London, 29th April, 2009 — Renesas Technology Europe today announced the
SH-MobileHD1 application processor for mobile phones (product number: SH7370), the first in the industry to deliver Full High-Definition (1,920 × 1,080 pixels, abbreviated “Full HD”) video recording and playback support.

The video processing unit of the SH-MobileHD1 delivers approximately six times the performance of comparable earlier products from Renesas Technology, enabling support for Full HD video on a single chip. In addition to the low power consumption essential for mobile phones, the new application processor also features more robust multimedia functionality. It is available in a small package designed to facilitate more compact video and audio processing systems for mobile phones.

The device supports the H.264/MPEG-4 AVC*1 video compression standard (H.264) at Full HD video resolution with a playback/recording frame rate of 30 frames per second (fps). With a maximum operating frequency of 500 MHz, the IC is approximately twice as fast as earlier comparable Renesas Technology products. The SH-MobileHD1 incorporates two 24-bit dedicated audio DSPs to lighten the audio processing load on the CPU and reduce power consumption. This enables one DSP to handle (stereo) audio processing such as the AAC (Advanced Audio Coding) high-quality audio compression standard and Dolby Digital codec, with power to spare, while the other DSP handles sonic enhancement such as equalization and sample rate conversion (SRC). In addition, heavy-load processing tasks such as 5.1-channel audio can be assigned to the dual DSPs. Support for Dolby Digital and 5.1-channel audio allow interoperation with applications designed for consumer audio components.

In addition, the IC includes an interface that supports connection to a transmitter microchip that implements the HDMI high-speed multimedia interface used for interconnections between AV components. This allows connection and output of Full HD resolution video to digital home electronics components such as LCD TVs or Blu-ray Disc recorders. In addition, the SH-MobileHD1 can connect to an SD memory card and wireless LAN (WLAN), and it supports multiplexing*2 of the MPEG2-TS (transport system) and MP4*3 formats. Since MPEG2-TS is rapidly gaining popularity as a multiplexing format for HD and Full HD video in the digital home electronics field, support by the SH-MobileHD1 enables easy sharing of content between digital home electronics products and mobile phones. When content is stored as MP4 files, it can be shared easily over a network such as a WLAN. This helps increase the usability of video applications.

The SH-MobileHD1 supports Full HD video but uses a compact 407-pin BGA package measuring 10 mm × 11 mm. The application processor and 512 megabits of synchronous DRAM (SDRAM) are integrated into a single package as a system-in-package (SiP) device for greater system compactness.

The SH-MobileHD1 also has a camera interface that supports direct connection to a 15-megapixel camera module. This allows high-speed importing of voluminous data from a high-resolution camera and makes possible a variety of display functions, including electronic zoom and superimposed effects such as an on-screen display (OCD) function or hardware cursor (HWC) function. There is also compatibility with BT.709 format YUV data as part the support for One-Seg TV broadcasts. This makes it possible to convert snippets of TV broadcast data to JPEG format with no degradation in image quality. The many on-chip peripheral functions suitable for mobile phone systems also include an LCD controller with support for 24-bit TFT color LCD panels and a sound interface.

  1. H.264/MPEG-4 AVC (Advanced Video Coding) is a video compression standard established jointly by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) and the international standardization organizations ISO/IEC.
  2. Multiplexed: As used in this press release, the term multiplexing refers to the synchronizing and combining of a video file and an audio file into a single file.
  3. MP4 format: A file format in which compressed video data, such as MPEG-4 or H.264, and compressed audio data, such as AAC, are multiplexed.
