Scott, Glenview monitors this site. Like to broaden the readership/participation to include thousands of other investors/brokers/fund managers wanting to capitalize on the CE digital revolution. Any ideas?

For several months, Korea has weighed the American standard, known as ATSC (Advanced Television System Committee), against the European standard, called DVB-T (Digital Video Broadcasting-Terrestrial). The American standard received broad support from members of the Committee for Promotion of Terrestrial Digital TV Broadcasting. The committee, consisting of experts from the electronics industry, broadcasting community and academia, recently recommended that the Ministry of Information and Communication (MIC) adopt ATSC. Accommodating this suggestion, the ministry said yesterday that the American standard proved to be more suitable for Korea in technological, economic and service terms. On the technological side, the two standards differ in channel frequency bandwidth, audio signal compression and transmission, while for video signal compression and multiplexing, they both rely on the same MPEG-2 specifications set by the Moving Picture Experts Group (MPEG). In channel bandwidth, ATSC allocates 6 megahertz (MHz) to each channel, while DVB-T uses 7-8 MHz. In Korea, as in the United States, the current analog TV broadcasting system allocates 6 MHz to each channel. This means ATSC will make it easier for Korea to move from analog to digital in TV broadcasting. For audio compression, the American standard uses Dolby AC-3, while the European format follows MPEG-2 audio specifications. Dolby AC-3 is a higher-level audio standard than MPEG-2. The European firms which hammered out DVB-T stopped short of adopting Dolby AC-3 in consideration of the multiplicity of languages used in European countries. In transmission technology, the American standard uses a method called vestigial side band (VSB), which was developed by Zenith Corp., an American electronics company now owned by LG Business Group. The European transmission mode is called orthogonal frequency division multiplexing (OFDM). According to MIC, VSB is a proven technology as it is a modification of an existing analog modulation method. Compared with OFDM, it is easier to implement and offers a higher data rate. OFDM excels VSB in channel efficiency as it enables a broadcasting station to cover the whole nation with a single frequency network (SFN). With VSB, a broadcasting company would have to use several frequency bands for nationwide coverage. OFDM is also better than VSB in terms of its capability to send signals to mobile TV sets and ghost prevention. In economic terms, ATSC offers a bigger business opportunity for Korean manufacturers of TV sets and broadcasting equipment than DVB-T, as the United States is the world's largest market. Both in the United States and Europe, digital over-the-air TV broadcasting will begin in 1998. But in Europe, the market for digital TV sets is expected to grow more slowly than in the United States, where digital TV is already popular thanks to the satellite-based services introduced by Hughes Corp. in 1994. By 2006, American demand for digital TVs is expected to reach 130 million sets, while the European demand will total 23 million sets, according to an industry forecast. In addition, Korean TV manufacturers have already accumulated considerable expertise in ATSC-based TV sets because the government-initiated digital TV development program has been focused on ATSC since it was first suggested in 1990. For instance, LG Electronics recently developed a set of chips enabling production of low-cost, small-sized digital TV sets based on ATSC. MIC also said that ATSC requires less investment by broadcasting companies than DVB-T. The estimated cost saving is 1.2 trillion won. In terms of service, the American standard is a better choice for broadcasting companies as it allows them to air programs in two formats, either in standard-definition TV (SDTV) or in high-definition TV, depending on the nature of the program. For instance, they can provide programs that require higher resolution like an opera performance or sports event in the HDTV format, while offering ordinary programs like dramas in the SDTV format. The European standard is basically designed to offer programs in the SDTV format. But work is underway by European firms to incorporate the HDTV format in their standard. Considering all these factors, Korea's choice of ATSC appears to be appropriate. But domestic TV manufacturers will continue their R&D on DVB-T because Europe is a large market they cannot afford to ignore. The government's decision on the Korean digital TV standard came some eight months after it began deliberation on the two standards in March this year. MIC said it will specify details of the standard by the end of next year, one year ahead of the scheduled launch of trial digital TV service in 2000. But Korean TV manufacturers are moving to develop digital TV sets before 1998 to carve out a share in the American market. For them, the American market is of vital importance as it will determine their success or failure. \| Previous \| Next \| Respond \| View SubjectMarksBookmark this Subject Return to Semiconductors One or more words separated by spaces: Subject Titles Only Full-Text Messages with Links <Picture> Send questions and feedback to webmistress@techstocks.com To link to this reply, use the following Location: Terms of Use
