LCEVC test streams

Description of various MPEG-5 LCEVC test streams available from V-Nova and other vendors, to validate a variety of integrations for different applications.

V-Nova test streams

As the lead developer of MPEG-5 LCEVC, V-Nova provides sample LCEVC streams to support customer evaluation, demonstrations and integration work. These are provided as-is and not as formal compliance streams set. They are intended to help customers get started and to support practical testing of playback or integration scenarios.

V-Nova test streams are divided into:

1. LCEVC test streams

   1. Contains streams combined with various base video codec such as AVC, HEVC, VVC combined with the LCEVC-enhancement carried in SEI or a separate track (in a single or separate streams) in practical carriage formats such as MP4 and Transport Stream, with DASH/HLS-style delivery variants

   2. Target users: media player vendors, app developers and platform teams

2. DTV+ test streams

   1. Contains streams with focus on the TV3.0 (DTV+) use case streams with VVC as base codec

   2. Target users: encoders, SOCs and media players working on Brazilian TV 3.0 (DTV+), TV2.5 terrestrial as well as broadcasters conducting receiver or device-related evaluations

3. DVP test streams

   1. Contains streams specifically designed for SOC driver-level integration of LCEVC using the DVP. DVP is a library for LCEVC Hybrid Driver-level Decoder product integration described here: https://docs.v-nova.com/technologies/mpeg-5.lcevc/decoder/ndk/lcevc-hybrid-driver-level-decoder

   2. Target users: TV and STB SoC vendors integrating the DVP decoder solution.

Please note that V-Nova sample streams are provided as-is and are not a formal compliance test suite.

Allegro compliance streams

Allegro DVT, a global leader in digital video compression solutions development, provides the following packages for elementary and system-level compliance:

1. Sirius elementary streams: MPEG-5 / LCEVC

   1. The test suite contains:

      1. Syntax streams, to ensure that the decoders support all LCEVC enhancement layer coding tools

      2. Performance streams, to test decoding speed (i.e. capability to decode worst case streams in real-time)

      3. Error resilience streams, to test decoders behaviour with non-compliant streams.

   2. Target users: IP and IC vendors, system vendors (set-top boxes, digital TVs, smartphones, tablets, etc.).

2. Streamwise system stream: TV3.0 (DTV+)

   1. Consists of carefully prepared video and audio test streams for self-testing against the relevant parts of the basic broadcast TV 3.0 (DTV+) specification.

   2. Target users: IC vendors, system vendors (set-top boxes, digital TVs, smartphones, tablets, etc.) and broadcasters.

MPEG/ISO LCEVC elementary streams

MPEG/ISO provides a set of LCEVC elementary bitstreams designed to verify whether bitstreams and decoders meet normative requirements specified in ISO/IEC 23094-2. These streams are provided as enhancement-layer-only streams with the base codec provided as YUV file.

These streams can be useful for early-stage experimentation or initial validation, particularly for teams that want access to basic LCEVC elementary streams. Please be aware these are a limited sample set rather than a comprehensive compliance suite provided by other commercial vendor.

The streams can be purchased from ISO here: https://www.iso.org/standard/80902.html#amendment
