Joint meeting with Requirements

xxxx	Review and updates of ARAF Requirements The document N12585 was updated to: - add user description support - add sensor data compression - add 3D cameras - add microphones - add environmental sensors - add support for point of interest - add support for remotely processing of signal descriptors	Seungwook Lee, Jinsung Choi, Bon Ki Koo
m31505	Draft requirement and use cases for the 3D printing metadata The contribution introduces a set of requirements for materials used in 3D printing. While acknowledging the growth of the 3D printing industry, the group expressed concerns about the lack of experts in the field participating to the standardization process. In order to ensure the quality of the standard and the deployment of it, it is necessary to have commitment from representatives of 3D printing industry to participate to the standardization process.

2. Session: 3D Audio and AR

Session	Thu 3DA and AR	14h-15h
At the 104^th MPEG meeting the 3DG Chair summarized the needs of an Audio Augmented Reality system as follows: Analyze scene and capture appropriate metadata (e.g. acoustic reflection properties) and attach it to a scene Attach directional metadata to audio object HRTF information for the user The audio augmented reality system should be of sufficiently low complexity (or we have sufficiently high computational capability) that there is very low latency between the real audio and the augmented reality audio. The 3DG Chair clarified that less than 50 ms is a realistic requirement for 3D audio latency. The 3DG Chair gave an example of Augmented Reality: a person has a mobile device with a transparent visual display. The person sees and hears the real world around him, and can look through the transparent visual display (i.e. “see through mode) to see the augmented reality (e.g. with an avatar rendered in the scene). The avatar has a pre-coded audio stream (e.g. MPEG-4 AAC bitstream) that it can play out, and ARAF knows its spatial location and orientation (i.e. which way it is facing). The required the audio metadata is: Radiation properties of avatar (i.e. radiation power as a function of angle and distance) The avatar audio could be presented via headphones or ear buds. The Audio Chair noted that ARAF may want to incorporate a head tracker so that the avatar can remain fixed within the physical world coordinate system. The 3DG Chair noted that if “see through” mode is used then the orientation of the mobile device screen would be sufficient. In that case, audio could be presented via the mobile device speakers. The Audio Chair noted that the avatar could function as a “virtual loudspeaker” in MPEG-H 3D Audio such that the 3D Audio renderer could be used for presentation via headphones. However, 3D Audio is not able to add environmental effects (e.g. room reverberation) that are separate from the avatar sound. Furthermore, 3D Audio cannot add such environmental effects based on listener location or orientation (e.g. reverberation changes when the listener moved closer to a reflecting surface). Yeshwant Muthusamy, Samsung, noted that KHRONOS and OpenSELS provide a 3D Audio API that does support e.g. reverberation based on user location and might offer a solution. However, the Audio Chair noted that ARAF does not know the acoustic properties (i.e. surface reflective properties) of the real-world environment (unless it can deduce them from the visual scene) and thus audio effects based on real-world environment is not possible, whether using MPEG-H 3D Audio or KHRONOS. 3DG experts will consider this problem and report back at a future joint meeting. The following steps are defined: Step 1: Integrate and test the BIFS 3D Audio nodes Step 2: Integration of the MPEG-H engine that will be able to synthetize the audio signal at a specific position Step 3: Investigate audio propagation of virtual sources taking into consideration the physical medium properties BIFS 3D exists in three implementations (Technicolor, Orange, Fraunhofer). Marius will ask the owners of the implementations for contributions. Uptates in Geneva, Octobre 2013: Topics: RENDERING: 1. Spatial audio in ARAF scenes by using the nodes: AcousticScene, AcousticMaterial, DirectiveSound, PerceptualParameters. What are the usage scenarios for these nodes? CAPTURE: 2. Microphone Sensor support in MPEG-V; arrays of microphones; ambisonic microphones, directional microphones. It is difficult to have sensors that are able to obtain the acoustic parameters. DETECTION & TRAKING: 3. Audio Scene Analyzer: identify a sound or sound properties and trigger an event based on this identification. Optionally, the sound (or a compact description of it) is used as an entry to a remote database (similar to CDVS). Question: what kind of audio properties can be used to model the context? MPEG-7 has low-level parameters that permit music recognition. There is nothing yet for Compact Descriptor for Speech. The research work on such compact description is still in progress, making on the standard on it is too early. 4. Sound sources separation and augmentation of individual sources. This is better supported with special type of microphones (check with Maurizio Omologo). 5. Audio actuator: directional speaker Note: there may be some legal issues with capturing the audio in a public places.

The summary of the RGC related activities is the following:

1. We investigated the need to include multiple models in the FU ED_BitPrecision.

Since the data is processed in a sequential manner, the emuation of multiple models can be done by setting the STATIC_PREFIX_SIZE parameter to value 0 and generating the proper sequence of "prefix_size" input tokens, one for each model.

The already defined FU in the spec is generic enough to cover all the cases. There is no need to update the document.
2. We finalized the design of Algo_ContextModeling_SVA_Indexes to be compliant with ED_AD for the SVA decoder case.

It will be included in the document as an update to the already existing one.

3. We centralized all the GTL reference software and uploaded it to MPEG SVN
4. We updated the reference software status table
5. We included the TFAN and SVA xdf code as an informative annex to the document (electronic insert)
6. We created a preliminary design of the SVA schematic to be included as an informative annex.

4. Session Joint with Requirements on 3D printer and ARAF v2 use cases and Req.

The digital representation of a 3D asset can include metadata that indicates the physical characteristics of the object to be used when using a 3D printer to create the physical object. Therefore, the designer of the document can specify these characteristics. Additionally, an intelligent component may interpret this data, together with user preferences and printer capabilities and indicate appropriate selections for the printing physical materials.

Resolution: Consider the 3D Printer as a 3D Actuator.

5. Session 3DG Plenary

Review of the liaison letters, review of all the output documents.

26. General issues

    1. General discussion

       1. Reference Software

It is recalled that the source code of both decoder AND encoder should be provided as part of the Reference Software for all technologies to be adopted in MPEG standards. Moreover, not providing the complete software for a published technology shall conduct to the removal of the corresponding technical specification from the standard.

Currently all the AFX tools published in the third edition are supported by both encoder and decoder implementation.

    2. Press Release: GTL FDIS

At the 106^th MPEG meeting, MPEG's Graphics Tool Library (GTL) - ISO/IEC 23002-4:2012 Amd. 1 has reached FDIS status and will be soon published as an International Standard. The MPEG GTL is a part of MPEG Reconfigurable Media Codec (RMC) framework.

The GTL consists of a collection of Functional Units (FUs) that implement generic or decoder specific functionalities. The compressed bitstream can be accompanied by the decoder network description and therefore, a run-time decoder is generated before the decoding starts. The network description can be constructed based on different types of constraints such as energy efficiency, adaptation to changing characteristics (network bandwidth, scene type, applications, …). GTL also makes possible the fast decoder prototyping that fits to content characteristics and usage scenarios.
One of the GTL objectives is to make possible the usage of different hardware and software platforms by locally generating the decoder implementation therefore taking advantage of the devices characteristics.
