--- title: Demo edition url: https://doc2.pstreamer.tv/en/manual/install/demo.html lang: en product: Perfect Streamer version: 2.0.2.412 --- # Demo edition The Perfect Streamer **demo edition** is a free edition for technical evaluation: it lets you check stream processing quality, the transport protocols and the web interface on your own hardware before buying. It is installed as a separate package, `pstreamer-demo`, works without a protection key, needs no activation and has no time limit. The package includes the `ts_analyze` utility, a transport stream analyser following ETSI TR 101 290 ([TS Analyze Perfect Streamer Toolkit v2.4 — TR 101 290](../toolkit/ts_analyze.md#toolkit-ts-analyze)); the node’s own analyser in the demo edition is the basic one. > **Warning** > > The demo edition is for evaluation only. Commercial use and operation in a production environment are prohibited by the demo edition licence agreement (Licence agreement). Production use requires a full licence; the full edition can be tried out on a trial licence (Moving to a trial or full licence). ## Comparison of editions Features that the table does not list as available are absent from the demo edition altogether: they are not part of its build and cannot be enabled. The web interface does not hide such features but shows them inactive, marked “Not available in the demo”; in the lists of input and output types the unavailable types are visible but cannot be selected. Where a limit applies, the interface names it, for example “Demo edition: no more than 5 streams.”. | Feature | Demo edition | Full edition | | --- | --- | --- | | Streams | up to 5, SPTS only | SPTS and MPTS | | Stream inputs and outputs | 1 input and 1 output | several, with input redundancy | | Input and output protocols | PS1, SRT, UDP, RTP | all, see [Planning and data transmission protocols](../planning/index.md#planning) | | Peers | up to 5 access logins for OTT, PS1 and SRT, one connection each | unlimited | | Multiplexer and demultiplexer | no | yes | | Adaptive streams (ABR) | no | yes | | Analyser | basic: bitrate, CC errors, PID list | full, including TR 101 290, SCTE-35 and PCR drift | | OTT | HLS/DASH delivery without DVR | delivery with DVR, timeshift and archive | | Meshwork | up to 3 nodes (2 configured peers), no subdomains | unlimited, with subdomains | | DVB reception | no | yes, including descrambling (CI/CAM, BISS) | | EPG | no | EIT capture and generation, XMLTV | | Transcoding | software only, one profile | software and hardware (NVIDIA, Intel) | | PS1/SRT and OTT encryption | no | yes | | PCR correction, jitter smoothing, CBR, PID remapping | no, the stream passes through unchanged | yes | | Mosaic, test streams, file channels | no | yes | | Monitoring export (Zabbix, Prometheus, InfluxDB, Nagios) | no; alerts in the web interface and by e-mail | yes, plus Telegram and scripts | | Viewer authorisation via billing, ACME certificates | no | yes | | Web interface accounts | up to 3 | unlimited | | Settings backup and rollback | yes | yes | | Protection key and activation | not required | SL or HL key | The demo edition is recognised by the version string with the `-demo` suffix (for example, `2.0.2.410-demo`), the “Demo” flag on the [License](../webui/administration.md#webui-license) screen and a panel at the top of the web interface that cannot be closed: “Demo edition — for evaluation only, commercial use is prohibited.” with a “Buy a licence” link. A request that exceeds the limits of the demo edition is rejected by the node as a whole, and nothing is changed; the web interface shows the reason as is, and it begins with `demo edition:`. For example: - `demo edition: this list holds at most 5 item(s)` — adding a sixth stream or login, or a second input or output of a stream; - `demo edition: key "drm-mode" can only be 0 (not in the demo)` — an attempt to enable a feature that the demo edition does not have; - `demo edition: a Meshwork of at most 3 nodes (2 peers)` — an attempt to configure a third Meshwork peer. No alert is raised in this case. ## Installation The demo edition is supplied as `pstreamer-demo` packages for the RHEL family (x86_64, RPM) and the Debian family (amd64, DEB). The package is installed from a file: apart from system libraries, it has no dependencies. RHEL family: ```sh $ sudo yum -y install ./pstreamer-demo-.x86_64.rpm ``` Debian family: ```sh $ sudo apt-get install ./pstreamer-demo__amd64.deb ``` The `pstreamer-demo` and `pstreamer` packages are mutually exclusive: only one of them can be installed on a server. The demo edition does not need the **aksusbd** protection service. No activation is required: the **pss** service starts right after installation. From there, proceed as in [Initial settings](../first_start/index.md#first-start-initial-settings): the web interface is on port `8808`, the login and password are `admin`; change them straight away. ## Moving to a trial or full licence The features of the full edition are tried out on a trial licence: it is free, lasts one month and lifts all the limits of the demo edition. Request it, or a commercial offer, in the Help Center: [https://support.pstreamer.tv/crm/](https://support.pstreamer.tv/crm/). 1. Remove the `pstreamer-demo` package: the packages are mutually exclusive, and the package manager does not replace the demo edition by itself. The settings file `/opt/pss/config/pss.json` stays in place when the package is removed. 2. Install the `pstreamer` package ([Installation on RHEL-family systems](rhel.md#install-rhel) or [Installation on Debian-family systems](debian.md#install-debian)). 3. Perform the activation — [Temporary activation and startup](../first_start/index.md#first-start-activation). The full edition picks up the settings made in the demo edition. Moving back, from the full edition to the demo edition, does not trim the settings. A settings file that the demo edition cannot run as is (more streams, inputs, outputs or logins than its limits allow, or features enabled that it does not have — MPTS, DVR, DRM, CBR) is not loaded: the file is moved unchanged to `/opt/pss/config/bad/`, and the node starts on the last good configuration, as with any loading error ([Behavior at startup and on configuration errors](files.md#startup-config-errors)). The web interface shows a loading-error alert with the reason and the place where the file was saved. Sections that the demo edition lacks altogether (EPG, DVR storages, DVB adapters) are skipped with a warning in the log. To work in the demo edition, configure it within its limits. ## Licence agreement The demo edition is distributed under a separate licence agreement (Enterprise Demo License Agreement); after installation its text is in the file `/opt/pss/COPYRIGHT`. The main terms are: - technical evaluation, laboratory testing and compatibility checks only; use in a production environment is prohibited; - commercial use is prohibited, including broadcasting, OTT and IPTV services, content delivery and cloud services; - circumventing the limits of the demo edition, modifying it and distributing it are prohibited; - the period of use is not limited: the demo edition is free and works without a time limit, but for evaluation only. The licensor is Perfect Soft. The agreement is governed by the law of England and Wales.
