- Grant access to various system features based on - username / password and/or IP address. - -
Software based CSA descrambling -
- Requires a card server. - -
Internationalization -
- All text is encoded in UTF-8 to provide full international support. All major - character encodings in DVB is supported. -
1.2 Install and initial setup
-
-Parts of this documentation is also available in the Tvheadend man page. -

-

-
Starting Tvheadend -
- If you already have Tvheadend up and running you can skip this part. -

- Command line options: -

-
-f -
- Fork and become a background process (deamon). Default no. - -
-u userid -
- Run as user with 'userid'. Only applicable if daemonizing. Default is to - use the uid of 1 (daemon on most systems). - -
-g groupid -
- Run as user with 'groupid'. Only applicable if daemonizing. - Default is to use the gid for the 'video' group. - If the 'video' group does not exist, gid 1 (daemon) will be used. - -
-s path -
- Store settings in path. Default values varies depending on if - daemonizing or not. See settings storage section below for details. -
- - -
Default configuration -
- All configuration in Tvheadend is maintained via its embedded web - server running on port 9981. Just point your browser to: -

- http://hostname:9981/ -

- - By default everyone (also from remote hosts)is allowed full - access to all features / settings in the web user interface. If - this is the first time you setup Tvheadend you are most encouraged to - enter the web user interface, selected the 'Configuration' + 'Access Control' - tab and make reasonable changes. Futher help / documentationcan be obtained - inside the web interface. - -

Settings storage -
- Settings are stored in different locations depending on how Tvheadend - was started. -

- If the (-s) argument is given, that path is always used. -

- Otherwise, tvheadend will try to store settings in /var/lib/hts/tvheadend. - If this is not possible (due to access permission restriction) it will store - it in the current user home directory under .hts/tvheadend. - -

Logging -
- All activity inside tvheadend is logged to syslog using log facility. - Also, if logged in to the web interface you will receive the same log in the bottom - tab (System log). - - -
Permission to access video adapters -
- In order for Tvheadend to control video adapters on the system it - must be granted access to those devices. Most systems have a 'video' - group with write access to the video adapter devices. When Tvheadend - is started as a daemon (if Tvheadend is installed from a distibution package - this is most likely the way it is) it will automatcially change its primary group - to 'video' in order to access these groups. If your system is configured - in a different way you can either change the group membership of the - video adapters (/dev/dvb, etc) or reconfigure the Tvheadend startup - parameters. -

- If Tvheadend is started without the '-f' argument it will not daemonize - nor change its primary userid/groupid. Rather it will run with the permissions - granted to the user executing the binary. If that's the case you must make - sure the current user is granted with access to the video devices. - - -

Open ports -
- Tvheadend listens to the following TCP ports by default: -
    -
  • 9981 - HTTP server (web interface) -
  • 9982 - HTSP server (Showtime protocol) -
- There is currently no way of disabling these TCP servers, nor bind the services to - specific interfaces or other ports. - To limit access, please read the section about 'Access Control' - in the configuration chapter. - - -
Building Tvheadend from source -
- If you want to build tvheadend from source, visit - this page. - Please notice that wiki development site only reflects the work - in HEAD (-current). The instructions should not deviate much should you want to - build a released version from source, but you never know. -
-
-
1.3 Frequently Asked Questions
-
- -
- -
Why does Tvheadend deliver data over TCP to Showtime? I thought it was - bad to use TCP for realtime sensitive traffic? - -
- 'HTSP' - the protocol used for streaming TV, sending meta information - updates and RPC between Tvheadend and Showtime uses a transmission - scheduler with multiple queues on the Tvheadend side. This means that - Tvheadend can measure the available bandwidth between itself and the - mediaplayer and when congestion happens it's even capable of dropping - less important data (such as B-frames). HTSP has been tested over WAN - links and DSL connections with zero picture/audio artifacts. -

- It's possible to get view drop statistics and bitrates directly in - Showtime. (Open the menu when watching a TV-channel and switch on - 'Detailed Information') - -

-
2 Electronic Program Guide
-
-Tvheadend has a built in Electronic Program Guide. The EPG is an in memory -database populated with all the information about events received from -the DVB networks or from XMLTV. -

-The EPG tab displays a filterable paged grid containing all the events -sorted based on start time. - -

-

-
Filtering (or searching) -
- In the EPG top tool bar you can access four input fields. - These are used to filter/search for events. The form uses implicit AND - between the input fields. This means that all filters must match - for an event to be displayed. -
-
[Search title...] -
- Filter on the event title. The filter uses case insensitive regular - expression. If you don't know what a regular expression is this means - that you can type just parts of the title and filter on that too. - (No need for exact matching). -
[Only include channel...] -
- Only display events from the selected channel. -
[Only include tag...] -
- Only display events from the channels which are included in the selected tag. - Tags are used for grouping channels and is configured by the administrator. -
[Only include content...] -
- Most DVB networks classify their events into content groups. This field - allows you to filter based on content type. -
- Thus, if you only would like to browse Movies from your HD-channels you - would select 'HD channels' in the [Only include tag...]-field, and select - 'Movie / Drama' in the [Only include content...]-field. -

- Notice that you don't have to press a 'Search' button, the grid immediately - updates itself as you change the filters. -

- If you would like to clear all filters, just press the [Reset] button. - -

Paging - -
- In an installation with many (hundreds of) channels and full EPG feed from - both DVB and XMLTV there will be tens of thousands of events in the database. - Therefore the EPG display employs a paging bar at the bottom of the grid. - Use it to browse backwards and forwards in the EPG. It also displays the - total amount of events matched by the current query. - -
Event details and recording -
- If you click on a single event, a popup will display detailed information - about the event. It also allows the user to schedule the event for recording - by clicking on the [Record program] button. -

- -

- To close the popup, just close it with the [X] window button. - The popup is not modal and you can open as many detailed information popups - as you want. - - -

Autorecordings -
- Should you wish to record all events matching a specific query. (Record - your favourite TV-show, etc) you can press the 'Create Autorec' button - in the top toolbar. -

- A popup with details about the to-be-created autorecording rule needs to - be confirmed before the rule takes effect. -

- -

- The autorecordings can later be changed/deleted in under the - 'Digital Video Recorder'-tag. Use that editor if you temporary want - to disable an autorecording or make adjustments, etc. -

-
-
3 Digital Video Recorder
-
-Under the 'Digital Video Recorder' tab you can administer and list status of -individual recordings and configure rules for the automatic recorder. -

-To access the DVR tab you must be logged in sufficient access credentials. -

-For general configuration of the DVR (such as where and how to store the recordings, -please see the DVR section in the configuration chapter) -

-
3.1 DVR Log
-
-The DVR log displayes a paged grid containing all schedulded, current and completed -recordings. The list is sorted based on start time. -

-Use the bottom toolbar (not displayed in this manual) to navigate between pages -in the grid. - -

-To see more details about a recorded event, just click on it and a popup will appear: -

- -

-In this popup you can cancel a scheduled recording or abort a recording in progress. -To close the popup, just close it with the [X] window button. -

-Once the recording is completed there will be a clickable link to the recorded matroska -file so you can download it directly from the interface. -

-
3.2 DVR Autorecorder
-
-The 'Automatic Recorder' is used to create rules that will trig automatic recording of -events. You can use this to record you favourite TV show(s), record all movies on -a specific channel, etc. -

-It's also possible to create a recording based on a query in the EPG. For more information -about that, please read the EPG chapter. -

- -

- The tags are listed / edited in a grid. - -

- -

-The columns have the following functions: - - -

-
Enabled -
If checked the rule is active. If unchecked the rule will not trig any new - recording sessions. - -
Title -
- Only matches events with the given title. The filter uses case insensitive regular - expression. - -
Channel -
- Only match events from the given channel. - -
Channel tag -
- Only match events from the channels which are included in the given tag. - Tags are used for grouping channels and is configured by the administrator. - -
Content group -
- Only match events belonging to the given content group. - -
Created by -
- Free text field, but will be copied to the recording session. - -
Comment -
- Free text field, not used for anything else. -
- -
-
4 Configuration and administration
-
- -

-All configuration and administration of Tvheadend is conducted via the -built in web user interface. - -

-To access the configuration tab (and its sub panels) you need Admin-access. -For details about access control, please see the 'Access-Control' section in this chapter. - -

-Each subsystem of Tvheadend is configured via its own tab: - -

- - -

-
4.1 Access configuration
-
- -Setting upp access control is an important initial step as the system initially is -wide open. - - - -

-When Tvheadend verifies access is scan thru all the enabled access control entries. -The permission flags are combined for all matchin access entries. -An access entry is said to match if the username / password matches and the IP source -address of the requesting peer is within the prefix. -

- -The access rules are listed / edited in a grid. - -

- -

-The columns have the following functions: - -

-
Enabled -
Make the entry participate in access control. If disabled, the entry - is inactive. - -
Username -
- Name of user, if no username is needed for match it should contain a - single asterix (*). - -
Password -
- Password to combine with user, if username is '*' (unused), the password - should be the same. - -
Prefix -
- IPv4 prefix for matching based on source IP address. - If set to 0.0.0.0/0 it will match everything. - -
Streaming -
- Enables access to streaming function. The 'streaming' access is enough to - make Showtime (over HTSP) work. - -
Video Recorder -
- Enables access to all video recording functions. This also include administration - of the auto recordings. - -
Web interface -
- Required for web user interface access. Also gives access to the EPG. - -
Admin -
- Enables access to the Configuration tab. - -
Comment -
- Allows the administrator to set a comment only visible in this editor. - It does not serve any active purpose. -
- -

-Let's also take a look at an example: -

- -

-First line gives clients orignating from 192.168.0.0 - 192.168.0.255 network -access to streaming functions. Typically you would use this for your -local media players at home (Allthough Showtime can prompt for username & password -in its HTSP client) -

-The second line adds a user with world wide access who might want to modify -recordings, etc, perhaps from the job, or mobile phone. -

-The third line provide admin access to the 'admin' user. As an extra precaution this -user is only allowed to log in from the home network. -

- -

-
4.2 Channel configuration
-
- - - -
- The channel tab is divided in three parts: -
-
The channel list (to the left) -
Use this list to select the channel you wish to work with. - You can also drag a channel from this list onto the right side of - the view to merge the dragged channel with the currently selected one. - -
Channel details (right top) - -
-
Channel name -
Name of the channel as presented in EPG and external interfaces. - Changing name of a channel does not interfere with scheduled - recordings etc. - -
XML-TV Source -
Name of the XML-TV channel. If you have XML-TV enabled you can - select which XML-TV channel to obtain data from. By default - Tvheadend tries to match the name itself, but sometimes it might - not match between the XML-TV source and the TV provider so in - such cases you can change it yourself. - -
Tags -
Each channel can be bound to a zero, one or many tags. - The tags are used for multiple things and it's up to you how - you wish to use and name them. Tags can be used to aid searching - in the EPG if you have many channels. The tags are also presented - in the Showtime Media player. - To (de-)select multiple tags, just hold the CTRL-button as with - any multi-selection list. - -
Delete channel -
This button will delete the channel (and any scheduled recordings - tied to it). You will be asked to confirm before the actual - delete is executed, but after that, there is no way to recover. -
-
Changes to any of these settings must be confirmed by pressing the - 'Save configuration' button before taking effect. If you select - a different channel any unsaved changes will be lost. It is, however, - perfectly fine to switch Tab (if you want to check anything, create - a new tag, etc) and come back without any changes being lost. - - -
Transports bound to channel (right bottom) -
In this view you can examine and enable/disable each of the transports - bound to the channel. You may wish to disable a transport if it - temporary out of service or in other terms problematic. - The status of the enable checkbox is saved when the 'Save configuration' - button is pressed. - - -
-
- -
-
4.3 XML-TV configuration
-
- - - -

- This tab is used to configure XML-TV. For more information about XML-TV - and its use, please visit - http://www.xmltv.org. - -

- Configuration options: -

-
XML-TV Source -
Select which grabber to use. - When the drop down list is pressed Tvheadend will issue a scan - for available grabbers on the host system. This result will be - cached in the web user interface. Thus, if you need to rescan due to - a newly installed grabber you must reload the web interface. - (There is no need to restart Tvheadend itself). - - When you select a grabber more information will pop up regarding - further configuration of the grabber. - -
Grab interval -
Hours between each grab. - -
Enable grabbing -
Uncheck this if you wish to disable grabbing. -
- Changes to any of these settings must be confirmed by pressing the - 'Save configuration' button before taking effect. - -
-
4.4 Tags configuration
-
- - - -

- This tab is used to configure channel tags. - Tags are used to define a set of channels. - Notice that nothing prohibits a channel to be a member of multiple tags. - Also, there is no requirement to configure tags for running Tvheadend - itself. It is, however, required if you run Tvheadend together with Showtime. -

- The tag-sets are used for: -

- -

- The tags are listed / edited in a grid. - -

- -

- The columns have the following functions: - -

-
Enabled -
Make the tag available in the rest of the system. If the tag is - not enabled it is only presented in this grid for the administrator. - -
Name -
Name of the tag. Changing the tag name does not interfer with any - automatic recordings, groups, etc. - -
Internal -
Tags are exported via HTSP (to the Showtime Mediaplayer) and used - there for grouping of TV channels. If you do not wish to export a - tag you can flag it as internal only. - -
Icon -
Full path to an icon used to depict the tag. This can be a TV network - logotype, etc. - -
Icon has title -
If set, presentation of the tag icon will not superimpose the tag - name on top of the icon. - -
Comment -
Allows the administrator to set a comment only visible in this editor. - It does not serve any active purpose. -
-
-
4.5 Digital Video Recorder configuration
-
- - - -

- This tab is used to configure operation of the Digital Video Recorder. - It is not used for scheduling or administration of individual recordings. - -

- Configuration options: -

-
Recording system path -
Path to where Tvheadend will write recorded events. If components of - the path does not exist, Tvheadend will try to create them. - -
DVR Log retention time (days) -
Time that Tvheadend will keep information about the recording in - its internal database. Notice that the actual recorded file will not - be deleted when the log entry is deleted. - -
Make subdirectories per day -
If checked, Tvheadend will create a new directory per day in the - recording system path. Only days when anything is recorded will be - created. The format of the directory will be 'YYYY-MM-DD' (ISO standard) - -
Make subdirectories per channel -
If checked, Tvheadend will create a directory per channel when storing - events. If both this and the 'directory per day' checkbox is enabled. - The date-directory will be parent to the per-channel directory. - -
Include channel name in title -
If checked, Tvheadend will include the name of the channel in the - event title. This applies to both the titled stored in the file - and to the filename itself. - -
Include date in title -
If checked, Tvheadend will include the date for the recording in the - event title. This applies to both the titled stored in the file - and to the filename itself. - -
Include time in title -
If checked, Tvheadend will include the time for the recording in the - event title. This applies to both the titled stored in the file - and to the filename itself. -
- Changes to any of these settings must be confirmed by pressing the - 'Save configuration' button before taking effect. -
-
4.6 DVB configuration
-
- - - -

- This tab is split in two panes. To the left is a tree which, at root level, - contains all DVB adapters found by Tvheadend during startup. - - -

-
Step by step configuration of DVB -
- The DVB configuration is perhaps the most tricky part to configure - in Tvheadend. Therefore, this section begins with a step-by-step - guide. -
    -
  • Click on an adapter in the left pane. -
  • Click on 'Add mux(es)'. A popup window will appear: -
    - -
    - For DVB-T and DVB-C adapters, expand appropriate country. - DVB-S adapters only have one folder to expand called 'Geosynchronous Orbit'. - In these folders you find a list of available networks. - Select the appropriate network and press the 'Add' button. - -
  • - Tvheadend will now immediately start to probe each mux for available - services. Expand the DVB adapter in the tree - and wait until all muxes has been visisted - at least once (Status of all multiplexes should change from 'Unknown' - when a mux has been visited). - -
  • - You can now, if you want, verify that the mux scanner has found - services by expanding the mux nodes. - -
  • - Select the adapters again and press 'Probe services'. - A popup will ask you to confirm this action. Press 'Yes'. - The Service probe will scan through all services on all muxes on the - adapter and map them to channels with the corresponding name. - Progress and result for each service is displayed in the 'System Log' - at the bottom of the application. Wait until the probing is completed. -
  • - Done! You can click over to the 'Channels' configuration tab and - inspect all working channels. - - -
-
DVB Adapters -
- A DVB adapter represents a piece of hardware attached to the system. - DVB receivers with dual tuners will present themself as two adapters - to the Tvheadend application. Tvheadend support DVB-T, DVB-C and DVB-S - adapters. -

- When an adapter is selected, the right pane displays configurable items - for the adapter. Also available in the right toolbar is a set of operations - that can be performed on the adapter. -

- Underneath each adapter in the tree is a list of DVB muxes. - For more information about muxes, see further down. -

- There is currently no way of adding a new adapter to Tvheadend when running. - If a new adapter is plugged into the system Tvheadend needs to be restarted - in order to detect it. -

- If Tvheadend has configuration for an adapter and the adapter is missing - upon startup the configuration will be left untouched in case the adapter - will be back in the future. There is currently no way to remove configuration - for a no longer present adapter. -

- Warning: Unplugging an DVB adapter (USB, etc) during operation (i.e when - Tvheadend is running) can result in deadlocking the kernel USB subsystem, - most likely requiring a system restart. -

- Warning2: Suspending a system is (from a USB driver perspective) equivalent - to a unplug/insert event. Thus, suspending a system running Tvheadend - with USB adapters is not recommented at the moment. - -

DVB Multiplexes -
- To put it simply, a DVB multiplex is a digital signal modulated - at a specific frequency that carries a number of servies (where a - service could be, but is not limited to, a TV channel). -

- There are currently no operations that can be performed on a single mux. - -

DVB Services -
- A service is equivivalent to a TV channel. -

- There are currently no operations that can be performed on a single service. -

-
-
4.7 CWC configuration
-
- - Tvheadend support connecting to card servers for so called softcam descrambling. - -

- - -

- The servers are listed / edited in a grid. - -

- -

- The columns have the following functions: - -

-
Enabled -
If selected, connection will be tried to be established and retained up. - If unselected, Tvheadend will disconnect (if connected) and not try to reconnect. - -
Hostname -
Server hostname. DNS lookup is performed upon every connection attempt. - -
Port -
Server TCP port - -
Username -
Username to use. - -
Password -
Password to use. - -
DES Key -
Initial DES key. - -
Comment -
Allows the administrator to set a comment only visible in this editor. - It does not serve any active purpose. -
