Configuration In This Chapter This chapter explains how to use the user interface to set up the CDP-100. This discussion is based on the use of DashBoard through a network connection. The order of sections in this chapter follows the workflow required to setup the CDP-100 for operation. It is recommended that you proceed through the following sections in order to achieve the best possible understanding of the product.
General Settings This section provides a summary of the initial tasks you may wish to perform before configuring your card for data collection. To configure the general settings 1. Select the Settings tab. 2. Type a unique name for your card in the Card ID field. This is especially useful if you have more than one CDP-100 in a frame. If this field is blank, the name is “CDP-100”. 3. Specify the overlay of the CDP errors on the two outputs of the card.
Capturing Data The Capture Data tab provides an easy method to know the exact bits and bytes of the CDPs when an error occurs. This data is suitable for detailed analysis by the CDP File Analyzer program which runs on a PC. To capture and save data to a file 1. Select the Capture Data tab. Capture Data Tab 2. Select a data collection method from the Run Mode area. The CDP-100 internally stores 1800 packets.
CDP File Analyzer This program is supplied on an install CDROM. Once installed on your PC, it will prompt for a license key which applies to the PC on which it is installed. Contact Ross Technical Support and provide the information given by the program and Ross Video will provide you with this key.

Caption Display The Caption Display tab includes the Caption Display 1 and Caption Display 2 menu items that control which caption channel text is displayed on the overlay. The display of captions will reduce the number of unique error types that can be displayed simultaneously on the overlay screen but has no other effect on error logging. Caption Display Tab CDP-100 User Manual (Iss.
GPIO Assignments The GPIO Assignments tab enables you to assign a GPIO to be triggered when an individual CDP error condition or when any CDP error occurs. When used in conjunction with the error levels to mask off unwanted errors, it is possible to build a subset of errors that will trigger a GPIO. To assign a GPIO to an individual CDP error condition 1. Select the GPIO Assignments tab. GPIO Assignments Tab 2. From the GPIO 1 menu, assign the type of error condition to trigger the GPIO. 3.
Selecting a Time Source The CDP-100 requires a time source to time stamp errors in the log. The Time tab is used to select this time source. Selecting a Time Source Time can be set accurately and automatically by using LTC time or Network Time. LTC requires connection of linear timecode source to the card and network time requires an NTP server accessible on the LAN that is connected to the DFR-8300 series frame. To use an NTP Server as the time source 1. Select the Time tab. Time Tab 2.
To manually specify the date and time 1. From the Time Source area, select Manual. Use this option when neither Network Time or an LTC source are available. 2. Using the options in the Manual area, specify the date and time. 3. Click Accept to apply your changes. Using an NTP Server as the Time Source In order to use network time, you also need to ensure that the MFC-8300 Series Network Controller card in the openGear frame has been configured to acquire time from an NTP server.
Errors Levels The Error Levels tab enables you to select which type of CDP-100 error to mask. To select which errors to mask 1. Select the Error Logs tab. Error Logs Tab 2. For each type of error there are the following options: CDP-100 User Manual (Iss. 03) • Error — Error is displayed, registered in the error logs and causes the CDP-100 to stop capturing in “Stop on Error” and “Stop Centered on Error” modes.
Error Logs The Error Logs tab lists each error type and indicates the time the error last occurred. Possible log messages are “None”, a start time only indicating the error is currently taking place, or a start time and an end time indicating the error occurred sometime in the past. The complete log history can be downloaded to the DashBoard client computer. To download the error log 1. Select the Error Logs tab. 2. Click Save. Note that clicking Reset clears the log history.

Understanding CDP Errors In This Chapter The CDP-100 detects most coding errors in the CDP. This chapter attempts to describe each error, what problems it might cause and how severe it may be. The following topics are discussed: • CDP Error Overview CDP-100 User Manual (Iss.
CDP Error Overview It should be noted that each device acts differently when presented with each error type. It is therefore impossible to say with certainty whether an error will cause a loss of captioning. It is best practice to ensure that no errors are present in the CDP to give the best chance that all captioning will pass through to the TV sets correctly. The user should also be aware that not all monitoring equipment will show all problems with the captioning stream.
there may be a loss of caption text when the error occurs but normal captioning will return after the error. CDP Header, Frame rate does not match current video Explanation The CDP header contains a frame rate for which the CDP was constructed. This is important because the amount of data carried in the caption portion of the CDP varies with frame rate. This error is signaled when the frame rate of the actual video does not match the frame rate specified in the CDP header.
CDP Header Reserved bits are not set correctly Explanation The CDP header has bits which convey no information at this time but are reserved for future standardization. The SMPTE 334-2 standard defines how these bits should be set. This error is generated any time a reserved header bit is not set according to the standard. Severity The severity of this error varies greatly depending on equipment. Some equipment completely ignores reserved bits and does not care how they are set.
CDP Caption, Reserve bits are not set correctly Explanation The CDP caption information area has bits which convey no information at this time but are reserved for future standardization. The SMPTE 334-2 standard defines how these bits should be set. This error is generated any time a reserved caption information bit is not set according to the standard. Severity Most devices do not check reserved bits, so normally this error does not cause a problem.
CDP Service, Change flag does not match header Explanation The CDP service information may be too large to place in a single CDP so may be broken into pieces and spread over more than one CDP. To allow for decoding of the service information there are flags to indicate the start and end of the service information and when the service information has changed. These flags reside in both the header of the CDP and in the service information section.
CDP Caption, 708 caption block sequencing error Explanation The CEA 708 native captioning stream(s) are carried in triplets in the same fashion as the embedded CEA 608 captions streams. The first byte of the triplet identifies the type of data carried in the triplet and the other two bytes are the data. For 708 data, the first byte will define it as 708 data and whether this triplet starts a set of captioning service blocks.
CDP Caption, 608 Field 2 Data Missing Explanation Field 2 608 data carries second language captioning and extended data services (XDS) such as VChip. When these services are not present, some equipment does not code the 608 field 2 triplet into the captioning data section of the CDP. Most equipment encodes a field 2 null triplet. Severity This is not a severe problem and will not usually cause a loss of captioning.
