Possible causes for a DEC error
Possible cause 1: An error notification was issued by the decoder, because there was an error in the stream.
How to diagnose: Play back the file on the PC to check if an error is generated.
Possible cause 2: Data reading failed while the data were being transmitted to the decoder.
How to diagnose: Check the ATA error log on the Debug screen.
* See "How to check the ATA error log," above.
A "CH" error does not occur during AAC playback.
Possible causes for a QNT error
Possible cause 1: The encoding method is not 16-bit quantization.
How to diagnose: Check the number of quantization bits, using a PC analysis tool.
Possible cause 2: After data reading failed, an erroneous number of quantization bits was obtained.
How to diagnose: Check the ATA error log on the Debug screen.
* See "How to check the ATA error log," above.
Possible causes for a BPS error
Possible cause 1: The average bit rate exceeded 480 Kbps.
How to diagnose: Check the average bit rate, using a PC analysis tool.
Possible cause 2: After data reading failed, an erroneous average bit rate was obtained.
How to diagnose: Check the ATA error log on the Debug screen.
* See "How to check the ATA error log," above.
Possible causes for an FS error
Possible cause 1: The sampling frequency was less than 8 KHz or greater than 96 KHz.
How to diagnose: Check the sampling frequency, using a PC analysis tool.
Possible cause 2: After data reading failed, an erroneous sampling frequency was obtained.
How to diagnose: Check the ATA error log on the Debug screen.
* See "How to check the ATA error log," above.
Possible causes for a BOX error
Possible cause 1: An impossible box size was obtained during box analysis.
How to diagnose: Check the box size, using a PC analysis tool.
Possible cause 2: Data necessary for playback could not be obtained.
How to diagnose: Analyze the file, using a PC analysis tool, and check that SAMPLE DESCRIPTION BOX, TIME TO SAMPLE
BOX, SAMPLE SIZE BOX (SAMPLE SIZE 2 BOX), SAMPLE TO CHUNK BOX, CHUNK OFFSET BOX
(64BIT CHUNK OFFSET BOX) exist.
Possible cause 3: SAMPLE DESCRIPTION BOX, which signifies that audio streams are contained, did not exist.
How to diagnose: Check the binary data of the file with which this error was generated and confirm that the 20th byte does not
indicate "mp4a." (A DRM file may also have this error.)
Possible cause 4: "AudioSpecificConfig" was not described in "SAMPLE DESCRIPTION BOX," which should show that an
audio stream is contained.
How to diagnose: Check AudioSpecificConfig, using a PC analysis tool.
Possible cause 5: Data reading failed during file analysis.
How to diagnose: Check the ATA error log on the Debug screen.
* See "How to check the ATA error log," above.
Possible causes for a PRF error
Possible cause 1: Audio streams were not contained in "AAC LC" and "High Efficiency AAC Profile."
How to diagnose: Check the type of audio stream in AudioObjectType of AudioSpecificConfig, using a PC analysis tool.
Possible cause 2: After data reading failed, erroneous AudioObjectType data were obtained.
How to diagnose: Check the ATA error log on the Debug screen.
* See "How to check the ATA error log," above.
Possible causes for an MEM error
Possible cause 1: The shared memory region for the system was fragmented, and the memory region of 4,096 bytes that was
necessary for file analysis could not be ensured.
How to diagnose: After setting the unit to Standby mode, turn the unit back on and check if an MEM error is generated.
If it is, the system memory may be defective.
