Suporte a MPD Events em protótipo do Persistent Media Player da TV 3.0

Abstract

The consumption of audiovisual content is increasingly present in society. Mainly due to the advancement of data transmission technologies, such as the internet itself, traditional producers of this type of content also need to evolve. In this context, TV 3.0 standard was proposed, introducing a new way of interacting with and conceptualizing television, enabling new possibilities for viewer interaction with content. This work presents an evolution of the Persistent Media Player prototype, aiming to enable the native processing of Media Presentation Description (MPD) Events in compliance with the standard ABNT NBR 25608 (2025). The objective was to implement a mechanism for extracting, structuring, and distributing events present in DASH manifests for interactive applications. Experimental tests were conducted to measure event delivery latency under different resolutions and manifest loads. The results demonstrate that,

in scenarios with multiple simultaneous events, the observed latency tends to remain low, indicating the technical feasibility of the proposed implementation for live streaming environments. Therefore, the extension contributes to the TV 3.0 ecosystem by implementing a requirement established by the standard in a prototype applicable to interactive application development environments and compliance testing scenarios.
