An HDMI cable is high definition multimedia interface, this cable can carry signal for audio and vi
deo inside one cable which makes for simpler connections. To use analog connectors would take nine individual cables to equate what the HDMI can handle. HDMI is capable of 1080p video, that's sixty frames a second, which is currently the highest video standard; and on audio it handles eight channel of 24 bit 192Khz which is enough for Dolby TrueHD and DTS-HD, the two highest standards in audio. HDMI can also enable devices to communicate which helps setups. Such as when you connect a game system to the TV, the game system is able to tell the television the mode of video it's using so the TV can set itself automatically for the right resolution. HDMI is also backward compatible with DVI, there are easy cables and adapters for connecting DVI and HDMI electronics together. A Mini-HDMI is similar to a mini USB in that the pin shape is the same as the regular HDMI just smaller in size. This is popular for the portable electronics such as digital camcorders where the smaller space works more efficiently. It can be connected to a normal size HDMI port by using an adaptor. HDMI also has a couple of different versions, 1.3 has extra bandwidth enabling it to support a more complex audio and video, but version 1.2 will support all the audio and video standards on the market now. There is an a and b versions of 1.2 and 1.3, and they use a different way to test the data, but doesn't impact the compatibility or quality. There are differences in the logo of "standard" and "high speed" cables, standard is certified for use up to 75Mhz (version 1.2), where a high speed cable was tested to 340Mhz (1.3). A standard cable may be able to manage the 340Mhz it's just not certified for that speed. The prices between the two are similar so go ahead and get the high speed cable. The differences about regular HDMI cable and high grade HDMI cables is just the price, about $30 to $40. This is a digital cable so there's no degrading of the signal such as you can get with a analog cable, the signal is either there or it's not. HDMI standard length composed of plain copper wire is 33 feet, but a longer cable can do the job also without a signal repeater being used. Closed captioning does still work when you implement HDMI, the digital televisions have the closed captioning supported by the receiver not the television. For the captioning to function it has to be turned on from the source component such as the cable box. Then the HDMI moves the video data with the captioning as already part of the image, not separate video and captioning data like it was done previously.
