AVC-443R	REPORT OF THE TENTH MEETING IN TORINO and ROMA - PARTS I and II 
	(CHAIRMAN)
AVC-444R	REPORT OF THE TENTH MEETING IN TORINO and ROMA - PART III (CHAIRMAN)

These two documents report the outcome of the sole and joint sessions held in January 1993.

AVC-445b	Test Model 4 (Test Model Editing Committee)

Achievements and clarification obtained at the Roma meeting were incorporated into Test Model 4, and several core experiments were defined for action.

AVC-446	MPEG-2 Working Draft - Video Part - Version 1, Revision 2
	(Working Draft Editing Committee)
AVC-449	MPEG-2 Working Draft - Video Part - Version 3 (Working Draft Editing Committee)

Working Draft is a document which should evolve into Committee Draft in November 1993.  This video part is substantially structured as follows;

     -	Profiles and levels
     -	Video bitstream syntax and semantics
     -	The video decoding process
     -	Defined profiles and levels

AVC-447	Liaison statements (SGXVIII)

Three liaison statements we re generated at the January 1993 meeting of SGXVIII (now ITU-TSS SG13) regarding the following items;

     -	Update of the IVS Baseline Document
     -	Request of information on maximum allowable AAL delay for supporting H.320 terminals in B-ISDN by introducing a forward error correction in AAL Type 1.
     -	Traffic parameters for average cell rates, particularly measuring time constants of seconds or more
     -	Interworking issues when using CLP bit and resource allocation options

AVC-448	IVS Baseline Document (D. Dorman, Editor)

This is a version revised at the January 1993 meeting of the Working Parties of SGXVIII (now ITU-TSS SG13) to incorporate inputs from other groups and SGXVIII achievements.  The principal amendments include:

     -	revision of standardization time tables for SGXVIII, SGXV, TG CMTT/2,
     -	revision of summary table for multimedia multiplex methods,
     -	updated and prioritized open issues list for multimedia Recommendation I.374,
     -	inclusion of possible functions for video signal support of AAL Type 1 and Type 2,
     -	list of open issued generated at the IVS Technical Session in October 1992.

AVC-450	Selecting rule of reference pictures in the low delay mode (Japan)

Taking into account of the case to use skipped pictures, a consistent rule of selecting reference pictures is proposed for forward and backward prediction in Frame pictures and Field pictures.  Forward prediction refers to the latest available coded picture(s) while backward prediction refers to the latest coded picture, if it exists, which follows the current picture in the source order but precedes in the coding order 

AVC-451	Clarifications of VBV operation (Japan)

This document first clarifies VBV related items when picture skipping is involved and then usage of the vbv_delay and VBV operation are specified.  Encoding operation and setting of vbv_delay are also described which satisfy the VBV specifications.  Modified description for "Video Buffer Verifier" and "Low Delay Coding" in WD is provided.

AVC-452	Syntax modification for VBR operation (Japan)

In order to acommodate VBR in the Main Profile, this document proposes extension of bit_rate filed to vbr_mode (1 bit), bit_rate (18 bits) and ave_rate (18 bits) and extension of vbv_buffer_size to 16 bits.  How to set vbv_delay in VBR operation is also discussed concluding that further study is required.

AVC-453	Report of non-8x8 DCT experiment (Japan)

Experimental results are reported which indicate that 8x8/8x1 DCT improves field-picture coding and frame-picture coding by 0.47-0.75 dB and 0.22-0.40 dB, respectively.  It is also reported that if 8x8/8x1 DCT is used, further use of Frame/Field DCT gives only 0.02-0.31 dB improvements.

AVC-454	Report of AC-leaky prediction (Japan)

Experimental results for AC-leaky prediction and more frequent intra DC refresh are given to show that the technique is efficient and effective for temporal localization of errors.

AVC-455	Fix for the noisy background problem in leaky prediction(Japan)

Experimental results are reported that a combination of periodic stronger leak and adaptive MB quantization for background areas give SNR performance and subjective quality very close to the intra slice method.

AVC-456	Experiment on leaky prediction (Japan)

Experimental results are reported on comparison between TM3, AC-leaky prediction and Adaptive DC quantization, concluding that both of the leaky prediction methods could not achieve as good picture quality as that of TM3 at 4 Mbit/s due to remaining background noise.

AVC-457	Experiments on data partitioning by PBP (Japan)

Experimental results are reported on reconstructing pictures only from the base layer information partitioned by PBP, concluding that adequate quality for practical use can not be obtained due to accumulation of mismatch errors even if the intra slice updating is used.

AVC-458	Experiments on error concealment with Data Partitioning  (Japan)

Experimental results are reported on error concealment in the two layer partition by PBP (base and additional bitstreams) when cell loss takes place only in the additional stream.  It is concluded that simple error concealment provide sufficient error resilience for PBP value 0 inter macroblocks.  For intra macroblocks, more coefficients needed to be transmitted via the high priority channel for which suggested changes in the PBP semantics are given.

AVC-459	A study on forward error correction method in AAL Type 1 (Japan)

Application of RD(48,44) code to AAL Type 1 is considered for cell loss correction and random eerror correction in a cell.  This FEC provides for transmission efficiency of 91.5% and error correction processing delay of 32 ms at 384 kbit/s.

AVC-460	Quantization of Intra-compatible MBs (Japan)

Experimental results are reported on applying intra quantization to intra-compatible macroblocks for both interlace-interlace and interlace-progressive cases.  Though 0.6-0.87 dB gain is obtained for I pictures with this method, improvements at the total sequence is not so large as to justify such change from the current quantization.

AVC-461	Up-sampling methods for spatial scalability (Japan)

Three methods of specifying upsampling filters for spatial scalability are discussed; 1) specifying unique set of filters, 2) downloading the coefficients from encoder to decoder, 3) tolerating filter coefficient mismatch between encoder and decoder.  In the interest of hardware overload, the second method is concluded as undesirable.

AVC-462	VBR coding under Usage Parameter Control (Part 2) (Japan)

Hardware experimental results are reported for the relationship between the encoder buffer delay and the Leaky Bucket Size, concluding that apart from the obvious relationship (e.g. encoder buffer delay is inversely proportional to the Peak Rate) Leaky Bucket Size does not have critical effect on encoder buffer delay for the applied coding parameter control method (VBR mode if Leaky Bucket occupancy < 90 % of Leaky Bucket Size, otherwise CBR operation).

AVC-463	Consideration of MPEG-1 Systems as multimedia multiplexing for audiovisual 
	communications (Japan)

A case study of applying MPEG-1 Systems to the multimedia multiplex for high quality videoconferencing indicates that it is a possible method.  Several items are discussed; constraint on number of packets per second which determines packetizing delay, correspondence between medium and stream_id which influences cross application bitstream interchange, implementation, impact of cell losses and rate control.  It is concluded that necessary changes to the MPEG-2 program mux be urgently discussed and decided.

AVC-464	Relation between MPEG-2 transport mux and ATM/AAL (Japan)

An MPEG-2 transport mux being currently considered is compared with ATM/AAL Type 4 in functionality, indicating similarity to a great extend and encouraging further study.

AVC-465	Video source clock recovery using network clock (Japan)

Use of high quality network clock, if commonly available to the encoder and decoder, is discussed for video clock recovery.  As a conclusion, addition of a one bit flag is proposed to indicate which of the internal or external sources is used by the encoder.

AVC-466	Preliminary DSM control command requirements (PTT Research - NL)

By listing a number of control commands related to the network database access, discussion is encouraged on an appropriate positioning of the MPEG specific controls in the complete control command picture.

AVC-467	Interworking and complexity requirements on scalable video coding algorithms 
	(PTT Research - NL)

Pel-split and DCT-split schemes to achieve scalable video coding are compared in terms of interworking, complexity, flexibility and visual quality, leading to the former as a conclusion.

AVC-468	System multiplexing and priorities (PTT Research - NL)

Relationship between the MPEG-2 transport mux and B-ISDN functionalities is discussed with a focus on the transmitting priority.

AVC-469	Stereoscopic video transmission: a future application of spatial embedded coding 
	(PTT Research - NL)

Stereoscopic video transmission is given as an effective application of the spatial scalable embedded coding, where disparity compensated prediction is used to improve coding efficiency of the second channel.

AVC-470	MPEG-2 syntax (F, UK, B, I, N, D, NL, CH)

A proposal is made to maintain hooks in the MPEG-2 syntax for spatial scalability/compatibility for providing HD/ED/SD/LFDV and communication applications.

AVC-471	Variable slice sizes vs small fixed slice sizes (Australia)

This contribution considers the effect of trying to match the length of a slice to a multiple of the cell payload length by varying the number of macroblocks within a slice and to start a slice as soon as possible after the start of a cell.  A number of different multiples of the cell payload length are investigated to determine the change in overall sequence quality and average number of cells in a slice.  Error resilience of this approach is compared with that of a fixed number of macroblocks per slice, resulting in no significant difference.

AVC-472	Cell loss resilience of data partitioning (Australia)

Experimental results are presented for two layer data partitioning by the PBP method.  First, portions of the bits in the lower layer are given for different values of PBP.  Then, error resilience experiments are reported comparing non-partitioned and partitioned streams, summarizing that the data partitioning offered improved quality under cell loss even when only one priority level is used and that the quality improvement was more noticeable under high cell loss conditions.

AVC-473	Report of Ad-hoc Group on ATM Cell Loss Error Resilience (Australia)

This document is a report of the adhoc group activities established at the Rome meeting, which contains a proposed informative text for error resilience techniques in WD covering error concealment (decoder only and encoder assisted), spatial localization and temporal localization.

AVC-474	Bitsavings on the prediction_weight_code (BT, PTT Research)

Based on the coding efficiency gain for the prediction_weight_code of 1.04 % in the top layer of 1.15+2.85 Mbit/s environment, differential coding like quantizer_scale  is proposed.

AVC-475	MPEG Systems and B-ISDN (Australia)

After comparing layered protocol models between B-ISDN and MPEG systems under consideration, AAL Type 2 possibilities and relevant MPEG-2 systems functions are discussed.  As a conclusion, it is proposed that a layered MPEG-2 systems protocol model be defined which will allow the service in a lower layer to be provided by further MPEG-2 systems layers, or an appropriate B-ISDN layer.

AVC-476	Data Partitioning and the Main Profile (Australia)

Desirability is sated that the main profile decode be able to handle two partitions because this will provide improved performance at a small increase in decoder complexity.

AVC-477	Layered coding informative text (Australia)

Description for layered coding is given to provide for information on three strategies; data partitioning, frequency scalable pyramid, spatial scalable pyramid.  As an illustration of error resilient coding, a two layer data partitioning scheme and the use of two channels with different error performance are detailed.

AVC-478	Effectiveness of Data Extraction for Interlaced Source Material (Australia)

Experimental results are reported for two modes of 4x4 data extraction from coded Bus sequence; field mode with simple extraction and frame mode with 4x3+4x1 extraction.  It is concluded that the former method leads to a better quality extracted image.

AVC-479	Evaluation of Scalable Coding Schemes (Australia)

Two scalable coding approaches, frequency scalable and spatial scalable, are compared with simulcast concerning interworking capabilities, coding performance, network issues, compatibility with existing standards hardware complexity, functionality and applications.  It is concluded that though both methods can provide layered coding with resolution scalability, they do not serve as alternatives; emphasis on flexibility and compatibility leads to spatial scalable scheme, emphasis on efficiency and simplicity leads to frequency scalable scheme.

AVC-480	Quantization of spatially scalable prediction errors (BT)

Experimental results are reported for comparison between four quantization methods for 1.5 + 2.5 Mbit/s compatible coding; 1) normal quantization for all transform coefficients and the inter weighting matrix, 2) normal but with a step size of 8, 3) normal but with intra weighting matrix, 4) DC-8 + intra weighting matrix.  As a conclusion, it is proposed that the first quantization method for spatially scalable macroblocks be standardized.

AVC-481	The use of MPEG-2/H.26X for low bit rate applications (BT)

This document first argues that MPEG-2/H.26X should support low bit rate operations as it is a generic standard.  Then, limitations of the current syntax and some proposed changes are provided; 1) skipping any macroblock be allowed, and all macroblock coding parameters have default values, 2) picture skipping with no data at all be allowed, 3) indication of required maximum decodable rate be included in the sequence layer.

AVC-482	Enhancement of spatial scalability for reduced cost decoders (BT)

This document describes the current spatial scalable scheme and a variation of it that allows reduced cost decoders and show that the two schemes can be merged into a hybrid scheme to allow the use of reduced cost decoders.  The two schemes are compared in terms of implementation aspects and error resilience.

AVC-483	Sequence Layer Syntax (BT)

This document describes some of the limitations of the current sequence level syntax and proposes changes to overcome these limitations; 
1)	to allow change of prediction weighting matrices when sequence data is repeated, 
2)	to allow user data to appear before extension data and for sequence header data to occur without the to have preceding group of pictures and intra data,
3)	to make it a syntax element,
4)	to give the same status to sequence_data, pictures, extension_data, and user_data.
5)	to attach syntax diagrams to the standard,
6)to include profile and level ID instead of constrained parameter flag.

AVC-484	List of open issues, Version 2 (Chairman)

This is an updated version of AVC_436.  Open issues are listed with description of options, status, input required. aimed Recommendation, applications and target date according to the following categories;
	- framework for video coding standardization,
	- picture format,
	- video coding,
	- VBR vs CBR,
	- interface with networks,
	- end-to-end signalling,
	- multipoint communication system,
	- B-N interworking,
	- audio coding.
Background information such as system configuration, applications, milestones and target date (priority) is also contained.  

AVC-485	Experimental results with AC leaky prediction (AT&T)

Experimental results are reported concerning quality without cell losses or channel changing, speed of channel changing and quality with cell losses.  Fast forward and fast reverse modes using AC leak is also discussed.

AVC-486	Harmonising/combining low complexity, error resilience, scalability, image quality and 
	compatibility (PTT Research)

Configurations of decoder and encoder are discussed which allow integration of low complexity, error resilient, SNR scalability, resolution scalability and compatibility without changing the current macroblock layer syntax.

AVC-487	CCITT patent policy and MPEG-2 patent status (Siemens AG)

It is pointed out that technical proposals should include patent information according to the CCITT patent policy.

AVC-488	Results on TM4 prediction Core Experiment on mod. SVMC-Prime (Tektronix)

Experimental results are reported on SNR among prediction modes; Frame/Field, Frame/Field,/Dual-prime, and Frame/Field/Dual-prime/SVMC-prime.  As a conclusion, it is recommended that SVMC-prime be dropped from further considerations.

AVC-489	Some results on Frequency scalability Experiments I.4 (Tektronix)

Experimental results are reported on multichannel scalability using Scalable Side Information syntax extensions; three layers (1/4, 1, 1) and two layers (1/4,1), (1/16,1) with lower scale layer reference signal derived from field DCT subsampling.  It is concluded that the SSI syntax should support field or field/frame adaptive processing since frame based coding shows less coding efficiency for fast motion sequences, and that Extended MQUANT may be required for difficult to code sequences at constrained low bit rates.

AVC-490	H.26X error resiliency based on data partitioning and concealment (Tektronix)

Experimental results are reported for the two layer partition of PBP_1(0) and PBP_1(2) with motion interpolation concealment under cell loss ratio of 10**(-3).  It is concluded that a combination of data partitioning and concealment techniques provide a powerful and yet simple tool for cell loss protection.

AVC-491b	Test Model 5 (Test Model Editing Committee)

This is a revision reflecting the achievements obtained at the Sydney meeting.

AVC-492	Revised syntax and semantics for MPEG-2 video (Video syntax sub-group)

This is a delta document to the Working Draft (AVC-449) containing specifications for Main Profile at Main Level which has been frozen at the Sydney meeting.

AVC-493	MPEG-2 Systems Working Draft (Systems Committee)

This is a revised document of WD which reflects the achievements at the Sydney meeting.

AVC-494	Simulation results on CTV/HDTV compatible coding (ETRI)

Experimental results are reported for comparison between pyramidal coding and spatio-temporal compatible coding.  Both are coding HDTV (1920x1024 luminance pels, 4:2:2) and embedded CTV (960x512 luminance pels, 4:2:2).  It is concluded that both performance of compatible coding methods is quite similar and that both schemes give quite compatible picture quality.

AVC-495	Multi-channel information carried by Systems layer (Australian UVC, IBM, Tektronix)

It is discussed that certain basic information describing the multi-layer video need be carried in the Systems layer; at t he very minimum a service mapping table which relates packets and multi-layer entry types such as FSn (frequency scalable layer n), SSn (spatial scalable layer n) and DPn (data partitioning layer n).
