HDMI中CEC的14个功能

HDMI中的CEC有14个功能(OPTIONAL),在你们设计的产品中用了哪些功能?

CEC 3 Feature Overview

CEC provides a number of recommended features designed to enhance the functionality and interoperability of devices within an HDMI system. This section gives an overview of these features.

• One Touch Play - Allows a device to be played and become the active source with a single button press.

• System Standby - Enables the user to switch all devices to standby with one button press.

• Preset Transfer - Enables any tuner device to download the same set of presets as the TV. It is used to auto configure a devices presets so no manual setup is required.

• One Touch Record - Offers a What You See Is What You Record (WYSIWYR) facility, meaning that whatever is shown on the TV screen is recorded on a selected recording device.

• Timer Programming - Allows a device (e.g. the TV) to set a timer recording on a recording device.

• System Information - Queries the system to determine device addresses and configurations (e.g. language and country)

• Deck Control - Enables a device to control (e.g. play, fast forward etc.) and interrogate a playback device (a deck).

• Tuner Control - Allows a device to control the tuner of another device.

• Vendor Specific Commands - Allows a set of vendor-defined commands to be used between devices of that vendor.

• OSD Display - Enables a device to use the on-screen display of the TV to display text strings.

• Device Menu Control - Enables a device to control the menu of another device by passing through user interface commands.

• Routing Control - Allows the control of CEC Switches for streaming of a new source device.

• Remote Control Pass Through - Enables remote control commands to be passed through to other devices within the system.

• Device OSD Name Transfer - Enables devices to upload their preferred OSD name to the TV. The TV can then use this name in any menus associated with that device.
