- Description
- The WTV (Windows Recorded TV Show) file format is used by Microsoft's Windows Media Center to store TV recordings. Introduced with Windows 7 as a successor to the earlier DVR-MS format used by Windows XP Media Center Edition, WTV files allow users to record live television broadcasts or schedule recordings directly through their computers equipped with a compatible TV tuner card. These files encapsulate both the video and audio streams, along with metadata such as broadcast information and closed captions.
- A lossy file format used to compress speech in Global Standard for Mobile (GSM) telecommunications. It is very effective for reducing audio file size. However, encoding and decoding audio signals severally is discouraged as the final product will have a lot of noise. Popular with some voice mail software but it is CPU intensive.
