The liquid crystal display television is reigning supreme in the markets, thanks to the innovative ideas that are incorporated in it. One of the advantages of the LCD is that every television set comes out to the market has at least one HDMI port. The high definition multimedia interface (HDMI) is a new standard of high definition cables, which is a simple system that blends both video and audio into a single high band width. To be precise, the system facilitates uncompressed data transfer of audio and video from other consumer electronic devices to the digital television. This novel high definition multimedia interface will be able to connect the digital television with devices like Blue Ray and High definition DVD players. The earlier version of digital visual interface (DVI) could transfer only audio signals.

Many leading LCD television manufacturers have incorporated their brands of HDMI in the products. The Panasonic has Viera Link, Sony has Bravia Sync and Sharp has Aquos Link. These are a few to point out in this context. The HDMI incorporated systems will be conspicuous by the absence of several cables behind the television set.
