H.263 Version 1 supports only a few fixed source formats (see table 6-25 in the visual part of the standard) and no custom formats. "160x120" is not supported, the only chance for you is to use sub-QCIF (128x96) or QCIF (176x144). -Harald -- ------------------------------------------------------------- Harald Fuchs Fraunhofer IIS-A email: fuchs@iis.fhg.de Department Studio phone: +49-9131-776-382 Am Weichselgarten 3 fax : +49-9131-776-399 D-91058 Erlangen (Germany) ============================================================= From Rakoch3 aol.com Thu Aug 2 12:58:21 2001 From: Rakoch3 aol.com (Rakoch3@aol.com) Date: Wed Jul 30 14:06:39 2003 Subject: [M4IF Technotes] stop spams please...

In the case of Levels 1 and up the tool set remains the same, only the parameters of using those tools change. In Level 0 for Simple and proposed Level 0 for Simple Scalable the tools become restricted. For example: Intra_dc_vlc_threshold shall be 0 so DC values cannot be encoded using AC VLC values. For exact restrictions look at Section 9 and Appendix N of the visual specification.

I do not know if ISO has published it yet though, I don't think so. MPEG-4 Simple Profile Level 0 has the following restrictions: a) The maximum frame rate shall be 15 frames per second; b) The maximum f_code shall be 1; c) The intra_dc_vlc_threshold shall be 0; d) The maximum horizontal luminance pixel resolution shall be 176 pels/line; e) The maximum vertical luminance pixel resolution shall be 144 pels/VOP; f) If AC prediction is used, the following restriction applies : QP value shall not be changed within a VOP (or within a video packet if video packets are used in a VOP). If AC prediction is not used, there are no restrictions to changing QP value. Other than Level 0, Simple Profile does not specify maximum frame size. It does specify buffer sizes which would for example not let you do CIF in Level 1.

What I would like to know is the encoding the VLC codeword with ESC type 1 and typ2 So, the original LEVEL and RUN like LEVEL_S - LMAX = sign(LEVEL) * abs(LEVEL) RUN_S - RMAX - 1 = RUN The left hand parts are the new (LEVEL_S - LMAX) and (RUN_S - RUNMAX-1) for TCOEF lookup and right hand sides of RUN and LEVEL are the result when we do the run length encoding.

If you change the extension to *.trif they should play. That is because the DMIF implementations in IM1 use the filename extension to guess the file format. At least that was the problem that I encountered.

MPEG-4 has adopted the core compression efficiency tools from H.263 like unrestricted motion vector, 4 MV etc. The additional tools of MPEG-4 are adaptive AC/DC prediction, resync markers, data partitioning, RVLC, non-linear quantization of DC coefficients, supporting separate VLC table for Intra macroblocks etc. These comparisons are between MPEG-4 simple profile and H.263 only. -ramkishor Architect - Video Digital Media Technology Division Emuzed Bangalore Division IndiraNagar,Bangalore www.emuzed.com ******************************************************************* Disclaimer : The information contained and transmitted in this e-mail is confidential information, and is intended only for the named recipient to which it is addressed.

I could not find it in the document. I understand that OpenML could be to MPEG-4 what OpenGL is to VRML, i.e. a set of low level APIs on which one can develop an MPEG-4 Browser. It seems to me that the goal is ambitious but that there is a strong demand for open framework for that. So, yes, let's see. An interesting sanity check for OpenML could be to implement an MPEG-4 browser using their APIs. It seems to me a perfect application for them. > Seems that all kinds of overlapping open formats are > appearing. I think > Scaleable Vector Graphics may be loosely related to Flash or > your BIFS. Have > you seen that yet? Comments? http://www.adobe.com/svg/ SVG, like Flash, SMIL or VRML are interesting but fragmented initiatives to provide solutions for interactive multimedia scene representation. The major drawbacks in this fragmentation are : - Although they are in general reasonnably good in there domains of expertise, these solutions are not integrated (ex : integration with streamed media, integration of 2D and 3D, integration of natural and synthetic content, ...). It is a serious concern for what is multimedia nowadays. For example, if you have a 2D app. and you want to grow with a bit of 3D because hardware allows for it and clients request it, you have to change completly your system. MPEG provides such integrated framework as well as bridges from these languages to MPEG (ex: all VRML can be compiled in MPEG, most of SMIL is integrated in XMT, the eXtensible MPEG-4 Textual Format, Flash and SVG can be compiled into BIFS). - These solutions are mainly dedicated to one type of environment, the Web, which is the delivery environment that imposes the easier constraints on the media. The MPEG architecture has been designed to be transport agnostic since the beginning and MPEG experts have designed efficient solutions for the delivery of MPEG in various environment (ex : IP, MPEG-2 transport, MP4 file, ...). None of the MPEG competitors can be as ubiquitous as easily, by design. None of them are as efficient in delivery environments where things such as bitrate and synchronization are important issues. Adapting an MPEG application to a given delivery environment has been made as easy as can be. - Finally, multimedia representation is not the only issue. To make a successfull applications you also need to deal with the protection of your media information, possibly metadata you want to attach to it, usage rights, ... To make this work well, serious integration (ex : IPMP-Intellectual Property Management and Protection Systems can now be attached to MPEG-4 content, MPEG-7 metadata can be associated to MPEG-4 streams ...). To my knowledge, this global vision is only available in MPEG.

Slice structure is just like Video-Packets in MPEG-4. We have the similar structures in H.261, H.263, MPEG-1, MPEG-2, MPEG-4. But, DataPartitioning is identifying groups of important data (with which we can reconstruct the MacroBlock reasonably partially with one partition itself) within one structure like this (in MPEG-4, this is VideoPacket), and grouping these data into partitions. Like, in one Video Packet, all MacroBlocks Headers into one partition, all DCT-data into another partition. According to the standard, we have 3-partitions.

Please be elaborative for this > perticular query. DMIF sits between the application and the transport. It abstracts the transport layer from the application, so that the app only needs to have one interface to the tranport layer. THen through DMIF instances, the app can talk to e.g. RTP, local disk, broadcast transparently. See http://www.m4if.org/public/MPEG-4Overview.zip Best, Rob
