What is Audio Return Channel(ARC)and CEC

Audio Return Channel (ARC) is a feature of HDMI technology that allows audio to be sent from a television to an audio device, such as a sound bar or home theater receiver, over the same HDMI cable already being used to send audio and video to the television. This allows the user to hear sound from the television through a connected audio device, even if the television itself does not have integrated speakers. Audio Source with ARC channel like Smart-TV Apps like Netflix / Hulu or Tuned Over-the-Air Channels. It is important to note that both devices in this signal chain (Smart TV & Audio System) must have ARC capable HDMI input and output ports. These ARC capable ports will be labeled specifically for this function.  If you do not have an ARC capable sound system, you can use the HDMI Audio extractor with ARC function , to extract the audio from your TV and output the audio signal via SPDIF or 3.5 mm analog audio to your sound system. ***Please note that when you’re using the ARC function of HDMI, both your TV and your Sound System device must have CEC enabled.*** What is CEC CEC stands for Consumer Electronics Control and is an HDMI feature that allows devices to control each other when connected through the HDMI connection. It enables a single remote control to operate multiple devices and enables the devices to transmit information to each other. An example of the CEC power and Input feature would be allowing your DVD

What is EDID for HDMI distribution products?

What is EDID ? EDID pass-through refers to a play-back device that can read the display device’s information,such as resolution, factory model, date of manufacturer, and so on. The Benefit of EDID pass-through is the player can read the resolution of the display device directly so that the video signals that the display device can accept can be output in the best effect. TCL in the figure means TCL TV, TOS is short for TOSHIBA, that is, this product can reach the EDID information of the display device perfectly. The product supports EDID unvarnished transmission. The EDID information of the display device will be automatically read and supplied to the signal source after powering on or replacing the display device, This will result in better device compatibility. What is EDID Mix? As a TV with a different model and resolution, it reads the TV’s resolution ratio before the splitter/switcher/matrix/extender transmits data to the TV, automatically chooses a suitable resolution ratio, then sends data out.
