A concurrent stream limit is the maximum number of devices that can play video on one account at the same moment. When the limit is reached, a further device is refused or an existing stream is stopped. ## How a concurrent stream limit works Each time playback starts, the player registers a session with the service and then sends a regular heartbeat while it plays. The service counts active sessions for the account. If a new session would exceed the plan's limit, it is refused with a message naming the devices already watching. Sessions that stop sending heartbeats expire after a short interval, so a closed app or a lost connection frees the slot. ## Concurrent stream limit vs device limit A stream limit counts devices playing right now. A device limit counts devices registered to the account in total, whether or not they are playing. Services often use both: for example five registered devices, of which two may stream at once. ## Choosing the limit - One stream suits a low-priced individual plan - Two to four suits a household plan and is a common upgrade reason - Pay-per-view tickets are normally limited to one stream, since a shared ticket is a lost sale - Rights holders sometimes set the maximum in the license ## Concurrent stream limit on RentAnOTT Concurrent-stream caps and device limits are part of controlled access on RentAnOTT, managed per plan in the CMS alongside devices and sessions. [See security features](https://www.rentanott.com/features#security). ## Related terms - [Device limit](https://www.rentanott.com/glossary/device-limit) — A device limit is the maximum number of devices that can be signed in or registered to a single streaming account. When the limit is reached, the viewer must remove a device before adding another. - [Password sharing](https://www.rentanott.com/glossary/password-sharing) — Password sharing is the use of one streaming account by people who are not part of the subscriber's household, so that several households watch on a single subscription. It ranges from a family member in another city to credentials sold or posted publicly. - [Subscription tier](https://www.rentanott.com/glossary/subscription-tier) — A subscription tier is one of the plans a streaming service offers at a given price. Tiers differ in what the subscriber gets, such as video quality, simultaneous streams, downloads, the catalog included or whether ads are shown. - [Concurrent viewers](https://www.rentanott.com/glossary/concurrent-viewers) — Concurrent viewers is the number of people watching a service's video at the same moment. The highest value reached, peak concurrency, determines how much streaming capacity the service needs. - [Signed URL](https://www.rentanott.com/glossary/signed-url) — A signed URL is a web address for a video stream that includes a cryptographic signature and an expiry time. The CDN serves the content only if the signature is valid and the link has not expired, so a copied or shared link stops working. Using signed URLs for playback is called tokenized playback. - [Secure video streaming](https://www.rentanott.com/glossary/secure-video-streaming) — Secure video streaming is delivering video so that only authorized viewers can watch it and copies are hard to make. It is achieved by combining several layers: encrypted delivery, access tokens, DRM, account controls and watermarking. - [Pay-per-view](https://www.rentanott.com/glossary/pay-per-view) — Pay-per-view (PPV) is a model where a viewer pays once to watch a single program, most often a live event such as a fight, a match or a concert, rather than subscribing to a channel or catalog. ## Further reading - [OTT subscription plans and tiers](https://www.rentanott.com/blogs/ott-subscription-plans) - [Pay-per-view for IPTV and OTT](https://www.rentanott.com/blogs/iptv-pay-per-view) - [Pricing](https://www.rentanott.com/pricing) ## Frequently asked questions ### Is a concurrent stream limit the same as concurrent viewers? No. A stream limit applies to one account. Concurrent viewers is the number of people watching across the whole service at once, which is a capacity figure. ### Does a stream limit stop password sharing? It limits it. A shared account still works, but only for as many people as the plan allows at one time, which pushes heavy sharers toward a higher tier or a second account. ### Do downloads count toward the limit? Usually not while playing offline, since the device cannot report a session. Services control downloads separately, by limiting the number of devices that may hold them.
