ASUS introduced a new line of Wireless for HDMI products for the digital home, including accessory devices and embedded designs that dramatically simplify connections between home audio and video electronic components. Based on innovations in ultra wideband technology by Tzero and JPEG2000 from Analog Devices, these new products enable distribution of high-definition video streams around the home. This significantly reduces installation and equipment costs for service providers.
The ASUS-designed and built Wireless for HDMI products feature non-line-of-sight operation that enables devices to communicate wirelessly through walls and extend across multiple rooms. It also features transmission quality equal to that of wired solutions. The input from video devices can be HDMI, component video, and analog audio. The output to the HDTV is industry-standard HDMI. Full HDCP (High-bandwidth Digital Content Protection) compliance is supported, allowing protected content to be displayed to an authenticated display.
With Tzero, the new product will operate wirelessly to connect devices throughout the home. It will deliver transmission speeds of up to 480 megabits per second (Mbps) to support even the highest demands of high-definition video and IPTV. Tzero's platform is based on standards from the WiMedia Alliance and is guaranteed to coexist with other WiMedia-compliant devices.
Transmission of high-definition quality video in the Wireless for HDMI solution is enabled by Analog Devices' JPEG2000 video compression ICs, which are compliant to the royalty-free JPEG2000 standard. On the transmit side, video data is compressed using Analog Devices' ADV202 JPEG2000 video codec, combined with audio, then packetized and encrypted, and transmitted via the Tzero MAC and PHY chip. The RF chip transmits over the air to the receiver where the audio/video data with HDMI is decompressed and presented to the display device via the HDMI port. Analog Devices' HDMI interface ICs and audio processors complete the design, ensuring the highest quality audio/visual experience.
