Buy HD Digital Video Tapes for Your Next Production Work


HD DV tapes (High Definition Digital Video Tapes) are designed for recording and playing back of digital signals instead of analog video signals. Launched in 1995, this tape format has become an ideal choice for videographers of today.

The video coding in DV tapes compress the recorded video on a frame-by-frame basis, while storing the audio uncompressed. The Digital Interface Format (DIF) is the basic unit of recorded data on tapes. The audio, video and metadata are packaged into 80-byte Digital Interface Format (DIF) blocks which are combined into a 150-block sequence. The DIF blocks could be stored as file formats like AVI (Audio Video Interleave), Quick Time and MXF (Material eXchange Format). A video frame in a DV tape is formed by 10 or 12 sequences, based on scanning rate of video and audio contents. Once the video and audio signals get written to the tape, each sequence is defined as a complete track.

However, with the advancement of technology, Sony and Panasonic have introduced some latest versions of digital video tapes. Almost all the DV tapes use same compression system but differ in features like color rendition, robustness, editing functions and scanning pattern.
