1. INTRODUCTION

   In todays digital age, the way we consume media has drastically transformed, with streaming platforms becoming the cornerstone of modern entertainment. These platforms offer unparalleled convenience, allowing viewers to access an extensive array of content on-demand, from blockbuster films to niche documentaries. However, despite the vast selection and ease of access, one key element often missing from this experience is the shared joy of watching content together with friends and family. The communal experience that once revolved around gathering in living rooms to enjoy a movie or TV show has been diminished in this shift to solo streaming. Recognizing this gap, WatchHub was conceived as a platform dedicated to bringing people together, no matter where they are in the world, to experience the joy of synchronized viewing. It works on the concept of synchronized video playback, where users can watch content simultaneously in real-time while interacting with one another.

   Its simple and effective in creating virtual spaces where people could watch videos together, chat, and share moments in a synchronized environment. Building on this foundation, WatchHub offers a more personalized and enriched viewing

   experience. It allows users to create and customize their virtual rooms, choose from a diverse range of content sources, and integrate social media to share their viewing experiences with a broader audience.

2. PROBLEM STATEMENT

   To address the growing disconnect in media consumption caused by the rise of on-demand streaming services, which primarily cater to individual viewing experiences, there is a pressing need for a solution that restores the communal aspect of watching content together. The shift towards solo streaming has led to a decline in shared viewing experiences, where real- time reactions, discussions, and emotional connections are often lost. Despite the convenience and variety offered by these platforms, they do not provide a way for users to enjoy content collectively, regardless of their physical location. WatchHub seeks to bridge this gap by enabling users to watch and engage with media content simultaneously, fostering a sense of togetherness and community in the digital age. By offering features such as synchronized playback, interactive chat, and customizable viewing rooms, replicates the shared viewing experience but also enhances it, making it more adaptable to modern digital lifestyles. This platform responds to the evolving needs of users who crave connection and shared experiences in a time where physical distance is often a barrier.

3. OBJECTIVES OF THE STUDY

   • To analyze the current limitations of existing co-viewing platforms in terms of synchronization accuracy and user interaction.

   • To design and implement WatchHub with real-time video synchronization and integrated communication features.

   • To assess the user experience and performance of WatchHub across different network and device platforms. conditions

   • To explore the potential use of WatchHub in diverse settings such as virtual classrooms, team-building exercises, and social events.

4. LITERATURE REVIEW

   1. The research paper titled "DiVAS: Video and Audio Synchronization with Dynamic Frame Rates" was authored by Clara Fernandez Labrodor Mertcan akc Eitan and published in 2020. This paper introduces DiVAS, a system designed for synchronizing video and audio streams dynamically by adjusting frame rates in real-time. The study focuses on the challenges of maintaining synchronization across different network conditions and varying device capabilities. By implementing dynamic frame rate adjustments, DiVAS addresses the issue of desynchronized playback in distributed environments. The empirical analysis and experimentation in the paper demonstrate the system's effectiveness in providing a smooth and synchronized multimedia experience, even in scenarios with fluctuating network quality [1].

   2. The research paper titled "Are we in Sync? Synchronization Requirements for Watching Online Video Together" was authored by David Geerts, Ishan Vaishnavi, Rufael Mekuria, Oskar van Deventer, and Pablo Cesar. It was published in 2011. This paper examines synchronization requirements for providing remote shared experiences while watching online videos together, a growing trend in social video applications. The study focuses on how synchronization differences between users' video streams impact the sense of togetherness and annoyance, comparing experiences using voice chat versus text chat. It suggests that synchronization delays above 2 seconds become noticeable in voice chat, while a delay of up to 1 second is acceptable for a seamless shared experience [2].

   3. The research paper titled "Collaborative Online Learning with VR Video: Roles of Collaborative Tools and Shared Video Control" was authored by Qiao Jin, Yu Liu, Ruixuan Sun, Chen Chen, Puqi Zhou, Bo Han, Feng Qian, and Svetlana Yarosh and published in 2023. This paper investigates the use of collaborative tools and shared video control in virtual reality (VR) to enhance online learning experiences. The study focuses on the comparison of three distinct VR video viewing modes: Basic mode, which represents traditional individual video control, Non-Sync mode, which provides individual control but includes collaborative tools, and Syc mode, where users share control of the video playback 4 [3].

   4. The research paper titled "Real-Time Video Conferencing Application" was authored by Suchitra Deokate, Shrija Dange, and Preeti Shriwastav, and published in the International Journal of Creative Research Thoughts in November 2022. This paper presents a design and implementation of an open source video conferencing prototype. The system is designed to allow seamless real-time video and audio communication across different locations, especially in light of the increased demand due to the global COVID-19 pandemic. The study highlights the technological advancements in video conferencing, such as improved video compression and the ability to function on standard broadband connections and network infrastructure [4].

   5. The research paper titled "Video Conferencing WebApp" was authored by Sanjay Majhi, Naman Ahuja, and Sudha Narang and published in December 2021. This paper discusses the development of a real time video conferencing application using WebRTC and socket programming, focusing on providing features like group video chats, real-time messaging, and screen sharing. The system architecture is built using a combination of technologies, including Node.js

   and Express.js. The empirical analysis demonstrated the application's effectiveness in providing real-time communication and data sharing, making it suitable for business, education, and healthcare [5].
