Historical provider.
Current availability of the listed service is not confirmed.

Overview

Viblast developed a peer-assisted delivery layer and an HTML5 video player. Its October 2015 hybrid player mode supplemented an existing CDN or in-house delivery service. Current service availability remains unconfirmed.

Network

Peers supplement an underlying CDN or in-house streaming system. Viewer participation and concurrency affect the benefit; peer devices are not fixed cache PoPs.

No owned cache-city map is appropriate for this architecture. Test a replacement with the actual audience, player and fallback delivery network.

Past features

The historical player supported live and on-demand HLS/DASH playback and encrypted HLS or DRM-protected DASH streams. For a complete video workflow, check how encoding, packaging and DRM licenses will be supplied.

The 2015 hybrid mode targeted geographically concentrated, highly concurrent live viewing. It was not recommended for ordinary low-concurrency VOD. Measure bandwidth savings in a pilot and check the CDN’s own purge and request-log options.

Service status

Replace the peer-assisted layer and underlying CDN deliberately. Confirm supported player formats, DRM authorization, browser/mobile behavior and fallback when peers are unavailable. Check the current support and migration arrangement for an existing account.

History timeline

  • October 21, 2015 — Hybrid player mode announced — P2P layer supplements an existing CDN or in-house streaming system.
  • 2020–2022 — Later public repository activity — SDK/tool updates do not establish service continuity or closure.

Budgeting for a replacement

The historical hybrid mode required a subscription. Ask about current availability and prices before using it. Compare a replacement’s software fees separately from its underlying CDN bill.

  • Estimate concurrency and the actual peer offload rate.
  • Include fallback transfer, requests and media processing.
  • Confirm supported players, licensing, support and commitments.

A guaranteed offload percentage would make the estimate misleading; use measured workload assumptions.

Historical integrations

The linked public documentation repository covers historical PDN architecture, the customer portal, REST API and Wowza integration. The organization also retains iOS/Android SDKs and HLS/DASH utilities.

Check current endpoint, SDK and browser support before reusing the archived tools. Check dependency support, credentials, media/DRM handling and CDN fallback before reusing them.

What to know

For an older integration, measure audience concurrency and fallback traffic, then test the replacement player and peer-delivery layer. Keep encoding and DRM requirements separate from playback.

Planning a replacement

Run a pilot before budgeting peer-assisted savings, especially with dispersed viewers or low concurrency. Confirm current SDK and service support before building a new integration.

History

An October 21, 2015 company release from Sofia introduced hybrid delivery in Viblast Player version 6.06. Its repositories contain later work, including an Android SDK update in 2020 and a DASH utility update in 2022. Current service availability remains unconfirmed.
