Development of a Low-End Device-Compatible Smart TV Streaming Application

The client faces difficulties in supporting low-end Smart TVs, including outdated operating systems and hardware limitations, leading to playback issues, insecure scripting practices, and maintenance challenges that hinder broad device compatibility and user experience accessibility.

A mid-sized media and entertainment company aiming to expand its digital content access to budget-friendly Smart TV users via adaptable streaming apps.

• Create a streaming app that supports legacy and current versions of Smart TV platforms such as Tizen and WebOS.
• Ensure compatibility with older hardware models, including devices with outdated Chromium browsers, by optimizing streaming, DRM, and UI performance.
• Reduce ongoing maintenance costs through code modularization and support for multiple device generations.
• Achieve smooth playback and responsive UI on low-end devices by minimizing resource-intensive features such as complex animations.
• Convert web-hosted apps into packaged formats compliant with platform app store requirements to enable official submissions and updates.
• Implement robust testing procedures across various devices, browsers, and OS versions to ensure consistent functionality.

• Support for legacy (older Chromium, Tizen 2.3, WebOS 3.5) and current (Chromium 69+, WebOS 68+) platforms through separate app versions.
• Conversion of web-hosted applications into packaged apps for app store approval and distribution.
• Flexible streaming configuration supporting various DRM systems, with a focus on Widevine for broader compatibility.
• UI optimization including minimized CSS and JavaScript animations, usage of Canvas for rendering, and lazy loading techniques.
• Elimination of inline scripts, replacing with external JavaScript files to comply with Content Security Policies.
• Comprehensive cross-device and cross-platform testing utilizing developer tools for debugging and quality assurance.
• Bug triage and prompt fixing prioritized by severity to ensure quality standards.

• Streaming servers configured for DASH streaming with DRM support.
• DRM services supporting Widevine and other systems as needed.
• Platform-specific app store submission processes (e.g., Samsung Tizen, LG WebOS).

• Support for devices with Chromium versions as old as 4763 (legacy) and as new as 69+ (modern).
• Optimized performance to ensure smooth playback and UI responsiveness on devices with limited RAM and processing power.
• Adherence to security policies, including removal of inline scripts and external storage of scripts.
• Minimized load times via lazy loading and efficient rendering techniques.
• High reliability with thorough cross-device testing covering multiple hardware and OS versions.

The new application is expected to streamline development and maintenance processes by supporting multiple device generations with a single codebase, leading to reduced costs and faster deployment cycles. Supporting legacy devices will expand the user base, especially among those with older or lower-performance Smart TVs, thereby increasing overall app accessibility and market reach. The precise targeting of performance optimizations will ensure smooth playback and an improved user experience across all supported devices.
