Renesas announces video conferencing software for 3G phones

March 29, 2005

Renesas Technology announced the Mobile Videophone Middleware Package software, which adds a video conferencing capability to Renesas Technology's popular SH-Mobile(1) series of application processors. The new videophone software conforms to the 3G-324M(2) 3G mobile phone audiovisual (AV) communications standard and incorporates an echo-canceller function for mobile phone systems that use these application processors. Renesas SH-Mobile chips are the world's most popular co-processors for implementing multimedia functions in mobile phones.

The new software is available for the SH-MobileV2 device (type name: SH7310) and SH-Mobile3 device (type name: SH73180), both of which have built-in MPEG-4(3) full hardware accelerators. The software offers the following features:

(1) Capabilities that accelerate and simplify videophone application development

The Mobile Videophone Middleware Package software enables quick and easy development of 3G-324M compliant videophone functions in mobile phone systems that incorporate SH-Mobile application processors. It includes all of the processing functions specified in the 3G-324M audiovisual communications standard.

(2) Echo-canceller and noise-suppression functions that simplify phone designs

The software provides the echo-cancellation and noise-suppression functions that otherwise would have to be implemented by dedicated external chips. Eliminating these external devices reduces the cost of manufacturing mobile phone systems.

(3) An optimized signal-processing algorithm that allows the use of a low CPU operating frequency to save power

Algorithm optimization enables the capabilities of the MPEG-4 full hardware accelerator and DSP (digital signal processor) in SH-Mobile devices to be used to the fullest possible extent. With the Mobile Videophone Middleware Package software, the moving-image compression/decompression processing (15 frame per second) and voice compression/decompression processing can be implemented at a low CPU operating frequency, about 90MHz. This reduces system power consumption, helping to extend battery life of the phone.

Product Background

Mobile phone systems are offering more and more advanced multimedia capabilities, such as games and moving images. One trend is to incorporate videophone functions in 3G mobile phone systems. However, videophone applications require multiplexing operations, protocol processing and other tasks, besides moving-image voice compression/decompression processing. This necessitates a great amount of development work.

The Mobile Videophone Middleware Package software from Renesas Technology eliminates the need for phone designers to perform this development. The software provides the single-function middleware items essential for developing 3G mobile phone systems with videophone functions. It also offers valuable features such as 3G-324M compliance and an echo-canceller function.

The Mobile Videophone Middleware Package software will be available in May 2005.
