DVIS II: Next-Gen Local Channel Insertion

DVIS II is a local channel insertion solution that enables MSOs to assist bulk accounts, such as Multi-Dwelling Units (MDUs), apartment buildings, retirement facilities and enterprise customers, in adding lobby feeds and other locally generated content into television channel lineups. The platform simultaneously supports QAM- and IP-based environments, offers unrivaled deployment flexibility and greatly reduces the operational overhead associated with channel insertion operations for MSOs and other service providers. ATX designed DVIS II to empower MSOs to conveniently and cost-efficiently continue to provide their commercial and residential customers with the ability to view local content alongside traditional entertainment and informational television programming as they transition their services to IPTV.

The DVIS II platform consists of a low-cost, premises-located edge encoder paired with ATX’s Enhanced Origin Server, a low-latency software engine hosted within an MSO datacenter, the public cloud or even on the premises of large enterprise customers with local area networks. ATX’s Enhanced Origin Server also features customizable authentication and authorization functionality to ensure that only end-clients associated with the appropriate accounts receive the local content.

DVIS II is the successor to the original DVIS platform, a widely deployed local insertion solution that has been installed at thousands of communal living locations to enable locally generated content to be viewed by QAM-based set-top boxes (STBs). The ongoing migration from QAM-based video services to IP has similarly created a demand for ATX’s newest insertion solution, which can convert baseband signals from cameras and other local sources into channels that can be consumed by IP-based STBs or devices, including PCs, mobile phones, tablets and smart televisions. DVIS II is managed by ATX’s Visium Manager, an all-purpose network management system MSOs can deploy to install, monitor and configure DVIS II on-premises encoders.


  • Reduce Operational Overhead: DVIS II’s deployment flexibility supports locating the Enhance Origin Server component of the solution on-premises or in a public or private cloud environment, creating the opportunity for service providers to outsource some or all of their local channel insertion operations.
  • Non-disruptive Migration to IPTV: The solution’s ability to convert baseband content from cameras and other devices to IP allows MSOs migrating subscribers to IP-based Set-Top Boxes to continue to deliver local content, such as lobby feeds and other local sources.
  • Optimize Technical Resources: Simplified installation and operations allows service providers to reduce the need for extensive engineering involvement and other ongoing resources. Management, control and configuration of the on-premises encoder by the Visium Manager also simplifies operations.
  • Realize Bandwidth and Latency Optimization: Communication between encoder and origin server is optimized to conserve upstream bandwidth and eliminate delays that could impact the timing and quality of local content.
  • Simultaneously support QAM and IP: DVIS II’s support for both QAM and IP outputs enables service providers to support both environments with a unified solution, eliminating the need for multiple systems during the transition to IPTV.


  • CMAF segmentation allows for single format transmission of source streams
  • Low-latency and On-Demand transmission to Enhanced Origin Server preserves upstream bandwidth
  • Desired ABR profiles generated in real-time by Enhanced Origin Server
  • Support for RTSP ingest and typical IP camera formats, such as motion jpeg & H.264 Remote Management
  • Supports simultaneous local channel insertion over QAM to legacy RF-only ingest STBs
  • Support for add-drop mode to replace a single program in an existing QAM multiplex
