S4C Case Study

The Brief

The brief for S4C included some specific features which have not yet been deployed on YouView such as dual language, multiple subtitles and dual audio. LoungeLogic worked closely with YouView and S4C to pre-empt any issues and to ensure they did not create any obstacles in the on-boarding process.

The Process

The UI was to be created in-house. Our developers worked closely with S4C designers to establish what was technically possible on the platforms and to ensure the UX satisfied YouView requirements. Both teams kept in close contact, creating several prototype designs which were trailed and presented to S4C management before the final clean crisp design was agreed upon.

We found Lounge Logic very easy to work with during the on boarding process for S4C’s on demand player – which was added to both our on demand TV players page and incorporated into our seven day scroll back programme guide. The process involved a number of stakeholders and the development of a number of complex ‘feature-firsts’ for the platform which Lounge Logic took in its stride by working through everything, including last minute changes, quickly and efficiently.

S4C Grab

Once the high level design was signed off, there was an intense period of development to incorporate all the low level requirements, with several increments with the designer to maintain a integrated approach.


User and acceptance testing was complimented by STBT testing. Lounge Logic created STBT tests for the majority of YouViews required acceptance tests.

This multi-faceted approach to testing allowed the S4C application to rocket through YouView's player acceptance tests, saving time and cost.

We chose LoungeLogic to work with S4C’s in-house development and creative team in order to create the application and to allow S4C to onboard the YouView platform after submitting a very impressive tender. LoungeLogic delivered the vision from the S4C creative team whilst also delivering a very responsive application, the project was delivered on time and on budget under a very tight deadline.
It was a joy to work with such a flexible team who went the extra mile in order to deliver S4C’s vision for the application

Extending our Roku offering to Scene Graph.


In February, Roku announced the deprecation of their legacy SDK visual screen components, with a two-year roadmap for adopting a channel UI built in Roku SceneGraph. The developers at Lounge Logic have also been busy, ensuring we have the knowledge and tools in place to build these new apps. We have now extended our Roku codebase to include Scene Graph based utilities and components in line with our Javascript OTT offering. Scene Graph is maturing fast but is not without its pitfalls. Apps need to make careful use of each thread or risk execution timeouts. We have put in place an architectue which makes as much use of the multi-threading as possible but still allows us freedom to create a very robust app with a fully bespoke UI.
