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: 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. To request V-Nova Sample Streams please reach out [**support@v-nova.com**](mailto:support@v-nova.com) our team will manage the streams package access through V-Nova Download Portal . ## 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. More information on how to purchase can be found from Allegro:
## 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: --- # Agent Instructions This documentation is published with GitBook.
