So when multiple clients access the AXIS 213’s Live View page, it is necessary to queue the users and restrict the length of time they are in control of the Pan/Tilt/Zoom controls. Use the buttons to request or release control of the Pan/Tilt/Zoom controls.

The Pan/Tilt/Zoom Control Queue is set up by the administrator under

PTZ Configuration > Control Queue.

AXIS 213 - Video and Audio Streams 13

Video and Audio Streams

The AXIS 213 provides several different image and video formats. The type to use depends on your requirements and on the properties of your network.

The Live View page in the AXIS 213 provides access to Motion JPEG and MPEG-4 video streams, as well as to single JPEG images. Other applications and clients can also access these video and audio streams/images directly, without going via the Live View page.

Video Stream Types

Motion JPEG

This format uses standard JPEG still images in the video stream. These images are then displayed and updated at a rate sufficient to create a stream that shows constantly updated motion.

The Motion JPEG stream uses considerable amounts of bandwidth, but also provides excellent image quality and access to each and every individual image contained in the stream.

Note also that multiple clients accessing Motion JPEG streams can use different image settings.

MPEG-4

This is a video compression standard that makes good use of bandwidth, and which can provide high-quality video streams at less than 1 Mbit/s.

The MPEG-4 standard provides scope for a large range of different coding tools for use by various applications in different situations, and the AXIS 213 provides certain subsets of these tools. These are represented as Video object types, which are selected for use with different viewing clients. The supported video object types are:

•Simple - sets the coding type to H.263, as used by e.g. QuickTime™.

•Advanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC (AXIS Media Control)

When using MPEG-4 it is also possible to control the bit rate, which in turn allows the amount of bandwidth usage to be controlled. CBR (constant bit rate) is used to achieve a specific bit rate by varying the quality of the MPEG-4 stream. When using VBR (variable bit rate), the quality of the video stream is kept as constant as possible, at the cost of a varying bit rate.

14 AXIS 213 - Video and Audio Streams

Notes: •MPEG-4 is licensed technology. The AXIS 213 includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.

•All clients viewing the MPEG-4 stream must use the same image settings.

MPEG-4 protocols and communication methods

To deliver live streaming video over IP networks, various combinations of transport protocols and broadcast methods are employed.

•RTP (Realtime Transport Protocol) is a protocol that allows programs to manage the real-time transmission of multimedia data, via unicast or multicast.

•RTSP (Real Time Streaming Protocol) serves as a control protocol, to negotiate which transport protocol to use for the stream. RTSP is thus used by a viewing client to start a unicast session, see below.

•UDP (User Datagram Protocol) is a communications protocol that offers limited service for exchanging data in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP). The advantage of UDP is that it is not required to deliver all data and may drop network packets when there is e.g. network congestion. This is suitable for live video, as there is no point in re-transmitting old information that will not be displayed anyway.

•Unicasting is communication between a single sender and a single receiver over a network. This means that the video stream goes independently to each user, and each user gets their own stream. A benefit of unicasting is that if one stream fails, it only affects one user.

•Multicast is bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of information to multiple network users. This technology is used primarily on delimited networks (intranets), as each user needs an uninterrupted data flow and should not rely on network routers.

How to stream MPEG-4

Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on the properties of your network. Setting the preferred method(s) is done in the control applet for AMC, which is found in the Windows Control Panel. When this has been set, AMC will test all the selected methods in the specified order, until the first functioning one is found.

AXIS 213 - Video and Audio Streams 15

RTP+RTSP

This method (actually RTP over UDP and RTSP over TCP) should be your first consideration for live video, especially when it is important to always have an up-to-date video stream, even if some images do get dropped. This can be configured as multicast or unicast.

Multicasting provides the most efficient usage of bandwidth, especially when there are large numbers of clients viewing simultaneously. Note however, that a multicast broadcast cannot pass a network router unless the router is configured to allow this. It is thus not possible to multicast over e.g. the Internet.

Unicasting should be used for video-on-demand broadcasting, so that there is no video traffic on the network until a client connects and requests the stream. However, as more and more unicast clients connect, the traffic on the network will increase and may cause congestion. Although there is a maximum of 20 unicast viewers, note that all multicast users combined count as 1 unicast viewer.

RTP/RTSP

This unicast method is RTP tunneled over RTSP. This can be used to exploit the fact that it is relatively simple to configure firewalls to allow RTSP traffic.

RTP/RTSP/HTTP or RTP/RTSP/HTTPS

These two methods can also be used to traverse firewalls. Firewalls are commonly configured to allow the HTTP protocol, thus allowing RTP to be tunneled.

AXIS Media Control

The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) and audio from the AXIS 213 is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows. This ActiveX component is automatically installed on first use, after which it can be configured by opening the AMC Control Panel applet from the Windows Control Panel. Alternatively, right-click the video image in Internet Explorer.

Video & Image settings

The following descriptions offer examples of the available features in the AXIS 213. For details of each setting, please refer to the online help files which are available from each page. Click to access the help files.

To optimize the video images to your requirements, modify the following settings under Image Appearance:

• Resolution (including Aspect ratio correction and 4CIF de-interlacing)

•	Compression	•	Color Setting
•	Rotate Image	•	Brightness

Note: All configuration of images and overlays will affect the performance of the AXIS 213, depending on the usage and the available bandwidth. Please keep in mind the following when changing the image settings:

•Lower compression improves image quality, but generates larger files

•Color uses more bandwidth than Black & White

•Rotating the image 90 or 270 degrees will lower the maximum frame rate

•When using MPEG-4 as the video format, the compression setting will define the minimum compression level. The compression level will temporarily increase as and when required, i.e. when the bit rate approaches the maximum value as defined in the current profile@level combination.

You may need to press the Stop and Play buttons on the Live View page before the settings take effect.

Overlay Settings

Include an image and date and time with your own text which is placed on one line at the top or bottom of the video image.

See Overlay Image Settings, on page 20 for instructions on how to upload an overlay image to the AXIS 213.

Video Stream

Define the maximum video stream time per session in seconds, minutes or hours. When the set time has expired, a new stream can be started by refreshing the page in the browser.

Define the maximum frame rate (fps - frames per second) allowed for each viewer, to avoid bandwidth problems on the network.
