The following errata report has been submitted for RFC2435,
"RTP Payload Format for JPEG-compressed Video".

--------------------------------------
Type: Technical
Reported by: Julius Richard Friedman <juliusfriedman@gmail.com>

Section: 3.1.5

Original Text
-------------
3.1.5.  Width: 8 bits

   This field encodes the width of the image in 8-pixel multiples (e.g.,
   a width of 40 denotes an image 320 pixels wide).  The maximum width
   is 2040 pixels.

3.1.6.  Height: 8 bits

   This field encodes the height of the image in 8-pixel multiples
   (e.g., a height of 30 denotes an image 240 pixels tall). When
   encoding interlaced video, this is the height of a video field, since
   fields are individually JPEG encoded. The maximum height is 65535
   pixels.

Corrected Text
--------------
3.1.5.  Width: 8 bits

   This field encodes the width of the image in 8-pixel multiples (e.g.,
   a width of 40 denotes an image 320 pixels wide).  The maximum width
   is 2040 pixels.

3.1.6.  Height: 8 bits

   This field encodes the height of the image in 8-pixel multiples
   (e.g., a height of 30 denotes an image 240 pixels tall). When
   encoding interlaced video, this is the height of a video field, since
   fields are individually JPEG encoded. The maximum height is 65535
   pixels.

Notes
-----
Use a divisor of 256 to determine the height, where 8 / 256 = 32.

Ensure FragmentOffset does not exceed 2^24, if it does then use 2^24 - value)

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party (IESG)
