Media Centre

Media Centre

GSI was brought into the Sony Pictures Television, Media Centre project late in 2013 to augment the existing team. Media Centre manages the digital media supply chain where it ingests and delivers core media files to broadcasting centers and catch-up operators across Europe and soon to be worldwide. While working with project stakeholders, we delivered over 350 individual comps with supporting documentation and spent 11 months as the product design and application development leader for the project.



GSI is the primary development and product partner in a new offering from Sony DADC that completes the story of their vast systems and services offering. Venue allows content owners and aggregators to launch a one-stop shop OTT platform backed by their industry leading digital supply chain solutions. The Venue offering provides a compelling and unique experience unlike anything available on the market today.



Sony Pictures Entertainment and GSI recently concluded design and product planning for Project Blueprint. Similar to Media Centre in our deliverables, GSI prepared a proof of concept by creating hundreds of mockups of screens that illustrate core functionality of the final proposed product. We work directly with internal stakeholders in a business analyst capacity to gather requirements and make sure our proposed solutions are on target for the audience.



GSI works with Sony DADC as a leader of external facing product and technology. We have designed, developed and implemented a suite of solutions that allow their internal systems to be accessible as a compelling SaaS platform called Molecule. Core to the offering is a best-in-class metadata management utility allowing multiple inputs and multiple to-spec outputs that allow Molecule to interface with any and all distribution companies worldwide. Molecule is an end-to-end digital supply chain offering that powers some of the largest entertainment companies in the world.



GSI was hired by Rightsline, an industry leading digital rights management platform, to augment their UI team, providing creative and functional direction to the upcoming Rightsline SaaS release. GSI worked closely with internal stakeholders to design a complete set of functional mocks and accompanied style guides to be used in the new product release.



Sony Pictures contracted GSI to design and build ODIN, a multi-sourced metadata brokering and publishing system. Included in our work was design, development, deployment and managing the successful hand-off of the application to internal Sony developers. ODIN is responsible for aggregating and disseminating metadata across all upstream and downstream systems across Sony Pictures. We continue to be involved in ongoing product planning, design and UI implementation.
