					Flexible Movie Player Video/Audio Playback Software Achieves High-
Performance Video Processing on the SH-Mobile Application Processor for
Mobile Phones

⎯ Delivers high quality video playback even under high CPU load conditions ⎯



Tokyo, April 24, 2008 — Renesas Technology Corp. today announced the development of the Flexible
Movie Player video/audio playback software package for embedded systems using the SH-Mobile*1
application processor for mobile phones. The software will be available from July 2008 in Japan.

Flexible Movie Player is software designed for the SH-Mobile, which incorporates full hardware
acceleration supporting the H.264/MPEG-4 AVC*2 (referred to below as “H.264”) video compression
standard. It more efficiently extracts the video processing performance of the SH-Mobile than the video
playback middleware previously released by Renesas Technology. In particular, Flexible Movie Player
can deliver high-quality video reproduction even of content requiring high-volume processing by the
CPU. With earlier middleware video processing performance would have suffered when playing such
content due to the priority given to audio processing.

In addition, support for playback of MP4 video files, which are widely used on mobile phones, is
provided as standard, and modules are available for extending support to newer file formats in the
future. This makes it possible for mobile phone handsets to provide high-quality playback of multiple
types of video content. This modular structure provides flexibility in expanding functions and shortens
the system development time.



< Product Background >

In recent years the types of processing required of CPUs in mobile phone handsets in order to play
video content have proliferated as screen sizes have increased, data compression rates have risen, and
the need to reproduce original content has grown. Renesas Technology currently offers video playback
middleware for the SH-Mobile that supports playback of MP4 files only. This middleware gives
priority to the audio portion of the content during playback in order to minimize dropouts. This
sometimes results in a drop in video quality when the number of frames output per time unit decreases.

To deal with this problem, Renesas Technology reevaluated the audio-first processing system used in
the existing video playback middleware and decided instead on a new audio-video independent
processing system when developing the Flexible Movie Player software. This ensures high-quality
playback of MP4 files, with no audio dropouts and no reduction in the video frame rate.

< Features >

The features of the Flexible Movie Player video/audio playback software for SH-Mobile are
summarized below.

(1) High-quality video reproduction even during high CPU load situations
    Flexible Movie Player does a better job of extracting the full performance of the SH-Mobile’s full
    hardware acceleration and digital signal processor (DSP) because it uses an audio-video
    independent processing system. For example, with VGA-size content recorded at 30 fps (frames
    per second) and combining H.264 video and audio compressed in aacPlus*3 format, the number of
    frames output per time unit decreases in the existing middleware due to the priority given to audio
    processing. But Flexible Movie Player achieves a dramatic improvement in video processing
    performance, boosting the maximum frame rate (frames per second) by 30% over that achieved by
    the existing middleware. Thus, there is no drop in video processing performance, even with
    content, such as higher quality video, that imposes a large processing load on the CPU, and high-
    quality video reproduction is achieved.

(2) Improved file format extensibility for reduced system development time
    Flexible Movie Player has a modular structure that allows new functionality to be added later. It
    allows a file format to be extended by developing and incorporating additional modules supporting
    this software. This makes it possible to meet the needs of a wide range of customers and helps
    shorten the system development time.
    The existing video playback middleware from Renesas Technology must be used in combination
    with the MP4 file operation middleware, also supplied by Renesas. In contrast, Flexible Movie
    Player can be used in combination with middleware developed by the customer, in addition to
    middleware from Renesas Technology (file operation middleware and codec middleware).

(3) Enhanced flexibility for adding future content types and new system elements
    The modular design will make it possible to provide support for future decoder and new systems
    more flexibly and quickly. For example, mobile phone handset embedded display systems are
    expected to increase in definition from the present VGA to standard definition (SD) and then
    eventually high definition (HD). When this occurs, it will be possible to provide support for the
    new codecs required to implement the higher level of compression and decompression by adding a
    module. This will make it possible to develop new systems in less time and enable manufacturers
    to bring new products to market in a timely manner.
    Compared with the amount of time it previously required Renesas Technology to develop software
    to support a new codec, it takes about half the time to develop a new module.

As the functions of multimedia applications for mobile phones continue to become more sophisticated,
Renesas Technology plans to continue developing software solutions such as middleware for video
playback in response to market demand.
