The term is context-dependent, though: in live-streaming services, “push” often means sending a live audio-and-video feed to a platform, not distributing video for later viewing. The delivery method, storage, and equipment depend on the particular system.
What “push VOD” means
VOD is video on demand: a viewer chooses video that is available to play, rather than watching only when it is broadcast live. In a broadcast-oriented setting discussed in an Eutelsat white paper on DVB-NIP, “push” describes a delivery path for files or prepared video content that a receiver or application can use later. Content is ingested into a system and distributed toward, or made available to, receiving equipment; a viewer selects it for playback afterward.
That description is not a universal product definition. The term alone does not tell you when content is sent, where it is stored, how a catalogue is updated, or whether a receiver needs an internet return connection. Those details depend on the service and its implementation.
How push-style VOD works
- Content is prepared and ingested. A service or content operator supplies files to a server-side content-management or ingest system.
- The system distributes the content. In a push-style delivery design, content is sent toward receiving equipment or made available to a receiver-side application. The transport and schedule vary by deployment.
- A receiver or application makes it usable. Compatible equipment or software must be able to receive and handle the material. The cited DVB-NIP discussion describes receiver-side applications, but does not establish one required device for every service.
- The viewer chooses playback later. Once the content is available to the relevant receiver or application, it can be selected for viewing. The exact catalogue and storage experience are service-specific.
One motivation described for push-style file delivery is a situation where continuous connectivity is unavailable or inefficient. That is a reason a deployment might use this approach, not a guarantee that every push system works offline or performs better than internet delivery.

How it differs from live-stream “push”
The word “push” is also used for a different action in live streaming. In a Tencent Cloud guide, pushing means a host sends local audio and video to cloud servers. VOD, by contrast, refers there to stored video that can be played later. So “push VOD” and “push a live stream” should not be treated as synonyms: one concerns delivery of content for later use, while the other describes sending a live feed into a streaming service.
Push delivery compared with HLS and MPEG-DASH
HLS and MPEG-DASH are HTTP-based streaming approaches. In conventional on-demand delivery, video is packaged into segments with a playlist or manifest that describes them; a compatible player requests the files, typically from a web server or CDN. This is a request-based delivery path, rather than the broadcast-oriented push path described above.

| Aspect | Push-style VOD in the DVB-NIP context | HTTP-based VOD such as HLS or MPEG-DASH |
|---|---|---|
| Delivery path | Content is distributed toward, or made available to, receiving equipment or an application. | A player requests packaged video files over HTTP; HLS uses playlists and segments, while DASH uses manifests and segments. |
| When it is watched | Prepared content is intended for later selection and playback. | Stored, packaged content is played on demand; HLS can also support live broadcasts. |
| Connectivity and storage | The exact schedule, storage behavior, and return-channel needs depend on the deployment. | The player needs access to the hosted manifests and segments during playback; the cited documentation does not establish one storage policy for every service. |
| Compatibility | Requires a receiver or application compatible with the specific implementation; no universal device is established by the cited source. | Requires a player that supports the relevant streaming format and media. |
Apple’s HLS overview says HLS supports live and prerecorded video, can offer multiple bitrate variants, and adapts playback to network conditions. Its HLS workflow explanation describes the playlist-and-segment approach. AWS also explains packaging on-demand video into segments and manifests for CDN delivery in its CloudFront video documentation. MPEG-DASH is another HTTP-based adaptive streaming approach for live and on-demand use, as outlined by the MPEG standards overview. Neither HLS nor DASH is another name for broadcast push VOD.
What to check before choosing a push-VOD service or device
- Confirm what the provider means by “push VOD.” Ask whether it refers to broadcast delivery for later playback, live-stream publishing, or another workflow.
- Verify the implementation and compatibility. Check the specific service, standard implementation, receiver, gateway, and application requirements together. A device should not be assumed compatible merely because it supports video or a similarly named standard.
- Ask where and how content is stored. Establish whether the receiver stores files locally, accesses them through an application, or uses another arrangement, and how long content remains available.
- Clarify connectivity and catalogue updates. Ask what connection is needed to receive content, whether a return connection is required, and how new content and catalogue changes reach viewers.
- Do not infer a universal deployment from the term. The Eutelsat DVB-NIP discussion describes an architectural context, not certification of particular consumer receivers or a single workflow for every provider.
Where StreamNeo fits—and where it does not
StreamNeo is a separate service for keeping a YouTube channel live from uploaded videos. You upload a recording or build a playlist, add your YouTube stream key, and go live; StreamNeo loops the videos from the cloud. That is not DVB-NIP push VOD or a way to receive broadcast-delivered VOD. It is relevant only if your goal is a continuous YouTube live stream made from prerecorded videos.
