Alternative Karaoke playback devices

The CD+G format of a karaoke disc, which contains the lyrics on a specially encoded subcode track, has heretofore required special—and expensive—equipment to play. Commercial players have come down in price, though, and some unexpected devices (including the Sega Saturn video game console and XBMC Media Center on the first Xbox) can decode the graphics; in fact, karaoke machines, including video and sometimes recording capability, are often popular electronics items for sale in toy stores and electronics stores.

Additionally, there is software for Windows, Pocket PC, Linux, and Macintosh PCs that can decode and display karaoke song tracks, though usually these must be ripped from the CD first, and possibly compressed.

In addition to CD+G and software-based karaoke, microphone-based karaoke players enjoy popularity mainly in North America and some Asian countries such as the Philippines. Microphone-based karaoke players only need to be connected to a TV—and in some cases to a power outlet; in other cases they run on batteries. These devices often support advanced features, such as pitch correction and special sound effects. Some companies offer karaoke content for paid download to extend the song library in microphone-based karaoke systems.

CD+G, DVD, VCD and microphone-based players are most popular for home use. Due to song selection and quality of recordings, CD+G is the most popular format for English and Spanish. It is also important to note that CD+G has limited graphical capabilities, whereas VCD and DVD usually have a moving picture or video background. VCD and DVD are the most common format for Asian singers due to music availability and largely due to the moving picture/video background.
