Cooperative Multimedia Playback Architecture for Pervasive Cellular Phones

Cellular phones as one of the necessities of life has been developed very rapidly, and various services for them are introduced. However, due to the insufficient hardware resources, multimedia services depend on special hardware devices which cause high manufacturing cost and high battery consumption. In this paper, we introduce a software-based multimedia playback architecture that can be used for multimedia services. To realize software-based scheme, we start from video partial decoding and VOCODER timer. With these two tools, we envision multimedia player architecture working with other existing tasks without any modification and without any special hardware device. In experiments, we show that software-base playback is really possible for pervasive cellular phones.
