This bit is shifted
The decoded image (prior to de-blocking filter) is also
stored for future motion compensation reference.
This flag is valid only for MPEG4 / H.263 case.
When H.263 case, if Annex J is turned on, this flag is
ignored and H.263+ Annex J de-blocking filter is
performed. If Annex J is turned off, MPEG-4 de-blocking
filter is enabled (same with MPEG-4)
ReorderEn R/W Enable display buffer reordering in H.264 decode case.
In H.264 case output decoded picture may be re-
ordered if pic_order_cnt_type is "0" or "1". In that case,
decoder must delay output display for re-ordering but
some applications (ex. Video telephony) don't want
such display delay.
Host may set this flag to "0" to disable output display
buffer reordering. Then BIT processor does not re-order
output buffer when pic_order_cnt_type is "0" or "1". In
pic_order_cnt_type is "2" or MPEG4/H.263 case, this
flag is ignored because output display buffer reordering
is not allowed.
If this flag is "1", BIT processor perform output decoded
picture reordering and output display is delayed in the
amount of [RET_DEC_SEQ_FRAME_DELAY] register's
value.
FilePlayEn R/W Enable file-play mode in decoder operation with frame-
based streaming.
DecDynBufA R/W Enable dynamic picture stream buffer allocation in file-
llocEn play mode
If this option is enabled in file-play mode, stream buffer
address given with DEC_PIC_RUN command will be
used instead of stream buffer address given with
DEC_SEQ_INIT. By using this dynamic allocation
feature, application can achieve higher efficiency in
streaming.
Set to 0
VC1_Reode R/W Re-ordering disable in VC-1 decoding
