The following errata report has been submitted for RFC7574,
"Peer-to-Peer Streaming Peer Protocol (PPSPP)".

--------------------------------------
Type: Technical
Reported by: Sung Hei Kim, Chang Kyu Lee <shkim@etri.re.kr>

Section: 1.3

Original Text
-------------
swarm ID
Unique identifier for a swarm of peers, in PPSPP a sequence of
bytes. For video on demand with content integrity protection
enabled, the identifier is the so-called root hash of a Merkle
hash tree over the content. For live streaming, the swarm ID is
a public key.

Corrected Text
--------------
swarm ID
Unique identifier for a swarm of peers, in PPSPP a sequence of
bytes. For video on demand, the identifier is the so-called root hash
of a Merkle hash tree over the content. For live streaming, the 
swarm ID is a public key.

Notes
-----
According to chapter 5 and chapter 6.1, it seems that it is not mandatory to use content integrity protection scheme.
The definition of swarm ID in the original text does not define how the ID is used in environment with the content integrity protection disabled.
It is possible to add new description on how swarm ID is defined in the content integrity protection scheme is disabled. 
Or, it is possible to remove the parts regarding content integrity protection.

We propose to remove "with content integrity protection enabled" part.
