7 Logging int o the w eb inter face The Codian IP VCR web interface is used for administerin g the IP VCR device, managing recordings, users, and pre- defined endpoints. You can also perform many recording-rela ted tasks u sing the web interface that you cannot otherwise do.
8 W atching a r ecor ding from the IP VCR The IP VCR offers a variety of ways to watch stored recordings. These incl ude watching recordings using an H.323 endpoint and watching recordings by web streaming. Watching recordings can be an interactive exp erience.
9 Using a video endpoint t o wa tch r ec ordings You may watch recordings sto red on the IP VCR using an H.323 or SIP video endpoint. There are a number of ways to connect to the IP VCR; refer to the .
10 Entering a PIN If you connect to a protected recording, you will be presented with the PI N entr y screen, and will hear audio prompts playing. Use your endpoint's numeric keypad to en ter the PIN, followe d by #. (Note that some endpoints require you to activate the keypad before dialing, for example by pressing the # key.
11 To skip quickly backwards though a recording (fast rewind): 1. Change the camera control to “far”. 2. Use the left control to enga ge rewind mode. The video will ra pidly rewind, skippin g several seconds backwards at a time, and the playback time will be shown in the corner of the screen.
12 Usi ng an auto atten dan t Your system administrator may have set up an auto attendant fo r you to use to view stored recordings. An auto attendant presents you with a menu from which you can choose a recording to watch.
13 To exit DTMF navigation mode: • press the pound (hash) key twice as follows: ## The message "DTMF menu navigation disabled" appears brie fly at the bottom of the auto attendan t display. When in DTMF navigation mode, you will not be able to use the number keys to enter the numeric ID of a recording.
14 Using s treaming t o vie w rec or dings The Codian IP VCR supports streaming, which involves sending recorded media (audio and video) to a remote computer, allowing the user to watch an d listen to the recording. To view a recording using streaming: 1.
15 Using t he IP VCR to mak e a r ec ording The IP VCR allows you to crea te recordings in a number of different wa ys. These include recording conferences on the MCU, recording single video endpoints non -interactively and via the recording c onsole, and transparent recording of point-to-point calls with another endpoint.
16 A utoma tically rec or ding a co nfer enc e on a C odian MCU There are a number of different ways in which you can config ure your IP VCR and MCU to re cord conferences that take place on the MCU.
17 Note that if you are intending to use this m ethod frequently with the same folder, it will be quicker to configure the recording ID as an endpoint on the MCU. The procedure is the same as when you configure an H.323 endpoint on the MCU. For more information, on the MCU, go to Endpoints > Add H.
18 Non-inte ractive r ecor ding of an endpoint Depending on the configuration of the IP VCR, you may be able to make record ings non-interactively. That is, once connected to the IP VCR, recording takes place automatically, and with no feedback to the user.
19 6. Press Call endpoint or Call sel ected endpoint . 7. Answer the call on the video endpoint. Recording will start. Controlling the recording The nature of non-interacti ve recording is that the user has little or no control over recording. When you have finished recording, simply hang up the call to end and store the recording.
20 Using the r ec ording c onsole The recording console allows you to make recordings intera ctiv ely. That is, it allows you to monitor the recording while it is in progress, to check that the view is a s you require.
21 Status A status indication is displayed in the bottom left -hand corner of the recording console. It shows the current sta te of recording. When you first en ter the recording console, the status indication will show paused .
22 Recor ding poin t-to-point calls The IP VCR is able to transparently record po int-to-point calls. A point-to-point call is one where just two endpoints a re involved - the traditional type of call.
23 Calling out fr om the IP VCR As well as using your video endpoint to call into the IP VCR in order to make and wa tch recordings, you may also perform both of these functions using the IP V CR to call out to your endpoint.
24 Understanding the playback and recording para meters pages Whether calling out to play ba ck or to record, you must specify which endpoint you wish to call.
25 strongly favor a resolution of at least 25 frames per second. • Favor sharpness : the IP VCR will use the highest resolution that is appropriate for what is being v iewed. • Balanced : the IP VCR will select se ttings that balance resolution and frame rate (where the frame rate will no t be less than 12 frames per second).
26 H.239 (c onte nt channel video) support The H.239 protocol allows the Codian IP VCR to support an additional video stream to or from each connected H.323 endpoint. Thus, there are potentially 3 me dia stream s between each H.323 endpoint and the IP VCR: audio, main vid eo and H.
27 Creating customized MPEG and Windows Media Video format files The MPEG and WM Converter Tool is a tool that converts .codian files to MPEG-1 or Windows Media Video (.

50 imply potential network problems. Media information If the time stamps or marker bits (or both) are detected to be unreliable in the incoming video stream, information will be displayed here. This field is not displayed when there is no problem with the time stamps and marker bits.
51 For example, if all participants in the conference were watching a single pa rt icipant a t full scree n, no other participants' video streams would be needed at all. So the IP VCR would request that those streams were sent at a low bit ra te in order to avoid needless use of network bandwidth.
52 VCR to this endpoint. Frame rate The frame rate of the video stream currently being sent to the endpoint. Temporal/spatial A number that represents the tradeoff between video quality and frame rate. A smaller number implies that the IP VCR prioritizes sending quality video at the expense of a lower frame rate.
53 Packet loss reported A count of the reported packet loss on the control channel. Sender reports A count of the number of "sender report" type RTCP packets sent by the IP VCR. These are typically sent by any device that is sending RTP media.
54 V ie wing a c onnec ted endpoin t's diagnostics You may view diagnostics for an endpoint's connection to the IP VCR while making and watching recordings. The diagnostics are not available fo r streaming playback connections . To view the diagno stics: 1.

72 C onfiguring network settings To configure the network settings on the IP VCR and check the network status, go to Network > Port A or Network > Port B . The IP VCR has two Ethernet interfaces, Port A and Port B . The configuration pages for the two interfaces look and behave similarly, and so are described together.
73 Secondary name server (DNS) Identifies an optional second name server. Domain name (DNS suffix) Specifies an optional suffix to add when performing DNS lookups. This can allow you to use non-fully qualified host names when referring to a device by host name instead of IP address.
74 Duplex Identifies the connection duplex mode: • Full duplex Both devices can send data to each other at the same time • Half duplex Only one device can send to the other a t a time The duplex setting must match that of the d evice to which this port is connected.
75 C onfiguring IP rout es settings If the Video Firewall feature is enabled (see Upgrading the firmware ), you will need to set u p one or more routing settings to control how IP traffic flows in and out of the IP VCR.
76 Adding a new IP route To add a new route, first enter the deta ils using the table below for reference. When you are satisfied wi th the details entered, click Add IP route to make the addition. If the route already exists , or aliases (overlaps) an existing route, you will be prompted to correct the problem an d try again.
77 If a manually configured route specifies Port B (for example) and that port is disabled, packets matching that route will not be automatically routed via Port A, but d iscarde d. You should take care to avoid this situation. Current IP status This table shows the current default gateway and name server( s) for Ethernet Ports A and B.
78 C onfiguring IP ser vic es To configure IP services, go to Network > Services . Use this page to control the type of serv ices that may be accessed via Ethernet Ports A and B.
79 conference participants who are using H.323. If a port is disabled, this option will be unavailable. Incoming SIP (TCP) Allows/rejects incoming calls to the IP VCR using SIP over TCP. Disabling this option will not prevent outgoing calls to SIP devices being made by the IP VCR.
80 SNMP on Port B. Note that by d efault SNMP Traps are sent to port UDP port 162 (on the destination network management station); this is configurable. For more information, refer to Configuring SNMP settings . H.323 gatekeeper Defines the ports for the H.

82 Trap receiver addresses 1 to 4 Enter the IP address or hostname for up to fo ur devices that will rec eive both the general and the authentication failure traps . The traps that are sent by the IP VCR are all SNMP v1 traps. You can configure trap receivers or you can view the MIB using a MIB browser.
83 C onfiguring QoS settings To configure Quality of Service (QoS) on the IP VCR for audio and video , go to Network > QoS . QoS is a term that refers to a network's abili ty to customiz e the treatment of specific cla sses of data. For example, QoS can be used to prioritize audio transmissions and video transmissions over HTTP traffic.
84 • Bits 0-2 set IP precedence (the priority of the packet). • Bit 3 sets delay: 0 = normal delay, 1 = low d elay. • Bit 4 sets throughput: 0 = normal throughput, 1 = high throughput. • Bit 5 sets reliability: 0 = normal reliability, 1 = high reliabili ty.
85 Displa ying and resetting sy st em time The system date and time for the IP VCR can be set manually or using the Network Tim e Protocol (NTP). To configure Time settings, go to Settings > Time . System time The current system date and time is displayed.
86 C onfiguring encr yption settings You can configure the IP VCR to record encrypted conferences on an MCU and encrypted calls from H.323 endpoints, and to encrypt the connection when playing back a recording to an H.
87 C onfiguring global c onnec tion settings You can modify the global connection settin gs for the IP VCR choosing by Settings > Connections . However, many of these values can be overwritten by o ther IP VCR or endpoint settings.
88 to restrict trans mitted video resolutions for all endpoints. Default bandwidth from IP VCR Identifies the network capa city (measured in bits per second) used by the me dia channels established by the IP VCR to a single parti cipant.
89 the endpoint. The IP VCR chooses an audio codec from those available, and sends audio data to the endpoint in that format. Audio codecs to IP VCR Which audio codecs the IP VCR advertises to remote endpoints, restrict ing the endpoints' choice of channels available for sending audio data to the IP VCR.
90 best with these resolu tions. Video format The video format used and transmitted by the IP VCR. • NTSC The IP VCR will favor transmitting video at 30 frames per second, at SIF-like resolutions. • PAL The IP VCR will favor transmitting video at 25 frames per second, at CIF-like resolutions.
91 Use recording or folder name as caller / called ID When selected, the recordin g or folder name is used for the ID instead of the default device name.
92 C onfiguring gat ek eeper settings To configure gatekeep er settings, go to Settings > Gatekeeper . You can configure the IP VCR to use a gatekeeper, which can ma ke it easier for end-users to watch and make recordings using directory numbers rather than requiring them to know the IP address or ho st name of the IP VCR.
93 Gatekeeper registration type Controls how the IP VCR identifies itself wh en registering with its configured gatekeeper. Codian recommends that you use the Terminal / gateway option unless you are using a service prefix or point-to-point prefix (in this case, use Gateway ).
94 the registration prefix is "99", then the recording will be registered with the gatekeeper with a gateke eper ID of "992222" • register as a service prefix : the numbers are used as a service prefix for the IP VCR on the gatekeep er.
95 Deregister recording prefixes when all recording ports are in use When selected, configured recording prefixes (both the Prefix for IP VCR re gistrations if used as a service prefix and the Point to point call incoming prefi x set for any folders) will be deregistered wh en all recording ports are in use on the IP VCR.
96 VCR registrations for all registrations from the IP VCR. table above. Play back prefix Displays the prefix registe red with the gatekeeper for playing back stored record ings.
97 IP VCR gat ek eeper registr ation beha vior This is a summary of the gate keeper regi stration behavior on the IP VCR. It also explains how you can use a gatekeeper for load balancing.
98 1. If the Prefix for IP VCR registrati ons has been configured and the called numbe r starts with that prefix, then the IP VCR tries to match th e rest of the called ID number (i.e. the part after the prefix) to a recording's Numeric ID or to one of the folder IDs.
99 Load balancing You can use prefixes to balance the load between a number of IP VCRs by registering them with th e same prefixes and selecting the "deregi ster" options: • the Play back .
100 C onfiguring SIP settings SIP calls will select the audio and video codecs to use from those allowed on the Settings > Connections page, unless the call is with a endpoint configured with a Custom codec (refer to Configuring SIP endpoints for more information).
101 address through a registrar or not. Outgoing transport Whether the outgoing transport will be TCP or UDP. If your SIP devices use TC P, select TCP as the outgoing transport. If your SIP devices use UDP, select UDP as the outgoin g tran sport. The IP VCR accepts connections on both TCP and UDP.
102 C onfiguring H.239 settings These settings affect the behavior of the IP VCR with regard to H.239. H.239 is the protocol that allows for an additional video channel (known as the content channel) .
