Comprehensive exhibition " CEATEC JAPAN of image, information and communication 2003 " on the 7th, commenced with the Chiba prefecture * Makuhari ???. Blue ray disk-related session was held on the 8th is 2nd day, representation of affiliated each company did lecture.
The Matsumura pure filial piety person of the pioneer corporation execution official research and development headquarters assistant director and AV development center chief, introduces the present condition of the blue ray disk (BD). From this year extending through next year and aims toward 2 time speed with type you said it rewrites the road map was presented.
Consequently the Noboru platform it did, the Ogawa elegance clear person of Mitsubishi Electric Corporation advanced technical research institute accumulation media engineering department Department Manager explains summary of the BD, concerning densification technology and signal processing system et cetera.
Besides the fact that with the BD thickness of protective layer with the 0.1mm, substantially thin thing, became strong in the curvature and inclination of the disk by comparison with the 0.6mm of the DVD, inexpensively high density / the point which can actualize large increasing capacity it explained.
In addition, there to be a feature that, it can be done high-speed record with low laser power, presently 2 time speed in the midst of development. If it is actualized, you chase and playback and simultaneous video recording playback et cetera become possible. In addition, you say as much as 4 time stenography record is actualized at academic society level.
Also development of finishing of the disk is advanced, you say the cartridge is not with also the technology which is made available is researched.
The road map of BD-RE/BD-R/BD-ROM
In addition, also standardization circumstance of the BD physical format was introduced. Already, the Ver.1.0 is released in July of 2002, as for " BD-RE " of the rewriting type where also the corresponding equipment is sold, the Ver.1.01 of correction edition is open in July, presently 2004 years halfway in the midst of job of the Ver.1.1 of issue schedule calls.
With the Ver.1.1, besides the fact that 2 layer record of the largest 54GB is included, 2 time stenography record (72mbps) is supported. In addition, the cartridge which presently becomes necessary option handling the possibility that dearly, the " bear disk " is adopted.
Concerning " BD-R " of postscript type, 2004 years we make the Ver.1.0 release schedule halfway, this way with 2 layer /2 time stenography record, the cartridge is not becomes the bear disk. Furthermore, the possibility that also playback private standard " BD-ROM " for the package media is decided in beginning of 2004, becomes bear disk specification of 2 layer.
Osamu Hiroshi Ogawa of the SONY broadband network company optical Headquarters-research & Development, utilized the special photoresist " phase transition mastering (PTM)" and, explained the compilation process of optical protective layer concerning the key part / the technology which actualizes densification record.
In addition, you say we are advancing also research, concerning the protection of the cartridge less disk we solve with surface coat concerning the soiling of the fingerprint and the like. If at the meeting place, attaching the fingerprint to the disk which administers hard coat, it releases the animated picture of the demonstration which does playback and usually it is use, it emphasized that it has sufficient protective efficiency even with the bear disk. Consequently, the actual development case was listed concerning the Blu-ray2 layer disk pickup and the BD and the CD/DVD interchangeable pickup.
Small mound elegance of the American Matsushita Electric Co. Panasonic Hollywood laboratory ? the chief and the Don * ????? person of the Colombian Tristar foam/home entertainment advanced * technology * vise President talked concerning BD-ROM standard and the conception et cetera of the package media.
The ????? person the DVD making the big market is high appraisal. The on that, with the BD-ROM subtitle of the language which is not recorded in the disk, is downloaded by way of Internet, you say new development is expected, e.g., the user makes subtitle size modification possible.
Actually, the game and the new forcing menu picture et cetera where actualization is expected with the BD-ROM were presented making use of the image data " of ????????? 2 ".
Consequently, the small mound person did the explanation of the standard of the BD-ROM. At the time of the development of the BD, we assume, " grope the new business model Hollywood the Hollywood opinion was adopted to the maximum. For example not to be business of the completion type like clearing the rental and the DVD of the VHS, e.g., also the rear of the selling can offer the contents by way of the network, " the request that something we would like to do new thing ", is strong ", you say.
Specification request from movie company
The constitution plan of BD-ROM
It gathers the opinion such as that, with the BD-ROM, does also the development of network extended function. At that time, it seems that great load does not fall on authoring and the like, you say it keeps considering even in service of contents production environment.
In addition, in regard to the image format, obtaining the Hollywood cooperation, staff and others of the studio and it did the relative and examination job of picture quality. As for comparison those which view the MPEG-4 AVC which with the MPEG-2 and the AOD (HD DVD) which have been adopted with the BD has been adopted with identical environment.
According to the small mound person, concerning the reproducibility of material feeling " the MPEG-4 AVC and as for the MPEG-2 you call equality ". But, if at bit rate to the 12mbps - the 25mbps, " it is which bit rate, in the point it can withstand HD package use?", at the point where the studio authorized personnel tests with subjective appraisal, the around 20 - the 24mbps of the MPEG-2, answer that " of the OK " could be obtained from the most authorized personnel. On one hand with the MPEG-4 AVC, you say you could not obtain agreement to higher bit rate.
Such opinion and considering the encoder / decoder Lsi the development circumstance and the affinity et cetera of digital broadcast, as a record format for the HD movie, " with the HD movie the MPEG-2 being preponderantly profitable, there is no merit which adopts the MPEG-4 AVC ", you declared.
In addition, in regard to copyright protection, being joint with Hollywood, we are advancing development, introduce also pirate edition measure technology. By the fact that information for contents playback is housed physically in the disk itself, it has made measure to the large-scale pirate edition trader and the like.
BD-ROM standard, presently at stage of the Ver.0.9, calls the basic specifications you have completed. It comes and you say presently, examination of extended function such as network function is done destined for the Ver.1.0 of the summer.
In addition, also ascent one record mechatronics Department Manager NHK broadcast engineering and research Nakamura does, the Noboru platform introduces the NHK match and the like which is directed to digital broadcast. It referred, the merit of the optical disk camera and the like on broadcast site, cheered to the BD.
Lastly, the flax warehouse ? loyal retainer person of the digital media critic, does proposition, as a blue ray user the case where it compares with the D-VHS the head puts out and explains the easy sheath and the merit et cetera. In addition, since starting the video recording of BS high vision " terrestrial analog something the air which is seen stopped doing ", and so on charm of high vision the thermal valve was done.
" Unless you look at digital high vision, the value which has lived it is not ", and so on mixing humor, you explained, you expressed the ROM media and the expectation et cetera to the hybrid model as an opinion from the user.
