It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA. HDMI connects digital audio/video sources such as set-top boxes, Blu-ray Disc players, personal computers, video game consoles, and AV receivers to compatible digital audio devices, computer monitors, and digital televisions.

While this resolution has been superseded in the personal computer market, it is becoming a popular resolution on mobile devices[2]

54 ExpressCard slot -
ExpressCard is a hardware standard replacing PC cards (also known as PCMCIA cards), both developed by the Personal Computer Memory Card International Association (PCMCIA). The host device supports both PCI Express and USB 2.0 connectivity through the ExpressCard slot, and each card uses whichever the designer feels most appropriate to the task. The cards are hot-pluggable. This is an open standard by ITU-T definition which can be obtained from the ExpressCard website. However, a US$2,500 fee[1] is required to access the documentation for non-PCMCIA members.

Four-pin IEEE Firewire 1394 port-
IEEE 1394 connectors are used to connect FireWire® devices such as host controllers, adapters, hard drives, hubs, repeaters, and card readers. FireWire, a registered trademark of Apple Computer, is a communications protocol for the transmission of data, video, and audio over a single cable at very high bit rates. IEEE 1394 is an interface standard adopted by the Institute of Electrical and Electronics Engineers (IEEE) for digital data transfers at 400 Mbps. The popularity of IEEE 1394 is due in part to its use of a bus-powered architecture that does not require peripherals to supply their own power. Products that support the IEEE 1394 standard adhere to its specifications, but often use proprietary trade names. For example, Sony uses the term iLink® to describe its FireWire products. iLink is a registered trademark of the Sony Corporation.
