Frequently Asked Questions

OTT describes internet-delivered video as a broader category. SVOD is one specific OTT monetization model based on recurring subscriptions.

Yes. Movies can use multi-window distribution, moving from theatrical release to premium digital services and eventually subscription or ad-supported streaming, depending on rights and strategy.

SVOD is changing movie distribution and viewing behavior, but it does not eliminate the unique value of theatrical exhibition. Many movies can use both theatrical and streaming windows.

A Multi-CDN strategy uses two or more Content Delivery Networks to distribute streaming traffic intelligently. This improves performance, increases reliability, and reduces the impact of outages or network congestion.

Yes. Intelligent routing directs viewers to the CDN delivering the best performance at that moment, reducing latency and minimizing buffering.

While it offers the greatest value for enterprise platforms with global audiences, growing OTT businesses can also benefit as they expand into new regions or experience higher traffic volumes.

Traffic management systems continuously monitor CDN health. If one provider experiences degraded performance or an outage, requests are automatically redirected to another healthy CDN with minimal impact on viewers.

It can introduce additional operational complexity, but intelligent routing often optimizes bandwidth usage, improves efficiency, and reduces the business impact of downtime, making it a worthwhile investment for many enterprise platforms.

Vodlix provides a scalable OTT platform with enterprise-grade capabilities including global content delivery, adaptive streaming, DRM protection, analytics, live streaming support, Smart TV applications, and infrastructure designed to deliver reliable streaming experiences worldwide.

It is the practice of building a streaming service that works across many devices and platforms, from smartphones to smart TVs, with a consistent, high-quality user experience on each.

Viewers now expect seamless access to their content on whatever device they choose, anytime and anywhere. A multi-platform strategy drives engagement and satisfaction and is essential to stay competitive.

Content must be optimized for varying screen sizes, resolutions, and aspect ratios using responsive design, adaptive streaming, and intelligent transcoding to preserve visual and audio quality on every device.

Adaptive bitrate streaming automatically adjusts video quality to each viewer's internet connection, preventing buffering on slow networks while delivering full quality on fast ones — a key factor in viewer satisfaction.

Multicast sends a single stream of data that is shared by many users simultaneously (one-to-many). It’s efficient for many viewers watching the same live content. Unicast, in contrast, sends a separate, individualized stream to each viewer. This enables personalization (such as quality adaptation, ad insertion, user-specific DRM), on-demand playback, and works over standard HTTP/CDN infrastructure.

Unicast is becoming the norm because modern viewers expect features like on-demand streaming, personalized ads, low latency, cross-device playback, and global content delivery. Most ISPs and CDNs are optimized for unicast traffic. Multicast has limitations in flexibility, scalability, and infrastructure compatibility.

Some of the key limitations include poor support for on-demand content, difficulty implementing personalization (ads, language, subtitles), lack of compatibility with many ISPs and CDNs, higher complexity for global delivery, and constraints on analytics and content security mechanisms.

A proper CDN helps reduce latency (by bringing content close to users), supports adaptive bitrate streaming to adjust video quality based on the user’s connection, enables secure delivery (DRM, token-based access, geo-blocking), supports personalization (ads, subtitles), and offers scale to handle many individual streams. It also helps with reliability and availability via multi-CDN strategies.

It’s time to shift if your platform is expanding globally, you want to serve content across multiple types of devices, you need features like ad insertion, DRM, analytics, and personalized content, or you aim to improve viewer experience with lower latency and fewer buffering issues. For most OTT or growing streaming services, making this shift around 2026 is advisable.

Yes, unicast generally uses more bandwidth since each viewer receives a separate stream. However, with modern CDN architecture, efficient adaptive bitrate streaming, edge caching, and scaling strategies (multi-CDN), this overhead can be managed effectively. The trade-off is worth it for the flexibility, quality, and features unicast enables.

Vodlix is designed for unicast from the ground up. Features include built-in multi-CDN delivery, adaptive bitrate streaming, DRM and content protection tools, support for personalized ad delivery, cross-device playback (web, mobile, smart TVs), and the ability to deliver both live and on-demand content with high quality and low latency.
