  • Hitachi's Broadcast/Network Hybrid Digital Recorder
    Hitachi’s Broadcast/Network Hybrid Digital Recorder 66 Hitachi’s Broadcast/Network Hybrid Digital Recorder — A Whole New Way of Watching Media — Atsushi Ugajin OVERVIEW: In the market for video recorder units, DVD (digital versatile Tsutomu Numata disk) recorders have seen explosive growth in recent years. HDD (hard disk drive)/DVD recorders in particular are predicted to enter households quickly, because of their convenience. The rapid increase of households connected to broadband networks has also caused an increase in the number of PCs and "information appliances" that can connect to networks and communicate from within the home. This has led this phenomenon to be referred to as a fusion of broadcast and communication within the home. With this concept in mind, Hitachi developed a new type of HDD/DVD recorder. In future, Hitachi will develop a hybrid digital recorder as the core of the home network, while expanding the capacity and features of the hard disk, the recorder’s key component, and making it more quiet and energy efficient. INTRODUCTION (b) boosted hard drive performance and capacity, DVD (digital versatile disk) recorders recently joined (c) advances in moving image digital recording the ranks of flat panel plasma TVs and digital cameras technology; as must-have digital gadgets, and all three items (d) integration of technology as a result of the shift continue to be shipped in Japan in increasing volume. from analog to digital, This is especially true of DVD recorders, 830,000 of (e) increased network speed. which were shipped in Japan between January and (2) User needs August 2003, as they begin to enjoy real demand.
