What's the difference between MHL cable and HDMI cable?

MHL cable and hdmi cable are independent, but inseparable from each other. The interface of MHL line outputs hdmi signal, which needs to be used to connect mobile phones and devices.

1, MHL cable is an audio-visual standard interface for connecting portable consumer electronic devices. MHL cable can be presented on HDTV through standard HDMI cable input interface. Generally used in mobile phones, the MICROUSB port on the mobile phone is connected to the HDMI cable through the conversion cable, thus connecting the mobile phone to the TV or display.

2. It uses the existing Micro USB interface, whether it is a mobile phone, a digital camera, a digital video camera or a portable multimedia player, it can directly transmit the complete media content to the TV without destroying the high-resolution effect of the film.

3. The relationship between 3.MHL line and HDMI line requires relevant patch cords.

4.HDMI cable is just a kind of video transmission line. At present, some main game consoles such as wii,? XBOX360？ And Sony's PS3 HDMI input function.

5. Both ends of HDMI are HDMI interfaces, but the models are different. MHL is an HDMI, and the other end is a micro USB. Just like the data cable of a mobile phone, if both the mobile phone and the TV support the MHL function, only one MHL cable is needed for transmission. If the TV (or monitor) does not support it, a converter is needed to transmit HDMI.

Extended data:

1, HDMI cable is the abbreviation of high-definition multimedia interface cable, which can transmit uncompressed high-definition video and multi-channel audio data with a maximum data transmission speed of 5Gbps.

2. At the same time, there is no need for line/analog or analog/digital conversion before signal transmission, which can ensure the highest quality audio-visual signal transmission.

3. The 3.HDMI cable supports the data transmission rate of 5Gbps, and can transmit up to 30 meters, which is enough to cope with a video of 1080p and an 8-channel audio signal. However, since the demand for a 1080p video and an 8-channel audio signal is less than 4GB/s, the space of HDMI cable is still very large.

This makes it possible to connect DVD player, receiver and PRR with one cable respectively. In addition, HDMI supports EDID and DDC2B, so the device with HDMI has the characteristics of "plug and play", and the signal source and display device will automatically "negotiate" and automatically select the most suitable video/audio format.

5. According to the different electrical structures and physical shapes, HDMI interfaces can be divided into four types: A, B, C and D. ..
