Sony Patents a Server That Adjusts Data Formats When Network Quality Drops

By Patentlyze Team · Updated Jul 10, 2026

Most apps treat your network connection as a single pipe. Sony's new patent describes a server that watches each type of data it sends individually and reshapes that data when the connection starts struggling.

How Sony's per-flow quality monitor actually works

Imagine you're in a video call that also shares your location and some sensor readings in the background. Your phone is sending several different kinds of data at once, but from the network's perspective, they all travel together as if they're the same thing. If the connection gets choppy, everything suffers equally, even the parts that could tolerate a lower quality signal.

Sony's patent describes a server that breaks that assumption. It assigns each type of data its own dedicated quality-of-service lane on a single network session, then watches how each lane is actually performing. If one lane falls below an acceptable threshold, the server automatically changes how that data is packaged or formatted to better fit the current conditions.

The practical idea is that a video stream, a control signal, and a sensor feed all have different tolerances. This system lets a server treat them differently in real time, squeezing more useful performance out of a connection that can't fully deliver on all fronts at once.

How the server maps data flows and triggers format changes

The patent describes an application server that manages multiple QoS flows (quality-of-service flows, meaning individually prioritized data lanes) within a single PDU session (a protocol data unit session, which is the standard container 5G networks use to carry data between a device and the internet).

The server's processing unit runs through several steps:

• It decides which pieces of data will travel over a single PDU session.
• It determines how many separate QoS flows to create within that session, what characteristics each flow should have (such as priority level or bandwidth), and how each flow should be monitored.
• It sends a request to the core network to set up those flows with those specific parameters.
• It maps each data type to its own dedicated flow.
• It receives live monitoring reports back from the network about how each flow is actually performing.
• If any flow's measured performance falls short of the target, it modifies the format of the data on that flow, for example compressing a video stream or reducing sensor resolution, to bring it back within acceptable bounds.

The monitoring and format-adjustment steps are the key addition here. Standard QoS setups can prioritize traffic, but this system closes the loop by acting on real measurements rather than just hoping the priority settings are enough.

What this means for apps sending mixed data over 5G

This kind of per-flow, feedback-driven control matters most for applications that mix data types with very different tolerances, think augmented reality, remote robotics, connected vehicles, or real-time collaborative tools. In those contexts, letting one struggling data type drag down everything else is a real problem, and today's systems don't have a clean way to isolate and compensate for just that one type.

For Sony specifically, the patent fits naturally with its interests in gaming (PlayStation Remote Play, for instance, mixes video, audio, and control inputs), professional streaming hardware, and industrial IoT. The filing targets 5G infrastructure, so any benefit would flow through the network layer rather than requiring changes to your device.
