LAS VEGAS At the 2007 Consumer Electronics Show here Monday (Jan. 8), high-definition video IC provider Silicon Image Inc. rolled out a pair of VastLane High Definition Multimedia Interface (HDMI) 1.3 receiver chips, including the SiI9135, which it claimed is the first HDMI receiver to support high-bit-rate (HBR) audio. The company also introduced the first two VastLane transition-minimized differential signaling (TMDS) switches.
According to Silicon Image (Sunnyvale, Calif.), the SiI9135 is designed for use in audio/video (A/V) receivers, while the SiI9125, designed for use in HDTVs, is a, dual-input HDMI receiver that offers manufacturers a drop-in upgrade to add HDMI 1.3 capabilities to HDTVs.
"This integration helps us to increase penetration of HDMI 1.3, not just the high-end, but also in mid-range TVs," said Waheed Rasheed, a product marketing manager of consumer electronics products at Silicon Image. Rasheed added that HDMI is now considered a "check box item" and that the "HD experience" is becoming mainstream.
Silicon Image said manufacturers can pair the SiI9135 with the recently announced SiI9134 transmitter chip in order to create a complete solution. The SiI9134 integrates into HD DVD and Blu-ray Disc DVD players and recorders and supports the transmission of Deep Color content—-which offers billions of colors--and up to 1080p resolution at 60Hz and 12-bit color depth, according to the company. The SiI9135 offers support for the latest HD audio formats, Silicon Image said. The support for HBR audio enables A/V receivers to play back compressed lossless audio formats, including Dolby True HD and DTS-HD.
According to Silicon Image, the SiI9125 receiver enables HDTVs to display Deep Color content transmitted by a new generation of consumer products, such as the Sony PlayStation 3 and high-definition DVD players. The device offers a cost effective means of implementing dual HDMI inputs for simultaneous connection of multiple HDMI source devices, such as a DVD player and a set-top box to a DTV, Silicon Image said. The SiI9125 also offers a built-in high-bandwidth digital content protection (HDCP) decryption engine and supports both Super Audio-CD and DVD Audio, including 7.1-surround audio at 192 kilohertz and stereo audio at 192 kilohertz, Silicon Image said.
Both the SiI9135 and SiI9125 support 10-bit and 12-bit color depths (4:4:4 RGB or YCbCr), up from the 8-bit color depths displayed in the current generation of HDTVs, Silicon Image said.
The SiI9135 receiver is available immediately and is priced at $12 per unit in 10,000 unit quantities, Silicon Image said. The SiI9125 is priced at $8 per unit in 10,000 unit quantities, the company said.
