PDR Digital Recorder - Firmware Revision

PDR v2.00 Release Notes
April 20, 2018

iXML Header Support
Recordings now contain industry standard iXML chunks in the file headers, with the most commonly used fields filled in.

Filesystem Protection
Since computers sometimes write administrative files when a card is installed for recording retrieval, provisions have been made for the PDR to better protect its filesystem state.

Improved Menu Structure
The menu has been reorganized, with some items moved to submenus. The new submenus are named "Timecode...", "SD Card..." and "Settings...".

Bug Fix

The PDR will no longer regard a deleted SD card volume label as valid.
New Functionality

Timecode can now be copied from the internal real time clock, for projects where there is no official timecode reference, but it desirable to embed the time of day as timecode.

Scene and take numbers can now be manually entered, and are embedded in the filenames and iXML headers of recordings. Take number automatically increments each time the record button is pressed.

File browsing and playback can now be organized by file or by scene and take. (When browsing by scene and take, recordings that span multiple files are listed singly and played as one long recording.) Also, the PDR now understands SMWB recordings and can list their format, length, timecode information, etc. The PDR cannot play SMWB recordings because of the sample rate mismatch.

The progress bargraph above the timecode display on the main page now shows the relative amount of space used on the media, appearing fully extended when the card is full.

For greater convenience, recording segment size has been increased from approx. 200 MB to 4 GB. On the largest SD card size supported (32 GB), the maximum number of segments a single recording can have is 8.

The two original file naming templates ("Clock Time" and "Sequence") have been enhanced. (This was made possible by the larger segment size and smaller number of possible segments.) A scene and take based file naming template ("Scene&Take") was also added as a third option.

• Clock Time: DDHHMMA.WAV: DD is the day of the month, HH is hours, MM is minutes, A is the overwrite-prevention character, incrementing to 'B', 'C', etc. as needed to avoid a naming
conflict. A final character serves as the segment identifier, being absent in the first segment, '2' in the second segment, '3' in the third and so on.

• Sequence: NNNNA.WAV: NNNN is the sequence number; the rest is just like Clock, above.

• Scene & Take: S01T001.WAV: The initial 'S' is meant to suggest "Scene" but also serves as the overwrite-prevention character, decrementing to 'R', 'Q', etc. as needed to avoid a naming conflict. The "01" after the S is the scene number. 'T' means take, and the "001" is the take number. An eighth character is used only for the second and subsequent (4 GB) segments for very large recordings. (First segment has no eighth character, second and subsequent, if they exist, use 'A', 'B', etc.)
