EDID is read by a video source (player) from the video sink over DDC lines using an I 2C protocol.
Since these are not essential to the application described here, they are not discussed in this article.ĮDID data comprises a 128-byte long (VESA-Video Equipment Standards Association) or 256-byte long (CEA-861-Consumer Electronics Association) data block that describes the video and (optionally) audio capabilities of the video receiver (Rx). In addition to these multimedia signals, the interface includes display data channel (DDC) signals for exchanging extended display identification data (EDID) and for high-bandwidth digital content protection (HDCP).Īdditionally, HDMI interfaces can be equipped with consumer electronics control (CEC), audio return channel (ARC), and home Ethernet channel (HEC). HDMI interfaces use transition-minimized differential signaling (TMDS) lines to carry video, audio, and data in the form of packets. Introduction to HDMI Application and Video Standards

This article also shows how to interconnect these video technologies. While HDMI has become a defacto interface for HD video, VGA is still the most common interface on a laptop. Two basic devices-HDMI-to-VGA (“HDMI2VGA”) and VGA-to-HDMI (“VGA2HDMI”) converters-provide engineers familiar with video applications with an easy way to transition between analog video and digital video.

This article shows how advanced silicon solutions and smartly implemented software can facilitate HDMI implementation. However, advanced silicon solutions are increasingly available to tackle the problem of implementation complexity, achieving improvement in both analog and digital domains they include higher performance blocks to equalize poor differential signals and more complex algorithms to reduce software overhead and correct bit errors. This might seem a bit overwhelming-as is often the case with new technology. New adopters may see HDMI as a relatively complicated standard to implement, requiring a validated software driver, interoperability checks, and compliance testing to guarantee proper behavior of one device with various other devices.

For example, some customers still prefer to use video graphics array (VGA) cables for projectors, while others use an audio/video receiver (AVR) or media box as a hub, connecting a single HDMI cable to the TV instead of a batch of unaesthetic cables, as outlined in Figure 1. These devices still use analog signaling as their only means of transmitting video, possibly due to specific requirements of a particular market or application. In some industrial applications, however, the transition from analog video to digital video is taking longer than in the consumer market, and many devices have not yet moved to the new digital approach of sending integrated video, audio, and data. In addition to improved market acceptance, using a standard interface greatly improves compatibility between projectors, DVD players, HDTVs, and other equipment produced by various manufacturers. Implementation of a standardized multimedia interface was driven by a highly competitive consumer market where time to market is a critical factor.

Already popular in home entertainment, HDMI interfaces are becoming increasingly prevalent in portable devices and automotive infotainment systems. The consumer market has adopted High-Definition Multimedia Interface (HDMI ®) technology in TVs, projectors, and other multimedia devices, making HDMI a globally recognized interface that will soon be required in all multimedia devices.
