OPPO蓝光DVD-UDP203 IP控制代码是针对OPPO BDT-101CI蓝光播放器的一种远程控制机制，它允许通过网络连接的设备（如个人电脑或智能手机）来操作和管理OPPO蓝光播放器。这种功能的基础是IP控制协议，它定义了服务器（即OPPO蓝光播放器）与客户端（如网络设备）之间的通信规则。在OPPO的IP控制协议中，服务器角色的BDT-101CI蓝光播放器会周期性地广播UDP消息，每10秒一次，通知所有监听的客户端其可用性，包括IP地址、端口号以及服务器名称。客户端的任务是接收并解析这些广播消息，从中获取必要的信息，然后建立与服务器的TCP连接，并发送控制命令。广播消息的目标地址是：239.255.255.251:7624，消息格式如下： "Notify: OPPO Player Start Server IP: <服务器IP> Server Port: <服务器端口> Server Name: <服务器名称>" 例如： "Notify: OPPO Player Start Server IP: 192.168.0.2 Server Port: 23 Server Name: OPPO BDT-101CI" 一旦客户端接收到广播消息，它将使用其中的IP地址和端口号建立TCP连接。如果客户端已经建立了连接，它应该忽略后续的广播消息。TCP连接建立后，客户端就可以通过发送特定的控制命令来操作播放器的各种功能，如播放、暂停、快进、快退、音量控制等。在"CONNECT"阶段，客户端利用获取的IP地址和端口号通过TCP协议进行连接。如果连接成功，客户端就能发送预定义的控制指令到服务器，服务器接收到命令后执行相应的操作。TCP连接确保了数据传输的可靠性和顺序，适合于控制指令的传输。 "COMMAND"阶段，客户端发送的命令可能包括但不限于以下几种： - Power ON/OFF：开启或关闭播放器。 - Play/Pause/Stop：播放、暂停或停止当前媒体。 - Forward/Reverse：快进或快退。 - Chapter/Track Seek：跳转到特定章节或曲目。 - Volume Up/Down/Mute：调节音量或静音。 - Navigation：导航菜单和设置。 - Disc Eject/Load：弹出或加载光盘。这个IP控制协议为智能家居系统集成OPPO蓝光播放器提供了便利，用户可以通过智能设备实现对播放器的远程控制，增加了设备的易用性和自动化程度。在实际应用中，开发者或用户需要编写客户端应用程序，实现对上述协议的解析和命令的构建。这通常涉及到网络编程的知识，如UDP和TCP套接字编程，以及可能的JSON或XML格式的命令结构。此外，对于智能家居系统的集成，还需要了解相关智能家居平台的API和交互方式，以便将OPPO播放器无缝整合到整个家庭自动化系统中。

OPPO BDT-101CI Blu-ray Transport

IP Control Protocol

(Version 1.0, November 18, 2015)

Note: This document describes a preliminary version of the IP control protocol for OPPO

BDT-101CI Blu-ray transports. This feature allows a network-connected device such as

a PC or a smartphone to control the OPPO Blu-ray transport. The OPPO Blu-ray

transport functions as a Server, which broadcasts the message, waits and listens to the

port(s), responds to the client’s connection, receives the client’s commands, and

performs the action. The network device functions as a Client, which receives and

processes the broadcasting message, sets up the TCP connection with the Server, and

sends the control commands. In the remainder of this document, we use “Server” for

BDT-101CI Blu-ray transport and “Client” for the network device.

The complete client control procedure can be described in three sections: DISCOVER,

CONNECT and COMMAND.

1. DISCOVER

Once the Server is running, it will automatically broadcast the UDP message every 10

seconds to notify any interested Client about its availability, as well as the IP address,

the port number, and the Server’s name. The Client needs to receive this broadcasting

message, extract the IP address, port number, Server name, and establish the

connection with the Server. Once the connection is done, the Client should also discard

any future broadcasting messages.

The address used for the Server’s message broadcast is: 239.255.255.251:7624

The format of the broadcasting message is:

Notify: OPPO Player Start

Server IP:

Server Port:

Server Name:

For example:

Notify: OPPO Player Start

Server IP: 192.168.0.2

Server Port: 23

Server Name: OPPO BDT-101CI

2. CONNECT

The Client will use the IP address and port number extracted from the broadcasting

message to establish the TCP connection with the Server.

If the Client already knows the Server’s IP address, the Client can establish the

connection directly by using the Server’s IP address.

3. COMMAND

Once the connection is established between the Server and the Client, the Client can

send the commands to remotely control the Server.

Command Structure:

Each command starts with a # sign (ASCII 0x23), followed by a 3-character command

code. If there are any parameters for the command, the parameters are given in text

format, separated by a space (ASCII 0x20) from the command code. The #

character(ASCII 0x23) must never appear in the parameters. A carriage return (ASCII

0x0d) indicates the end of the command. A line feed (ASCII 0x0a) can optionally follow

the carriage return and will be ignored. Each command generally may not exceed 25

bytes including the start of the command and end of the command. (Certain special

commands may exceed the 25 bytes limit and will not be available via the RS232 control

port.)

The illustration of the command structure is as follows:

<Command> = <Start of Command><Command Code>[<sp><Parameters>]<End of

Command>

<Start of Command> = #, ASCII 0x23

<sp> = space, ASCII 0x20

<Parameters> = command-specific

<End of Command> = CR, ASCII 0x0d[LF, ASCII 0x0a]

Response Structure:

Upon receiving a command, the player will try to execute the command and send back a

response. The response starts with an “@” sign (ASCII 0x23), followed by the original

command code and a space (ASCII 0x20), and a result code, either “OK” or “ER”. If

there are any parameters or additional message, the parameters or message is given in

text format, separated by a space (ASCII 0x20) from the result code. The @ character

(ASCII 0x40) must never appear in the parameters or message. A carriage return (ASCII

0x0d) indicates the end of response. Each response generally may not exceed 25 bytes

including the start of the response and the end of the response. (Certain special

responses may exceed the 25 bytes limit and will not be available via the RS232 control

port.)

The illustration of the response structure is as follows:

[<sp><Parameters>]<End of Response>

<Start of Response> = @, ASCII 0x40

<Result Code> = OK|ER

<sp> = space, ASCII 0x20

<Parameters> = command-specific

<End of Response> = CR, ASCII 0x0d

Status Update Messages Structure:

If the verbose mode is set to 2 or 3, the player will send status update messages

automatically. These messages are not a response to any particular command. Any

status change caused by commands from IP or RS232 control, front panel buttons, IR

remote control, or playback progress may trigger status update messages.

The status update messages have the following structure:

<Start of Update> = @, ASCII 0x40

<sp> = space, ASCII 0x20

<Parameters> = status-specific

<End of Response> = CR, ASCII 0x0d

Command Sequence:

Commands are executed in the order they are received. The control client should wait

for a response from the player before sending the next command.

If the player receives a new command before executing the previous command, the

player may execute the commands in sequence or discard the previous command,

depending on the internal processing of the player. The control client should avoid

sending multiple commands in sequence without waiting for a response.

If the host does not receive a response from the player 10 seconds after the command is

issued, the host may consider the command or response lost during transmission, and

can retransmit the command.

Command List:

A. Command that maps to a remote control button

This group of commands maps directly to the infrared remote control keys. No

parameters are needed for these commands. The player handles the commands as if it

receives the same IR remote commands. For actions that require a multiple-key

sequence, such as go to a certain chapter (GOT command followed by multiple numeric

key commands and the SEL command), the player responds to each command

individually until the last command is received. At that time the player will respond with

either OK or ER depending on the result of the action.
