IP core architecture supporting both HDMI and MHL connectivity standards in a single-chip solution
The Dual-mode HDMI Receiver and MHL Receiver IP Core supports the latest HDMI 1.4a feature set, including 3D, 4K, HDMI Ethernet Channel and Audio Return Channel, as well as MHL functionality. This dual-mode core includes digital logic, analog GDSII, models, software, and documentation.
The Dual-mode HDMI Receiver and MHL Receiver IP core was developed to support two HD video connectivity standards - MHL and HDMI. In HDMI mode, Silicon Image's Dual-mode Receiver IP core supports HDMI 1.4a features, including all mandatory and optional 3D video formats and all 4Kx2K formats. The dual-mode IP core also supports HDMI Ethernet Channel to send and receive data via 100 Mbps Ethernet over an HDMI cable, while Audio Return Channel allows a TV to send audio streams from the TV to an HDMI attached A/V receiver for improve sound. The built-in Consumer Electronics Control (CEC) connection allows the user to operate multiple devices with one remote control.
In MHL mode, the dual-mode IP core supports video resolutions up to 1080p, allowing mobile devices such as smartphones, HD camcorders and portable media players to display HD content by connecting to HDTVs using existing connections. The built-in Remote Control Protocol (RCP) connection enables the user to operate multiple devices with one remote control.
The dual-mode IP core supports all relevant audio formats up to 8-channel digital audio, while its color space converter allows convenient interfacing with most video interfaces. The core is configurable, providing SoC designers access to multiple internal interfaces and hardware blocks, potentially reducing integration time and gate count. The core includes digital logic, analog GDSII, models, software and documentation. The first implementations of GDSII will be in 55 nm and 65 nm processes. In addition, this IP core supports High-bandwidth Digital Content Protection (HDCP) for both HDMI and MHL modes.
