1. Introduction The STB’s that operate on the South African Digital Terrestrial network shall contain two types of software that provides the software functionality of the STB. The first type of software is the MHEG application/s which will be delivered by the FTA broadcasters. The second type of software is the embedded native code, implemented by STB manufacturers, that supports the STB functionality as well as provides some of the user interface screens. This specification outlines the basic functional requirements for the native user interface (“Native UI”) screens that are embedded in the STB and is to be read in conjunction with the Set Top Box specification SANS 862. Areas of native code functionality that pertain to key support services (such as call centre) have been prescribed as mandatory. Menu and submenu structures, menu item numbers and dedicated keys as defined in this document are all mandatory requirements. STB manufacturers are able to exercise their own options in terms of the following items: • Screen colours • Graphics design • Support additional STB features • Include menu options in addition to those prescribed in this document. Screen examples containing the minimum menus structures have been provided for explanatory purposes but are not prescriptive in terms of colours and graphic design. Certain of the user interface functions and screens will be provided by the MHEG Guide applications. These applications will be broadcast by means of MHEG data carousels by the broadcasters and will be stored in the STB flash memory. The Guide applications will therefore mostly be accessed by means of the MHEG File System Acceleration from the STB flash memory to provide a quick access time. These applications may be updated from time to time at the FTA broadcasters’ discretion and therefore the STB manufacturer has no control over these aspects of the STB operation. The minimum set of Guide Applications and supporting documentation shall be supplied to STB vendors to be incorporated into their STB’s prior to manufacture. The Guide applications include the following key functions and screens: 1. Electronic Programme Guide (“EPG”) – which is a full seven day programme guide using EIT based data 2. Now/Next banner – (also known as the channel change banner, or small/large information screens) which provides programme information on the Now channel selected as well as the Next event on that channel 3. Channel List – which provides a list of available channels ( Radio and TV )

2. Launch Applications The Launch Applications provide the user with all programme related information and therefore needs to be always accessible to the user. To achieve this functionality with an MHEG application, the STB shall be able to run the Launch Applications directly from the File System Acceleration (FSA) cache without having to follow the boot process described in section 9.3 (the PMT and Service Gateway signalling extension ) of the MHEG specification. This implies that the Launch Applications will not need to be signalled in the PMT and therefore the Launch Applications shall be able to display even if no PMT is present.
Requirement 2.1 followed:
Whenever the embedded native code is requested to display a Launch Application, the following procedure shall be
1. If another MHEG application is running, it shall first be terminated. 2. If the Launch Application has not yet been loaded into the FSA, the application shall first download into the FSA cache. An example of this is after a factory reset has been initiated. The time for the Launch Application to display is determined by the broadcast system play out rate of the application. 3. If the Launch Application is resident in the FSA, the STB shall launch the requested Launch Application (from cache as described above) using the corresponding URL as shown in the table below. Launch application Electronic Program Guide Now/Next Banner Channel List
URI DSM://navigator/epg DSM://navigator/info DSM://navigator/slist
The time for the Launch Application to display shall be less than 1s. Requirement 2.2 The embedded native code and its associated User Interface shall not display any programme related information that performs the functions of, or replicates, an embedded EPG, now/next banner or in service channel list. The Native UI shall not cause contention or conflicts with the functions provided by the Launch Applications.
Confidential
Page 8 of 33
3. On-screen display requirements Requirement 3.1 The native UI screens must be designed for use on 4:3 CRT Televisions taking into account best practice with regards to safe areas. Downscaling may be used, but not at the expense of screen clarity. If a native 720x576 resolution screen looks better then it shall be used. If a 16:9 screen is configured or detected (e.g. an HDMI display is connected) then a higher resolution screen that covers the entire video plane may be used. Requirement 3.2 The Tiresias screen font shall be used as it has been designed for legibility on a television. If need be, an Anti-aliased version of it scales very well to different resolutions. The Tiresias font will also be used on the MHEG application screens thereby ensuring a similar look and feel when moving from native to MHEG screens. Mixed case letters shall be used. Oblique, italic, underlined and condensed fonts are not acceptable. Requirement 3.3 The UI should be designed using the principles of good web design practice (Reading through the W3C guidelines at http://www.w3.org/ is recommended) especially when moving around menus where the use of clear and understandable menu terminology shall be used as well as the current menu option being highlighted clearly. Requirement 3.4 Items that are mandatory in the menus shall be numbered and directly selectable using numeric keys. This aids any call centre trying to provide telephonic assistance. Requirement 3.5
An unambiguous correspondence between the on-screen prompts and labels on the remote control shall be used.
Requirement 3.6 Text, relevant symbols and icons shall be displayed with good contrast taking into account that the UI needs to be readily viewable on a monochrome screen avoiding the ambiguity that could arise by using similar colours. Combinations of red and green as well as pure red and white combinations should be avoided. Requirement 3.7 standards.
Only Arabic numbers shall be used (1, 2, 3…) and symbols and icons should assent to internationally recognised
Requirement 3.8
Left-aligned text shall be used rather than centred or right-aligned. Justified text for paragraphs should be avoided.
Confidential
Page 9 of 33 Requirement 3.9 The display of signal strength indicator (SSI) and signal quality indicator (SQI) as defined, shall include an on screen display or bar that is colour coded to indicate signal conditions that are within tolerance, marginal and out of tolerance. The display shall always be supported by a text description that indicates that the signal is: -
“Ok” and green if signal level is acceptable “Weak” and amber if signal level is marginal “Poor” and red if signal level is unacceptable
4. General interaction Requirement 4.1 Certain RCU keys have global and uniquely assigned functionality in the native embedded code and applications. That is, the designated function shall occur irrespective of which screen or menu the user is using. These keys are: -
Power, Exit
Requirement 4.2 In addition, there are further keys that will perform a unique designated function in all native embedded code – these keys are not to be used as soft keys for a secondary function. These keys are: -
Vol+, Vol-,CH+,CH-,Info, EPG, Menu, Back, Mute
Requirement 4.3
The UI shall provide a direct way of returning to the previous user menu through the use of a “back” button.
Requirement 4.4
The “exit” button will always result in the exit of any application or UI and reverts to the previously selected service.
Confidential
Page 10 of 33
5. Receiver response The UI shall provide direct and clear feedback for any action initiated by a user (e.g. selecting a highlighted option or moving through options in a menu etc.) If any user initiated action results in a noticeable delay then the receiver shall provide suitable feedback to assure the user that the action has been accepted. Requirement 5.1 If it is a short delay (longer than 3s but less than 10s ) then a simple message such as “Please Wait” or something more appropriate to the action should be displayed. Requirement 5.2 If it is a long delay (more than 10s) then more detail is required; such as by providing a progress bar or other visual indication to indicate when the STB may finish the requested action.

Operation
Requirement 8.4.3.1.1 It shall be possible to apply parental control on individual events and complete channels. Parental control for individual channels shall be implemented as part of the channel store and preferences function. Requirement 8.4.3.1.2 The parental control function for an event or channel shall be controlled by the parental rating contained in the EPG (SI, EIT information). The STB decoder shall suppress both video and audio if the parental rating is above the configuration threshold for the event. Unblocking of a parentally blocked event shall be done through the entering of a parental PIN. Once the event has been unblocked, it shall remain unblocked for the duration of the event. A change away from the channel and back again shall not require PIN re-entry within the timescale of that event.
8.4.3.2
On-screen messages
Requirement 8.4.3.2.1 If the user has enabled parental control and the rating of the current event is above the trigger level, the STB decoder shall request the entry of a four-digit parental control PIN before allowing access to the event. Requirement 8.4.3.2.2 If an incorrect PIN is entered, the decoder shall generate an error message and request re-entry. Requirement 8.4.3.2.3 After five incorrect attempts, the decoder shall advise the user that no further attempts can be made for a period of 10 min. During this period, it shall be possible to select other services, put the decoder into standby, etc. However, these actions shall not reset the timer, and the error message shall be displayed whenever the user returns to that event.
When a higher rating is applied to an unblocked event, the unblocked event shall be blocked and the user will be required to re-enter the parental PIN. Checking of parental control status and subsequent content suppression, if appropriate, shall apply across all state transitions,

Software Updates
Requirement 8.4.4.1 A software update function shall be provided that allows software updates in two ways: •
•
Factory reset
“Automatic” where the STB will perform an update as scheduled by the broadcaster. The STB will therefore automatically load the update software as soon as it is broadcast. “Manual” where the STB shall perform an update initiated by the user. In this mode the UI must provide an indication to the user if the update is not available and if the update process has been successfully completed.
Requirement 8.4.4.2.2 The factory reset function shall also be triggered by a simultaneous pressing of the two channel change buttons on the STB front panel, i.e. without the need for an RCU.
8.4.4.3
