# 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.
