Summary of S4-260213: Template for Targeted Application and Services

Document Overview

This contribution from Xiaomi proposes a standardized template for documenting media streaming application scenarios within the FS_QStream_MED study. The document aims to provide structure and consistency when contributors propose new application scenarios for evaluation.

Main Technical Contributions

1. Study Objectives Context

The document references the relevant objectives from FS_QStream_MED that pertain to application scenarios, specifically:

• Objective #1: Identification of application scenarios and their delivery characteristics (uplink/downlink) for segmented media delivery services including:
• Low latency video streaming
• Live streaming
• On-demand platforms

• Short-form video platforms

• Objective #2: Identification of QUIC-based streaming technologies (DASH over HTTP/3, MoQ, MPEG-DASH over WebTransport, MPEG-DASH Part 6 over QUIC)

The document notes that each service/application may have different metric requirements, necessitating per-service/application analysis.

2. Proposed Application Scenario Template

The main technical contribution is a structured template with four mandatory sections:

2.1 Scenario Name

• Descriptive title for the application scenario
• References Clause 5.2.1 of TR 26.835 v0.0.1

2.2 Description

Comprehensive details including:
- Freeform text describing the use case
- Streaming-specific aspects:
- Delivery delay characteristics (Live, On-demand)
- Content source (Studio, User-Generated)
- Content characteristics (Low Bitrate, 4K)
- Justification for assumptions
- Underlying technologies overview
- QUIC relevance:
- How the scenario benefits from specific QUIC features
- Which QUIC-based protocol from Clause 4.2 of TR 26.835 applies
- Rationale for protocol selection
- Note: If protocol not listed in 4.2, contributors should first add it there

References Clause 5.2.1.1 of TR 26.835 v0.0.1

2.3 Application Scenario Requirements

Specific technical requirements including:
- Media formats
- Bitrate allocation
- Latency requirements
- Startup delay
- Other relevant parameters

References Clause 5.2.1.2 of TR 26.835 v0.0.1

2.4 Scenario Analysis

Testing and evaluation details:
- Test conditions preparation
- Proposed relevant metrics (cross-referenced to Clause 5.3 of TR 26.835 v0.0.1)
- Evaluation considerations
- Additional testing-related information

References Clause 5.2.1.3 of TR 26.835 v0.0.1

3. Integration Proposal

The document proposes incorporating Clause 4 (the template) as a new subclause in the FS_QStream_MED Work Plan, providing a standardized approach for all future application scenario contributions.

Document Purpose

This is a procedural contribution establishing a framework for future technical contributions rather than proposing specific technical solutions. It aims to ensure consistency and completeness when application scenarios are proposed for the QUIC-based streaming technologies study.
