful in multi–user environments, as well as situations in which the DE285 has unexpectedly lost power. If the message “This trigger is already in use.” occurs when attempting to set a trigger that does not appear to be in use, this feature can be used to check whether that trigger is in fact in use. If the trigger

Page 26

DE285 HD Caption Decoder/VANC Monitor

is not being observed by any other user, it can be removed using the pop–up window that displays the active triggers in a list. To remove one trigger, click on the trigger in the Trigger List so that it is highlighted and then click Remove to remove the selected trigger. To remove all of the active triggers, click Remove All. To return to the main window without modifying the active triggers, click the ’x’ at the top of the pop–up window.

5.5. VANC Capture

The VANC Capture tab provides a convenient way to capture real–time VANC data, with or without ﬁltering, so that it can be downloaded and reviewed. To begin capturing all VANC data, click on the Start button. The elapsed time is displayed in the upper right hand corner. To end the VANC capture, click on the Stop button. If only certain VANC data is of interest, click on the checkbox to the left of ’Filter Capture by DID/SDID(s)’ to reveal the ﬁlter submenu.

Using the dropdown menu on the left side of the submenu, choose the desired DID/SDID and click the Add button to the right of the dropdown

Page 27

DE285 HD Caption Decoder/VANC Monitor

menu. The added value will appear in the ’DID/SDID to Capture’ area on the right part of the screen. Repeat this process until all VANC data of interest is added to the list. To remove a ﬁlter item, highlight the item by selecting the DID/SDID value in the list and then click on the Remove button below the list. To clear all ﬁlters, click the Remove All button in the lower right hand corner. After selecting ﬁlters, start and stop the VANC capture process as previously speciﬁed. To save and view the captured VANC data as a binary dump, click on the Download button.

5.6. Logging

The Logging tab provides a customizable solution for gathering VANC data for in-depth analysis and debugging. Logging is ideal for checking the behavior of triggers over a longer time period, monitoring error messages, and for any situation in which a saved copy or printout for later reference is desired. Logs are saved in non-volatile storage on the DE285 box.

The VANC Analysis tools can record two types of behavior, Log Triggers

and Alarms. Log Triggers are similar to the normal triggers discussed in the previous section, but are intended for longer term use, when the user is not constantly watching the screen and waiting for a change. The Log Triggers operate only within the Logging tab, just as the normal triggers operate only within the VANC Triggers tab. Alarms are used to record the time and frame location of an error message. The Alarms report the content of the packet and are arranged in three categories in the Logging Options pop-up window.

5.6.1. Log Viewer

The Logging tab displays stored information regarding triggers and alarms, allows the log to be printed or saved, and provides options for the information the log stores. The default log screen shows all alarms and triggers that appear in the Log Viewer. The events are sorted by the time at which they occurred and also contain information about the event type and when the event triggers, if applicable. To view more information about the Trigger or Alarm, click on the ‘+’ button to the left of the the Trigger or Alarm of interest.

The Log Viewer display can be altered by using the “Filter By:” drop down menu to limit or expand which trigger or alarm types are being displayed. The displayed log can be updated by clicking the Refresh button, which is found at the upper right corner of the Logging module. To remove the current log information and start a new log, click the Clear Log button below the Log Viewer.

The current log can be saved or printed out to retain the information. Click on the Save As... button to save a copy of the log as an HTML ﬁle to a speciﬁed location. It may take 10 to 15 seconds to create the downloadable log. To print a copy of the log, click on Print to launch a pop–up window with print options. The printable copy can be ﬁltered by what is present in the log, much like the drop–down ﬁlter menu used for viewing the log. There is also an option to select the range of log entries printed, or the option to print all. After selecting the desired print options, click OK to choose a printer and print the log, or Cancel

Page 29

DE285 HD Caption Decoder/VANC Monitor

to discard the print options and return to the main window of the log viewer.

5.6.2. Logging/OSD Alarm Settings

To begin monitoring and storing Log Triggers and Alarms, click on Logging Options which will bring up a window in which Triggers and

Alarms can be assigned or removed. The pop–up window may take a few seconds to load. Log Triggers can be assigned in the top half of the pop–up window. Alarms can be selected in the lower half of the pop–up window by checking the desired boxes.

To set a Log Trigger, select a DID/SDID value from the dropdown menu on the left and then choose a speciﬁc event type from the adjacent drop down menu. There is also a checkbox that can be enabled for triggering on a selected line. One of the following events can be chosen: “Present,” which triggers when a particular packet is present in the video stream, “Absent,” which triggers when a packet is not present in the video stream, “Change,” when the packet presence changes from be-

Page 30

DE285 HD Caption Decoder/VANC Monitor

ing present to not present or vice versa, and “DataChange,” which triggers when the packet presence remains the same, but the data within the packet has changed. The events are evaluated on a per–ﬁeld basis. After selecting a value for DID/SDID and Trigger On, click Add to begin logging occurrences of the Log Trigger.

To set any of the Alarms, click the box to the left of the desired Alarm. After selecting all Log Triggers and Alarms of interest, click Apply and then OK to begin logging the selected Log Triggers and Alarms and to return to the Log Viewer. To disregard the changes made, click Cancel to return to the Log Viewer.

The available alarms are grouped into three categories: General Alarms, Caption Pair Alarms and Error Alarms.

General Alarms

There are ﬁve alarms in the General Alarms category that can be used to get an overview of possible problems.

Alarm Name Description Unknown Packet Sets an alarm to go off when a packet cannot

be recognized by the DE285 as a known type.

AFD on Multiple Lines Sets an alarm that goes off when there is

more than one AFD packet in a single video ﬁeld.

No Video Sets an alarm that goes off when there is no

video signal or the video cannot be displayed.

Invalid V-Chip Rating Sets an alarm that goes off when the V-Chip

rating is not present or is not valid.

No Captions Sets an alarm that goes off when there is no

6101 VANC packet present.

Caption Pair Alarms

There are ﬁve alarms in the Caption Pair Alarms category that can be used to detect when certain combinations of caption channels are active.

Page 31

DE285 HD Caption Decoder/VANC Monitor

For each selected alarm, the two channels are checked over a 10 second period for data presence. If data is present in one channel but not the other, the alarm goes off.

Alarm Name Description CC1 && S1 Sets an alarm that goes off when there is a

mismatch between the presence of primary language SD captions and HD captions.

CC3 && S2 Sets an alarm that goes off when there is a mis-

match between the presence of secondary language SD captions and HD captions.

CC2 && S2 Sets an alarm that goes off when there is a mis-

match between the presence of secondary language SD captions and HD captions.

CC1 && CC3 Sets an alarm that goes off when there is a mis-

match between the presence of primary and secondary language SD captioning.

S1 && S2 Sets an alarm that goes off when there is a mis-

match between the presence of primary and secondary language HD captioning.

Error Alarms

There are three alarms in the Error Alarms category that can be used for speciﬁc troubleshooting.

Page 32

DE285 HD Caption Decoder/VANC Monitor

Alarm Name Description Video Frame Error Sets an alarm that goes off when there is an

error involving the video signal.

Caption Error Sets an alarm that goes off when a caption

error is detected. A complete list of caption errors can be found after this table.

XDS Error Sets an alarm that goes off when there is an

error involving the Extended Data Services packets.

VANC on Illegal Line Sets an alarm that goes off when there is an

error involving VANC on a different line than

what’s depicted in the SMPTE speciﬁcation Invalid ANC Packet Checksum

Sets an alarm that goes off when an invalid

ANC packet checksum is detected.

The following table lists each Caption Error and provides a short description.

Caption Error Description

CDP header not found The body of a VANC packet did not begin with

0x96 0x69, which marks the start of a CDP.

CDP footer not found The CDP footer section wasn’t found. Since

the footer includes the checksum, the de-

coder will not process such packets.

CDP sections out of order

The CDP should contain the following sec-

tions, in this order: a header, an optional

timecode section, an optional caption data

section, an optional caption service info sec-

tion, and a footer. If one or more of those was

out of order, you’ll see this message.

CDP sequence mismatch

The CDP header contains a 16-bit sequence

counter which should increment by one each

frame. If you see this, the sequence numbers

jumped between two VANC packets.

CDP header/footer sequence mismatch

The CDP footer contains a copy of the header

sequence counter; in this case, they were not

identical.

Page 33

DE285 HD Caption Decoder/VANC Monitor

Caption Error Description

CDP checksum error The CDP footer contains a checksum for the

entire CDP; if you see this, it didn’t match what the decoder expected.

CDP length mismatch The CDP header contains an 8-bit length

count; if you see this, the length didn’t match the number of bytes actually recovered.

CDP frame rate mismatch

The frame rate indicated by the CDP header doesn’t match the video. For example, you’ll see this if you capture VANC captions in 720p and play them back in 1080i.

Invalid CDP frame rate

The CDP frame rate was something nonsensical; for example, zero.

Wrong number of CC constructs

The CDP count of caption data pairs didn’t match what was actually recovered.

No line 21 captions No 608 data was found.

Bad line 21 alternation

In 720p, the 608 data are supposed to alternate between ﬁeld 1 and ﬁeld 2; this means that two consecutive frames of one or the other went by.

No line 21 ﬁeld X In 1080i, each frame is supposed to have ﬁeld

1 and ﬁeld 2 data for 608.

Line 21 not ﬁrst in packet

The 608 bytes are supposed to come ﬁrst in the caption data section of the CDP, before any 708 data.

Bad DTV triplet In the CDP caption data section, 708 data are

split into pairs and marked with 0xFF(start of a caption channel packet) or 0xFE(next part of a CCP). 608 data are marked with 0xFC(ﬁeld 1) or 0xFD(ﬁeld 2). The rest of the caption data section should be ﬁlled with pairs marked 0xF8, 0xF9, 0xFA or 0xFB. If a DTV triplet doesn’t begin with any of those markers, this message will appear; it might mean the DTV packets are misaligned.

Page 34

DE285 HD Caption Decoder/VANC Monitor

Caption Error Description

Unexpected DTVCC continue

DTV pairs marked 0xFE should only appear

after an 0xFF pair. (See "Bad DTV triplet" for

deﬁnitions.)

Valid DTV data after ﬁller

If a 708 service block doesn’t ﬁll the caption

data section, the remaining bytes should be

marked as ﬁller.

Caption channel packet sequence error

Caption channel packets have a two-bit se-

quence counter; this means that there was a

skip. This will usually happen at the same

time as CDP sequence mismatches; it’s un-

likely that one would skip and the other

wouldn’t.

Truncated caption channel packet

Caption channel packets aren’t allowed to

span multiple VANC packets.

Invalid null service block

A service block had service number zero but

non-zero length.

Multi-packet service block

A service block was too long to ﬁt in one

VANC packet.

Not deﬁning window X: too many rows

The FCC requires that decoders be capable

of displaying at least four rows. This effec-

tively means that any captioning with more

than four rows is not guaranteed to work on

all decoders. This message can be triggered

by a single window with more than four rows

or multiple windows whose rows add up to

more than four.

Caption text overﬂow The caption text can’t ﬁt in the current row;

some of it was dropped. This may happen if

certain commands(e.g., create a new window,

move to the next row) are lost.

5.7. OSD

The OSD tab allows for a fully customizable screen conﬁguration using the tools on the upper part of the OSD tab and a user speciﬁed audio monitor conﬁguration on the lower half of the screen.

5.7.1. Screen Conﬁguration

The upper part of the OSD tab provides a tool for customizing the screen conﬁguration by allowing the user to choose the presence and screen location of Caption Services, XDS data, AFD data, Audio Monitor, Audio Metadata and Errors/Alarms. The DE285 comes pre-loaded with several default layouts. To apply a default layout, use the pulldown menu next to Layouts to view the available options and choose the desired layout. If you are satisﬁed with the factory layout, click on the Apply to Screen button at the bottom of the Screen Conﬁguration section to load the selected layout.

To manually conﬁgure the screen there is a check box to the right of each data type’s name that can be checked in order to display the data, or unchecked to hide the data. To the right of the checkbox are the ’X’ and ’Y’ ﬁelds that control the horizontal and vertical positioning of the data, respectively. Both ﬁelds have a range of 0–100, with X=50, Y=50 signifying the center of the screen.

Page 36

DE285 HD Caption Decoder/VANC Monitor

The text size can also be speciﬁed for each data type by using the dropdown list in the size column to select the desired size. Below the checkboxes is the caption enabling section where you can choose an SD and HD service using the dropdown lists, as well as using the rightmost checkbox to enable or disable all captions. Once you are satisﬁed with the newly conﬁgured layout, click Apply to Screen to put the speciﬁed screen conﬁguration into effect, or Revert to discard any changes made and return to the last applied settings. The most recent layout applied to the screen is shown to the right of the Revert button for reference.

Page 37

DE285 HD Caption Decoder/VANC Monitor

5.7.2. Alarm/Error Conﬁguration

The middle section of the OSD tab allows the user to set the alarms and errors for OSD display. An explanation of setting these alarms and errors can be found in Section 5.6.2 .

Note: Alarms set in this manner will show up on the OSD and in log.

5.7.3. Audio Monitor Conﬁguration

The lower section of the OSD tab allows the user to customize the mapping of audio channels to the audio monitor. Using the four dropdown lists, you can select which audio channel pair you would like to map to which audio monitor pair. Below these dropdown lists you can specify a clip level in decibels in the range of 0 to -60 dB. To put changes into effect, click the Apply button at the bottom of the screen.

5.8. Settings

The Settings tab contains several subsections that allow the user to customize various aspects of the 285 website and screen conﬁguration.

5.8.1. Upgrade

The Upgrade subsection provides an easily accessible way to update the ﬁrmware that comes pre-installed on the DE285. The DE285 can be upgraded through the USB front panel as discussed in the System Setup Menu section or the upgrade can be performed through the website. Begin by downloading the most recent ﬁrmware update ﬁle from the EEG website or from the ’Download DE285 Upgrade’ link on the website and saving it to a location on your computer. After downloading the ﬁrmware upgrade, click on the Browse button to the right of the File

Page 38

ﬁeld, select the EEG ﬁrmware update and then click Submit to update the ﬁrmware.

5.8.2. System Settings

The Systems Settings subsection allows the user to restore the factory defaults on the box by clicking the Reset To Factory Defaults button.

Page 39

DE285 HD Caption Decoder/VANC Monitor

5.8.3. Alarm Settings

The Alarm Settings subsection allows the user to set a value in seconds that captions can be missing for before a GPIO alarm is triggered on pin

1. To change this value, enter a new value into the text ﬁeld and click the Apply button to update the No Captions Timeout. If you would like to see this alarm on the logging section of the website you must set the ’No Captions’ alarm by going to the Logging tab, clicking on the Logging

Options button and selecting the ’No Captions’ checkbox.

5.8.4. VANC Settings

The VANC Settings subsection provides a way to enable or disable passing VANC data through the box on the outputs. This option will prevent other decoders from double decoding the VANC on the video feed after the DE285.

5.8.5. Log Settings

The lower part of the Settings tab is the Log Settings subsection, which provides a way to set the date, time and time zone for accurate trigger and alarm logging. The current date, time, and timezone can be seen to the right of the Set Date/Time button. To change the Date/Time, simply use the dropdown menus to select the month, day and year and then set the local time and time zone that you are in. Alternatively, you can set the date and time by clicking on the Copy Computer’s Date/Time button, which uses the date and time from your current machine to set the date and time. When using this option be aware that the timezone is not copied along with the date and time information. To conﬁrm the settings, click the Set Date/Time button at the bottom of the Log Settings section. The triggers and alarms will now have the correct timestamp when viewed in the Logging module.
