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.
