To add to the fun, we decided to create a streamed game experience using Forza Horizon 5 from an Xbox Series X as our source. To test the Talon, we needed a high-quality 4K 60fps stream. Testing the Osprey Talon Encoder with 4K 60fps Video With the enterprise feature set, the encoder allows customized consent banners, HTTPS administration security, an OpenVPN client, and a firewall to block access to the management IP. The Talon user interface exposes advanced codec settings, such as the min and max QP settings, so that the stream can be optimized based on the content. From the dashboard screen you can see a thumbnail of the input, information about the thermal performance of the unit, as well as the ability to start and stop the stream. It provides quick access to the configuration of the encoder as well as the configuration of its output. Unfortunately, H.265 is not going to be a viable codec for use with WebRTC, so we will continue to focus on H.264 until more client device hardware supports AV1.Ī web interface is provided to configure the Talon encoder. In addition to supporting H.264, the Osprey units also support H.265. ![]() ![]() The units themselves are essentially heat sinks, allowing the Talon to operate without a fan and the accompanying noise. Embedded 708 captions are supported, as well as the ability to send KLV metadata. The Osprey unit supports AAC and OPUS audio in both 44.1 and 48KHz sample rates. For recording purposes, the Talon can also save to an MP4 while delivering a stream. Output transports include RTMP(S), MPEG-TS uni and multicast over UDP, RTP, Zixi, SRT, and WHIP. This allows the Talon to encode up to 4K 60fps in 10-bit HDR (4:2:2) video. Via this chip, Osprey was able to attain its goal of achieving the lowest latency while not sacrificing quality. The Talon encoder comes in two form factors, one including 12G-SDI in/out and HDMI and another with a single 12G-SDI in. It features the AMD Xilinx Ultrascale+ Architecture at its core, giving the unit the ability to stream 4K at 60fps. The first problem when heading into this realm is how to generate a 4K stream to send to your ingest. There are newer codecs to help with this, but, until more devices support AV1 hardware acceleration or the industry fully supports H.265 for WebRTC, we are stuck streaming with older protocols like H.264. And then you have to double that rate once more to stream at 60 frames per second. In order to get that amazing 4K picture, you need to deliver four times as many bits to the screen as with 1080p. Red5 Pro also has the need for interactive real-time latencies, adding further computational complications. Just as the broadcast industry had to go through major upgrades to support 4K, the streaming industry does as well. ![]() If 4K is the standard in broadcast, you might be wondering why it’s so challenging to stream. We’re happy to say that those issues are in the rearview mirror as Red5 Pro delivers the gold standard in 4K using the Osprey Talon encoder. As with all bleeding edges, this one was fraught with issues to be resolved. But real-time interactive streaming (RTIS) video at 60 frames per second(fps) in 4K resolution is certainly on the bleeding edge. It is widely accepted that 4K resolution is the current standard in the broadcast media industry.
