Multimedia devices have played an important role in making OTT a success story and a viable commercial service. HSC has expertise and experience in working on multimedia devices, right from applications to OTT middleware to lower-level software like device drivers.
HSC’s experience, which spans across mobile devices, smart TVs, set-top boxes, home gateways, gaming devices etc., is described in the illustration:
Application engineering and UI Layer is the most dynamic part of the OTT client because of ongoing advancements and changes in underlying platforms and operating systems.
HSC has rich experience in
Two Application models are prevalent here:
HSC has developed HTML/5-based applications for PC, Mac, and Windows-based platforms like Xbox.
Adaptive streaming algorithms, streaming protocols (HTTP, HLS, HDS, RTSP), DRM, Concurrency Management, State Machines and Metadata Handling for On-Demand and Live-streams form core part of an OTT client.
HSC has extensive experience in these areas, including experience in some advanced features like integration with 3rd party analytics engines (like Nielsen) and Dynamic Ad Insertion.
Video rendering is another area which is mostly platform dependent and needs efficient integration with platform-specific rendering mechanisms and APIs.
HSC has good experience in integrating third-party HLS players, custom rendering APIs and frame-based rendering frameworks like OpenGL, GDI+ and Gstreamer. Efficient integration with platform rendering mechanism is important to maintain an accurate video clock and smooth viewing experience.
HSC has good experience in writing low-level software in area of network protocols, file systems and Audio & Video streaming device drivers.
HSC is an active member of the RDK consortium which defines reference architecture and stack for software on CPEs like set-top boxes, gateways, and converged devices. RDK also provides a pre-integrated software bundle that provides a common framework for accelerated solutions development of OTT applications.
HSC possesses rich experience in many open-source components which are part of RDK bundle and has worked towards developing PoC of OTT apps based on RDK.
The figure below illustrates HSC expertise and focus areas on RDK components:
