Download from iTunes App Store 5

5

Download from iTunes App Store

The Dejero LIVE+ Mobile App is available for download from the iTunes App Store.

Launch the iTunes App Store and search for ‘Dejero’. Once the app is downloaded and

installed on the iPhone 4, iPhone 4S iPhone 5, iPad 2 or the new iPad go to the settings

app to make any necessary adjustments that are necessary.

Note: iPhone 4 is capable of Store and Forward Only – Live transmission from an

iPhone 4 is not possible.

App Settings

The Dejero LIVE+ Mobile App is designed to be simple and easy to use, however there

are a few settings that may need to be adjusted. These settings configure the video

output to match the broadcast environment and any station policies. Launch the

settings app and scroll down to the Dejero LIVE+ app to setup your app.

First set the camera output to either NTSC (30 fps) or PAL (25 fps) depending on your

broadcast region. As well set the format to either Wide Screen 16:9 or 4:3 aspect ratios.

There are three settings available for Live Streaming: if you would like to limit the

bandwidth of the stream to save on Cell Data usage set the Max BPS otherwise set to

Auto, which will use the all the available bandwidth for best picture quality. This setting

can also be used to limit the data rate in congested area with spotty Internet reception

– more on this in the troubleshooting section.

IFB Output can be turned off to save bandwidth when IFB output from the headphone

jack is not used.

In cases where the station sets the latency in the Portal for the Server, you need to turn

on the Preset Latency setting. This will disable the user setting of latency (1, 3, or 8

seconds) and only use the station Preset for the Server the iPhone is transmitting to.

Summary of updates since 2.0 6

6

Turn off Use Cell Radio to prevent the Dejero

LIVE+ app from using the cell radio. When this

setting is on the app will bond both the Wi-Fi

and cell connections.

By turning on the Autosave setting the Dejero

App will automatically save a copy of the video

in the camera roll on the iPhone after it has

been sent to a Dejero LIVE+ Broadcast Server

(Store and Forward mode).

Summary of updates since 2.0

- IFB Support added

- Improved Encoding algorithm

- Preset Latency added

- Confirm delete message when deleting a

clip that has been recorded

- Audio meter for microphone input

- Display server ingest name in Start

button when on air

- Improved error messages and status

- Native iPhone 5 and iPad resolutions

First time Launch 7

7

First time Launch

When the app is first launched it will prompt you for permission to use your current

location. Press OK to grant permission. This will send location information back to the

station. As well, the app requires access to your current location to use the Import

feature.

Next enter your assigned username and password to log into Dejero Dispatcher.

This username is not the same login used to access to Dejero LIVE+ Portal. The

dispatcher determines which station/server/ingest your iPhone will transmit to. This

assignment is done by the station operator in the Dejero LIVE+ Portal.

The username and password will only need to be typed in once, the Dejero LIVE+ app

will remember your username and password and automatically log you in when the app

is launched again.

Camcorder View Screen 8

8

Camcorder View Screen

The main screen or view on the Dejero LIVE+ mobile app is designed to look and feel like

a traditional camcorder view screen. At all times, before and during live transmission or

recording you can view exactly what your video will look like. This allows you to

properly frame the scene before going on air or recording.

All of the functionality of the application can be accessed from the 6 buttons on the

screen. The top three buttons will start/stop and control the camera on the device. The

bottom right button sets the mode of operation. There are three modes of operation –

live transmission, record a video or import a video from the devices camera roll.

The bottom left bottom allows you to adjust the settings for either live mode or

recording mode. The context of this button will change according to which mode (either

live or record) the app is performing.

Note: the flash light on/off button will not be present when a camera (the front camera

on an iPhone) is selected that does not have a flash, or on the iPad which does not have

a flash light for either camera.

At the very bottom left corner of the screen is the ‘reveal’ clip manager button. The clip

manager allows you to manage and view the status of any pre-recorded video that is

being sent to the server. The clip manager screen will slide up and cover the camcorder

viewfinder screen.

Live Transmission 9

9

At the top of the screen is the device’s status bar. This status bar will indicate the signal

strength of Wi-Fi/cell connections, the current time, and the battery charge level. This

information is available at all times.

Live Transmission

Note: The iPhone 4 device is not capable of live video transmission. Live transmission

requires an iPhone 4S, iPad 2 or the new iPad.

The Dejero LIVE+ Mobile App is capable of transmitting live video/audio anywhere cell

connectivity or Internet is available via Wi-Fi. As well, the app can bond, or use both Wi-

Fi and cell radios simultaneously, creating a more reliable video transport.

Select Live mode with the Operations mode button, the settings button on the bottom

left allows you to select the delay or latency of the video transmission. A short delay of

1.5 seconds allows operation where the iPhone operator can interact with the studio.

However, a short delay also decreases the amount of time that the app can do any error

correction in case of cell network congestion – which can result in loss or stuttering of

the video.

As a general rule of thumb, a delay of 3.0 seconds provides a compromise of short delay

for interaction with the studio and enough time to correct any problems with network

Live Transmission 10

10

congestion. For maximum reliability, where interaction is not required, set the delay to

8.0 seconds.

When the app is set to use the Preset Latency, this control is grayed out and displays

“Preset”

Going on Air 11

11

Going on Air

Press the Start button to ‘Go On Air’. The app will enter a ‘Starting’ phase. During this

phase the app will retrieve the current assignment (which Server and ingest to transmit

to) and negotiate a connection with the Server. During this starting phase there are

several possible errors that may occur, preventing going on air.

In case of transmission error an alert box will open indicating the cause of the error.

The condition must be corrected in order to go on air. Some of the error conditions are:

Device has not been assigned a server output. An iPhone must be assigned a Server

output to transmit the live video to. This is done by the station manager with the

Dejero LIVE+ Portal.

Server in use. The iPhone is attempting to transmit video to a Server that is currently in

use already. The iPhone needs to be assigned to another Server or wait until the Server

currently assigned in not in use.

No Internet Connectivity. The iPhone is not connected to the Internet. You can double

check the connectivity by attempting to surf the Internet on the Safari web browser.

Bandwidth Testing Phase 12

12

Unsupported Video Format. The server reported that it did not recognize the video

format that the iPhone was trying to transmit. The cause of this error is either an

incorrect NTSC/PAL setting or the server is running a version of the software that does

not recognize the video formats that the iPhone produces. The current minimum

version that should be running on the Server is 2.6.1.6701.

Server not responding. The iPhone attempted to connect to the Server but got no

response. First, test that the Server is online and functioning; this can be done in the

portal with the ‘Ping’ test. If the Server is online and functioning then follow the

diagnostics guide for setting Server IP addresses.

All ingests are in use. The iPhone has been assigned to a pool of Server ingests and all

of the ingests are currently in use by other iPhones/transmitters. The user will need to

wait until an ingest is free to be able to transmit.

Bandwidth Testing Phase

If the app passes the initial connectivity tests, next it will enter the bandwidth-testing

phase. During this phase the app will probe the characteristics of the Wi-Fi and/or cell

connections. Both the available and bandwidth and latency of the signal are tested.

Broadcasting Live 13

13

During this Testing phase you’ll see a graphical overlay showing the bandwidth (in

translucent white) and latency as a blue line. If one of the connections is not available

you’ll see the bandwidth as 0 kbps.

Broadcasting Live

While broadcasting live, the ‘Start’ button will change to ‘On Air’ and the colour will

change to green. The front/back camera toggle button can be used to switch from the

back camera to the front and vice versa. As well, if available, the flash can be turned on

and off.

In the left corner of the video display is an IFB badge. This badge will be displayed when

IFB is turned on and available from the server. The right corner of the video display

shows a VU meter for the microphone input.

Along the bottom of the screen the app will display some statistics showing how well

the transmission is performing. The first number on the left is the video encoder rate in

bits per second, the higher the number, the better the quality. Generally the ranges of

quality can be mapped out as:

0-200 kbps – very poor quality or possible no video signal

Errors While Broadcasting 14

14

200-750kbps – low quality, but suitable for ‘head shots’ with little motion

750kbps – 1500kbps – medium quality, suitable for motion

1500kbps – 2200kbps – high quality video

2000kbps and above – excellent quality video

The number next to the video encoder rate is the current delay or latency of the signal.

This is the setting that you applied before going on air and doesn’t change.

Beside the latency, is a bar graph showing the relative strengths of the cell and Wi-Fi

connection when using bonded transmission (this graph does not appear when using

only a single connection). A long black bar indicates that the connection is good and has

enough bandwidth to produce a high quality video signal. A shorter bar means the

bandwidth on that connection is less than high quality. Since the app will bond both the

cell and Wi-Fi connections, two shorter bars can produce a high quality video signal.

In the bottom right corner is a time clock indicating how long the app has been

broadcasting live video.

Errors While Broadcasting

If there are any errors while broadcasting live a yellow status band will appear on the

bottom of the screen indicating the type of error that occurred.

Going Off the Air 15

15

When the error clears the yellow band will disappear. Some of the error messages that

can occur during live broadcast are:

Not enough bandwidth to transmit. No video or audio is being broadcast because the

connectivity connections are too poor. Finding a different location with better cell

coverage is a suitable resolution.

No Internet connectivity. The app has lost all Internet connectivity. Relocating to a

different location and restarting the broadcast is a suitable resolution.

Latency of signal too high. There is enough bandwidth available, however the latency

or delay of the broadcast is too high to transmit in the current delay setting. This error

will occur if the app is set to a low delay (1.5 seconds or 3.0 seconds) and the network

conditions are too poor to transmit video at that setting. Restart the transmission at a

longer delay is a suitable resolution.

Going Off the Air

Press the green ‘On Air’ button (previously labeled ‘Start’) to stop transmitting live and

go off the air. The app will stop transmitting and notify the Server and the Dejero LIVE+

Portal that it is going off the air. This phase will take about 2 seconds and the button

Store and Forward 16

16

will be labeled ‘Stopping…’ during this phase. When the stopping phase is completed

the app will reset back to the main camcorder screen.

Store and Forward

Besides transmitting live video, the Dejero LIVE+ Mobile App features the ability to

record video and send this recorded video to the Dejero LIVE+ Broadcast Server at a

later time. Using this technique a high quality video can be recorded when network

conditions are too poor to transmit live and then uploaded later.

As well a video can be imported from the device’s camera roll and uploaded to the

Dejero LIVE+ Broadcast Server. The video could be recorded or edited with another app

using this technique.

To change modes from Live transmission to Record or Import press the Operation mode

button in the bottom right corner of the screen.

Recording a video

Review, Send, Save or Delete 17

17

When the app is in record mode, the lower left settings button allow you to set the

encoding rate of the recording video – 2.0Mbps (low), 4.0Mbps(medium), 6.0Mbps

(high). The higher the encoding rate, the better quality recording and the longer it will

take to upload the file to the Dejero LIVE+ Broadcast Server.

Press the Start button to begin recording video. While the app is recording you can use

the camera control buttons to switch the front and rear cameras, and turn the torch

light on/off.

While the app is recording video the ‘Start’ button label will change to ‘Recording’ and

the colour of the button will turn green. In the bottom right corner a timer will start

indicating the recording duration. Press the ‘Start/Recording’ button again to stop

recording.

Review, Send, Save or Delete

Immediately after recording the video the app enters a phase where you can review the

video. On the bottom of the screen are playback controls that allow you to pause,

rewind, scrub the video. The audio will play out the device’s speaker.

Sending video 18

18

Along the top of the screen are three options. You can send the video to the Dejero

LIVE+ Broadcast Server, save the video the camera roll or delete the video. Choosing

save to camera roll allows you to export the video so it can be edited by an external app

(such as the Avid Video Editor).

Sending video

Pressing the send button on the screen, will start the send operation. A thumbnail of

the video (for easy identification in the Store & Forward portal) is generated, as well as

other meta data. The clip manager screen will slide up and the sending of the clip will

start.

If the cell radio is enabled in the Settings panel, the app will bond both the Wi-Fi and the

Cell connections and send the video as quick as possible. Sending will continue in the

background, you can record another video or even go live (the send will be temporarily

paused during live transmission).

Clip Manager

The clip manager screen allows you to monitor the sending of clips, pause the sending of

clips and deleting of clips being sent.

Clip Manager 19

19

On the left side of the screen are some status items – the server the files are being sent

to, the upload speed in kilobits per second and the estimated time and total bytes

remaining for clips being uploaded.

On the right side of the screen is a list of clips being sent. A thumbnail representation of

the video identifies the video, a progress bar shows how much of the video clip has

been sent and each clip has a status button that indicates the status of the clip being

transferred. There are four possible status states:

Sending. The clip is currently being sent. Only one clip at a time will be in the sending

state.

Queued. The clip is queued to be sent after the clips above have been sent.

Complete. The clip transfer has been completed and is available on the Server for

playback. Only complete clips can be played, partially transferred clips are not playable

on the Server.

Paused. Clip transfer has been paused by the user. At any time the clip is in the

Sending or Queued state you can press the status button to pause the clip. Pausing a

clip transfer is a means to prioritize a particular clip for transfer, by pausing the clips that

Importing clips 20

20

are ahead (above in the list) in the Queue. Pressing the status button while a clip is

paused will start the transfer for that clip again.

The screen shot above shows the top clip ‘Paused’. The clip below immediately goes

from Queued to Sending, thus transferring the second clip before the first.

Deleting clips

To delete the clip from the clip manager swipe your finger over the clip from left to

right. The status button will change to a Delete button. Tap the Delete button to delete

the clip from the clip manager. Or tap anywhere else to cancel the delete operation.

Dismissing the Clip Manager

Press the dismiss button in the top right corner of the screen to close the clip manager.

The app will return the main screen where you can record another clip or go live on air.

This can be done while clips are being sent to the Server.

Importing clips

Dejero LIVE+ requires Location Services enabled to import21

21

Clips can be imported from the camera roll and sent to the Server. Press the Operation

mode from the main screen and select Import. A clip selection screen will slide up

allowing you to select 1 or more clips from the camera roll. Note: only video clips will be

shown; pictures cannot be selected and sent to the Dejero server.

Tap the thumbnail representation of the clip to select it. A green checkmark will appear

in the lower right corner indicating the clip is selected. Tapping a selected clip will

deselect the clip. Press the Done button in the top right corner when you have finished

selecting the clips to import. Note: if no clips are selected, pressing Done will cancel the

Import Operation.

Review, Send or Cancel

After pressing the Done button the app will allow you to review the clips you have

selected. Playback controls to pause, rewind and scrub the clips. If more than one clip

was selected, the clips will be played one after another. Press the send button to start

sending the clips, or press the Cancel button to cancel and return to the main screen of

the app.

Dejero LIVE+ requires Location Services enabled to import

Dejero LIVE+ requires Location Services enabled to import22

22

If the app does not have Location Services enabled (access to the GPS) and access to the

Photo Library then the Import operation will not function. An error message will appear

when the Import button is pressed – “Dejero LIVE+ requires Location Services enabled

to import video”

For iOS 5.1

To enable the import feature, Location services must be enabled for the Dejero LIVE+

Mobile App. Go to the Setting App, select Location Services (in the top group), then

scroll down to Dejero LIVE+ and set the toggle switch to On.

For iOS 6.0 or later

To enable the import feature, go to the Settings app, select Privacy. Make sure Location

Services is On and the Dejero App is also On.

Then select Privacy->Photos and make sure Dejero LIVE+ is also on.

Left or Right handed operation 23

23

Other Features

The following are a list of features that are available in all modes of operation.

Left or Right handed operation

The front and rear cameras on the iDevice are located on one side of the device. Left

handed or right handed users may find it more convenient to hold the device such that

their hand does not block the cameras. The user interface will automatically rotate for

left or right-handed operation.

Tap to focus

Tapping the screen can focus the rear-facing camera. The front facing camera is a fixed

focus camera and is always in focus. As well, when the camera is switch from the front

facing camera to the rear-facing camera the camera is automatically focused.

Auto start of sending clips

When the app is first launched it will scan for any clips in the clip manager that have not

been sent to the server. If unsent clips are found, it will automatically start sending

clips. Pause any clips to disable that clip from automatically being sent.

As well, if clips are being sent and a live transmission is started, the clip sending is

temporarily suspended. After going off air, the clip sending is automatically started

again.

Other Audio Topics 24

24

IFB Audio and other Audio topics

In order to access IFB on the iPhone, the server must be configured with IFB – the

process is exactly the same as configuring the server for IFB to a 20/20 Transmitter.

IFB will only play out the 3.5mm headphone jack on the iPhone. You can use either the

headphone/microphone ear buds that come with the iPhone or use a splitter that allows

a headphone/earphone and an external microphone to be connected to the 3.5mm

jack.

IFB will not play out the speaker of the iPhone.

IFB Output starts immediately after the Start button is pressed and the iPhone has

connected to the server. It will play output during the Bandwidth Testing phase and

while on air. IFB is continuous even during low latency error messages while

broadcasting.

Other Audio Topics

The iPhone captures audio at 24K samples per second and encodes the audio at 56Kbps

mp3 audio. Best performance in audio can be achieved with a professional external

microphone connected to the 3.5mm audio jack on the iPhone. Audio is more suited to

voice rather than musical audio.

Incoming IFB audio is encoded in low latency speex codec with is tuned for voice type

audio. Musical IFB audio is not recommended.

VU Meter feedback

New with version 2.3 is the VU meter on the camcorder display of the app. This VU

meter shows a pseudo accurate level of microphone input. More bars are better.

Troubleshooting guide

iPhone app gets stuck in the Starting… phase

During the starting phase of live transmission the iPhone will get the assignment from

the portal and do a time synchronization with the Server. If the latency of the

transmission is too great or varies greatly it may take a long time to complete this

phase. Possibly remedies are:

- set the latency to 8.0s or use a preset that is longer than 8.0s and retry

transmission

- Try transmitting at a alternate location where cell connectivity is better

- Bond Wi-Fi + cell (possibly using a Mi-Fi hot spot with another carrier)

- Make sure your iPhone is up to date with the latest version

- Use Store and Forward and record a clip to be transferred at another time when

connectivity is better

iPhone app gets stuck in the Testing… phase

During the testing phase of live transmission the iPhone is probe and negotiate a

transmission rate with the Server. If the latency of the signal is too great or varies too

much then a longer than expected testing… phase will occur. Possible remedies are:

- set the latency to a higher setting to compensate for the varying conditions

- bond Wi-Fi + cell

- Set the maximum bps from Auto to a lower setting. This will improve conditions

where a Wi-Fi/cell tower is buffering packets but unable to pass these packets on

to the internet in a timely manner.

- Restart transmission in an alternate location where connectivity is better

All other trouble shooting

Perhaps the most important thing to remember when troubleshooting the Mobile App,

is that all the same troubleshooting steps that apply to the 20/20 Transmitter also apply

to the app. The iPhone app runs the same CORE code as the 20/20 Transmitter and

requires the same setup and conditions as the 20/20. Treat the iPhone app as a 20/20

when troubleshooting any connectivity or transmission problems.
