[Mp4-tech] output of deblocking filter

[Robin Zoo]

Dear experts:
I noticed the following descriptions in MPEG2
standard:
"The output of the decoding process, for interlaced
sequences, consists of a series of reconstructed
fields that are separated in time by a field period"
"In progressive sequences each picture in the sequence
shall be a frame picture. The sequence, at the output
of the decoding process, consists of a series of
reconstructed frames that are separated in time by a
frame period"
I think the statements are true in H.264 decoding
process though I didn't found similar description.
Here is my question, for H.264 interlaced sequences,
if PAFF and MBAFF are in use, the output of deblocking
filter are mixed frame and field pictures which even
include frames containing mixed field or frame
macroblock pairs. Interlacing of frame or macroblock
pairs has to be done before sending the decoded pixel
for display. Is it true?
thanks a lot!
