1 Introduction The Datavideo NVS-34 is a video streaming server designed for various network environments, offering you multiple bitrate settings as well as the flexibility of streaming and recording either individually or simultaneously. From any SDI/HDMI input sources, the Datavideo’s video streaming server generates an H.264 encoded stream that is compliant with RTSP or RTMP(S) protocols. Additionally, you can also connect an external RCA Unbalanced Audio source to the NVS-34.
- Google Chrome Streaming Video streaming protocols are RTSP, RTMP, RTMPS, TS, and HLS supported by the following: - Adobe Media Server and Wowza Media Server. - Video Players such as VLC. - Content Delivery Networks such as Youtube Live. Recording Records MP4 or TS file to an SD card formatted to NTFS or FAT32 file system. 1.
2 Connections and Control In this section, we will show you how you can operate the device as well as the device setup. 2.1 Front Panel Power Switch Turn on/off the device. SD Card Slot The SD Card Slot allows insertion of an SD Card for video recording. INPUT Button Press the INPUT button to select between SDI and HDMI input sources. The button is always in solid white. The activated input source will be indicated by the corresponding LED.
Push and hold one of the RECORD and STREAM buttons until the pushed button starts blinking red. As soon as the pushed RECORD or STREAM button is released, the BITRATE button will turn solid red. While the BITRATE button stays solid red, push it to switch between different bitrate modes (H, M or L). Please note that the BITRATE button will return to solid white after a few seconds if button push is not sensed. To exit, push the the RECORD or STREAM button again.
STREAM Button The STREAM button activates and deactivates the STREAM Only mode; follow the steps outlined below: Start streaming When idle, the STREAM button is solid white. Press and hold the STREAM button for approximately 2 seconds. When the stream function is activating, the STREAM button turns from solid white, then blinking red and finally to solid red. When the STREAM button turns solid red, this indicates that the record function has been successfully activated.
Audio Input RCA Unbalanced Audio Input Connect an unbalanced stereo audio source for streaming and recording. Video Input HDMI Input Connect an HDMI video source. SDI Input Connect an SDI video souce. Network LAN The LAN port connects the device to the Internet via an Ethernet cable. Power DC IN 12V DC in socket connects the supplied 12V PSU. The connection can be secured by screwing the outer fastening ring of the DC In plug to the socket.
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.
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.
6. 7. 8. The reset is complete as soon as you see the BITRATE, VERTICAL, RECORD and STREAM buttons illuminating solid white. The device’s network settings should now be the default DHCP mode. 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.
3.2 On the command prompt, enter ipconfig/flushdns followed by ipconfig/release and ipconfig/renew. 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.
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.
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.
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.
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.
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. Level ID Max. Video Bitrate in kbits/s Max Frame Size in macroblocks 1.0 64 99 Max decoding speed in macroblocks per second 1485 1b 128 99 1485 1.
Level ID 4.1 (FHD) Max. Video Bitrate in kbits/s 50000 Max Frame Size in macroblocks 8192 Max decoding speed in macroblocks per second 245760 Resolution, Frame Rate (Max Stored Frames) 2,048×1,024@30.0 (4) 1,280×720@68.3 (9) 1,920×1,080@30.1 (4) 2,048×1,024@30.0 (4) Entropy There are two coding options available for generating H.
5 3 2 1 Record Mode 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.
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.
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.
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.
Level ID Max.
