Abstract

The present invention relates to a mobile set integrating a memory efficient data storage system for the real time recording of voice conversations, data transmission and the like. The data recorder has the capacity to selectively choose the most relevant time frames of a conversation for recording, while discarding time frames that only occupy additional space in memory without holding any conversational data. The invention executes a series of logic steps on each signal including a voice activity detector step, frame comparison step, and sequential recording step. A mobile set having a modified architecture for performing the methods of the present invention is also disclosed.

Claims

1. A computer-readable medium containing instructions for controlling a mobile set processor to record multimedia signals, comprising:

controlling a voice activity detector to compare a plurality of voice signals having identical time stamps and arranging the voice signals such that data containing time stamp sequences are arranged sequentially into a single data file;

controlling a processor to identify non-voice signals containing the same time stamp as data containing voice time stamp sequences; and

sequentially recording the data containing voice signals and the corresponding time stamp non-voice signals such that both the voice and non-voice data signals are sequentially recorded into a memory element as a single data file.

2. The computer-readable medium of claim 1, wherein the non-voice data sequences are video data.

3. The computer-readable medium of claim 1, wherein the non-voice data sequences are text-messaging data.

4. The computer-readable medium of claim 1, wherein the non-voice data sequences are e-mail data.

5. The computer-readable medium of claim 1, wherein the voice activity detector is a processor.

6. The computer-readable medium of claim 1, wherein the voice activity detector compares voice signals from an uplink connection and a downlink connection.

7. The computer-readable medium of claim 1, wherein the processor identifies non-voice signals from an uplink connection and a downlink connection.

8. A system for controlling a mobile set processor to record multimedia signals, the system comprising:

at least one processor that enables controlling a voice activity detector to compare a plurality of voice signals having identical time stamps and arranging the voice signals such that data containing time stamp sequences are arranged sequentially into a single data file;

said at least one processor enables identifying non-voice signals containing the same time stamp as data containing voice time stamp sequences; and

said at least one processor enables sequentially recording the data containing voice signals and the corresponding time stamp non-voice signals such that both the voice and non-voice data signals are sequentially recorded into a memory element as a single data file.

9. The system of claim 8, wherein the non-voice data sequences are video data.

10. The system of claim 8, wherein the non-voice data sequences are text-messaging data.

11. The system of claim 8, wherein the non-voice data sequences are e-mail data.

12. The system of claim 8, wherein the voice activity detector is a processor.

13. The system of claim 8, wherein the voice activity detector compares voice signals from an uplink connection and a downlink connection.

14. The system of claim 8, wherein the at least one processor identifies non-voice signals from an uplink connection and a downlink connection.
