EPG/PSI system for TV operators - The Casis Modernization Story

Client:

Industry:

Digital Broadcasting & Pay TV Infrastructure

WHAT WE DID:

Reconstructed system knowledge and modernized the architecture to support current standards, security, and infrastructure.

RESULTS:

Stabilized a 5M+ LoC system, ensured zero downtime for global operators, and delivered a secure 4K-ready, production-grade release.

When Enghouse (TSE: ENGH) shifted its strategic focus, CASIS – the electronic EPG/PSI backbone of major TV networks – needed a new home. 7bulls.com stepped in to take over, reverse-engineer, and modernize it, ensuring a seamless transition and a roadmap for a secure 4K-ready future.

THE CHALLANGE

Our partner Enghouse (TSE: ENGH, formerly SeaChange International), had spent over a decade developing CASIS (electronic EPG/PSI Scheduler) – a sophisticated solution for digital broadcasting and EPG management. With over 30 global deployments, CASIS has become the "invisible" essential engine for Tier 1 operators.

However, as SeaChange pivoted its product lines toward different areas of development of multiscreen video solutions. The risk of losing support for existing global customers entirely. A growing need for interventions, including support for modern operating systems and newer hardware integrations. End-customers were already pressing for security patches and support for emerging standards, including security, 4K descriptors and AC-4 features.

We took over the project at a high-stakes moment with minimal knowledge handover. Our team successfully:

Reconstructed knowledge: Navigated and audited a massive codebase of over 5 million lines of code (LoC).
Delivered rapid modernization: Within just one year, we issued a major new version of the system, addressing core pain points and security vulnerabilities.‍
Handled a complex deployment: Managed dozens of interconnected services and tens of dedicated hardware integrations to ensure zero downtime for operators.
