Renesas! SH-Mobile to achieve a high-performance video processing software!

Anh em chuẩn bị tinh thần cho series 906i sắp ra lò nha.., playback High Definiton Video. Không còn gì để nói

Application processor for mobile phones "SH-Mobile" high-performance video processing in the movie playback software to achieve a "Flexible Movie Player" to complete development

CPU high-load conditions, to achieve high-quality video playback

Renesas Technology, Inc. (Nasdaq: Chiyoda-ku, Tokyo, President & CEO: Susumu Itoo) today announced a mobile phone application processor "SH-Mobile" (1) use a system built for movie playback Software "Flexible Movie Player" (flexible movie player). From July 2008 to start.

"Flexible Movie Player" is a video compression standard H.264/MPEG-4 AVC (Note 2) (collectively, H.264) with the full hardware "SH-Mobile" software, DEKODOMIDORUUEA Decode at (decrypt) the value, while output synchronized to take control. Our traditional "video-play middleware" than, AV independent process in the adoption of the scheme, "SH-Mobile" from the performance of video processing efficiently inputs. In particular, require large amounts of CPU and the content of the traditional preference for the voice processing performance video processing of the cases, the "Flexible Movie Player" has shown no deterioration in image quality, high-quality Video playback can be achieved. (Specific examples are discussed below Features (1) please refer)

The mobile phone is widely popular video files to the MP4 file to play the standards, but will respond to the new file format for the entire system without major changes to the corresponding module to add Only a variety of high-quality video content from playing. Therefore, the extension of flexible response system and development time can be reduced.

In recent years, mobile phone video content play in the big-screen content, data compression ratio improved to reproduce the original data and to improve the process is more CPU has been required. We have already, "SH-Mobile" for playing MP4 files for "video playback middleware" is to provide the content of the sound when playing out of avenues to reduce to a minimum, voice and data to prioritize the regeneration process Because the system, the CPU requires a large amount of content, image and data replay, the output per unit of time by decreasing the number of images, video quality is reduced if the session.

Such problems, the content playback system to review and independent process for new AV adoption of the system, the CPU plenty of time to break someone's voice without having to display images without lowering the number of high-quality MP4 files achieve the rebirth of "Flexible Movie Player" to develop.

Features

"SH-Mobile" for a movie playback software "Flexible Movie Player" features are listed below.

（1） CPU in the high-load conditions to achieve high-quality video playback DSP（Digital Signal Processor） Our traditional "video-play middleware" in comparison with, AV independent process in the adoption of the scheme, "SH-Mobile" is the full-chip hardware and DSP (Digital Signal Processor) can draw from the performance Possible.

For example, play the content, image compression method is H.264, audio compression method is aacPlus (Note 1), VGA image size is the size and number of images per unit of time is 30 fps (frame per second) recorded by TEITA, audio break out without improved performance video processing and up to 30% compared with our conventional frame rate (the number of frames per second process) to improve. Thus, high-quality video content has increased the CPU is necessary in many cases, audio video processing without performance degradation, high-quality video playback possible.

（2） File format for increased scalability, the system can shorten development time

"Flexible Movie Player" is a modular approach and has added the software to support the development of additional modules include only the file format can be extended. Because of the wide range of customer needs and available, the system has also reduced development time.

In addition, our traditional "middleware video replay" of the Company's "MP4 file operations middleware" used in combination it was necessary, although "Flexible Movie Player" has made our middleware ( "middleware file operations" and "KODEKKUMIDORUUEA") and other combinations, customers are also supported the development of middleware.
(3) Future codec and add flexibility when adding new systems to improve

Additional modules based on the future, add new codec support and response systems are also diverse, more flexible, and short-term achievable.
For example, embedded systems expected to be VGA display size SD (Standard Definition) size, HD (High Definition) to the size of high-definition, high performance compression and decompression codec to deal with new and additional modules. In order to allow the system to shorten development time and achieve timely market.

Add new codec support, we period of the traditional software development, the development of modular add about half of the period is shortened.

We will continue to support multimedia applications for mobile phones with advanced functions, video playback and the development of middleware, and from high-quality, high-definition video playback, such as development of market needs solutions.
