[Mp4-tech] [Audio] ADTS

[Saptarshi Ghosh]

Hi all,
Could anyone please answer the following two
questions:
Question 1.
Is it necessary to overlap/add the raw data blocks in
a SINGLE ADTS frame with the raw data blocks in any
other frame or can the data in a SINGLE frame be
decoded independently ?
Question 2.
For crc checking, CRC16 polynomial 0x1021 is used. In
this respect, please clarify the following parameters
of the crc algorithm used:
1. Initial value of 16-bit register when the algorithm
starts
2. Whether each byte is reflected before it is
processed
3. Whether the final register value is to be reflected
4. Whether any 16-bit number is to be XORed to the
final register value
5. The checksum for the data string "123456789" as
produced by this algorithm.
Thanking you,
S.G.
