ExtremeLink PC-on-TV technology offers the transmission of high quality video and USB 2.0 to deliver all types of PC interactions wirelessly over 802.11n including the ability to browse the Internet, access email, instant message, create documents, stream content off of a flash drive, play games, and much more.
HomePNA is the ITU standard (G.9954) that allows for high performance communications across coax and phone lines. To date, over 13 million HomePNA chips have been shipped and nearly 2.5 million homes now run IPTV-based services on HomePNA.
Transitioning television to Internet-style one-to-one addressable advertising can be done gradually in cable television, while implementing the SCTE 130 standard from the Society of Cable Telecommunications Engineers, by utilizing a virtual zoning approach.
Delivering video across a variety of platforms involving multiple codecs can be efficiently handled by multicore media processors. Part One is an overview of the challenge and the codecs involved (including the rarely-mentioned MPEG-3!)
The cable-TV industry needs to move to targeted advertising, but cost challenges such as HD ad splicing and additional infrastructure requirements make it slow going. Here’s a gradual approach that cable-TV MSOs can begin deploying without the need for new set top boxes.
Built In Self Test (BIST) in active HDMI and other high-speed digital cables provides better accuracy and cost savings compared with earlier in-production testing methodologies, and can also improve production line performance.
Understanding how diversity antenna systems work, and how Mobile Digital TV viewing can be improved through the use of multiple antennae — even for space-constrained portable devices, and for in-vehicle and deep-indoor reception.
Picture quality measurements based solely on detecting the noise differences between the reference and test videos fail to account for the characteristics of human perception and have broad limitations as a result.
HDMI can be a highway for ESD to enter the system chip, but an integrated HDMI interface solution can provide the protection needed, while helping reduce manufacturing costs.
HDBaseT is optimized for video applications and can connect all the entertainment devices in a home by providing the “5Play” convergence of uncompressed full HD digital video, audio, 100BaseT Ethernet, power over cable and various control signals.
A low-cost solution using high-speed current feedback (CFB) amplifiers makes CAT5 transmission of 1080i high definition component video easy for cable lengths up to 500 feet.
