Fast and adaptive browsing state recovery for multimedia consumer electronics devices

Most multimedia consumer electronics (CE) devices, such as smart phones, MP3 players, PMPs, and digital cameras, allow users to search and browse multimedia contents stored in the device. For multimedia CE devices, there are two important requirements: (1) the search results displayed in the browser screen must be restored when the device is turned off and later turned back on, and (2) the search results displayed in the browser screen must be updated dynamically to reflect data changes made by other applications. These two requirements have been handled in rather ad-hoc and inefficient manners until now. In this paper, we propose an efficient and systematic solution to meet the two requirements. The proposed solution enables us to save the current browsing state so that the search results displayed in the browser screen can be restored instantly at a later time. Furthermore, the proposed solution restores the browsing state adaptively to reflect data changes made after saving. Through performance evaluation in a real multimedia CE device, we show that the proposed method provides excellent performance compared to existing methods.

I. Introduction

Multimedia Consumer Electronics (CE) devices, such as smart phones, MP3 players, PMPs, and digital cameras, are electronic equipments that are daily used to create, store, and play multimedia contents. Multimedia CE devices store a large number of multimedia contents, and provide users with the ability to search and browse multimedia contents stored in the devices [1].
