HDMI is an abbreviation of High-Definition Multimedia Interface, which is an AV digital interface that can be connected to a TV or amplifier.
With the HDMI connection, high definition video and high quality audio formats adopted by Blu-ray Disc players (Dolby Digital Plus, Dolby TrueHD, DTS-HD, DTS-HD Master Audio) can be transmitted, which is not possible with the analog video transmission.
Furthermore, in the HDMI connection, audio and video signals can be transmitted through a single HDMI cable, while in conventional connections it is necessary to provide audio and video cables separately for connection between devices. This allows you to simplify the wiring configuration that tends to be quite complex in a home theater system.
This unit supports the following HDMI functions.
An imaging technology supported by HDMI. Unlike RGB or YCbCr, which uses 8 bits (256 shades) per color, it can use 10 bits (1024 shades), 12 bits (4096 shades), or 16 bits (65536 shades) to produce colors in higher definition.
Both devices linked via HDMI must support Deep Color.
This function lets HDTVs display colors more accurately. It enables display with natural, vivid colors.
“x.v.Color” is trademark of Sony Corporation.
This unit supports input and output of 3D (3 dimensional) video signals of HDMI. To play back 3D video, you need a TV and player that provide support for the HDMI 3D function and a pair of 3D glasses.
4K / 8K
This unit supports input and output of 4K (3840 x 2160 pixels) and 8K (7680 x 4320 pixels) video signals of HDMI.
It automatically makes settings suitable for the video output type (content information).
Adobe RGB color, Adobe YCC601 color
The color space defined by Adobe Systems Inc. Because it is a wider color space than RGB, it can produce more vivid and natural images.
Each of these color spaces defines a palette of available colors that is larger than the traditional RGB color model.
ALLM (Auto Low Latency Mode)
This unit automatically switches to low latency mode depending on playback contents when using a combination of television and game console compatible with the ALLM function.
Auto Lip Sync
This function can automatically correct delay between the audio and video.
Use a TV that is compatible with the Auto Lip Sync function.
HDMI Pass Through
Even when the power to this unit is set to standby, signals input from the HDMI input connector are output to a TV or other device that is connected to the HDMI output connector.
If you connect the unit and an HDMI Control function compatible TV or player with an HDMI cable and then enable the HDMI Control function setting on each device, the devices will be able to control each other.
Power off link
This unit power off can be linked to the TV power off step.
Audio output destination switching
From the TV, you can switch whether to output audio from the TV or the AV amplifier.
You can adjust this unit’s volume in the TV volume adjustment operation.
Input source switching
You can switch this unit input sources through linkage to TV input switching.
When playing the player, this unit input source switches to the source for that player.
ARC (Audio Return Channel)
This function transmits audio signals from the TV to this unit through the HDMI cable and plays back the audio from the TV on this unit based on the HDMI Control function.
If a TV without the ARC function is connected via HDMI connections, video signals of the playback device connected to this unit are transmitted to the TV, but this unit can not play back the audio from the TV. If you want to enjoy surround audio for TV program, a separate audio cable connection is required.
In contrast, if a TV with the ARC function is connected via HDMI connections, no audio cable connection is required. Audio signals from the TV can be input to this unit through the HDMI cable between this unit and the TV. This function allows you to enjoy surround playback on this unit for the TV.
eARC (Enhanced Audio Return Channel)
The eARC function is an extension of the conventional ARC function. It utilizes dedicated eARC function control to play back television audio from this unit without passing through HDMI control. Furthermore, the eARC function can transmit multichannel linear PCM, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, DTS:X and other audio formats not compatible with conventional ARC. Connecting to an eARC function-compatible television also enables enjoyment of higher-quality surround playback of the audio content played from your television.
VRR (Variable Refresh Rate):
VRR reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
QMS (Quick Media Switching):
QMS for movies and video eliminates the delay that can result in blank screens before content is displayed.
QFT (Quick Frame Transport):
QFT reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.
