According to announcements by manufacturers, new high-definition DVD formats (HD-DVD and Blue-ray) and game machines (including the Sony PLAYSTATION? 3) ; Digital televisions which include LCD TVs, plasma displays and rear projection microdisplays will be able to present images that are closer to real life than previously are all make use of capabilities added in HDMI 1.3.

12. Are new HDMI versions compatible with previous versions?

Yes, all versions of HDMI are backwards compatible with all of the previous versions of HDMI. Backwards compatible means that the newest version will also work with any previous versions, ensuring that older electronic components will also be able to be connected.

13. What are the mainly performance should the insulating materials of power cable have?

They should have performance as below: (1) high disruption ability, (2) low dielectric loss ,(3)high insulation resistance, (4) nice performance of discharge, (5) fairly flexibility and mechanical strength, (6) the performance of insulation must be long term stability.

14. Where are the parts of the inside shield and outer shield of the power cable? What materials are they? Whar functions are they?

For the better touch of insulation layer and connector, The elimination of the conductor surface is not smooth due to the conductor surface electric field strength increases, Usually in the conductor coated with a metalized paper or the inside of the semiconductor tape shield. In order to make insulation and metal jacket good contact, and general appearance of bread in the insulating layer have the outer layer of shielding. The same screen on the outside layer and the internal display layer of material, sometimes outside bar copper tape or braided copper wire with.

15.What is a Crossover cable?

A crossover cable is a network cable that is terminated differently on one end (green and orange pairs switched). This cable is used to connect two computers together without a switch. It is also used to directly access some network hardware.
