    paper Development of a system to insert subtitles into an existing transport-stream

    The task was to take an existing MPEG-2 transport stream, and merge in DVB-TXT subtitles live, using subtitles delivered over EBU-TT live (using a websocket)

    I designed and implemented, using some existing building blocks where possible, a program to read the input transport stream and create a low-resolution, low-latency preview to be sent to subtitlers. The subtitles were then received via a websocket in EBU-TT format (XML) and encoded as DVB-TXT, then merged into the existing stream.

    The DVB-TXT encoder was written in Rust, since it requires a lot of data manipulation, and therefore is ideal for Rust’s safety guarantees.

    The preview stream was generated using FFMpeg for encoding, and Nablet’s MPEG-2 muxer for mulitplexing. We considered using WebRTC for this, however the customer decided it was too hard to deploy for their network.

    paper Android Device Farm Management
    • Led further development of an Android ad-harvesting platform, with a strong focus on reliability, robustness, and defect resolution.
    • Advised on and executed device farm upgrades, including building and deploying a patched Android OS to meet project requirements.
    • Rebuilt and standardised backend servers controlling the device fleet using Ansible, dramatically improving consistency, repeatability, and maintainability.
    • Introduced infrastructure-as-code practices, providing living documentation of system configuration and reducing operational risk.
