Timers，Settings

• Channel List

A user may configure the DVB-T to use exclusively TV, Radio or Data services, this feature is

known as Channel List Mode.

A user can select a Channel List Mode using the configuration dialog; it is not permitted to

select a Channel List Mode that contains no services.

When the channel list mode is enabled the program up and down buttons on the remote control

will only select those services in the current Channel List Mode, and all EPG’s will only show those

services in the current Channel List Mode.

It is still possible to select a service using the service’s RSN even if it is not a member of the

currently selected Channel List Mode.

Note that if the user has selected a favorite list then the Channel List Mode acts as a filter on top

of the selected favorites list.

Service list configuration

The Channel List dialog in the “Main Menu” allows a user to edit the services displayed.

33

The Channel List dialog displays all services known to the application and provides the following

features:

Deleting of services

Editing the name of services

Lock services for parental control

Selecting the channel list dialog will turn off any channel list mode or favourite mode previously

selected by the user.

The Channel List dialog cannot be accessed if there are no services available.

• Favourite

A favourites list enables the user to select a subset of services they consider favourite. The

DVB-T allows the user to have up to five different favourites lists. Favourites lists are defined in the

favourites dialog, which can be accessed by selecting the favourites button on the Channel List

dialog and via the Main Menu.

The favourites dialog contains a scrolling list of all services and a set of buttons to enable the

user to toggle a service’s inclusion in a favourites list. Icons indicate the services that are members

of a favourites list. The currently selected service is displayed in the background of the favourites

dialog.

34

The favourites mode can be enabled from the Configuration dialog in the “Main Menu”. The user

cannot select a favourites list that contains no services. When an user selects a favourites list, all

EPG’s will show only those services in that favourite list.

When the favourites mode is enabled, the program up and down buttons on the remote control

will only select those services selected as favourites, and all EPG’s will only show the services in

the current favourite list.

It is still possible to select a service using the service’s RSN even if it is not a member of the

currently selected favourites list.

The Channel List Mode, described later in this document, will also filter a selected channel list.

For example when a user selects Channel List Mode TV and Favourites

List 1, only those services in Favourites List 1 that are of type TV will be used .

The Favourites dialog cannot be accessed if there are no services available.

• Now/Next EPG

An EPG dialog is provided that allows the user to view the current and next program playing on

each service.

35

In this dialog the service currently selected is minimized to approximately ¼ of the screen and

displayed in the top right. A list of channels and the corresponding current and next programs is

displayed. The user can navigate up and down the list of channels and highlight either the now or

next program.

Information for the highlighted program is displayed in the box to the left of the video. This

information includes the start/end time of the program, the program genre in brackets, and a

synopsis of the program content.

A user may select a service by highlighting a program in the “now” list and pressing the “Select”

key. Reminder timers can be set for the next program on each service, a user highlights the ”next”

program that they wish be reminded of and presses select. A clock icon is displayed next to those

“next” programs that have reminders set.

The Now/Next Electronic Program Guide cannot be accessed if there are no services available.

Extended Schedule EPG (8 Day Electronic Program Guide) with Timeline

Extended Schedule EPG information is presented using a timeline format either, on a banner for the

current service, or as a full screen dialog showing multiple services.

The timeline format uses buttons to represent a program, each button is scaled to the length of a

program and displayed in relation to a timescale that is usually shown as a title.

Programs that end at the same time as the end of a displayed timeline’s range are indicated by

displaying the end of that program a few pixels before the right edge of the timeline. Whereas

programs that end some time after the range displayed by the timeline, are indicated by displaying

36

the end of the program at the very right hand edge of a timeline.

A full screen dialog with schedule timeline presents the user with two lists and an information

panel. The rightmost list displays all available services. The leftmost list displays schedule

information for each service shown in the rightmost list. The schedule information is shown as

timeline, each program is represented as a button that is scaled to indicate the program length

related to the time shown on the title bar. The user may navigate around the rightmost list to

highlight an individual program.

Program information for the highlighted program on the schedule is displayed in the

information panel.

The user may change the start time of the schedule information displayed for a

channel by either 30 minutes or an entire day. In addition, the user may also change the total time

shown by a schedule in 30 minute steps between 30 minutes and 3 hours, the default total time is 90

minutes. The feature to change the total time shown on a schedule is called zoom.

In the case when there is no schedule information available for a service, a blank timeline will

be shown, and the label “No Information Available” will be displayed when the service is

selected.

Please note that in this dialog a service must be deselected to enable Eclipse [1] to scan

each channel for schedule data.

The Extended Schedule Electronic Program Guide cannot be accessed if there are no

services available.

37

Timers or reminders cannot currently be set within this EPG.

Program Reminders

A program reminder provides functionality to remind the user a program has begun. When a

program reminder begins, a dialog is displayed offering the user the option to automatically

select the service that the reminder was set.

Within the Now and Next Electronic Program Guide a user may set a program reminder for any

“Next” program displayed.

Up to five program reminders may be set at any one time. Unlike timers, program reminders

do not persist when the DVB-T is reset.

• Timers

The user may set a timer to select a service for a period of time. A dialog to set timers is

provided as an option on the “Main Menu”. The timer dialog will not allow conflicting timers to be

set. Timers may be set to be triggered once, daily, or weekly.

When setting a timer a password can be supplied to be used by the DVB-T when a service is

selected, so that the timer can override any parental rating control when it triggers.

When a timer is triggered, whilst in “normal viewing” operation, a dialog is displayed offering

the user the option to cancel the timer or automatically select the service for which the timer

has been set. Once a timer has completed the service will remain selected.

When a timer is triggered whilst in standby mode the service for which the tuner was set is

38

selected. At the end of a timer event the application will return to standby mode.

If the user attempts to change the service, enter the “Main Menu”, or view an Electronic

Program Guide whilst a timer is running, a dialog will be displayed asking the user if they

wish to cancel the timer.

Up to five program timers may be set at any one time.

The Favourites dialog cannot be accessed if there are no services available.

• Settings

There are three items in this menu: Configuration, Language and Installation.

Configuration

In this item user may set TV type, TV output, Receiver Upgrade and Parent Control options.

The TV type and TV output items refer to the above.

Receiver Upgrade

The DVB-T will search for an OAD software update at 0300 GMT each day whilst in standby

mode. A dialog will be displayed if an OAD has been detected informing the user that an

OAD is taking place.

The user may search for an OAD software update using an option on the menu:

Settings/Configuration/ Receiver Upgrade.

Parental Control

Parental control allows individual services, the “Main Menu”, and the Installation menu to

be protected by a password.

Parental control is setup using the configuration dialog in the “Main Menu”.

Individual services can be selected to be password protected using the channel list dialog.

When a service has been password protecting it is not possible to select that channel

anywhere within the DVB-T without entering the parental control password.

The default password for parental control is “0000”.

The current functionality of the DVB-T does not provide a factory reset “back door” for the

parental control password. The user may search for a parent control using an option on the

menu: Settings/Configuration/Parent Control.

Language

A languages dialog is provided as an option in which the user may set System, Audio and

39

Subtitle Language, here the user can set the preferred and the current language of both the

audio and subtitles.

By setting the current language the user can choose from the languages available for a

particular selected service. Here, only the languages available for the current service will be

offered as an option. The preferred audio and subtitle language can be set to “English”,

“Welsh”,“Gaelic”. “English” is the default-preferred language in the UK version.

It is not possible to determine exactly which audio language is currently selected as an audio source

may indicate that provides support for more than one language. The languages dialog also displays

the current system language. The system language refers to the language used for all UI text

throughout the application. The default system language is set to “English”. The current language can

also be set from the Current Service Banner when you press the left key. When multiple language

options are available for either subtitles or audio on the current event the icon ”I/II” will be displayed on

the Current Service Banner. The user can then press the left key to display a dialog and set the

current audio or subtitle language for that service. The dialog will not be displayed if there are no

current language options available.

Installation Automatic Search

Automatic search is the ability to scan each channel for services. Automatic search can be triggered

on “First Time Installation” and using an option on the “Main Menu”. Whilst performing an automatic

search no service will be selected. A dialog is displayed during Automatic search that shows the

progress of the scan through the channels. The user, in such cases the previous list of services is

used, may cancel Automatic search. When an automatic search is complete the application will

attempt to select the previously selected service and return to “normal viewing” operation. In cases

were there was not a previously selected service the application will attempt to select the service with

the lowest RSN. The channels scanned during Automatic search can support up to 100 Services at

any one time.

Manual Search

Manual search allows the user to scan an individual channel for services. The user can perform a

manual search by selecting an option on the “Main Menu”. Whilst performing a manual search no

service will be selected. The user enters the channel number to be scanned; only those channels

supported by the tuner may be entered. The Manual Search dialog displays a bar indicating the

strength of the signal of the currently selected channel. The user can then choose to scan the

selected channel for services; a separate dialog is displayed showing the services found whilst

scanning are taking place. Newly discovered services are merged with the current list of services. The

user, in such cases, may cancel manual Search any newly discovered services are disregarded.

When a manual search is complete the application will attempt to select the previously selected

service and return to “normal viewing” operation. In cases were there was not a previously selected

service the application will attempt to select the service with the lowest RSN. The DVB-T can support

40

up to 100 Services at any one time.
