Chang, Shen-Chen. "The role of institutional entrepreneurship in standard wars : the case of Blu-ray Disc." Thesis, Birkbeck (University of London), 2013. http://bbktheses.da.ulcc.ac.uk/65/.
Full textAbstract:
The study is to use institutional entrepreneurship perspective to complement the functionalist’s viewpoint to understand the process underlying collective action in a mature eco-system and how institutional entrepreneurs manage critical stakeholder relations, collective action and discursive activities in technical standard change processes. The standard war of Sony Blu-ray Disc vs. Toshiba HD DVD is used as a critical and intrinsic case. The functionalist’s viewpoints have paid much attentions to the numbers of customers adopting new technologies, and etc. By means of institutional entrepreneurship perspective, it claims that it does not matter about the number and amount, but it does matter about how focal firms make the markets believe that they have the abilities to win standard wars. The study further claims that the variables studied in functionalist’s viewpoint also have the meanings of institutional entrepreneurship perspective. Moreover, the BD and HD DVD standards are incremental innovations in a mature field where there are many things are settled down. Focal firms can easily forecast the expectations of the dominant institutional logics. The study contributes that institutional entrepreneurship perspective still provides the process insight to complement the functionalist’s viewpoint. This perspective can be applied in emerging field, where it is no dominant logics and the innovations are likely to be radical. The BD case represents a critical case. It can makes possible naturalistic generalization to other similar contexts. Eisenhardt’s principles are used to build theory from the case study. I borrowed techniques of open coding to analyze the data. The findings show that collective action (including critical stakeholder management and structuring collaboration capabilities) and discursive activities are the central features of institutional entrepreneurship. They have mutual relationship with the institutional entrepreneur’s resources (power and legitimacy). Furthermore, good collective action and discursive activities can lead to network effects and product performance.

L’objectif ultime de ce travail était de mettre en place une méthodologie générale permettant de comprendre l’origine de la perte d’information de disques optiques numériques exposés à des contraintesOptical discs are often used by many private or public organizations to archive essential data. For a long time these media were supposed to be reliable. However, a loss of the stored data was highlighted, sometimes only after a few years of storage. This degradation was attributed to the discs ageing, without any identification of the materials involved in this ageing. This work aimed to determine the chemical and physical modifications resulting from the application of different stresses (photochemical, thermal and hydrolytic) on the materials used in optical discs : the CD-R polycarbonate substrates, the recording layers based on phthalocyanines and azo compounds, and the protective layers. The study of this last component allowed us to extend the researches to the case of the Blu-ray Disc. These physico-chemical modifications were then correlated to variations in digital and analog parameters of discs submitted to the same stresses. The ultimate objective of this work was to propose a general method that could help to understand the origin of the loss of information of optical discs submitted to stresses

This study is focused on the competitive strategy analysis for Blu-ray DiscDrive (BD). The development history of video storage is from analog products like cassettetapes, VHS to digital products like CD, DVD. A new generation product replacement is triggered off while new technique is mature and selling pricedeclines to the market mainstream price. UP to now, suppose the BD should substitute DVD, however there is no positive response from the market. More products to substitute storage device comes out such as hardware products, i.e., high capacity hard disc and flash memory, as well as communication internet with cloud application. The video content can be easily downloaded through mobile products, e.g., smart phone, Tablet PC, Ultrabook and fake mobile products. Mobile product becomes the market trend. All mobile products don’t dispose DVD and BD. The competitive strategy analysis is based on four theory models: PLC analysis, five force analysis, SWOT analysis and BCG Matrix analysis to predict BD industry in the future.A real industry expert review withcase analysis is also presented to verify the results.It can be concluded that BD industry is very weak and will be withdrawn from the market within 10 years due to the change ofuser’s habit by cloud application.

The low efficiency of traditional pickup head is limited by the difference of vertical divergent angle and horizontal divergent angle. The vertical divergent angle is much larger than the horizontal one. To get the circular laser beam, the collimating lens is designed with the divergent angle which intensity is in the horizontal direction. Therefore there is a lot of energy wasted. This thesis uses the cylindrical afocal system and the prismatic system to expand the beam separately in the horizontal direction. The expander makes the beam size which intensity is in the horizontal direction as large as the beam size which intensity is in the vertical direction. Then the highly efficient collimating lens is designed with the divergent angle in the vertical direction. First, this thesis designs traditional Blu-ray Disc pickup head. It covers the design of its objective lens, the design of its collimating lens, tolerance analysis and the focusing error signal, and then simulates the total efficiency. This thesis introduces the concept of beam expanded in the horizontal direction to improve the total efficiency. This thesis designs the cylindrical expander and prismatic expander. It also covers the design of the collimating lens, tolerance analysis and the focusing error signal, and then simulates the total efficiency. At last summarize all of the new designs which are proposed by the thesis.

This work investigates recording bits on recordable and rewriteable blu-ray discs using atomic force microscopy (AFM) and conducting atomic force microscopy (CAFM) with high contrast, respectively. The geometric structure of the recording bits is clearly observed in image, which, when coupled with cross-section analysis, yields precise bits dimensions, and edge horizontal extended length (EHEL) values. The microscopic results are a valuable reference for increasing the recognition rate of digital signals in optical storage media. Furthermore, such a rapid and convenient measuring mode is an indispensable research tool for developing new recording materials and improving formation mechanisms.

One of the most effective solutions to patent thickets is the patent pool which multiple licensors unify to license their complementary patents in a package. However, academic researches and empirical investigations are not consistent in whether patent pools encourage innovation performance. Since 2008 to 2013, the annual growth rate of Blu-ray discs was from 83% to 120%. In 2013, shipment quantity reached to four hundred and twelve millions. Thus many company have attracted to invest in this industry. This study uses two competing Blu-ray Disc™ (BD) patent alliances as an empirical case to test 3 hypotheses. The study investigated the two competitive BD patent pools, Premier BD and One-Blue BD, to test several hypotheses: whether patent quality of the two patent pools are different, the correlation relationship between patent quality of patent pools and licensees’ financial performance, whether the formation of a patent pool and the characteristic of the pool member influence innovation performance. The study made several conclusions that patent quality of the two competitive patent pools were significantly different, the correlation between patent quality of patent pools and licensees’ financial performance was less significant, the formation of a patent pool and the characteristic of the pool member statically influence innovation performance.

The Blu-Ray Pick-Up Head has been using single aspheric plastic lens instead of multi-piece glass assembly lens so as to reduce the weight of the objective lens and the manufacturing cost in recent development. However, the steepness of lens is increased as the NA value is increased, so that the central thickness and the edge thickness of the lens have large difference. Therefore, during the injection molding process, the objective lens suffers the shrinkage problem which affects the optical quality of the lens eventually. In order to solve above problem, the injection molding experiment is applied for making the objective lens for Blu-Ray Pick-Up Head in this research and the Taguchi method and the mold compensation technique are implemented to reduce the deviation of the shape precision of lens so as to provide an optimization process for manufacturing objective lenses. In this research, a plano-convex lens, 5 mm in diameter and 3 mm in total thickness, was designed by the ZEMAX optical analysis software. The specifications of the lens developed in this study are: the NA is 0.85, the spot size is 0.58 μm and the RMS_OPD is smaller and/or equal to 0.033 λ, these specifications meet the requirements of an objective lens of the optical pick-up head for reading Blu-Ray Disc. During the optimization of the design process, some facts were found: when the NA was high, the steepness of the lens surface was large; while when the total thickness was too thin, the edge of the lens was thinning, so that the lens could not capture the edge light beams to the main optical axis. The key point for correcting the optical aberration of a lens was applying aspheric lens at its two faces and optimizing the coefficient of the aspheric character; introducing a high order coefficient raised the collecting ability of the edge light beams for the lens so as to reduce the optical aberration; however, the edge thickness of the lens should be high enough to set the gate of the mold cavity. Before the injection molding experiment, the Moldex3D software was applied to predict the relationship between the melt filling and the molding parameters. In the experiment, the optical simulation result showed that the aspheric character is the main factor for affecting the optical efficiency of a lens. Therefore, this research applied the Taguchi method for investigating how much the injection speed, the melt temperature, the mold temperature and the packing pressure play on the shape precision of the aspheric character. The deviation of the shape precision is defined by the P-V value which is targeted as lower than 1 μm based on the fault tolerant analysis of a random shaped surface. The experiment revealed that the packing pressure affected the shape precision of the aspheric character mostly, and contributions to the two faces were 37.9 % and 49.8 % respectively; P-V values of the test sample set with the best parameters were 3.84 μm and 6.85 μm respectively; finally, the mold compensation technique was introduced into the test sample set with the best parameters for the injection molding experiment, and the real P-V values of the shape precision were measured as 3.32 μm and 6.17 μm, which showed the reliability of the experiment.

Multimedia technology is the essential part of home entertainment and it makes a great progress from last decade. Content distribution systems are essentially content protection systems that protect premium multimedia content from being illegally distributed. So, it becomes a challenge for digital industries to give protection to their content and the physical distribution system. Devising effective Content Protection mechanisms and building satisfactory Digital Rights Management (DRM) systems have been top priorities for the Publishing and Entertainment Industries in recent years. Advanced Access Content System (AACS) is intended to restrict access to and copy protection of HD-DVD and Blu-ray, which is playing a crucial role in copyright protection during this challenging era for much-renowned companies. In this thesis, we propose a step-by-step design that adopts the AACS copy protection architecture for recordable media, without getting key authorization from AACS LA, which will provide a robust, high compatible and cost-effective content protection system for non-AACS LA enterprise. We emphasize on how to play the BD-R with AACS protection on an unauthenticated AACS player. The result of our design is to protect the BD-R with AACS, which can be easily used by the small and medium non-AACS LA enterprises.

The Micro-Electro-Mechanical System (MEMS) used for the next generation industry has been developed due to the miniaturization of components and systems demands on advanced technology. Micro-injection molding is the most prominent process for successfully forming microstructures with low cost and high precision. However, raising molding temperature is necessitated when getting better fluidity in the fill-in stage using micro-injection molding in order to achieving the exactness of shape. Because of this high-temperature requirement, the pulsed cooling mold temperature control technology has been provided. Using a hot mold during the filling stage and a cold mold during the cooling stage can thereby improve the quality of molded microstructures and without increasing cycle time. In this study, pulsed cooling mold temperature control technology is used to reduce the shaping cycle time and maintain the quality of the products. The Near-Electromagnetic Value is used for controlling the inductor when injection mold opened and closed could lead the sample of blue ray disc shaped well at high temperature holding pressing stage and at low temperature cooling molding stage. Consequently, it was proved that by using the pulsed cooling mold temperature machine to produce blue ray disc is more choicely than by using the traditional mold machine since the results from the experiments showed that the production cycle time could be decreased from 11 seconds to 10 seconds and the disc radial deviation was reduced from 0.45° to 0.15° evaluated by Argus blue tester.

The high definition video and relevant products have become a trend for the movies, television programs and home entertainment market. Therefore, “Full HD” would be the standard of the high definition video in the future. In 2008, the development of HD DVD devices and relevant products was terminated. Blu-ray Disc now is regarding as the main specification for the next-generation DVD market.The innovation diffusion model is divided into three parts: video game console market sub-model, Blu-ray Disc player market sub-model and company revenue and software development sub-system. In the video game console market sub-model, we focus on the PlayStation3 adoption process as the main focus because it can read the Blu-ray Disc directly. Besides, we also consider XBOX360 and Wii as other two players in this market. With regard to the Blu-ray Disc player market sub-model, in the beginning stage of diffusion process, we assumed that there is only one company has the core technology to produce Blu-ray Disc player. Besides, we simulate the company revenue and the software development influences for the adoption rates. We use the system dynamics diffusion model to simulate the adoption process, and set up some situations to conduct scenario analysis. Finally, we make some suggestions and alternatives according to the simulation results.

Media storage formats have experienced some remarkably major transformations in the course of the development, including cassettes in1963, VHS in 1976, CDs in 1982, VCDs in 1993, and DVDs in 1996. Nowadays, existing DVDs have gradually failed to meet consumers'' demands for higher audio/video quality, so there is an inevitable trend for the invention of next-generation media format. As a company aiming at pursuing better format of multimedia entertainment, SONY invents the high-capacity and top-notch Blu-ray Disc to integrate the market. In the tug of war over new media formats between SONY''s Blu-ray Disc and Toshiba''s HD DVD, SONY cooperates with other computer and electronics companies to become SONY-led consortiums. In addition, SONY''s PlayStation 3, equipped with Blu-ray Disc player, also increases its market share and attracts more allies, which leads to the victory over his rival, Toshiba''s HD DVD. In order to provide a deeper insight into the media format market, this research reviews the development of media format, discusses SONY''s experience in media products, and scrutinizes BD''s current market condition and SONY''s financial statement in recent years. If we examine the sales statistics of Blu-ray Disc and DVD, we will find BD takes more than 10% market share in the whole disc business. Thought PlayStation 3, which comes with a built-in BD player, loses its prominent role in video game consoles, it is the determinant factor leading to the victory in the disc format battle. This study analyses Blu-ray''s competitiveness in the fourth chapter. By employing the definition of Value Net, this research examines the role BD plays in the next-generation media format and then investigate its SWOT, such as its strengths, weaknesses, opportunities, and threats to give proposals for its future development. To SONY, the first and foremost priority is to lower the cost of BD players, combine its resources and provide integrated multimedia service; in addition, to develop large-scale industry alliance and expand Blu-ray Discs application.

Reed-Solomon (RS) Codes has an important characteristic that can correct the Burst Error, thus it is applied in newly high capacity and high speed Address in Pre-groove (ADIP) in Blu-ray Disc (BD). In the high decoding speed application, as Blu-ray Disc, the bottleneck of RS decoder is finite field multiplier (FFM). In this thesis, we focus on the high speed FFM design under Normal Base. Using full-custom design methodology, we design the parallel architecture of RS decoder with high speed multi-input XOR, and our new FFM can work up to 1-GHz. We adopt this new high speed FFM in a Blu-ray Disc RS decoder, the simulation results confirms the effective of our work.

With the progress in technology and high-definition image development, in order to grab the huge share in video market, most of vendors keep launching new products and technology to fulfill customers’ expectation. Large size is not the only criterion for LCD TV and PDP TV. Now customers pay more attentions on high-definition image & video. Current DVD cannot meet customers’ requirement anymore. Under this circumstance, there are more demands for Blu-ray technology. Recently, BD Player has become hot and potential products in consumer-electronics market for its excellent support in high-definition video/image, multiple audio format and higher storage capacity, up to 50GB. The format of Blu-ray disc had been confirmed on 2008. It is estimated that with the release of final format, the market of BD player will be definitely blossom. The purpose of this study is to understand what kind criterions are crucial to customers for BD player. Based on these criterions, this thesis would like to confirm whether lifestyle can be used as the segmentation to distinguish target customers. By having proper description for the target customers in different segments, it is hope that this thesis can provide some valuable information and reference for vendors in their marketing strategy. The Study adopts Roger’s “innovation adoption process” model as basis. AIO lifestyle variable is used as the basic structure for market segmentation; then, input another two variables, product property and population statistics, for the evaluation. By doing so, we are examining whtehre there is any siginificant difference between consumers’ characteristics and their behaviors. The study objects are residents in Taipei area. Based on the study result, potential consumers for BD Player can be divided into three groups: “pinch pennies”, “pragmatic” and “social”. There are significant differences for each group in population statistics, information source, function preference, interest, and criterions for product property. Keywords: Life style, Blu-ray Disc Player, Innovation adoption, Market Segmentation.

To respond to the demands for the storage of high definition television(HD-TV) and various digital data, Sony and Toshiba respectively developed a new generation of blu- ray storage system, Blu-ray Disc (BD) and High Definition DVD (HD-DVD), to compete with each other. Once the specifications are unified, will they be accepted by the consumers? We would like to know how both companies compete in specifications and the factors of subsequently affecting consumer purchase. In this study, we use case study analysis to explore the competition process of blu-ray system specification, and then apply semi-structure interview to interview those stores in southern Taiwan who sell blu-ray system products, to understand the influence factors of consumers purchasing innovative BD products. The results of this study are as follows: 1.Through movie industry, video game machine business and channel business, Sony won and unified blue-ray system. 2.Empirical researches found the critical influence factors of consumers purchasing BD products are price, compatibility, channel, promotion, relative advantage, and product function etc. 3.BD system will be developed toward 3D in the future. But it does not meet current consumers’ expectation. And the last, this thesis presents the suggestions and the future researches based this study.
