What is a port on TV?

In the context of television, a "port" refers to a physical connector on a TV's back or side panel that allows you to connect external devices. These ports enable the TV to receive audio and/or video signals from sources like:

* HDMI（高解像度マルチメディアインターフェイス）： The most common port for high-definition video and audio. Many TVs have multiple HDMI ports to accommodate various devices.

* usb（ユニバーサルシリアルバス）： Used for connecting devices like flash drives, hard drives, and some cameras to play media files directly on the TV.

* Optical (Toslink): Used for transmitting digital audio signals to a surround sound system.

* Composite/Component Video: Older analog video standards, less common on modern TVs.

* Ethernet (RJ45): For connecting the TV directly to a wired internet network.

* RF Coaxial: For connecting an antenna or cable TV service.

* Headphone Jack (3.5mm): For connecting headphones to privately listen to audio from the TV.

The specific ports available will vary depending on the TV's model and features.
