As communities rely on technology for information dissemination, Barangays must keep pace. Training Barangay officials, a key source of local information, enhances their ability to promote and communicate efficiently. The project offered capability training in Records Management, Basic Computer Maintenance, and Multimedia Technology. Objectives included the following: providing knowledge on ICT, streamlining document processes, introducing multimedia tools, conducting hands-on training, and evaluating outputs. A framework was adapted to guide the project, from needs assessment to implementation. The training averaged a 4.64 rating, indicating success. This model supports digital literacy for marginalized sectors and can be replicated in other municipalities for greater impact....
Multimedia Forensics (MMF) investigates techniques to automatically assess the integrity of multimedia content, e.g., images, videos, or audio clips. Data-driven methodologies like Neural Networks (NNs) represent the state of the art in the field. Despite their efficacy, NNs are often considered “black boxes” due to their lack of transparency, which limits their usage in critical applications. In this work, we assess the interpretability properties of Deep High-Frequency Residuals (DHFRs), i.e., noise residuals extracted from images by NNs for forensic purposes, that nowadays represent a powerful tool for image splicing localization. Our research demonstrates that DHFRs not only serve as a visual aid in identifying manipulated regions in the image but also reveal the nature of the editing techniques applied to tamper with the sample under analysis. Through extensive experimentation on spliced amplitude Synthetic Aperture Radar (SAR) images, we establish a correlation between the appearance of the DHFRs in the tampered-with zones and their high-frequency energy content. Our findings suggest that, despite the deep learning nature of DHFRs, they possess significant interpretability properties, encouraging further exploration in other forensic applications....
Bangladesh witnessed its biggest nationwide mass uprising since gaining independence in 1971, which led to the overthrow of an authoritarian government that had existed for a decade. This study employed the protest paradigm to analyze how the protests were framed by mainstream print media and how media ownership influenced their coverage. Drawing on a quantitative content analysis of five major newspapers from different ownerships, the study explores dominant media frames, tone, and legitimacy of protest coverage. The findings indicate that media ownership significantly affects the credibility and tone of the protest coverage. The protest paradigm was applied more strictly by pro-government media outlets. Independent and anti-government outlets, on the other hand, took a more impartial stance. The study reveals how media ownership shaped the framing of dissent, reinforcing the protest paradigm in ways that aligned with the ruling party’s interests. This study adds to the body of knowledge on South Asian media bias and authoritarian information control....
RTK 2 is an unordinary example that helps unravel the complex process of establishing, operations, and the role of minority-language media within public service broadcasters in transitional societies that have a legacy of war. As a Serbian-language television channel within the Radio Television of Kosovo, RTK 2 also provides an opportunity to analyze media outlets that were established as part of conditions imposed by foreign political decision-makers in countries where the largest minority is subject to the dual influence of both the official majority’s politics and that of the kin-state. Through an analysis of legal documents and an analysis of the news discourse, this study addresses two key aspects: the practical implementation of the concept of a public television channel for the largest ethnic minority within a multiethnic PSB at the managerial and news content level. The analysis confirms that RTK 2 attempts to maintain a balance between rival political factors influencing it, but this has a negative impact on the quality of its news content. This study contributes to the field by presenting a unique but under-researched case that can inform future comparative research on minority programs within the framework of public service broadcasting in multiethnic environments. The findings provide lessons learned from the operational practices of programs essential to the concept of multiethnic societies, yet shaped and constrained by political conditions....
Illegal broadcasting is one of the primary challenges for Over the Top (OTT) service providers. Watermarking is a method used to trace illegal redistribution of video content. However, watermarking introduces processing overhead due to the embedding of unique patterns into the video content, which results in additional latency. End-to-end network latency, caused by network congestion or heavy load on the origin server, can slow data transmission, impacting the time it takes for the segment to reach the client. This paper addresses 5xx errors (e.g., 503, 504) at the Content Delivery Network (CDN) in real-world video streaming platforms, which can negatively impact Quality of Experience (QoE), particularly when watermarking techniques are employed. To address the performance issues caused by the integration of watermarking technology, we enhanced the system architecture by introducing and optimizing a shield cache in front of the packager at the origin server and fine-tuning the CDN configuration. These optimizations significantly reduced the processing load on the packager, minimized latency, and improved overall content delivery. As a result, we achieved a 6% improvement in the Key Performance Indicator (KPI), reflecting enhanced system stability and video quality....
