Remote Control and Receiver-Transceiver Specifications and Requirements

for Windows Media Center in Windows Operating Systems

Introduction

This document provides the information needed to design a remote control and receiver that will

work with those versions of Windows 7 that include Windows Media Center. This document

describes the requirements for a remote control, the remote control functions that must be

supported, the hardware specifications, and the infrared (IR) protocol requirements. This

document also describes in depth the different options that are available for building a receiver

that converts the commands from the remote control into actions for Windows Media Center.

What’s New

General

 Combined the Remote Control Specifications and Receiver/Transceiver Specifications

documents into one document for convenience.

 Changed the Power button label to Sleep throughout the document to accurately reflect the

functionality of this remote control button.

 Removed the option for Green Button remote controls from Windows 7 Home Basic.

Remote Control Updates

 Added an option to support the Microsoft Quatro Pulse remote control IR protocol.

 Added support for the optional buttons for ISDB markets: 10, 11, 12, Audio Select, Logical

Chanel Input, and Network Select.

 Added the option to use the "moon" icon for the Sleep button (formally the Power button).

 Updated the label for the "*" button to include a "." ("*/.")

 Updated the icon for the More Information button to add a circle around the "I".

 Added clarification for the ordering of the color buttons for ISDB markets.

 Updated the "TV standards and Windows Media Center Remote Controls" section, which

describes the types of buttons that can be distributed in different regions.

 Updated to have the option to remove the text labels above the number pad buttons.

Receiver/Transceiver Updates

 Added an "Overview of IR Receiver Options" section to help OEM partners understand the

options for building Windows Media Center remote control receivers.

 Updated requirements to support the Microsoft Quatro Pulse remote control IR protocol, as

follows:

Receivers must wake the system from both Microsoft RC-6 and Microsoft Quatro Pulse IR

protocols.

 Updated the Port Driver specifications to include the version 2 Device Driver Interface (version 2

DDI), as follows:

 The version 2 DDI adds robust reporting of hardware capabilities so that Windows Media

Center UI can appropriately adjust based on what the hardware can support.

 Better support for programmability of the Sleep button.

 Added support for discrete sleep and wake keys, which may require emulator firmware updates.

 Added the HID descriptor used for producing HID events for reference.
