1.1. Overview

1.1.1. Architecture

Elecard Boro VoD is built on a client-server architecture made up of 2 parts:

  • Boro VoD Probe — a software component of the system that analyzes media files from storage by validating container, audio, video, and metadata in accordance with predefined test templates. A group of Boro VoD probes can be combined into a cluster to ensure higher performance and on-demand scaling of the solution.

  • Boro VoD Server — a software component of the system that manages probes and validation tasks, collects results, and generates and stores reports.

1.1.2. Key Features

  • Comprehensive media file validation

    Check compliance of container, audio, video, and metadata with the test template. Basically, a test template is a set of tests, each aimed at analyzing a specific parameter or searching for errors. To learn about what tests are available, see Web Interface → Templates → List of Tests (more on that).

  • Flexible template system

    Boro VoD offers a set of ready-made validation templates that comply with industry standards. Apart from that, users can create their own templates or configure the existing ones. To learn how templates work, see Web Interface → Templates (more on that).

  • Validation Tasks Reporting

    Once a validation task is over, a detailed PDF, CSV, or JSON report will be automatically created. A report includes an in-depth description of the analyzed media file, detected inconsistencies, and errors with timestamps in the media file.

  • Intuitive Web Interface

    Lets multiple users simultaneously access the system via browser to manage test templates, assign tasks, track statuses, and monitor results.

  • Project System

    Create projects, allow registered users access, and assign roles within a project.

  • Client-Server Architecture

    A group of Boro VoD probes analyzes media files from storage. The central Boro VoD server manages probes as well as generates and stores reports.

  • Scalability

    Boro VoD probes make it possible to take advantage of multi-core servers. The solution makes it possible to quickly deploy extra probes and combine them into a project-specific cluster, as well as distribute tasks among in-cluster probes via load balancer. This ensures on-demand scalability for daily monitoring of large amounts of media files.

  • API

    Boro VoD offers an API for integrating the solution to a full-fledged, automated media file preparation and management system.
