Searching for "UCast v461" does not yield results for a specific software version with that exact number. However, primarily refers to two distinct technologies: uCast (Universal Conditions AST)

• The Publisher: Broadcasts frames continuously.
• The Subscriber: Monitors Sequence ID. If a gap is detected (e.g., receiving Seq 100 after Seq 98), the subscriber buffers the out-of-order packet and requests a retransmission of Seq 99.

The Headline Feature: Performance Polish

• Large-scale live events: Millions of viewers use a mix of edge relays and CDN-assisted network paths to lower origin bandwidth and cost.
• Enterprise collaboration: Internal meeting rooms and remote workers benefit from low-latency mesh relays within corporate network boundaries, with SD-WAN integration.
• Edge-enabled IoT streaming: Cameras and sensors offload video via local relays to reduce upstream bandwidth while preserving timeliness.
• Hybrid cloud-bursting: Media providers dynamically instantiate relay clusters in cloud regions to absorb spikes.
