8、Software Platform Reference TV Application
8-1 Introduction
This document describes Phobos’s reference TV application, supporting the basic control functionalities
required to watch television. The reference application is designed to assist Phobos customers in implementing
a DTV system, using the Generation9-Elite IC and its APIs. This reference application is intended to support
U.S. based terrestrial analog/digital broadcasting(NTSC/ATSC), and includes Electronic Program Guide
(EPG), closed captioning, and parental control, as well as basic TV controls and underlying A/V decoding. The
reference TV application layer lies on top of Phobos’s Cougar API middleware that provides the
Transport/Audio/Video/graphics driver functionalities as a chip-independent set of APIs.
8-1-1 Supported Functions
The supported application functions are:
• Power control
• Source selection
• Channel change (up/down, recall and direct digit key input)
• Volume and mute control
• Closed caption selection
• Electronic program guide
• Menus: audio, video, setup, feature
8-2 The Phobos Reference TV Application
This chapter describes basic TV controls such as channel changing, source selection, and mute/volume control.
These basic functionalities are made available through the combination of GUI and standardized TV APIs. The
application also utilizes the results of PSIP parsing and decoding of EIA708/608 data. These are used to
support closed captioning and parental control, both of which are required on television sets sold within the
U.S.
In addition to Tuner, AV Input and Channel Map APIs, the reference application uses a set of Control
Array APIs to control the hardware blocks. These provide a standardized way to control the various hardware
blocks in the TV chassis.
8-2-1 Power Control
The current reference application does not support standby power control as part of this
implementation. Instead, pressing the power button on the remote and front panel controls the display and
audio outputs only. A power-on configures the system based on Control Array values stored in non-volatile
memory.
8-2-2 Source Selection
The Reference platform has analog/digital base band inputs as well as transport input through ATSC digital
channel. The TV/Input button cycles through the input sources:
1. RF
2. Front Composite (shared with S-video)
3. Rear Composite (shared with S-video)
4. YPbPr Component 1
5. YPbPr Component 2
6. VGA
7. HDMI input
The displayed banner for changing source is the same as the channel banner, except for displaying source
number and name.
31
Page 32
8-2-3 Channel Change
There are three ways to select a channel in the reference TV application: channel up/down, digital, and last
buttons in remote controller.
• Pressing the channel up or down key tunes to the next highest or lowest channel in the selected channel
map; a channel in a different channel group (analog or digital) is tuned at the limits of the available scan.
The channel map is established through the Auto Program menu, which automatically removes any no
signal channels. After channel scanning, the channels are grouped as digital channels and analog
channels.
• For digital channels, the channels are sorted on the virtual channel number. Further manual editing of the
channel list can be done through the Manual Channel Set menu. If no channels are enabled in the
selected channel map after initial power on, then the channel up/down keys select the channel number
next to the current channel, and determine the analog or digital channel based on the availability of
signal.
• Channels can be directly accessed by pressing the digit keys on the remote controller. The channel
selected is tuned immediately if the OK key is pressed, or will be tuned automatically after two seconds
of inactivity following the last entered digit. If the entered digit keys starts with a zero (“0”), the channel
number will be tuned to the second digit (for instance, the digits 03, entered in sequence, will tune
immediately to channel 3). Any channel may be selected by this method, regardless of its presence or
absence in the current channel map.
• Pressing the Last key in the remote control tunes the channel selected prior to the currently tuned
channel. For ATSC channels, it selects the sub-program number as well as the channel number.
The above channel-change operations are implemented via the Tuner and Channel Map APIs.
After tuning, the application displays the information of the currently-tuned channel. This includes:
1. Channel number [Ch 9-1]
2. Channel Label [for instance, KQED]
3. Current Time [for instance, 12:30 PM]
4. Rating information [for instance, TV-PG]
The virtual channel number will be displayed if the current channel is digital. The chann el la bel is extracted
from input signal if there is no label setting for the current channel. The channel label can be explicitly set with
Channel Labels menu, which will use TLChMapSetChannelName to store the label.
8-2-4 Volume and Mute Control
Pressing the volume Up or Down button changes the current volume in the Control Array and applies this
change to the hardware block. The range of control is determined by the Control Array; the current
implementation has a range from 0 to 63. Pressing either of the volume keys clears the mute audio mode of
operation, if previously set. If no button is pressed for five seconds after pressing the last volume Up or Down
button, the volume display will be automatically removed.
The reference application supports audio mute or un-mute by pressing the Mute key. When mute is enabled,
the audio is muted, displaying an icon on upper right side. The mute condition is cleared when the TV is
powered off.
Pressing the Mute key invokes the mute icon on the right corner of screen.
8-2-5 Closed Caption Selection
This section describes how to enable Closed Caption (CC) on the Phobos TV application. When the TV
is switched ON, captions are disabled by default. The user switches captions ON using the [SUBTITLE] key
on the remote. Each time the [SUBTITLE] key is pressed, a new language/CC option, is displayed near
the bottom center of the display. The sequence of options available are listed below
(depending upon the stream type — ATSC/NTSC).
For ATSC, English – Spanish – French – Off For NTSC, CC1 – CC2 – CC3 – CC4 – Off The displayed CC
option can be set either by the user pressing the [OK] key on remote, or else it is set automatically after two
32
Page 33
seconds.
8-2-6 Navigating a Menu
Pressing the Menu button displays the most-recently-used menu. The main menu is presented in two areas: a
group of icons, and a list of sub-menus based on the selected icon. After launching the menu, the Left/Right
buttons are used to select one of the two areas. The icons and sub-menus can then be navigated through the
Up/Down arrow keys, which moves the highlighted item up or down, depending on the key pressed. This
display gives the user a method of selecting among the various sub-menus available, in order to co nfig ure the
system.
The action wraps from first to last when an up arrow is received and the first list item is highlighted, and from
the last to the first when a down arrow is received and the last list item is highlighted. If no key is pressed for
one minute after pressing the last navigation or OK buttons, the volume display will be automatically
removed.
