Page 69 Views Using the notation of container, loop, and ﬁeld nodes, the Section View represents the Multiple String Structure in the same way as any other data structure. For example: an Extended Text Table (ETT) carries its extended_text_message in a Multiple String Structure. The default view of a section of an ETT in the Section View looks like this: Section View displays a node for the extended_text_message (with as much as possible of the ﬁrst segment) from the ﬁrst string.
Page 70 Views The contents of each segment loop deﬁne what compression and character set are used, followed by the actual text. The text is held in the compressed_string ﬁeld. Expert and Standard The Multiplexer has two modes of operation for conformance checking when editing table contents.
Page 71 Views An adjacent check mark indicates the mode selected. The mode is also indicated on the Status Bar. In the Section View a padlock symbol is displayed adjacent to all of the ﬁelds that cannot be edited in the current mode. For example, the following screens show the same tables in Standard and Expert mode.

Page 236: Adding Jitter To Pcrs
Reference Adding Jitter to PCRs The MPEG Player provides the capability to add jitter to PCRs (Program Clock References). Adding jitter to PCRs allows you to simulate transmission delay variations and to test the robustness of decoders under various conditions. The jitter function adds jitter to the program_clock_reference_base value and the program_clock_reference_extension value in the adaptation ﬁeld of transport stream packets.
Page 237 Reference 3. After you have set the parameters, press the Apply button to enable the jitter function. Note that the PCR icon in the hierarchy display changes. To disable the jitter function, open the PCR Inaccuracy dialog box and select the Undo button.

Page 239: Using The Continuous Recording Feature
Reference Using the Continuous Recording Feature The Continuous Recording feature allows you to record multiple stream ﬁles continuously on the hard disk. Continuous Recording has the following features: Record multiple stream ﬁles continuously on the hard disk Variable ﬁle size operation The time stamp information of the ﬁrst trigger event in a ﬁle is recorded as the updated date property of the ﬁle Can be used in disk recording mode...
Page 240: Performing Continuous Recording
Reference If a trigger event occurs while the pretrigger area is ﬁlled with data, the pretrigger area becomes smaller than the speciﬁed size. However, the posttrigger area keeps the speciﬁed size. In this case, the size of the File A is smaller than the speciﬁed size. If the second trigger event occurs while the posttrigger area is ﬁlled with data, the second trigger event is ignored.
Page 241 Reference 4. In the dialog box, select the Continuous Recording check box. 5. To the right of the check box, set the number of ﬁles to be continuously recorded. After the speciﬁed number of ﬁles are created, stream capture stops automatically.
Page 242: Remote Commands
Reference After the stream capture stops, recording of the captured streams starts. The ﬁle counter value decreases every time recording of each ﬁle is complete. The recording starts from the last captured ﬁle. If you press the STOP button while the captured streams are recording, the recording process terminates to the ﬁle currently being recorded.

Page 268: Script File Editing And Encryption
Script File Editing and Encryption Script File Editing and Encryption Because script ﬁles are saved as ASCII ﬁles, editing follows normal text editing customs. However, ScriptPad does provide extra features to enhance and verify the process. Keyword Color-Coding When the Auto Syntax Highlights option in the View menu is enabled, keywords are automatically color-coded as they are typed.
Page 269 Script File Editing and Encryption is associated with the .scp and .scx sufﬁxes used for unencrypted and encrypted scripts respectively during the installation process. The script encryption process employs a robust, 128 bit symmetric-key algorithm based on the Feistel block cipher, which is similar to that used in the dongle encryption scheme.
