MPEG-2 Configuration The following information represents guidelines for product configuration limitations, with regard to specific unit types. When configuring VBrick units, close attention must be paid to the total transport rate of all sources both entering and exiting the unit. In most cases the sum of all entering and exiting MPEG-2 data traffic should be closely monitored and kept to a minimum whenever possible.
Model Dest1, Dest2 Slot #1 Decoder Slot#2 Recorder FTP Active Player / Pump 6200 12,0 12 12 Yes 0 6200 11,0 11 0 No 11 6200 9,0 9 0 Yes 9 6200 11,11 11 11 No 0 6200 10,10 10 0 No 10 4300 17,0 17,0 0 No 0 4300 11,11 11,11 0 No 0 4300 13,0 13,0 13 No 0 4300 11,0 11,0 0 No 11 4300 9,9 9,9 9 No 0 4300 8,8 8,8 0 No 8 5300 17 17 0 No 0 5300 13 13 13 No 0 5300 14 14 0 No 14 Note All values are shown in Mbps.
MPEG-2 Configuration Network DHCP Dynamic Host Configuration Protocol – (Enable, Disable). On Ethernet models, if DHCP is enabled, the VBrick gets its IP Address or Network Timer Server and Subnet Mask from the DHCP server. If the DHCP server supplies the Gateway Address or DNS server address, these parameters will replace the user entered Gateway and DNS Time Server settings.
Gateway IP Address Valid gateway IP Address for communicating across distinct network segments. A valid gateway IP address is essential even though the VBrick will operate without one in some cases. When no gateway is configured, the VBrick may be unable to communicate with off-net IP hosts, for example, a foreign host which is used for configuration management via IWS.
MPEG-2 Configuration Maximum Transmission Unit Size Range 1024–1500 (default = 1500). The MTU is used for all network traffic from the VBrick and defines the largest network packet size that will be transmitted. A higher MTU brings higher bandwidth efficiency and VBrick recommends using the default. However you may wish to reduce MTU size to meet the requirements of some networks with VPN or other security tunnels that cannot tolerate 1500-byte packets.
12 Routing Method This selects which routing method will be used: Changes made to the Routing Method will require a reset of the box. • Static – Allows routes entered in the static routing table to be automatically applied to the internal routing tables, after a powerup. • RIP Version 1 – Configures the VBrick to listen to RIP announcements. Routes are dynamically added per RIP specification. • RIP Version 2 Broadcast – Configures the VBrick to listen to RIP version 2 announcements.
MPEG-2 Configuration Configuration: Network > Management These parameters define information used in the SAPs emitted by the VBrick, which are received by the VBDirectory management tool (see the VBDirectory User Guide) and other VBrick applications such as the ETV Portal Server. Group Name Optional. This parameter defines the Group Name. It is included in the Management SAPs used by VBDirectory. It is used for organizing VBricks into groups to simplify use of VBDirectory. Unit Number Optional.
Configuration: Network > IPv6 In the current implementation of IPv6, MPEG-2 encoded streams can be unicast over IPv6 to an IPv6-enabled version of VBrick StreamPlayer. In this version, you continue to manage and configure the appliance over IPv4. IPv6 Auto Config Enable Enable IPv6. When enabled, the IPv6 parameters for IP Address and Gateway IP Address are automatically set. This is the recommended method. IP Address IPv6 IP address of the VBrick.
MPEG-2 Configuration On/Off Turn Billboard on or off. IR Enable the IR remote control. If enabled you can turn the Billboard on or off using the remote. URL The local or external URL of the Billboard page. Using the Billboard Billboard may be invoked in several ways. Either use the PC browser to communicate with the VBrick Integrated Web Server (see separate section) to apply the billboard and turn it on and off, or press the Billboard key on the optional remote control to toggle it on and off.
Use the Username and Password (default is case sensitive admin, admin) to login to the VBrick. BB01 through BB16 are directories established to receive Billboard content. It is possible to cut and paste new contents to a Billboard location from a file located anyplace on the network or on the computer. To view the contents on the VBrick, change the URL in the Billboard Section of the Integrated Web Server. In this example, the URL for the new file in IWS Configuration: Billboard would read: file://.
MPEG-2 Configuration Creating a Billboard A billboard that fits on one screen (640 x 480 resolution) can be created using the following HTML tags: A DIR H3 IMG PRE AREA DL H4 INPUT SCRIPT B DT H5 LI SELECT BASE EM H6 MAP SMALL BIG FONT HR MENU STRONG BLOCKQUOTE FORM HTML META STYLE BODY TH TITLE NOBR NOFRAMES TABLE BR FRAME FRAMESET CAPTION HEAD TR OL TEXTAREA CENTER H1 U OPTION UL DD H2 I P TD The billboard text generated by the browser is Times Roman.
Configuration: Decoder Configuration: Decoder > Video The VBrick decoder is used to uncompress MPEG streams and display them on a TV or monitor. 18 Decoder Video Format The format can be configured to be NTSC (30fps), PAL (25fps) or PAL-M (30fps). PAL-M is a video format standard used in Brazil.
MPEG-2 Configuration Configure PID MPEG-2 transmits its data in packets of 188 bytes each. At the start of each packet is a packet package identifier (or PID) that identifies the data stream associated with that packet. Because the MPEG-2 data stream might contain multiple video programs, the decoder has to choose a particular video channel to play. The PID selection provides that feature. If the user selects the automatic option, the first video PID identified will be used to select the video channel.
Output Level Hardware-dependent; not shown on all models. Changes the range of values for Left and Right Gain. Normal – 14 dB to -48 dB (+14 to -48 on some decoder models). Alternate – 8 dB to -54 dB (+14 to -48 on some decoder models). Left Gain Used to adjust volume. Default = 0. Right Gain Used to adjust volume. Default = 0. Configure PID MPEG-2 transmits its data in packets of 188 bytes each.
MPEG-2 Configuration Receive Enable Controls whether the decoder receives the video from the network. Receive Address Mode Allows the user to specify how the receive address will be configured: • IP Address – If the address entered in Receive IP Address (see below) is 232/8, the decoder will issue a source-specific multicast join if you enter the IPv4 address of the encoder in the Source IP Address field. • Host Name – This mode is only used for receiving unicast from the encoder.
22 Receive IP Address Use when Receive Address Mode is IP Address. In multicast mode, this parameter defines the IP address of the stream to be decoded and displayed. In unicast mode, this parameter is optional. If left blank, the decoder will accept all data received on the receive IP port. If set, decoder will communicate with any VBrick that has the encoder "unicast poll" option set, and instruct it not to transmit it's stream unless this VBrick has this receive IP Address.
MPEG-2 Configuration SAP Category This string can contain one or more category keywords that will limit the video streams displayed by the Program and Conference Guides. Keywords should be separated by spaces. Note that characters are ASCII and can only be lowercase. The total of all keywords in the string is 36 characters including spaces.
PIP Horizontal Size The Picture-In-Picture horizontal size can be changed to any of the following 4 sizes – full, half, quarter, thumbnail. PIP Vertical Size The Picture-In-Picture vertical size can be changed to any of the following 4 sizes: full, half, quarter, thumbnail. Brightness (0 – 15) The luminance is the information about the varying light intensity of an image, is best described as brightness. Default = 0. Saturation (0 – 15) The saturation is the spectral purity or intensity of a color.
MPEG-2 Configuration Transport Content If the model number ends in -xxx1/-xxx2, the user can choose the transport content to be Video + Audio, Video only or Audio only. If the model number ends in -xxx0, the option is not displayed and video and audio always comprises the transport content. Delay Mode If the model number ends in -xxx1/-xxx2, the delay mode can be set to Low, Medium or High Delay. If the model number ends in –xxx0, the delay mode can be set to Low or High Delay.
Video Format The format can be configured to be NTSC (30fps), PAL (25fps) or PAL-M (30fps). (The PAL-M feature is supported on models ending in xxx1 or higher.) PAL-M is a video format standard used in Brazil. The main difference between PAL and PAL-M is a lower resolution (525 lines versus 625) and a higher frame count (30 frames per second at 60 Hz versus 25 frames per second at 50 Hz). Video Aspect Ratio Aspect ratio is the ratio of the width of the image to the height of the image.
MPEG-2 Configuration Closed Caption Enable Disables or enables closed captioning. It is recommended that Closed Caption be disabled unless required by an application. Default = disabled. Does not apply to models ending in -xxx0. • Disabled – Default. • Video CC Enabled – Reads the embedded video closed captioning text. • Inserted CC Enabled – Inserts the user defined text set in the Closed Caption Text field. Closed Caption Type Sets the Closed Caption Type to either ATSC Compliant or Alternate Format.
Reference Distance For models ending in -xxx1/-xxx2, enables a user to set the difference between consecutive reference frames within a group of pictures (GOP). The values available are 1–3 (default = 2). If the Encoder Transport Delay setting is low or medium, the value must be 1. Does not apply to models ending in -xxx0. If Reference Distance and Intrapicture Distance are both 1, the encoder will produce all I frames.
MPEG-2 Configuration Video GOP Time The hours, minutes and seconds for the GOP time, the creation time of the MPEG video stream. Can be set to one of three selections: • Encoder Time (default) • GMT Time • Local Time Note: Within the GOP header of the video stream is a Time Stamp, in hours, minutes and seconds. If the receiving application uses this time stamp, it is desirable to configure the encoder to insert a real time of day in either local or GMT time.
Audio Input Input can be from an Audio Jack (1/8" mini-phono jack) or from Microphone DIN (AudioMate microphone). The default setting is Audio Jack. Audio Balance -127 to 127. Sets audio balance between left and right channels. Zero is balanced. 127 sends audio to right channel only; -127 to left channel. Audio Input Level Hardware-dependent; not shown on all models. See Audio Gain field for more details. • Normal – 7 to –53 dB and mute. • Alternate – 12 to –48 dB and mute.
MPEG-2 Configuration Audio Channels Model dependent. (If the EEPROM Revision is 2 or higher, changing the Audio Channel setting affects the Sample Frequency. ) • If the model number ends in –xxx0, the parameter can be set to Stereo, Mono and Dual. The default setting is Stereo. • If the model number ends in –xxx1/-xxx2, the settings are dependent on the PLX EEProm revision Number: • If the EEProm Revision is 1, this parameter can be set to Stereo and Mute. The default setting is Stereo.
Destination Address Mode Allows the user to specify how the destination address will be configured: IP Address, Host Name, or IPv6. • IP Address – This is the Destination IP Address of the encoded video. When this is a multicast address, the transmit mode is also set to multicast. Similarly, if this is a unicast address, the transmit mode is also set to unicast. • Host Name – Sets the source for video to be received using Host Name of the source. It can be used only for a unicast source.
MPEG-2 Configuration Packet Payload Size Controls the amount of MPEG data within each UDP packet. The default value is 4136. Since Ethernet networks are limited to a packet size of 1500 bytes, multiple IP packets are required to span one UDP packet. When choosing a packet payload size, special attention must be paid to the network capability and topology. The allowed range is 1316 to 8872 bytes per packet, even numbers only.
Join Own Multicast Some network equipment requires that a multicast source (such as a VBrick encoder) join its own multicast group. This feature is enabled by default and has no adverse affect on equipment that is fully multicast compliant. Configuration: Encoder > Announce (SAP) Contains parameters used to change the SAP (Session Announcement Protocol) advertisements.
MPEG-2 Configuration Announce Common Information Program Name The string providing the name of the stream associated with this SAP. This SAP text shows up in the Program Guide for other VBrick products. Default is \H Program x (where x is 1 or 2, for slot1 or slot2). Note: All of the Common Information fields support replacement characters. The replacement text is only shown in the SAP message at the destination decoder. The fields are replaced by the actual information as explained below.
Category An encoder can have a SAP Category string. This string consists of one or more keywords separated by spaces. Each category keyword represents a tag associated with the Encoder's video stream. Decoders can be configured to display in their Program and Guides only video streams tagged by specific category keywords or those containing no keyword. The string(s), used by the Decoder, is set on the Decoder/Network screen. Note: Characters are ASCII and are case sensitive.
MPEG-2 Configuration Note SAP information appears in the Program Guide field displayed in other VBrick products, such as StreamPlayer and StreamPlayer Plus. Configuration: Pump See VBStar Pump on page 100. Configuration: Recorder See VBStar Record on page 105. Configuration: FTP File Transfer See VBStar FTP File Transfer on page 111. Configuration: Conferencing Conferencing is a feature that allows a user to set up a two-way video conference using the IR Remote Control.
Conference End Display Mode Allows the choice of what is displayed when the conference ends. Display either Picture-in-Picture (with the local encoder view) or a Blank Screen. Local Ringer IR If Enabled, the ringer may be enabled or disabled via the IR remote by the user (operator) of this VBrick. If disabled, the local operator cannot change the state of the ringer. It will remain as set above in "local ringer". Conferencing Name Used to configure the name of the user (operator) of this VBrick.
MPEG-2 Configuration Passthrough State Used to enable/disable Passthrough. Three states are possible: • Disabled – The VBrick will neither initiate nor respond to Passthrough setup requests. • Responder – In this case the VBrick will accept a connection request (up to 64 connection requests) from another VBrick set as an Initiator or from a PC camera control application. • Initiator – In this case it will continuously attempt to automatically initiate a Passthrough connection to the remote destination.
Baud Rate Rate can be set to the following (Default = 9600): 110, 300, 600, 1200, 2400, 3600, 4800, 7200, 9600, 14400, 19200, 28800, 38400, 57600, 115200. Stop Bits Number of stop bits for Passthrough port (1 or 2). Parity None, Even, Odd. RTS Control Force Off, Force On or Automatic. If automatic, the control will be on when Passthrough is active. DTR and RTS are available for COM2 only for those VBrick models whose last digit is 3 or higher.
MPEG-2 Configuration Destination • Remote COM1 using Slot1 Video Endpoint. This means that all serial data originating at the COM1 port being configured is sent to the COM1 port of the VBrick identified as the Slot1 video source (if Slot1 is a decoder) or to the Slot1 video destination VBrick (if Slot1 is an encoder). • Remote COM2 using Slot1 Video Endpoint. Slot1 Destination 1 only. Same as above except Initiator destination is COM2. • Dedicated.
Baud Rate Rate of Passthrough port. Rate can be set to the following (Default = 9600): 110, 300, 600, 1200, 2400, 3600, 4800, 7200, 9600, 14400, 19200, 28800, 38400, 57600, 115200. Stop Bits Number of stop bits for Passthrough port (1 or 2). Parity None, Even, Odd. RTS Control Force Off, Force On or Automatic. If automatic, the control will be on when Passthrough is active. DTR and RTS are not available for COM2. Under no conditions are RTS or DTR controls passed through end-to-end.
MPEG-2 Configuration Network Time Synchronization Enabled or Disabled. If enabled, the System Date Time field is inactive. See Network Time Synchronization on page 11 to set host name or IP address of time server. You must set these parameters before you can enable Network Time Synchronization on this window. System Date Time Set system date and time in mm/dd/yyyy hh:mm format. System Current Operational Mode Indicates the current operational mode of the VBrick. The following modes are supported.
Daylight Savings Time Enabled or Disabled. IR Enable Enable or Disable the IR remote control. This is the master enable and disable for the IR across all functions. Fan Mode This option allows a user to either force the fan always high or to automatically cycle on and off based on measured temperature. Default = Automatic. Note: This option is only available on VBrick models with a main board assembly whose last four digits are 0206 or higher.
MPEG-2 Configuration the VBrick. The two MIB files are VBrick_box2.mib and VBrick_reg.mib. The default installation directory is: Program Files\VBrick\VB6000\Download\ReleaseVxx_xx_xx Traps are SNMP base messages used by SNMP elements to report changes in status or alarm conditions to remote SNMP management entities. Traps are generally used to alert network administrators of potential equipment problems or other noteworthy events.
SNMP Trap Version Select Version number. Trap User Name User assigned trap name. Authentication Password Enter password. Cannot exceed 20 characters. May include any combination of alphanumeric characters but only the following special characters: ~ ! # $ ^ * + & [ ] { } | < > See Table 5 on page 93 for defaults. Authentication Protocol Select protocol: MD5 or SHA to validate the transaction between a given host and client Privacy Password Required. Hides traffic using DES encryption.
MPEG-2 Configuration Number Event Description 22 The 2.5 volts power supply failure has cleared. 23 There is a Real Time Clock battery failure. 24 The unit has been configured to transmit and/or receive video streams beyond its capability. 25 Signifies the overloaded unit is recovered to normal. 26 A component on the main board failed Power On Self Test (POST). 27 The encoder card in Slot1 failed Power On Self Test (POST). 28 The encoder card in Slot1 failed Power On Self Test (POST).
External SNMP Default = Enabled. Disabled will prevent you from using an external MIB browser to view or write parameters. External SNMPv1 and SNMPv2 Access Default = Enabled. You can use both SNMP v1/v2, and v3. For tightest security, set parameter to Disabled and use SNMPv3 only. Remote Support Enable Default = Disabled. Check to enable remote support by VBrick Support Services. Note: Any change to this parameter will reboot the appliance. Remote Support Poll Enable Default = Enabled.
MPEG-2 Configuration benefit of collecting log information from several VBricks simultaneously. When logging externally, specify either the IP address or hostname a server that is configured to receive SNMP traps on port 162 into the Remote Event Log IP Address or Remove Event Log DNS Host Name fields. Log Time Zone Specifies the time zone (Local or GMT) that is used for logged events. Trap Log Local If Enabled, displays trap events in the local log.
Configuration: Video On Demand This screen is used to configure the capability of the VBrick to support VBrick's legacy Video on Demand server (VBVoD). This is not the VoD server used with VBrick's ETV Portal Server. Video On Demand Enables or Disables the Video-on-Demand capability of the VBrick appliance. When enabled, the user will be able to view Video-onDemand SAPs in the Program Guide.
MPEG-2 Configuration Configuration: Script Management Configuration: Script Management > Event Triggering You can create and run scripts to activate certain functions on a VBrick appliance. There are three ways to run scripts on an appliance. (1) You can run scripts for test purposes using the Run Script button in IWS; (2) you can use the IR Remote Control; and (3) you can use an external event trigger (see "Event Triggering" in the VBrick Appliance Getting Started Guide).
Click here to read Login to the VBrick via FTP and manage script files. Requires a valid or write script files user name and password. Event Enable Allows the user to Enable/Disable Event Triggering for each input event. Event Stable Time Allows the user to enter the amount of time in milliseconds that each input event has to be stable at the active level before the script will be executed. Figure 3. Script Management – Part 2 Event Count Displays the number of times each input event has occurred.
MPEG-2 Configuration Sample Script vbrickSlot2EncoderNetworkTransmitEnable = 2 // set enable slot 2 encoder transmit vbrickSlot2EncoderNetworkApplySet = 2 // apply above encoder network set * // end of a group vbrickHDRecorderControlMode = 1 // set recorder to user controlled mode vbrickHDRecorderControlIrEnable = 1 // disable recorder ir control vbrickHDRecorderControlName = event1record.mpg // set recorder file name vbrickHDRecorderControlDuration.
The VBrick reads the URL field (e.g. www.myserver.com/config.xml ) via HTTP protocol and executes the script depending on the EXECUTE tag. If a VBEXECUTEFORCE tag is present in the .xml file (see example below), the script runs every time at the poll interval even if it has not changed. If a VBEXECUTEIFDIF tag is present the script runs only if it is different from the last executed file. One of these tags is required.

Diagnostics: Network Tests > Data Test Data tests are used primarily to test the integrity of a network connection between two VBricks. A loopback test takes all data received at the video IP port and retransmits the data to the configured transmit IP destination. A loopback test may be used to observe the quality of the video data after looping back at the destination. A loopback test is available only for encoder-decoder models and is bi-directional.
Diagnostics validates the data pattern. In this mode the following steps are recommended. No timed or continuous option is available for this test mode. • • • • Turn on transmit Turn on receive Turn off receive Turn off transmit Diagnostics: Device Test This screen shows the results of the Power-On Self Test, which is automatically run when the VBrick is reset or powered on.
Diagnostics: Decoder Color Bars The Decoder Color Bar test is a simple test that generates color bars at the video decoder and outputs them in the place of video. It can be used to test basic decoder operation and the monitor. 84 © 2009 VBrick Systems, Inc.

VBStar VBStar Record Using Mixed Models MPEG-2 encoders behave differently when mixed models are present in the same enclosure. For example when there is a WM encoder in Slot1 and an MPEG-2 encoder in Slot2, the MPEG-2 recorder becomes an archiver and not a recorder. This section explains in detail how the MPEG-2 encoder works when functioning as a recorder.
test1.mpg; if test1.mpg, test2.mpg and test3.mpg exist, and the Recorder File Name is still set at test.mpg, the new recording will start at test4.mpg. If the Recorder File Name is set at to particular index number, such as test2.mpg, the first file to be recorded will be test2.mpg and the batch recording will increment from that number. Note The maximum batch file size is 4 GB.
