2. INTRO

Congratulations on purchasing the MV7470. You now own a high quality, "Home" DVB-T HD modulator. To get the most out of your purchase, please take the time to carefully read through this manual

3. INSTRUCTIONS

3.1 DESCRIPTION

The MV7470 is a high quality DVB-T "Home" modulator which accepts one HDMI and converts it into one RF DVB-T channel on its output. The excellent picture (Full HD 1920*1080-30p) and modulation quality (MER\~35dB) renders the MV7470 the ideal solution for distributing SD/HD digital signals coming from e.g. a DVD player, STB or camera in a CATV network using the DVB-T technology.

The user has the ability to control the device by either using the onboard SSD (Seven Segment Display) interface and keypad for quick installation or by using the USB interface with the appropriate software accompanying the MV7470 for advance programming.

Finally, the MV7470 metal case provides excellent electromagnetic shielding as well as great temperature dissipation and rigidity.

3.2 FEATURES

• High quality and performance
• Very clean RF spectrum
• MER value \~ 35dB
• RF output frequencies 174...862MHz
  • H.264 HD encoder bitrate 1-19Mbps
• HDCP support (ON / OFF selectable)
• Very friendly user interface for quick installation
• USB interface for advanced programming
• External power supply

3.2.1 Auto-reset functions and watchdog

During the normal operation of the MV7470, the main CPU monitors all the internal parts in order to ensure that the device works normally. In case of an internal error or module failure, the MV7470 immediately initiates the recovery procedure by resetting the appropriate module or the device. Finally, watchdog timers ensure that the device will be reset in case of CPU failure.

3.2.2 Buttons lock-mechanism

The MV7470 will lock the functionality of its buttons after 5 minutes idle time to avoid of being pushed accidentally. Two red dots on the SSD notify the user that the button interface is locked. To unlock it, the user must press simultaneously the UP + DOWN buttons for 5 seconds approximately.

3.2.3 Digital attenuator

The MV7470 has an embedded digital attenuator. The user is able to select between three different attenuation steps as follows:

1. 0 dB attenuation (Output level: 90dbμV) SSD will display: "00"
2. 10 dB attenuation (Output level: 80dbμV) SSD will display: "10"
3. 25 dB attenuation (Output level: 65dbμV) SSD will display: "25"

3.2.4 HDCP ON/OFF function

By pressing the "Channel / Profile" button for more than 5sec the user enables the HDCP ON/OFF function. The SSD will display this status as follows:

1. H1 : Indicating that the HDCP is ON
2. H0: Indicating that the HDCP is OFF

Using the Up/Down buttons the user is able to select one of the above status to enable/disable the HDCP function. The MV7470 will exit from the current functionality after being idle for more than 2-3sec.

3.2.5 USB interface for advance programming

The MV7470 provides a USB interface with the appropriate software for advanced programming. For more information please read Appendix A.

3.3 INSTALLATION

The MV7470 can be programmed with one of the following ways:

• From the front panel display
• From the USB interface

3.3.1 Installation using the Front panel display

The user is able to install very quick and easy multiple MV7470s using the SSD + Button interface of the front panel of the device, following the steps below:

1st Step

Power up the MV7470 by adding the external power supply. The MV7470 will need 20-30 secs to initialize itself. The SSD (Seven Segment Display - No2 / Figure No.1) depicts the initialization status.

2nd Step

Choose "Chanel mode" by pressing the Channel/Profile button (No 1 / Figure No.1) and the "Channel LED" will lit indicating that "Channel" selection mode is selected.

3rd Step

Choose "Attenuation mode" by pressing the Channel/Profile button (No 1 / Figure No.1) the "Attenuation LED" will lit indicating that "Attenuation" selection mode is selected.

4th Step

Choose "Profile mode" by pressing the Channel/Profile button (No 1 / Figure No.1) and the "Profile LED" will lit indicating that "Profile" selection mode is selected.

How Profiles works

In an installation all the modulators (or Mux in general) need to have different values of the following fields to avoid conflicts in the automated scan of the TV sets:

Program Name Service ID TS ID

For that reason, the user must always selects a different Profile number in every modulator starting from Number #1.

Eg. Let's say we want to install three modulators in a CATV network. In step No 4 we will choose:

- Profile 1 for the 1st modulator

- meaning: Program Name = DTV 1

- meaning: Service ID = 1

- meaning: TS ID = 2210

• Profile 2 for the 2nd modulator
• meaning: Program Name = DTV 2
• meaning: Service ID = 2
• meaning: TS ID = 2211

- Profile 3 for the 3rd modulator

- meaning: Program Name = DTV 3

- meaning: Service ID = 3

- meaning: TS ID = 2212

As a result, all the above modulators have different values in the above fields.

Caution!!!

• Every time we choose a different Profile number the MV7470 will apply a full reset to itself that will last for 20-30 seconds.
• Using the USB interface, someone has the ability to add custom values to the above fields.
• Depending on the video/audio format in the HDMI input, switching HDCP mode may be necessary (section 3.2.4).

3.3.2 Installation using the USB interface

The MV7470 provides a USB interface with the appropriate software for advanced programming. For more information please read Appendix A.

4. DVB-T Settings - Parameters regarding the modulator part

5. Encoder Settings – Parameters regarding the H.264 encoder
6. Multiplexer Settings - Parameters regarding the multiplex part
7. System Settings – Parameters regarding system information

1. DVB-T Settings

In this category the user is able to adjust several parameters of the modulator RF output part, as described below:

1.1 Channel - Output channel selection (VHF:5-12 & UHF:21-69)

1.2 Bandwidth - Bandwidth selection
1.3 Constellation - Constellation selection

1.4 Modulation - Modulation selection

1.5 Guard Interval - Guard Interval selection

1.6 Code rate - Code rate selection

2. Encoder Settings

In this category the user is able to adjust parameters of the H.264 encoder, as described below:

2.1 Input source - Select the primary input source
2.2 Video BR (Mpbs) - Set the video bitrate

2.3 Audio BR (Kbps) - Set the audio bitrate

2.4 Audio Encoding - Select the audio encoding
2.5 HDCP ON/OFF - Enables/disables HDCP

3. Multiplexer Settings

In this category the user is able to adjust parameters of the MV7470 multiplexer, as described below:

3.1 Network Name + ID - Enter the Network name + ID*

3.2 Program Name + ID - Enter the Program name + ID

3.3 Provider Name - Enter the Provider name

3.4 Original Net ID - Set the Net ID (0-65535)*

3.5 TS ID - Set the Transport Stream ID (0-65535)*

3.6 PMT PID - Set the PID value

3.7 Video PID - Set the Video PID value

3.8 Audio PID - Set the Audio PID value

3.9 LCN No - Set the LCN No (1-999) (must be enabled first)

3.10 LCN Provider - Set the LCN provider

* TS ID must always be different between DVB-T modulators in the same network.

Caution!!!

- Modulation settings must be applied with care and in order to have adequate output bitrate. The output bitrate (which can be calculated from the tables in Appendix B) must be equal or greater than the total sum of the bitrate of the encoders.

Example: Assuming we select the following modulation settings:

Modulation: 8K

Constellation: 16-QAM

Code Rate: 5/6

Guard Interval: 1/32

Bandwidth: 8MHz

We have an output bitrate of 20.107 Mbps according to Appendix B.

This means that encoder's bitrate must be adjusted in such a way that the total bitrate of the encoder does not exceed the 20.107 MBps limit, otherwise artifacts may occur.

For example, one valid selection in case of four encoders would be to set each encoder bitrate to 5Mbps since: 4 × 5 bps = 20Mbps < 20.107MBps
