CELL REGZATM—The Innovative LCD TV
CELL REGZATM Realizing All Future Possibilities of TV
Trends in High-Performance and Multifunction Flat-Panel TV Technologies and CELL REGZATM
With the wide dissemination of digital high-definition (HD) broadcasting in recent years, flat-panel TVs including those equipped with a liquid crystal display (LCD) have become more common. To overcome competitors and survive in the market, it is necessary to implement outstanding evolution by developing products with high performance and functionality in addition to basic functions such as reception of digital HD broadcasts.
Toshiba has developed the REGZATM LCD TV series of high-performance multifunctional TVs featuring high-level picture quality powered by an image-processing engine, as well as network and hard disk drive (HDD) recording functions. The CELL REGZA, released in December 2009 as the flagship HDTV of the REGZA lineup, reaches the highest state of development of high-performance multifunctional TVs due to the incorporation of the Cell Broadband EngineTM high-performance multicore processor, which makes it possible to not only refine the performance but also acquire new functions by means of software updates.
CELL PlatformTM Expanding Limits of TV Performance

Toshiba has developed the CELL Platform, which serves as the heart of the CELL REGZATM flagship high-definition (HD) TV of the REGZATM lineup. Incorporating the Cell Broadband EngineTM (abbreviated as Cell BE) high-performance multicore processor, the CELL Platform supports innovative high resolution as well as high sound quality, recording technology, and network technology. It is composed of three boards: a Cell BE board consisting of the Cell BE, interface large-scale integrations (LSIs), and main memories; an HDTV function board; and a light-emitting diode (LED) backlight control board.
The combination of the CELL Platform with 13 digital tuner units and 3 Tbyte hard disk drive (HDD) units makes it possible to offer viewers new value, including remarkably high picture and sound quality, multichannel HDTV viewing and recording, and networking functions.
"Mega LED PanelTM" Reproducing Jet Black and Sparkling White on CELL REGZATM

Demand has been growing in recent years for liquid crystal display (LCD) TVs that can reproduce high-definition (HD) digital images of higher quality.
With this as a background, Toshiba has developed the Mega LED Panel featuring a light-emitting diode (LED) backlight with local dimming technology, and introduced it into the CELL REGZA, the flagship HDTV of the REGZATM lineup. The CELL REGZA with the Mega LED Panel achieves a peak luminance of 1,250 cd/m2, which is 2.5 times brighter than conventional LCD-TVs, and a dynamic contrast ratio of 5,000,000:1. The CELL REGZA offers viewers state-of-the-art picture quality with jet black and sparkling white color reproduction.
Advanced Super-Resolution Technologies of CELL REGZATM

The image resolution of DVD contents and online contents distributed via the Internet is often lower than that of full-high-definition (HD) contents (1,920 x 1,080 pixels). To overcome the poor quality of image edge details using conventional technologies based on linear upscaling, Toshiba has developed a super-resolution technology that achieves high-quality HD images and released the REGZATM series of HD televisions (HDTVs) incorporating this technology.
We have also developed the CELL REGZA, the flagship HDTV of the REGZA lineup, which offers images superior to those provided by existing HDTVs through the following advanced super-resolution technologies installed on the high-performance CELL PLATFORMTM: (1) super-resolution technology for Internet video, (2) super-resolution technology using self-congruency, and (3) super-resolution technology for color components.
"Time-Shift MachineTM" Allowing Recorded Programs to be Shown like Real-Time Broadcasting
The CELL REGZATM, released in December 2009 as the flagship high-definition (HD) TV of the REGZATM lineup, features unprecedentedly high resolution and high sound quality, unprecedented recording functionality, and unprecedented network capability.
With regard to the recording functionality, the "time-shift machine" is a key function that allows up to approximately 26 hours of programming to be simultaneously recorded from up to eight digital terrestrial broadcast channels. The time-shift machine offers viewers a new audiovisual experience, transforming the mere receiving of previous programs into the new discovery of programs.
High-Performance Audio Technology of CELL REGZATM

As the flagship high-definition (HD) TV of the REGZATM lineup, the CELL REGZA is aimed at realizing not only high performance but also the highest quality from every point of view, including image quality, design, and functionality. However, it was difficult to achieve high-quality sound due to the dimensional restrictions in the development of flat-panel HDTVs.
To rectify this situation, Toshiba has developed an audio system with a new innovative concept giving highest priority to the sound quality. Almost the same level of sound quality as in a high-grade audio system is realized by a newly developed speaker system and multichannel digital amplifier. Moreover, the CELL PlatformTM at the heart of the CELL REGZA system incorporates a content-based adaptive audio enhancement control function that provides real-time sound processing suitable for movie scenes.
"Roaming NaviTM" Content-Centric User Interface

Users are increasingly demanding a means of performing effective searches for media contents of interest to them from among the enormous volume of broadcast and Internet contents available, instead of the conventional list-based type of graphical user interface.
In response to this need, Toshiba has developed Roaming Navi, a relevance-driven content search system utilizing a content-centric user interface based on relationships among media contents to access or find new media contents of interest to the user. Relevant contents are displayed on the screen according to the relevance information, with the distance and direction of the relevant content from the center content indicating the strength and attribute of the relevance, respectively. We have also developed a feasible relevance calculation scheme based on user evaluation tests, and confirmed its effectiveness.
Stroke Recognition Technology for Touchpad on CELL REGZATM Remote Controller

Toshiba has developed a novel stroke recognition technology for the CELL REGZA remote controller, which is equipped with a touchpad. This stroke recognition technology incorporates two recognition techniques: one for recognizing handwritten characters, and the other for recognizing gestures from strokes made by the trajectories of the user's finger on the touchpad.
This technology allows the CELL REGZA to offer an easy and intuitive means of controlling TV functions such as pointer control for Internet browsing and character input for TV program search, which users often find troublesome when they use a conventional remote control with push buttons.
Software of CELL REGZATM

The CELL REGZA, Toshiba's leading-edge LCD TV, incorporates the Cell Broadband EngineTM (abbreviated as Cell BE) high-performance multicore processor and offers new features that have never been realized by conventional TV sets. To realize key features including multiple display, electronic program guide (EPG) with moving pictures, and high-speed channel tuning, the software structure of the CELL REGZA is dynamically changed by making effective use of its computing power and memory. The CELL REGZA also has the capability to acquire new functions by software updates.
Improvement of GUI Development Environment for CELL REGZATM

Sophisticated, user-friendly graphical user interfaces (GUIs) are required to enjoy the high performance of the CELL REGZA, the flagship high-definition (HD) TV of the REGZATM lineup.
In order to improve the efficiency of GUI development for the CELL REGZA, Toshiba has established an appropriate environment for GUI development comprising an automated GUI design converter that can automatically convert GUI designs into GUI resource data, a unified GUI framework that offers an application program interface (API) for event handling and animation, and a memory leak checker library as well as customizable test tools that make a significant contribution in the testing phase. These features have been shown to be effective in improving the GUI development environment for the CELL REGZA.
