Abstract

A navigation system written in J2ME MIDP for a client device includes a plurality of media players each respectively comprising a buffer. A navigation program manages the state of the plurality of media players. The plurality of media players are in either one of an acquiring resources state, and a playing and de-allocating state. The use of a plurality of media players each respectively comprising a buffer overcomes the prior art in which navigation system can cut off a voice prompt because of the time-consuming tasks associated with playing a voice prompt.

Claims

1. A navigation system for a client device, comprising:

a plurality of media players each respectively comprising a buffer, and each having an acquiring resources state, and a voice prompt and de-allocating state; and

a navigation program to manage said acquiring resources state and said voice prompt and de-allocating state in each of said plurality of media players.
