[Mp4-tech] about H.264/AVC standard document

[=?big5?B?TGkuTWcgW6f1slHB4l0=?=]

Dear experts, 
    I'm also confused about the case of MacroBlock to Slice group of 8.2.2.8 in ITU-T H.264 (2003/05) version.
    8.2.2.8:
    "Otherwise (frame_mbs_only_flag is equal to 0 and mb_adaptive_frame_field_flag is equal to 0 and field_pic_flag is
     equal to 0), the macroblock to slice group map is specified by:
    MbToSliceGroupMap[ i ] = mapUnitToSliceGroupMap[ ( i / ( 2 * PicWidthInMbs ) ) * PicWidthInMbs
    + ( i % PicWidthInMbs ) ]"
    when parameter : frame_mbs_only_flag is equal to 0 and mb_adaptive_frame_field_flag is equal to 0 and field_pic_flag is
     equal to 0 --> it means this is a coded frame with all the MacroBlocks are field MarcoBlocks ?
BR,
MG Li

With field_pic_flag equal to 0 and mb-aff turned off, I think you're talking about an ordinary frame.
BTW you should get ahold of something more recent than G050r1.  That's from several iterations ago.

	hello,experts:
	     In h.264/AVC standard document(JVT-G050r1,Page 86) there is a paragraph about FMO decoding:
	    "Otherwise (frame_mbs_only_flag is equal to 0 and mb_adaptive_frame_field_flag is equal     to 0 and field_pic_flag is equal to 0), the macroblock to slice group map is specified     by:
	    MbToSliceGroupMap[ i ] = mapUnitToSliceGroupMap[ ( i / ( 2 * PicWidthInMbs ) ) *         PicWidthInMbs + ( i % PicWidthInMbs ) ]                  (8-27)"
	     who can tell me what's the picture type(frame or field or others) if "frame_mbs_only_flag is equal to 0 and mb_adaptive_frame_field_flag is equal to 0 and field_pic_flag is equal to 0"?
	     thanks!
