In the 21st century mobile phones are in everyone's pocket and handbag. The main reason for this is that the multimedia processors were used in mobile phones. This paper is about the multimedia processors in mobile technology. This was impossible many years ago, but it is possible now in applications that can be implemented effectively and many mobile phone applications have changed people's lives. These technological applications developed so far are easy and useful. This paper describes the multimedia processors in Nokia and iPhone's products in 2008-2009 and compares these two brands' advantages and disadvantages.

Multimedia Processors

Multimedia can be defined as 'text, images, audio and video, considered as a group' ¼ˆHalsall 2001: 1¼‰. The multimedia processors can be described as the product has many functions which are used as multimedia. A mobile phone is one of the most remarkable multimedia processors.

Functions in mobile phones

In the end of the twentieth century, the mobile phones only with word or voice were not enough for us. People were looking for something new that could be used as a multimedia processor. Some mobile companies such as Nokia, Motorola, Sony Ericsson and Apple found the opportunity to make a mobile phone much more function.

Take an example: a system called SMC (Smart Mobile Client). Every customer can be identified through the Bluetooth-enabled phone. SMC can locate the shoppers and products, providing directional information. Speech technology is incorporated into SMC to provide interactivity with users. Customers could also acquire information through SMC. SMC helps visitors to find the location where they want to go. The system is installed in the user's mobile phone. With the help of GPS and Bluetooth, SMC provide the correct and most convenient way to the destination (Lim, 2005).

Multimedia Processors in Mobile Phones

Nokia's multimedia processors (2008-2009)

Nokia is one of the largest manufacturers of mobile phones in the world. In 2008-2009, they produced about 50 new products. Furthermore, there are three products which include all the characteristics of the new phones of this period: the Nokia 5800i, the Nokia E71 and the Nokia N97. First of all, the Nokia 5800i is the latest of these three products and it has been introduced for the young and trendy crowd. The multimedia processor in the Nokia 5800i focuses on the entertainment function and includes online shopping. Therefore, the Context-Aware Retail System (CARS) is applied in. CARS is a shopping inquiry system which can help people to find out a product's price and location. CARS is an intelligent system that can provide customers with personalized service which can be according to the environment and users to change its behavior (Lim, 2005).

Secondly, the Nokia E71 and the Nokia N97 are suitable for business people. For instance, these can send E-mails and write messages more effective by a new multi-function input method. Furthermore, the Nokia N97 supports 3G network which has broadband ISDN that supports multimedia communication applications involving text, high-resolution images, speech, audio and video (Halsall, 2007: 646).

iPhone's multimedia processors (2008-2009)

In the 3G era, mobile phones, not only support voice and circuit-switched data transmission, also support packet-switched data required for multimedia applications (McDonald, 2009). iPhone's 3G was appeared in late 2008. Compare to Nokia, iPhone just had few products during this year, the iPhone 3G and the iPhone 3GS. Obviously, iPhone is not have many products but it suitable for all kinds of people. iPhone has the most functions and also includes improved technology: it combined with larger screens that responded to a touch. More exactly, "usability" is the key word. iPhone supplys a reasonable Web experience by pushing one button. iPhone has a special system such as Apple's laptops which can support many third-party software. It made iPhone more flexible and entertaining (McDonald, 2009).

Nokia and iPhone


There are many merits of multimedia processors which are used in mobile phones. In the first place, CARS, which was used by Nokia that location tracking is one of the key technologies. The technology tested the indoor location tracking capability. The technology tested the outdoor location tracking capability. The technology tested the integration of indoor and outdoor location tracking capability. In all the technologies, the system was able to respond appropriately based on the contextual information (Lim, 2005). The system also integrates gaming, education, and several mobile technologies to create a new mobile guiding and gaming system, which is used for tourists to explore and learn an exciting and fun way. The system is people-centered, intelligent, and offers travelers a interesting experience (Lim, 2005).

A passenger checking in for a flight departing from Tokyo, he can comply with Japan's check-in rules but use English to complete this process (McDonald, 2009).

Finally, the Nokia N97 includes almost all the popular features. Relative to the iPhone 3GS, the Nokia N97 increases a slide-out keyboard yet , which makes the customers input messages effectively.


In Nokia' products, there are many models for people to choose, but not all models are suitable for everyone. Sometimes it is difficult to make a correct choice. Furthermore, many functions in multimedia processor make the phone's power consumption is very large. People have to spend more money to buy another battery. In iPhone' products, excessive battery consumption is also a serious problem. The main reason for this is the multimedia processor cannot control their frequency effectively in different functions.

This paper has defined an overview of the multimedia processors in mobile phones, focussing on explanation the functions of multimedia processors. It has also compared Nokia and iPhone's products in 2008-2009. Then, it has introduced the advantages and disadvantages of these two brands as well as chose a best product. These findings explain the excessive battery consumption is the same shortage from all advanced phones. The benefits of iPhone's products are various, they are suitable every kinds of people. Nevertheless, all mobile phones we have seen so far have one thing in common: they are used for people. Mobile phones must be user-centered design. No feature should be added to mobile phones only because it is cheap and easy.
