SMPTE RDD 40 – Essence-independent IP Live Networked Media Transport

Introduction

Although network systems have become common in file-based applications, until recently it has been difficult to apply networking technologies to live production applications in which there is a strong requirement for real-time processing.

However, with the continuing rapid evolution of networking technologies, there is now a trend towards the use of networked systems for live production applications.

This RDD describes an IP-based transport mechanism (referred to hereafter as `IP mapping’) intended mainly for live production applications.

1 Scope

This RDD defines the IP mapping which includes the following main characteristics:

1. Essence-independent mapping

Each essence (video, audio and ancillary data) can be dealt with independently.

2. Packet protection using FEC and/or hitless failover

Appropriate protection can be chosen according to application requirements.

3. Frame-boundary-aware mapping for both essence and FEC

Frame accurate processing can be performed in both essence and FEC.

4. Support for up to 4K uncompressed and compressed video

Either uncompressed video or compressed video can be chosen up to 4K video seamlessly according toapplication requirements.
