Operator-Grade Streaming, Delivered as a Service.
White-label VOD, Live TV, and CDN-as-a-Service platform purpose-built for ISPs, telcos, and operators worldwide. Replaces legacy Telebreeze/Stalker middleware with a modern, pure-Rust platform featuring smart ABR transcoding, ISP edge servers, and per-subscriber billing.
A KaritKarma ProductThe Problem
Legacy IPTV middleware is a dead end.
Telebreeze, Stalker, and Ministra were built for a world of MPEG-2 multicast and set-top boxes. The streaming world has moved on. Your middleware hasn't.
ISPs and telcos worldwide spend $50-200K on legacy middleware that can't handle ABR streaming, modern DRM, smart TV apps, or per-subscriber analytics. Every operator is stuck with the same outdated technology from 2005.
Legacy Middleware
Telebreeze, Stalker/Ministra, and similar IPTV middleware were built for MPEG-2 multicast. They cannot handle ABR, DRM, multi-CDN, or modern subscriber analytics.
Proprietary Black Boxes
Closed-source middleware with per-server licensing. No API access, no customization, no integration with your billing or identity systems.
Upfront Licensing
Legacy platforms charge massive upfront license fees plus annual maintenance. Per-server pricing penalizes growth.
Edge CDN for ISPs
No existing platform deploys caching servers inside ISP networks. All traffic flows from central origin, wasting transit bandwidth and degrading quality.
Complete Platform
Everything an operator needs. Nothing it doesn't.
16 capabilities across content delivery, platform operations, subscriber apps, and security — all integrated, all multi-tenant, all built in Rust.

FAQ
Common questions
What is ViewCasta?
ViewCasta is a white-label VOD, Live TV, and CDN-as-a-Service platform purpose-built for ISPs, telcos, and operators worldwide. It replaces legacy Telebreeze/Stalker/Ministra middleware with a modern, pure-Rust platform featuring 14 microservices. ViewCasta handles everything from content ingestion and smart ABR transcoding to ISP edge CDN deployment, multi-DRM, per-subscriber billing, and white-label apps for every major device platform.
How does ViewCasta replace Telebreeze or Stalker middleware?
ViewCasta is a ground-up replacement. Where Telebreeze and Stalker are monolithic PHP/Java systems designed for MPEG-2 multicast STBs, ViewCasta is built as 14 Rust microservices supporting modern ABR streaming (HLS/DASH), multi-DRM (Widevine/FairPlay/PlayReady), smart per-title transcoding, ISP edge CDN servers, and white-label apps for Android TV, Apple TV, Fire TV, Roku, iOS, Android, Web, and Samsung Tizen. Migration tools import existing channel lineups and subscriber databases.
What devices does ViewCasta support?
ViewCasta provides white-label apps for Android TV, Apple TV, Fire TV Stick, Roku, Samsung Tizen Smart TVs, iOS (iPhone/iPad), Android phones and tablets, and responsive web browsers. All apps are operator-branded with custom themes, logos, and color schemes. A single codebase ensures feature parity across all platforms.
How does the ISP edge CDN work?
ViewCasta deploys lightweight caching servers inside ISP POPs (points of presence). Popular content is pre-positioned during off-peak hours using intelligent warming algorithms. Live TV segments are cached at the edge with sub-second propagation. The result is 95%+ cache hit ratios, eliminating upstream transit costs for the ISP while delivering superior playback quality to subscribers. ISPs provide rack space; ViewCasta manages the software.
What DRM does ViewCasta support?
ViewCasta supports all three major DRM systems: Google Widevine (L1 and L3), Apple FairPlay Streaming, and Microsoft PlayReady. The DRM Gateway microservice handles multi-DRM license delivery, token-based URL signing, geo-fencing, concurrent stream limits, and device fingerprinting. Content is encrypted once and served with per-device license requests.
How does per-subscriber billing work?
Operators pay ViewCasta per active subscriber per month. There are no upfront license fees, no per-server costs, and no per-platform app surcharges. The pricing includes the platform, apps, DRM licensing, and support. Transcoding is billed per-minute of processed content. Edge CDN hardware is deployed at cost (ISP provides rack space and power). Volume discounts apply at 10K, 50K, and 100K+ subscriber tiers.
Can ViewCasta integrate with our existing billing system?
Yes. ViewCasta exposes a full REST API and webhook system for BSS integration. Subscriber provisioning, entitlement changes, and usage events can be synced with your existing billing and CRM systems. For operators without a billing system, ViewCasta includes built-in per-subscriber billing via LoneSock Pay with support for bKash, Nagad, Stripe, and card payments.
Is ViewCasta multi-tenant?
Yes. ViewCasta is built as a multi-tenant SaaS platform from the ground up. Each operator (ISP, telco, cable company) runs as an isolated tenant with their own branding, content library, pricing plans, subscriber base, and analytics dashboards. A single ViewCasta deployment can serve dozens of operators simultaneously with complete data isolation.
What codecs and quality levels does ViewCasta support?
ViewCasta supports H.264/AVC, H.265/HEVC, and AV1 encoding with hardware acceleration via NVIDIA NVENC and Intel QSV. Quality goes up to 4K UHD with HDR10, HDR10+, HLG, and Dolby Vision pass-through. Smart per-title encoding uses VMAF analysis to optimize bitrate ladders for each piece of content, delivering the best quality at the lowest bandwidth.
How long does deployment take?
A typical ViewCasta deployment takes 4-8 weeks depending on the operator size and existing infrastructure. This includes platform provisioning, content ingestion pipeline setup, transcoding configuration, edge CDN deployment, app customization and store submission, subscriber data migration, and staff training. The SaaS model means no on-premise platform servers — only edge CDN nodes are deployed at ISP sites.
