3 Video Streaming

In this section, we will show you how to set up and start your video streams.

3.1 Streaming Network Connection and Device Search

Let's first detail how to connect the NVS-34 to a network with or without a DHCP server, and acquire the NVS-34's IP address.

Note: The device is DHCP enabled by default.

Connecting to a DHCP Network (DHCP Mode)

Follow the procedure below to scan your DHCP network for connected NVS-34 devices.

Note: The NVS-34 will be automatically assigned an IP address upon connection to the DHCP network.

1. Connect the NVS-34's LAN port to the network via an Ethernet cable.
2. Turn on the NVS-34's power, which should boot up the device in DHCP mode by default.
3. On your laptop, download the free IP Finder utility program from the product page https://www.datavideo.com/product/NVS-34.
4. Connect the laptop to the same network that the NVS-34 is connected to and double click the IP Finder utility program icon.
5. On the IP finder interface, click the SCAN button to start searching for connected devices.

Connecting to a NON-DHCP Network (Static IP)

Upon connection to a non-DHCP network, the NVS-34 will not be assigned of any IP addresses. As such it is recommended that you manually assign a fixed IP address to the device or use the default IP address (192.168.1.200).

Fixed IP is primarily used in point-to-point connection, such as directly connecting the PC to the NVS-34. In a non-DHCP environment, the NVS-34 only works in fixed IP mode. To set the NVS-34 to a fixed IP or the default IP, please follow the steps outlined below:

1. Connect the NVS-34's LAN port to the network via an Ethernet cable.
2. Turn on the NVS-34's power, which should boot up the device in DHCP mode by default.
3. Search for the NVS-34 device according to the method detailed in the previous DHCP section. Once found, log in to the user interface on the web browser.
4. Open the system page by clicking the "System" tab on the home of the user interface.
5. In the "Network Setting" pane, disable the DHCP mode.
6. You will then be allowed to manually enter the static IP address once the DHCP mode is disabled. The default static IP is 192.168.1.200 or you can also enter an IP of your preference. The subnet mask and default gateway are 255.255.255.0 and 192.168.1.254 respectively.

Device Reset

In Fixed IP mode, if you forget or lose the IP address, do the following to reset the device settings.

1. Power cycle NVS-34.
2. During device bootup, the BITRATE, VERTICAL, RECORD and STREAM buttons should illuminate solid red.
3. The device bootup should be complete approximately after 30 seconds and the BITRATE, VERTICAL, RECORD and STREAM buttons will turn solid white.
4. Simultaneously press and hold the RECORD and STREAM buttons until the BITRATE, VERTICAL, RECORD and STREAM buttons turn red.
5. Wait for about 5 seconds then release the RECORD and STREAM buttons and the BITRATE, VERTICAL, RECORD and STREAM buttons should start blinking red.

1. The reset is complete as soon as you see the BITRATE, VERTICAL, RECORD and STREAM buttons illuminating solid white.
2. The device's network settings should now be the default DHCP mode.
3. Connect the device to a DHCP network and use the IP finder to scan for the device.

Troubleshooting the Network Connection

Connect the NVS-34 to the network and open the IP Finder utility program. Scan for the device. If not found, it is possible that your network is not assigning IP addresses.

Reasons of this are outlined as follows:

• Router or DHCP server is not responding to the device's request.
• New devices are blocked by the network administrator.
• Anti-virus software or the firewall blocks the communication.

Solve the problem by attempting the following:

• Turn off the router, wait for 10 seconds then turn on the router again.
• Reset the NVS-34 to the factory defaults (see the previous section for device reset).

If the problem still persists, try the following:

• Temporarily shut down the anti-virus software or firewall.
• Make sure no other devices are connected to the LAN (wired or wireless) because this may result in IP conflicts.

Advanced Troubleshooting

If you still are unable to connect, try the following:

• Use the ARP table to search for the device's MAC address which can be found on the print label at the bottom of your NVS-34.
• MAC address starts with 00:07:36:03:xx:xx.
• On the command prompt (terminal on MAC OS), enter "arp -a" then press enter key to display an ARP list. See if the NVS-34 is successfully connected to the network.
• Execute services.msc, and on the right column of the "Services" window, locate "DHCP Client" then click "Restart".

- On the command prompt, enter ipconfig/flushdns followed by ipconfig/release and ipconfig/renew.

3.2 Web User Interface

By now, we have obtained the IP address of the NVS-34. To open the web user interface, either double click the device's IP on the IP finder or enter the device's IP into the address bar of a web browser then hit the ENTER button. Log in by entering the username as well as the password into the pop-up dialogue box as shown below.

• Username: admin
• Password: 000000

Click OK to log in.

Source

You will see the Source page immediately after logging into the web UI, on which first select the video source, SDI or HDMI.

If you've selected SDI, you only need to select the audio source next. The available audio source options are Embed, Line-In and Mixer. Descriptions of which are outlined as follows:

• Embed: SDI embedded audio
  • Line-In: External audio from RCA AUDIO IN jacks
• Mixer: A mix of SDI and HDMI embedded audio as well as RCA AUDIO IN

If you've selected HDMI, you will be allowed to adjust the source video's brightness, contrast, hue and saturation by dragging the corresponding sliders as shown in the diagram below. After that, select your audio sources. You may choose to output HDMI embedded audio (Embed), external audio from RCA AUDIO IN jacks (Line-In), or a mix of SDI and HDMI embedded audio as well as RCA AUDIO IN (Mixer).

At the bottom of the page, you will be able to view video and audio source information such as Input Information, Video Source, Audio Source, Resolution, Frame Rate, Channels, Bits Per Sample and Sample Frequency.

Note: The NVS-34 web UI does not update automatically so to learn the latest device status, please refresh the page manually.

While monitoring streaming and recording, please update the page periodically regardless of how you operate the device (using the device's physical buttons only or using the device's physical buttons along with the web UI). This ensures the page is always displaying the most up-to-date information.

Operation Mode

Click the Operation Mode tab on the tool bar to open the operation mode configuration page on which the user will be allowed to customize various stream and record settings.

The NVS-34 offers the following operation modes:

• Stream
• Record

which will be discussed in detail in this section.

Stream Mode

The NVS-34 has two stream engines allowing you to stream to two different destinations over multiple protocols such as RTSP, RTMP, TS and HLS. See Section 3.3 for instructions on each individual stream setup.

The configurable stream video settings are Encoder Source, Stream Type, Resolution, Frame Rate, Profile, Level, Entropy, GOP and Video Bitrate (bps) which will be described later in this section.

Note that once your video streams are set up, click "Apply" button to apply the new stream settings. Click "Start Stream" to open the stream and "Stop Stream" to end the stream. To reset, simply click the default button.

Next, we will discuss the stream setting options in greater detail.

Encoder Source

This option allows you to enable the stream encoder for configurations of various parameters. If the stream encoder is not needed, disable this option.

Stream Type

The NVS-34 offers the user four stream types which are RTSP, RTMP, TS, and HLS. Parameters of each individual protocol will be briefly described below.

RTSP (Real Time Streaming Protocol)

• RTSP Port: The RTSP port number ranges from 554 to 562 and is 554 by default.
• RTSP HTTP Port: The RTSP HTTP port number ranges from 8553 to 8563 and is 8554 by default.
• Account / Password: The RTSP streaming account credentials which are root/root by default.
• Session Name: The default RTSP session name is session0.mgp.

RTMP (Real-Time Messaging Protocol)

• RTMP URL: Enter an RTMP URL obtained from any live streaming platform such as Youtube.
  Note: The NVS-34 supports RTMP Publish only and not RTMP Local.

• Stream Name: Enter a stream name or key from any live streaming platform such as Youtube.

• Account / Password: Enter the account name and the password of your RTMP platform account.

TS (Transport Stream)

- TS URL: Enter a URL for your transport stream.

Please note that when streaming, the NVS-34 converts video into data, which are sent across an IP network. High bitrates consume more bandwidth across the IP network. In a gigabit office LAN, high bitrate may not be a concern and Speed/Bandwidth is therefore not a limitation in an NVS-34 application environment.

If your available bandwidth is limited, you should reduce both your resolution and your bitrate accordingly. A good rule of thumb is for the bitrate of your stream to use no more than 50% of your available upload bandwidth capacity on a dedicated line. For example, if the result you get from a speed test shows that you have 2Mbps of upload speed available, your video bitrate should not exceed 1Mbps.

Resolution

The first step of encoder setup is to adjust the image size. It is best to either match your original video source or scale it down. For example, capture at HD 720 and stream at HD 720, or capture at HD 720 and stream at 540 (high).

You should never be scaling up and streaming at a higher resolution than your original video source. For example, it does not make sense to capture at 720 and stream at 1080. Note that you will also have no gain in quality and you are using more bandwidth than is necessary for your viewers.

You should also be aware that higher resolutions require greater processing power to encode the stream. Attempting too high of a resolution on too little processing power can result in degraded image quality and corrupted or interrupted streams or recordings.

Resolutions available for the stream encoder are listed as follows:

• 1080x1920
• 720x1280
• 576x720
• 480x720
• 480x640
• 240x320

Frame Rate

Select a frame rate from the drop-down menu for video streaming. Note that frame rates should always match the frame rate of the video source.

• 60.00
• 50.00
• 30.00
• 25.00
• 20.00
• 15.00

Video Bitrate (bps)

The bitrate of the video specifies the amount of information stored in the video. The higher the bitrate is, the clearer the video is. However, when choosing your encoder settings for streaming, you should first check your available upload bandwidth. A good rule of thumb is for the bitrate of your stream to use no more than 50% of your

available upload bandwidth capacity on a DEDICATED line. For example, if the result you get from a speed test shows that you have 2Mbps of upload speed available, your combined audio and video bitrate should not exceed 1Mbps.

Usually high bitrate means good image quality; however, there are also exceptions. For example, SD video may appear acceptable at 1000 Kbps (1M) but HD video is unacceptable at 1000 Kbps.

Available video bitrates are listed as follows:

The Encoder Mode sets the video bitrate mode for your video stream. The available modes are listed as follows:

• High (8M)
- Medium (4M)
- Low (2M)

Tip: You can also switch between different bitrate modes by pressing the Bitrate button on the front panel. See Section 3.4 for details.

Profile

Profile sets the H.264 encoding profile for your stream. The available options are Baseline, Main, and High. Typically, High profile provides the best image quality and is suitable in most instances. However, depending on the decoder used when viewing the stream, such as with mobiles devices, a Main or Baseline profile may be required.

• High
• Main
• Baseline

Level

Levels specify the size of the video a decoder must be able to handle. They specify a maximum bit-rate for the video and a maximum number of macroblocks per second. Level numbers range from 1 to 5 with intermediate steps (e.g., 1.1, 1.2, 1.3 and etc). The table below provides a summary of maximum parameters supported by each H.264/AVC level.

Entropy

There are two coding options available for generating H.264 content:

• CAVLC (Context-Adaptive Variable Length Coding)
  • CABAC (Context-based Adaptive Binary Arithmetic Coding)

CABAC encoding provides a 7-10% quality improvement over CAVLC but requires an extra 10-15% CPU. CABAC encoding is only available in H.264 Profiles Main & High. When targeting at low-powered devices, such as older cell phones and tablets, we recommend the Baseline Profile that uses CAVLC which requires less computing power.

GOP

GOP pattern with longer GOP length encodes video very efficiently. Shorter GOP lengths usually work better with video that has quick movements, but they do not compress the data rate as much. Depending on your applications, you can select 16 GOP sizes ranging from 1 to 255.

The NVS-34's record engine allows you to record your program on the SD card. See Section 5 for a list of recommended SD cards. The record parameters shown in the diagram below will be discussed in detail in this section.

Note that after you've configured the record settings, click "Apply" to apply the new record settings. Click "Start Record" to start recording and "Stop Record" to end recording. To reset, simply click the default button.

Encoder Source

This option allows you to enable the record engine for configurations of various recorder parameters. If the recorder is not needed, disable this option.

File Name

Enter the name of your record file.

Resolution

Recording resolution is the number of pixels (dots) used to create an image. Higher resolutions use more pixels to create an image. This means that greater amounts of detail can be expressed in the image, but larger files sizes and a greater amount of storage (i.e. hard drive space) are required to save the images or video.

Resolutions available for your recorder are listed as follows:

• 1080x1920
• 720x1280
• 576x720
• 480x720
• 480x640
• 240x320

Frame Rate

Select a frame rate from the drop-down menu for video recording.

• 60.00
  • 50.00
  • 30.00
  • 25.00
  • 20.00
  • 15.00

Frame rate greatly impacts the style and viewing experience of a video. Different frame rates yield different viewing experiences, and choosing a frame rate often means choosing between things such as how realistic you want your video to look, or whether or not you plan to use techniques such as slow motion or motion blur effects.

Below is a list of common options for different applications:

- 24fps – This is the standard for movies and TV shows, and it was determined to be the minimum speed needed to capture video while still maintaining realistic motion.

• 30fps – Videos with a lot of motion, such as sports, will often benefit from the extra frames per second.
• 60+fps – Anything higher than 30fps is mainly used to create slow motion video or to record video game footage.

Video Bitrate (bps)

The bitrate of the video specifies the amount of information stored in the video. The higher the bitrate is, the clearer the video is.

Available video bitrates are listed as follows:

Recommended video bitrates

• 720P or lower - 8 - 10 mbps
• 1080P or higher – 15 mbps or higher

Encoder Mode

The Encoder Mode sets the video bitrate mode for your recording. The available modes are listed as follows:

• High (8M)
• Medium (4M)
• Low (2M)

Tip: You can also switch between different bitrate modes by pressing the Bitrate button on the front panel. See Section 3.4 for details.

Profile

Profile sets the H.264 encoding profile for your recorder. The available options are Baseline, Main, and High. Typically, High profile provides the best image quality and

is suitable in most instances. However, depending on the decoder used when viewing the recording, a Main or Baseline profile may be required.

• High
• Main

- Baseline

Level

Levels specify the size of the video a decoder must be able to handle. They specify a maximum bit-rate for the video and a maximum number of macroblocks per second. Level numbers range from 1 to 5 with intermediate steps (e.g., 1.1, 1.2, 1.3 and etc). The table below provides a summary of maximum parameters supported by each H.264/AVC level.
