A.3 Format for test sequence distribution
3GPP46.010Full rate speechRelease 17TranscodingTS
A.3.1 Type of files provided
Three types of files are provided:
‑ Files for input of the encoder: *.INP;
‑ Files for input of decoder or comparison with encoder output: *.COD;
‑ Files for comparison with the decoder output: *.OUT;
Five disks are provided containing all the digital test sequences. Disk1.zip contains all test sequences that are required for a codec implementation without codec homing while disk2.zip and disk3.zip contain the test sequences required for a codec implementation with codec homing. Disk4.zip and disk5.zip contain the 8 bit test sequences with A-law and ‑law compression, respectively.
Disk1.zip contains the SEQ01.INP, SEQ01.COD, SEQ01.OUT, SEQ02.INP, SEQ02.COD, SEQ02.OUT, SEQ03.INP, SEQ03.COD, SEQ03.OUT, SEQ04.INP, SEQ04.COD, SEQ04.OUT, SEQ05.COD, SEQ05.OUT files. Disk2.zip contains the SEQ01H.INP, SEQ01H.COD, SEQ01H.OUT, SEQ02H.INP, SEQ02H.COD, SEQ02H.OUT files.
Disk3.zip contains the SEQ03H.INP, SEQ03H.COD, SEQ03H.OUT, SEQ04H.INP, SEQ04H.COD, SEQ04H.OUT, SEQ05H.COD, SEQ05H.OUT, SEQ06H.INP, SEQ06H.COD, HOMING01.COD, HOMING01.OUT, BITSYNC.INP, SEQSYNC.INP and SYNC000…159.COD files.
Disk4.zip contains the A-law compressed 8 bit test sequences with and without homing. All the files of disk1- 3.zip except for BITSYNC.INP, which is not necessary for TRAU testing, are on disk4.zip. The extension _A is added to the filenames in order to indicate A-law. The files HOMING01, SEQSYC and SYNC000… are renamed to HOM01_A, SEQSYN_A and SYN000_A, respectively.
Disk5.zip contains the -law compressed 8 bit test sequences with and without homing similar to disk4.zip. The _u in the filenames stands for -law.
Table A.3.1a/b gives the contents of the five disks and also the size in bytes and the number of frames for each test sequence file.
A.3.2 File format description
All the files with the linear 13 bit test sequences are written in binary using 16 bit words. This means that input samples (sop[k], on files: *.INP), output samples (srop[k], on files: *.OUT) and coded parameters (on files: *.COD) use 2 bytes each. Hence the sizes of the files are directly related to the number of processed frames.
For files with linear 13 bit sequences and .INP or .OUT extension type:
Size (in bytes) = No of frames * 160 * 2;
All files _x.INP and _x.OUT with the compressed 8 bit test sequences are written in binary using 1 byte per sample.
For files with compressed 8 bit sequences and _x.INP or _x.OUT type:
Size (in bytes) = No of frames * 160 * ;
For all files with .COD extension type:
Size (in bytes) = No of frames * 76 * 2;
Table A.3.1 shows the size of all the 13 bit linear files written in direct binary format. The size of the files containing the optional 8 bit test sequences with type _x.INP and _x.OUT is half the size shown in the table (disk4.zip and disk5.zip).
