1. A mobile set, comprising:
- a memory; and
a processor that is operatively coupled to the memory,wherein the processor supports a display of a plurality of recording modes, wherein each of the plurality of recording modes records a different set of data frames exchanged between the mobile set and a second device during a phone call, wherein one of the displayed recording modes is chosen, wherein the processor records, in the memory, a set of data frames according to the chosen recording mode, wherein the recorded set of data frames comprises a downlink voice signal, a downlink video signal, an uplink voice signal and an uplink video signal, wherein the downlink video signal is recorded in the memory when the downlink voice signal is determined to have voice activity, and wherein the uplink video signal is recorded in the memory when the uplink voice signal is determined to have voice activity.

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.

8. A mobile set, comprising:
-
a memory; and a processor that is operatively coupled to the memory, wherein the processor supports a display indicating a data structure of recorded conversations, wherein the recorded conversations comprise uplink data frames transmitted from the mobile set to a second device during a phone call and downlink data frames transmitted from the second device to the mobile set during the phone call, wherein the uplink data frames comprise uplink voice signal frames and uplink video signal frames, wherein the downlink data frames comprise downlink voice signal frames and downlink video signal frames, wherein the uplink data frames and the downlink data frames are selectively recorded in the memory based on a data content analysis, performed by the processor, of each uplink data frame and each downlink data frame, wherein the uplink video signal frames are recorded in the memory when the uplink voice signal frames are determined to have voice activity, wherein the downlink video signal frames are recorded in the memory when the downlink voice signal frames are determined to have voice activity, and wherein, in response to a selection of the displayed line, the processor replays a recorded conversation. - View Dependent Claims (9, 10, 11, 12, 13)

14. A first mobile set, comprising:
-
a memory; and a processor that is operatively coupled to the memory, wherein the processor supports a display that indicates data structures representing recorded conversations, wherein the recorded conversations comprise uplink data frames transmitted from the first mobile set to a second mobile set during a phone call and downlink data frames transmitted from the second mobile set to the first mobile set during the phone call, wherein the uplink data frames comprise uplink voice signal frames and uplink video signal frames, wherein the downlink data frames comprise downlink voice signal frames and downlink video signal frames, wherein the uplink data frames and the downlink data frames are selectively recorded in the memory based on a data content analysis, performed by the processor, of each uplink data frame and each downlink data frame, wherein the uplink video signal frames are recorded in memory when the uplink voice signal frames are determined to have voice activity, wherein the downlink video signal frames are recorded in memory when the downlink voice signal frames are determined to have voice activity, and wherein, in response to a selection of a particular data structure of the data structures, the processor replays at least a portion of the particular data structure. - View Dependent Claims (15, 16, 17, 18, 19, 20)
