Silicon Image pioneered the HDMI specification to enable the transmission of premium digital content over an uncompressed, secure digital video and audio interface for consumer electronics. HDMI has been endorsed by studios and broadcasters for the delivery of premium high-definition programming. Silicon Image's HDMI technology includes High-Bandwidth Digital Content Protection (HDCP), supported by Hollywood as the technology of choice for the secure distribution of premium content. Silicon Image was the first company to ship HDMI-based chips and the first to provide HDMI functionality for consumer products. In addition, Silicon Image is the primary author of the HDMI Compliance Test Specification, and hosts numerous HDMI Authorized Testing Centers in the world - supporting ultimate compatibility among HDMI products and those licensing the PanelLink Cinema core.

Silicon Image offers HDMI Transmitter and Receiver IP cores which include the digital logic and analog PHY. In addition, Silicon Image is the only company offering low-cost HDMI digital only IP cores for use with an external PHY semiconductor provided by Silicon Image (SiI9002, SiI9204, SiI9206 HDMI transmitter PHYs and SiI9003 HDMI Receiver PHY). These configurations offer both a lower bill-of-material cost and faster time-to-market at reduced technical risk than using full discrete HDMI Tx or Rx chips.

The HDMI transmitters are ideal for DVD and Blu-ray Disc players and recorders, set-top-boxes, personal video recorders and A/V receivers. The HDMI receivers are ideal for Digital TVs and Deep Color displays, video projectors and A/V receivers.

Silicon Image’s new HDMI 1.4 transmitter and receiver support also HDMI 1.3 and in addition enable connectivity of all these devices to a multimedia home network.
