Sirius AV2 Elementary Streams are compliance bitstreams developed by Allegro DVT to thoroughly validate AV2 Decoder implementations against the full breadth of the codec specification.

AV2, the next-generation video compression standard developed by the Alliance for Open Media, delivers a substantial leap in coding efficiency over its predecessors. It introduces native support for AR/VR content, improved handling of modern display formats, and a wide range of enhancements designed to meet the demands of today’s high-quality media experiences.

Unique selling points
Avoids expensive re-design phases and shortens development cycles. Due to their high complexity, video decoders need to be extensively validated ahead of production.
Strengthens the decoder against all encoding features, existing or to come, to extend final products’ life.
Customers
IP and IC vendors, system vendors (data centre SoCs, AI SoCs, security cameras, drones, set-top boxes, digital TVs, smartphones, tablets, etc.).
Deliverables
Elementary streams suite, each stream focusing on a specific video feature to allow fast and simple analysis of potential issues.
Complete reference documentation.
Technical Features

Syntax streams ensure that Decoders support all coding tools.

Performance streams test Decoding speed (i.e. capability to Decode worst case streams in real-time).

Error resilience streams test Decoders’ behaviour with non- compliant streams.
