Distributed Media Stream Transcoding for Heterogeneous Devices

The patent applies self-service by enabling viewer hosts to perform transcoding operations themselves. Instead of relying on a dedicated transcoding server, the system allows any viewer with sufficient computing resources to act as a transcoder for other viewers. This distributes the transcoding workload across the network participants, eliminating the need for centralized transcoding infrastructure while maintaining adaptability to heterogeneous devices.

The patent uses an intermediary approach by introducing a distributed network of viewer hosts as intermediaries between the sender and end viewers. These intermediary hosts receive the original media stream, transcode it to appropriate quality levels, and deliver it to viewers with matching capabilities. This distributed intermediary system replaces the traditional centralized transcoding server while maintaining the necessary adaptation functionality.

The patent applies segmentation by dividing the transcoding task into separate operations performed by different hosts in the network. Instead of the sender generating all media streams, the workload is segmented and distributed to various viewer hosts that have available computing resources. Each segmented transcoding operation is performed independently by different hosts, reducing the burden on the original sender.

The patent introduces a new dimension to the media streaming architecture by adding a distributed transcoding layer across multiple network hosts. This dimensional expansion transforms the single-point transcoding model into a multi-point distributed model, allowing transcoding operations to occur at various locations in the network rather than being constrained to the sender's resources.

The patent applies self-service by enabling distributed hosts to perform transcoding operations locally without requiring centralized server intervention. This eliminates the trust issue associated with centralized servers that must decrypt and re-encrypt media streams, as each host independently processes the encrypted stream using its own computing resources, maintaining end-to-end encryption throughout the process.

The patent uses distributed viewer hosts as intermediaries that operate within the encrypted communication channel. These intermediary hosts can perform transcoding on encrypted streams without needing to decrypt them, maintaining security while enabling adaptation. This distributed intermediary approach replaces the trusted centralized server model with a trustless distributed model where no single party needs to compromise security.
