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 inimplementing

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 baseband 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.

Page 31 of 83

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 channel label 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 unmute 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, 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 –Portuguese-Off

For NTSC, CC1 – CC2 – CC3 – CC4 – Off The displayed CC option can be set either, it is set automatically

after two seconds.

ATSC+NTSC TV RF signal are separated into 2 way output when enter into Tuner. One is NTSC (Analog signal) that output video signal by mixing, amplifying, demodulating. Video signal are separated into Y/C signal throughTEA6415C, and transferred into ITU601 through ADV7401, then send into Video-audio process chip Generation9. Tuner output SIF audio signal to MSP3450G to process, amplify, then put in D-type amplifier TA2024.

The other ATSC (Digital signal, ATSC channel bandwidth is 6MHZ) via Tuner transferred into

TS-stream through 44MHZ intermediate frequency amplify, ASW filter, QAM\OFDM demodulate,

then enter into Generation-9 to MPEG decode, video part revert into video signal through coding, and transferred into double-field TTL signal by this chip process. Then put into Scaler and LVDS drive chip DS90C2501, through coding output 5 pair LVDS signal to drive PDP panel module. Digital audio signal from Generation-9 revert into Audio signal to MSP3450G through PCM decoding.

Program information in TS-stream be parsed and stored, user could know related program information through OSD query menu. For multi-program TS-stream, user could appoint to see some program in this stream through program guide EPG.

AV, S-video, YPBPR, DVI, D-Sub and each Audio signal through two group of 74HC4052 switch with ATSC audio signal together put into MSP3450G, through alt, woof, balance, volume, SRS, BEE process, then amplify by D power amplifier TA2024,output to loud-speaker.
