Preparation

Display & IR Controller

Prepare your purchased display and remote controller.

Web browser
(e.g. Google Chrome)

Use a web browser on your computer to open the dedicated tool display_control.html or Chrome DevTools.

Local network environment

Connect to the same network. Both wired and wireless LANs are supported.

It is helpful to record the display’s IP address in advance.
Procedure: [Settings]→[Network ＆Internet]→[Local network setup]

How to Use

Getting Started

display_control.html

1.How to try using display_control.html

How to Try Using display_control.html

This section explains how to use display_control.html to send IP control commands in a computer web browser, with an example to illustrate the process.

1.Required Display Settings for Trial

Check and record the display’s IP address.
Procedure: [Settings] → [Network & Internet] → [Local network setup]

Enable [Pre-Shared Key] in [Authentication] and set the Pre-Shared Key to “1234”
Procedure: [Settings] → [Network & Internet] → [Local network setup] → [IP control] → [Authentication]
See details

Switch to HDMI 1 input
Select [HDMI 1] using the remote controller’s [Input].

The following explanation assumes [HDMI 1] for smooth trial operation.

2.Control Execution

Open display_control.html in your computer browser and enter the following:
Display IP: The display’s IP address you recorded.
PSK: Pre-Shared Key (the “1234” you temporarily set on the display)

Figure of the Pre-prepared State
Prepared state

Select [HDMI 2] in the [Input] field and click [Go]. The display input switches from HDMI 1 to HDMI 2.

JSON-RPC Communication Example for Trial

The following JSON-RPC formatted request and response are exchanged between the display and the computer.

Example for Request (Computer → Display)

HTTP
POST /sony/avContent HTTP/1.1 
HOST: 192.168.0.1
 X-Auth-PSK: 1234 
Content-Type: application/json; charset=UTF-8 
{ method: "setPlayContent", 
version: "1.0", id: 1, 
params: [{uri: "extInput:hdmi?port=2"}]
 }

Example for Response (Display → Computer)

JSON
// HTTP 200 
OK { "result":[],
 "id": 1
}

2.How to check communication using Chrome DevTools

How to Run a Trial Using Chrome DevTools

As an alternative to display_control.html, you can also use Google Chrome DevTools. Send REST API commands using the following JavaScript sample.

JavaScript
var xhr = new XMLHttpRequest();
 xhr.open('POST', 'http://192.168.0.1/sony/avContent');
 xhr.setRequestHeader('X-Auth-PSK', '1234'); 
xhr.send(JSON.stringify( 
{method: "setPlayContent", 
version: "1.0", 
id: 1, 
params: [{uri: "extInput:hdmi?port=2"}]} 
));

Display Settings Required for Full REST API Use

1.Required display settings for REST API execution

Set the Authentication Method (Pre-Shared Key) and Level

To configure display authentication based on client authentication level, use [IP Control Authentication] in the Monitor settings. Enabling [Pre-Shared Key] allows access to private and generic level APIs.

Procedure: [Settings] → [Network & Internet] → [Local network setup] → [IP control]
The key can be set under [Pre-Shared Key]. Any character string can be used as the Pre-Shared Key.
See details

BZ40P / BZ35P / BZ30P

Other models

Enable Remote Device Control

Procedure: [Settings] → [Network & Internet] → [Remote device settings]→[Control remotely]

Disable Suspend

You can also address suspend state limitations by using the REST API.
See details

Recovery from Suspend State

If the display enters Suspend state unintentionally, the HTTP server stops, making REST API communication unavailable. In this case, enable the Wake-on-LAN (WoL: remote startup via network) feature to restore power to the display.

Required Display settings

Enable Wake-on-LAN
Procedure: [Settings]→[Network & Internet]→[Remote device settings]→[Control remotely]

Recovery from Suspend State via Wake-on-LAN
  1. Obtain MAC Address
    WoL magic packets must be sent to the MAC address of the target device. Call “getSystemInformation” to retrieve the display’s MAC address.
  2. Create WoL Magic Packet
    A WoL magic packet is a UDP packet consisting of “FF FF FF FF FF FF” + the MAC address repeated 16 times. Generate based on the display’s MAC address.
  3. Send Magic Packet
    Send multiple magic packets over UDP port 9 or 7 to the broadcast address of the target display on the network. Send multiple times to ensure reliable activation of the display.
  4. Wait for Power ON State
    After sending the magic packet, wait until REST API communication becomes available.
  5. Turn On the Display Screen
    “Normal Mode” Environment: After power ON, you must additionally use setPowerStatus to switch to the screen display state.
    “Pro Mode” Environment: The screen automatically turns ON.
  6. Execute REST API Control
    Once communication is available, use REST API to control power, input, and other functions.

2.Client settings (REST API authentication and communication parameter transmission)

Pre-Shared Key

The Pre-Shared Key must be included to the HTTP request to the REST API as a custom header named “X-Auth-PSK.”

Example for X-Auth-PSK Header (Pre-Shared Key: 1234)

HTTP
httpPOST /sony/system HTTP/1.1
Host: 192.168.1.100:80
Content-Type: application/json
X-Auth-PSK: 1234
Content-Length: 65
