Archive-name: mpeg-faq/part3 Last-modified: 1994/08/22 Version: v 3.2 94/08/22 Posting-Frequency: bimonthly BEGIN -------------------- CUT HERE --------------------- 3/6 SPIE conference on Video Compression for Personal Computers (to be held Feb 1994 in San Jose) Q. Is there a book on MPEG video? A. Yes, there will be a book published in Spring 1994 by the same authors who wrote the JPEG book (Bill Pennebaker, Joan Mitchell) with Didier Le Gall as an additional co-author. Q. Can motion vectors be used to measure object velocity? A. Motion vector information cannot be relaibly used as a means of determining object velocity unless the encoder model specifically set out to do so. First, encoder models that optimize picture quality form vectors that typically minimze prediction error and, consequentally, the vectors often do not represent true object translation. Standards convertors that resample one frame rate to another (as in NTSC to PAL) use different methods (field coding, edge detection, et al) that are not concerned with optimizing SNR vs bitrate. Secondly, motion vectors are not transmitted for all macroblocks anyway. Q. How do you code interlaced video with MPEG-1 syntax? A. Two methods can be applied to interlaced video that maintain syntactic compatibility with MPEG-1 (which was originally designed for progressive frames only). In the field concatenation method, the encoder model can carefully construct predictions and prediction errors that realize good compression but maintain field integrity (distinction between adjacent fields of opposite parity). Some pre-processing techniques can also be applied to the interlaced source video that would, e.g., lessen sharp vertical frequencies. This technique is not efficient of course. On the other hand, if the orignal source was progressive (e.g. film), then it is more trivial to convert the interlaced source to a progressive format before encoding. (MPEG-2 would then only offer superior performance through greater DC block precision, non-linear mquant, intra VLC, etc.) Reconstructed frames are re-interlaced in the decoder Display process. The second syntactically compatible method codes fields separately. Picture types are keyed to motion activity to aid efficiency of prediction. Q. How many cable box alliances are there? A. Many. To start with: Scientific Atlanta (SA), Kaledia, and Motorola: SA will build the box, Motorola the chips, and Kaleida the O/S and user interface (using ScriptX of course). Silicon Graphics (SGI), Scientific Atlanta, and Toshiba For the Time Warner's Orlando trial, SGI will provide the RISC (MIPS R4000) and software, SA will do the box again, and Toshiba will provide the chips. General Instruments (GI) and Microsoft: GI will make the box and Intel will supply the special low-cost 386SL processor on which a 1MB flash EPROM executable core of Microsoft windows and DOS will run. Microsoft will develop the user interface. Hewlett Packard (HP): HP will manufacture and/or design low cost, open architecture set-top decoder boxes (not a part of the Eon wireless deal). The CPU will explicitly not use a 80x68 based processor. [more details in installment 3] CLI and Philips: Compression Labs will provide the encoder technology and Philips will provide the decoder techology for an ADSL system whose transport structure will be put together by Broadband Technologies. ["These alliances subject to change at the whim of PR departments and market forces."] [Thanks to Steve Krause for assistance on box alliances]. Q. What is the rundown on public domain MPEG source software? A. There are two public domain source codes available: Berkeley encoder (v1.1) by Kevin Gong, Dan Wallace, Ketan Patel, Brian Smith, and Larry Rowe. Log, telescopic, and exhastive search variable rate operation designed for parallel machine operation Loeffler, Lightenberg, Moschytz "Practical fast 1-D DCT algorithms with 11 multipications" from ICCASP-89. Optimized for speed. Stanford encoder (v1.2) by Andy C. Hung Telescopic search SM-3 coding strategy and rate control Chen, Smith, Fralick algorithm or floating point direct matrix multiply. Optimized for flexibility. Stanford decoder does not include display functions. [more details in installment 3] Q. Is MPEG patented? A. Yes and no. Many encoding methods are patented. Blocking patents, that is, patents that are general enough to be unavoidable in any implementation have been recently identified. [installment 3] patent pool blocking patents method-specific patents (proprietary algorithms, architectures) Q. What are the tell-tale MPEG artifacts? A. If the encoder did its job properly, and the user specified a proper balance between sample rate and bitrate, there shouldn't be any visible artifacts. However, in sub-optimal systems, you can look for: Gibbs phenomenon/Ringing/Aliasing (too few AC bits, not enough pre-filtering) Blockiness (not considering your neighbors before quantizing) Posterization (too few DC bits) Checkerboards (DCT eigenimages as a result of too few AC coefficients) Colorbleeding (not considering color in encoder cost model) Q. Where are the weak points of MPEG video ? A. Texture patterns (rapidly alternating lines) sharp edges (especially text) [installment 3] Q. What are some myths about MPEG? A. There are two major myths that I am aware of: Block displacements: macroblock predictions are formed out of arbitrary 16x16 (or 16x8 in MPEG-2) areas from previously reconstructed pictures. Many people believe that the prediction macroblocks have boundaries that fall on interchange boundaries (pixel 0, 15, 31, 53... line 0, 15, 31, 53... etc.). In fact, motion vectors represent relative translations with respect to the target reconstruction macroblock co-ordinates. The motion vectors can point to half pixel co-ordinates which requires that the prediction macroblock to be formed via interpolation of pixels. Displaced frame (macroblock) difference construction: the prediction error formed as the difference between the prediction macroblock and source macroblock is coded much like an Intra macroblock (only without a DC value). The prediction may come from different locations (B-macroblocks) or fields (MPEG-2), but the DFD is always coded progressively as if it were a I-frame energy. ..and worst of all... Compression ratios: [installment 3] [real compression ratios are in the range of 16:1 to 30:1] -------- Subjects in future installments of the FAQ: Who are the people and companies behind MPEG?

MPEG therefore confirmed that it is on schedule to produce, by November 1993, Committee Drafts of all three parts of the MPEG-2 Standard, for balloting by its member countries. To ensure that a harmonized solution to the widest range of applications is achieved, MPEG, an ISO/IEC working group designated ISO/IEC JTC1/SC29/WG11, is working jointly with the ITU-TS Study Group 15 "Experts Group for ATM Video Coding." MPEG also collaborates with representatives from other parts of ITU-TS, and from EBU, ITU-RS, SMPTE, and the North American HDTV community. MPEG-2 Video MPEG is developing the MPEG-2 Video Standard, which specifies the coded bit stream for high-quality digital video. As a compatible extension, MPEG-2 Video builds on the completed MPEG-1 Video Standard (ISO/IEC IS 11172-2), by supporting interlaced video formats and a number of other advanced features, including features to support HDTV. As a generic International Standard, MPEG-2 Video is being defined in terms of extensible profiles, each of which will support the features needed by an important class of applications. At the March MPEG meeting in Sydney, the MPEG-2 Main Profile was defined to support digital video transmission in the range of about 2 to 15 Mbits/sec over cable, satellite, and other broadcast channels, as well as for Digital Storage Media (DSM) and other communications applications. Building on this success at this week's New York meeting, MPEG experts from participating countries in Asia, Australia, Europe, and North America further defined parameters of the Main Profile and Simple Profile suitable for supporting HDTV formats. This week the MPEG experts also extended the features of the Main Profile by defining a hierarchical/scalable profile. This profile aims to support applications such as compatible terrestrial TV/HDTV, packet-network video systems, backward-compatibility with existing standards (MPEG-1 and H.261), and other applications for which multi-level coding is required. For example, such a system could give the consumer the option of using either a small portable receiver to decode standard definition TV, or a larger fixed receiver to decode HDTV from the same broadcast signal. This week's accomplishments in New York mean that the technical definition of MPEG-2 Video has been completed. This was a critical milestone, and shows that MPEG-2 Video is on schedule for a Committee Draft in November. MPEG-2 Audio MPEG is developing the MPEG-2 Audio Standard for low bitrate coding of multichannel audio. MPEG-2 Audio coding will supply up to five full bandwidth channels (left, right, center, and two surround channels), plus an additional low frequency enhancement channel, and/or up to seven commentary/multilingual channels. The MPEG-2 Audio Standard will also extend the stereo and mono coding of the MPEG-1 Audio Standard (ISO/IEC IS 11172-3) to half sampling-rates (16 kHz, 22.05 kHz, and 24 kHz), for improved quality for bitrates at or below 64 kbits/s, per channel. This week in New York, MPEG produced an updated version of the MPEG-2 Audio Working Draft, and is on track for achieving a Committee Draft specification by the November MPEG meeting. The MPEG-2 Audio multichannel coding Standard will provide backward-compatibility with the existing MPEG-1 Audio Standard (ISO/IEC IS 11172-3). Together with ITU-RS, MPEG is organizing formal subjective testing of the proposed MPEG-2 multichannel audio codecs and up to three non-backward-compatible (NBC) codecs. The NBC codecs are included in order to determine whether an NBC mode should be introduced as an addendum to the standard. If the results show clear evidence that an NBC mode improves the performance, a formal call for NBC proposals will be issued by MPEG, with a view to incorporate these features in the audio syntax. MPEG-2 Systems MPEG is developing the MPEG-2 Systems Standard to specify coding formats for multiplexing audio, video, and other data into a form suitable for transmission or storage. There are two data stream formats defined: the Transport Stream, which can carry multiple programs simultaneously, and which is optimized for use in applications where data loss may be likely, and the Program stream, which is optimized for multimedia applications, for performing systems processing in software, and for MPEG-1 compatibility. Both streams are designed to support a large number of known and anticipated applications, and they retain a significant amount of flexibility such as may be required for such applications, while providing interoperability between different device implementations. The Transport Stream is well suited for transmission of digital television and video telephony over fiber, satellite, cable, ISDN, ATM, and other networks, and also for storage on digital video tape and other devices. It is expected to find widespread use for such applications in the very near future. The Program Stream is similar to the MPEG-1 Systems standard (ISO/IEC 11172-1). It includes extensions to support new and future applications. Both the Transport Stream and Program Stream are built on a common Packetized Elementary Stream packet structure, facilitating common video and audio decoder implementations and stream type conversions. This is well-suited for use over a wide variety of networks with ATM/AAL and alternative transports. This week in New York, MPEG completed definitions of the features, syntax, and semantics of the Transport and Program Streams, enabling product designers to proceed. Among other items, the Transport Stream packet length was fixed at 188 bytes, including the 4-byte header. This length is suited for use with ATM networks, as well as a wide variety of other transmission and storage systems. MPEG-4 Work on a new MPEG initiative for very low bitrate coding of audiovisual programs has been approved by unanimous ballot of all national bodies of ISO/IEC JTC1. This work will begin officially at the next MPEG meeting in Brussels in September 1993. It is scheduled to result in a draft specification in 1997. This work will require the development of fundamentally new algorithmic techniques. In conjunction with the MPEG meeting this week in New York, a one-day seminar was held on current research ideas applicable to low bitrate coding. Demonstrations and papers were presented on a number of techniques, including model-based image coding, human interaction with multimedia environments, and low-bitrate speech coding. When completed, the MPEG-4 standard will enable a whole spectrum of new applications, including interactive mobile multimedia communications. =========================================================================== II | PROFESSIONAL SOFTWARE =========================== The named tools are: MPEG Encode XingSound XingCD PC-Hurricane NVR-Toolkit ------------------------------------------------------------------------------- II.1 | DOS ----------- Ingenieurbuero Gatz & Hartmann, Fehrbelliner Str. 32, 13585 Berlin, GERMANY Tel: 030- 344 23 66 or 030-375 55 68 FAX: 030- 344 92 79 or 030-375 56 55 email to: harti@mikro.ee.tu-berlin.de The MPEG Encoder is available starting from 349.-DM incl.

Thanks ! --------------------------------------------------------------------------- XingCD is here ! It is the first AVI to MPEG Encoder, which allows you to make MPEG system streams from AVI movies. This means, you can directly use a Motion JPEG capture board at 352x288 resolution to capture Realtime video, edit it with Adobe Premiere for Windows and make a Video CD out of it, using the new XingCD Encoder. The XingCD Encoder is software only, so there is no further hardware required. It converts the AVI Video file to MPEG Video and the sound WAV file to MPEG Audio and interleaves (multiplexes) these 2 bitstreams into an MPEG system layer bitstream, so it could be played back via a REEL MAGIC card for instance or the new Inside Technology MPEG player card for the PC. The new MPEG Encoder supports full IBP format and is compatible with the ISO11172 MPEG system layer description. Price is 995.-US$, but this is still cheaper than a 20K US$ realtime MPEG capture board..... It can also encode from single TGA or BMP pics and it supports various output format of: 352x240, 352x288, 160x120 and custom output resolution. Rescales source to desired ouput resolution etc... Encode Process runs in the background. I hope, we will get soon many "fresh" MPEG Video CDs ! --------------------------------------------------------------------------- Gatz and Hartmann proudly presents: PC-Hurricane Win3.x Winhurri Version 1.5 This is our new control program for the moviegrabber board PC-Hurricane ============ This version 1.5 only runs in Hicolor modes 32K or 64K colors ! So use these Windows Hicolor drivers to use this piece of software. Functions: ---------- 1. You can digitize video movies in realtime (up to 25 frames/second) into Extendend Memmory and play them also back in realtime with this Winhurri program. Now you can also do Harddisk-Video-Recording in realtime up to 384x288 screen size (full field resolution ) ! 2. You can save every single frame or the whole movie in one shot to the harddrive. 3. Due to the DIB or BMP output you can load the DIB sequence directly into the VideoEditor of Microsoft's Video for Windows(tm) program and generate an compressed AVI movie. The BMP output is for the Xing Technology MPEG encoder, so you can choose to make AVI or MPEG movies from the digitized raw data. 4. You can watch television with this card by connecting a tuner and clicking the VIEW button. At 160x120 screen size it gives you realtime video display without the need of an feature connector cable to your VGA card or the hassle to be unable to use the highest Hicolor windows driver. So you can watch TV while working in a windows resolution of e.g. 1024x768x64K colors and still doing word-processing or picture editing in Hicolor. Normal Overlay boards only support up to 256 colors windows drivers or only 640x480x32K colors, but not 1024x768x64K colors Noninterlaced! (like with the new Genoa VideoBlitz card with the Weitek P9000 chipset) Future versions: ---------------- We are already working on integrating WAV sound digitizing in realtime together with the video grabbing by using any installed soundcard under windows. This will allow synchroneous digitizing of sound and video in one shot. You can then save the DIB sequence and a WAV file and do an AVI movie with sound in one shot ! email to: harti@mikro.ee.tu-berlin.de PC-Hurricane in this moment sells for 499.-DM incl. 15 % VAT in Germany. Together with the Xing Technology MPEG Encoder and player it is 699.- DM incl. 15 % VAT in Germany. Foreign customers could get it by VISA card payment. It is 299.-US$ including airmail delivery to you. Together with the Xing MPEG Encoder and Player software for Windows it sells for 449.- US$ incl. shipping and handling. --------------------------------------------------------------------------- II.3 | UNIX ------------ [ Its really nice software, but its expensive !

There are several nice and long MPEG-movies to ftp !!! ] [ If you require a demo version, please send mail to support@nvr.com ] From: Chris Jacobson <chrisj@dinghy.nvr.com> Subject: Re: THE MPEG-FAQ - Version 2.0 Date: Thu, 13 May 93 10:31:32 -0700 North Valley Research Digital Media Systems North Valley Research is pleased to announce immediate availability of a family of products for working with video and other time-based media in a UNIX environment. These products are the first, affordable software products that enable the end user to take video and audio all the way >from video camera or tape to an MPEG sequence that can be played back in real-time on most Sun SPARCstations. Starting now until May 5th, 1993, individual products can be purchased for $150 in quantities of 30 or more; or under $300 for quantity 1. These software products have well-designed Motif user interfaces and a robust architectural design. The first set of products is sold as a kit, and consists of three user interfaces: - The Player. This tool provides a viewing mechanism for working with + MPEG sequences + analog video (requires the Parallax XVideo board) + JPEG movies (requires the Parallax XVideo board with JPEG option) - The Recorder. This tool enables the user to peruse analog material with an interface very similar to the Player, but in addition, allows you to create JPEG movies using the JPEG hardware on the Parallax XVideo board. - The Compressor. This tool allows you to choose input files, specify the compression characteristics and finally, compress them with our software MPEG compression engine. The MPEG playback mechanism is purely software, requires no special framebuffer, and depending on the size of picture, the size of the window and bandwidth of the bitstream, can run at 6 - 30 fps with synchronized audio. The color is dithered from 19 bits down to 7 bits, gamma-corrected, with real-time adjustments for contrast and brightness. The displayed window can be one or four times the size of the MPEG sequence picture size. For example, a sequence compressed at 320x240 can be played back at 320x240 or 640x480 (depending on the performance of the host computer). Both the MPEG compression and playback mechanisms support: + variable I:P:B ratios + variable picture sizes from 64x48 to 320x240 + variable and fixed bit rate + three motion estimation algorithms (Jain & Jain and two Exhaustive methods) The MPEG compressor is relatively fast for compression that includes motion estimation, and depending on the input stream and the selected compression parameters, can compress a twenty second sequence in as little as an hour. The JPEG record and playback is accomplished with the aid of the Parallax XVideo board. Recording and playback of JPEG movies is controlled by a special software engine that always keeps the audio and video synchronized. Recorded sequences may be "running records" from a camera or broadcast, or assembled from a controllable video source with in and out points. Both the Player and Recorder support Sony's ViSCA/LANC, and Pioneer 4400 disc players (and other compatible models). VideoMedia's VLAN will be added in the future.

"Funky" is copyright Juergen Herre 1994. You may use "Funky" for all evaluation purposes of this shareware product. You may not use "Funky" for commercial purposes (e.g. radio broadcasting). This package is distributed as shareware. You may work with the package for 30 days for evaluation purposes. If you want to use this package after the evaluation period, you are required to register the package (see information in the file REGISTER.TXT). You may give copies of this package to other people as long as no file is changed and no file is omitted. The programms are written for IBM-PCs or Compatibles with MS-Dos. While L3ENC.EXE and L3DEC.EXE should work on practically any PC, the other programms require a 386 type CPU plus hardware floating point support. Especially for the encoder, a 486DX33 or better is recommended. On a 486DX2/66 the performance of the software-only decoder is about 33% of the performance necessary for real time audio processing. The encoder needs about 30 minutes to encode a 1 minute audio data file. These figures assume coding/decoding of stereo audio material at 44.1 kHz/sec.

Its based on the MPEG-decoder called "mpeg_play" by the Berkeley Research Group. The basic idea was coming from the PPM-patch by Jef Poskanzer. Many thanks to both. SHAREWARE --------- MPEG2PPM is inexpensive shareware. If you are continuing using it after a 30 day trial-period, please send a letter containing the filled and signed registration-form and the little donation of 10 $ or 15 DM in cash to the adress below. ATTENTION: The dots the shareware version of MPEG2PPM produces are just delay, to force you to register. ATTENTION: A registration is recommended for commercial use. ATTENTION: The full-licenced version is restricted to a local area netword (company) or a privat single host. MPEG2PPM will decode a (video-only) MPEG-I-stream and extract the rebuild frames as PPM-files (Portable Pixmap). The extracted frames will be numbered starting from zero (0), the first part of the filename is derived from the original MPEG-stream, the files extension will be .PPM. The final PPM-files will be in 24-bit-format. MPEG2PPM expects MPEG-1 video streams only. It can not handle multiplexed MPEG streams or video+audio streams. The converter uses the paris entropy coding table set (which I believe to be the MPEG-1 standard). MPEG2PPM was developed by PHADE Software Inh.

Changes from VMPEG 1.0 to VMPEG 1.1: - 20% speed gain (code streamlining) - improved image quality (higher IDCT accuracy) - True Color display - support of system layer MPEG streams - more drivers included Features: - full MPEG-1 video standard (ISO 11172-2): I,P,B frames of arbitrary size; no restriction to 160x120 or I-frame-only sequences - also plays system layer (ISO 11172-1) files - "high" speed: e.g. 16 frames/s on a 386DX/33 for a 160x120 I frame sequence (mjackson.mpg); about the speed of mpeg_play running on a Sparcstation1+ - supports VGA and a variety of SVGAs - '386 or '486 processor required (i.e. no '286); based on the DOS extender GO32.EXE by DJ Delorie END ---------------------- CUT HERE --------------------- 3/6
