AV1 compatibility: Migration strategies and Ales Player apps for Smart TVs
AV1 compatibility guide: benefits of AV1 and other new codecs, which TVs support them, compatibility checks in Ales Player and safe fallback/ABR implementations.
Introduction
Today, the adoption of new generation codecs (AV1, VVC/H.266, etc.) offers significant opportunities in terms of cost and user experience for both broadcasters and players. In this article, you will find how to test and gradually introduce new codecs, especially AV1, on smart TVs, compatibility checks, ABR/fallback strategies and concrete steps that can be implemented in Ales Player.
Why focus on AV1 now?
- Bandwidth savings: Real-world studies show that AV1 can deliver similar visual quality with typically 20–40% lower bitrate than HEVC. This provides cost and CDN savings, especially in 4K and HDR deployments.
- Open source and licensing structure: AV1 offers a more advantageous way in terms of licensing; however, application and hardware support expands over time.
- Long-term investment: Hardware acceleration (SoC supports) are expanding rapidly in new devices, so early planning pays off.
Codings and compatibility: quick comparison
| Codec | Typical bitrate gain (compared to HEVC) | Hardware acceleration status (2024–2026 general) | Application area |
|---|---|---|---|
| AVC/H.264 | Base, reference | On almost all devices | SD/HD broadcasts, backwards compatible |
| HEVC/H.265 | — | Widely supported | 4K HDR prevalence, VOD |
| AV1 | Save 20–40% | Accelerates on new devices; Requires software on older devices | 4K/8K optimization, tape cost reduction |
| VVC/H.266 | Potential 30%+ | Very limited, new | Promising high-yield scenarios |
Note: Percentages vary depending on content and encoder; Testing it on your own content set is a must.

Practical compatibility steps for Ales Player
- Collect user device information (SoC, OS version, model) at application launch. With this information, determine ABR and codec preferences on the content server.
- Automatic profile assignment using Ales Player's built-in "user-agent" and device metadata. For this step, take advantage of the Powerful Player features.
- Source preparation: multi-codec chain
- Prepare contents with at least two codecs (AV1 + HEVC or AV1 + AVC) including AV1, HEVC and AVC. This provides instant fallback on older devices.
- Serve manifests (HLS/DASH) with multiple representation on the CDN/packager side; Make sure codec and profile labels are clear for each representation.
- Player side: preference and fallback logic
- Let the player try AV1 first by looking at the device support table; If there is no support, switch to HEVC/AVC.
- In Ales Player, this logic can be managed with Multi-Source Support: multiple sources are defined for a channel/content and the player chooses the most suitable one.
- In case of error (frame drop, high CPU), auto-fallback should be activated; Protecting the user experience is a priority.
- ABR (Adaptive Bitrate) and bitrate ladder recommendations
- If you are using AV1, redesign your ABR ladder with about 25–30% lower bitrates; example ladder (for 4K60 HDR): 18 Mbps (AV1) / 12 Mbps / 8 Mbps / 5 Mbps / 2.5 Mbps.
- For 1080p: Aim for 4–8 Mbps RANGE instead of 6–10 Mbps.
- Always refine the ladder with monitoring data (QoE); Do A/B tests.
- Performance monitoring and quality control
- Collect frame-per-minute, re-buffer, CPU usage and image quality (SSIM/PSNR) metrics.
- Test sets: compare AV1 and HEVC encodes with different scenes (high motion, low light, fine detail).
Step-by-step migration plan for application and publisher operation
- Specify the target device group (new models + X% most used devices).
- Set your encoder and packager pipeline to produce AV1 output.
- Pilot (2–4 months)
- Start AV1 streaming for certain types of content (e.g. VOD premium 4K movies); Force on a small percentage of users.
- Intensively monitor telemetry: CPU, rebuffer, user satisfaction.
- Gradual roll-out (4–12 months)
- Expand AV1 representatives after successful pilot; In live broadcasts, try it first in streams that do not require low latency.
- Maintain HEVC/AVC fallback policy for older devices.
- Full transition (12+ months)
- If hardware support is above critical mass, default to AV1; 90%+ support of core devices should be targeted.
Warnings and practical notes
- Software decode CPU cost: Software decode, especially 4K60 AV1, can make playback unsustainable on low-power devices. That's why hardware detection and automatic fallback are essential.
- DRM compatibility: Verify DRM providers and license servers' compatibility with AV1 in advance; DRM integration may vary by platform.
- HDR and color management: Test for metadata accuracy and compatibility with the TV when using HDR (PQ/HLG) with AV1.
Quick checklist specific to Ales Player
- Device detection: Is SoC and OS information collected? (yes/even auto-tagging)
- Player fallback: Is there automatic switch to HEVC/AVC if AV1 fails? (will prevent user interruption)
- Multiple source management: Can multiple manifests be defined for the same content? Multi-source Support helps with this.
- Platform support: Test AV1 separately on Android TV App and Windows App.
Conclusion and recommendations
In summary, AV1 and similar new codecs offer serious advantages in terms of broadcast costs and band usage per user. However, the smart TV ecosystem is heterogeneous; Therefore, a gradual, data-driven and fallback transition strategy is essential. A risk-free transition can be achieved by using device discovery, automatic fallback and multi-resource management mechanisms on the Ales Player side (e.g. Powerful Player and Multi-source Support).
Practical advice (short):
- Today: check the AV1 decode capability of the 20 most popular models in your device fleet.
- 1–3 months: Start a small VOD pilot with AV1; Focus on telemetry.
- 3–12 months: Optimize your ABR ladder for AV1 and configure CDN packaging to support multi-codec.
For broadcasters using Ales Player: Testing player settings and multiple manifests when migrating to AV1 minimizes user disruption and allows you to safely achieve cost advantage. Additionally, tagging users during pilot processes and implementing gradual expansion is the key to a successful transition.
FAQ
Q: Which TV models does AV1 work on? A: Most next-generation TV and streaming-box manufacturers (e.g. last-generation Android TV set-top boxes and some newer SoCs) support AV1 hardware acceleration. The safest way is to check the model manufacturer dump and SoC specification.
Q: What is the biggest risk in switching to AV1? A: The biggest risk is high CPU usage and playback errors on user devices as a result of switching to AV1 broadcast without adequate hardware support. That's why automatic fallback is important.
Q: Is there HDR compatibility with AV1? A: Yes, AV1 can carry HDR; however, HDR metadata and tone-mapping compatibility varies from device to device. Confirmation with test kits is essential.
Q: How do I test AV1 support in Ales Player? A: First, run AV1 playback tests on target devices. Collect frame-drop, CPU and rebuffer metrics by activating device reporting through Ales Player; Test automatic fallback scenarios.
Q: How much does AV1 reduce CDN cost? A: It depends on the content; Tape savings of 20–40% can be targeted for typical 4K content. It's hard to give an exact number without measuring on your own content set.
Q: Is AV1 mandatory on all platforms? A: No. The transition should be gradual; HEVC/AVC fallback should be preserved on older platforms. This preserves the user experience and reduces the risk of migration.
