Integrated broadcast-broadband (IBB) systems have been standardized for device collaboration between broadcast and broadband contents as well as between TVs and diverse devices such as Internet of Things or smart devices. However, in existing IBB standards, TVs are typically identified as the primary devices (i.e., servers), and the other devices are identified as the companion devices (i.e., clients), which makes communication between two TVs impossible. To this end, we propose a common receiver architecture as a distributed IBB system that realizes local device cooperation with equal roles (client and server, i.e., "servient"). As an equal-role device collaboration for presenting content, this study focuses on the use case of switching devices while playing the same content. The proposed architecture acts as middleware to realize local device communication between TVs and other devices using web-based communication, such as hypertext transfer protocol. Device-independent cooperation is achieved using our developed prototype for TVs and smartphones, and the prototype is verified via thorough user testing with significantly satisfactory feedback.

“…In other words, performance and other features are verified within a scope unrelated to transmission channel abstraction. Media-unifying platforms [14] can be used for abstracting transmission channels when use cases are realized as an overall service.…”
