Abstract
An apparatus comprising an encoder circuit and a transcoder circuit. The encoder circuit may be configured to generate a bitstream comprising a series of packets in response to a speech input signal. The transcoder circuit may be configured to generate an intermediate bitstream in response to the bitstream. The transcoder (a) implements (i) a first encoding type comprising a selectable mode voice (SMV) encoding or (ii) a second encoding type comprising an enhanced variable rate (EVR) encoding in response to a type of data in each of the packets of the bitstream and (b) the first or second encoding type is selected on a per packet basis.
Claims18
An apparatus comprising:
- an encoder circuit configured to generate a bitstream comprising a series of packets in response to a speech input signal;
- and
- a transcoder circuit configured to generate an intermediate bitstream in response to said bitstream, wherein said transcoder (a) implements (i) a first encoding type comprising a selectable mode voice (SMV) encoding when in a first mode and (ii) a second encoding type comprising an enhanced variable rate (EVR) encoding when in a second mode, in response to a type of data in each of said packets of said bitstream and (b) said first or second encoding type is selected on a per packet basis.
An apparatus comprising:
- means for generating a bitstream comprising a series of packets in response to a speech input signal;
- and
- means for generating an intermediate bitstream in response to said bitstream, wherein said means for generating an intermediate bitstream (a) implements (i) a first encoding type comprising a selectable mode voice (SMV) encoding when in a first mode and (ii) a second encoding type comprising an enhanced variable rate (EVR) encoding when in a second mode, in response to a type of data in each of said packets of said bitstream and (b) said first or second encoding type is selected on a per packet basis.
A method for transcoding comprising the steps of:
- (A) generating a bitstream comprising a series of packets in response to a speech input signal;
- and
- (B) generating an intermediate bitstream in response to said bitstream, wherein step (B) (a) implements (i) a first encoding type comprising a selectable mode voice (SMV) encoding when in a first mode and (ii) a second encoding type comprising an enhanced variable rate (EVR) encoding when in a second mode, in response to a type of data in each of said packets of said bitstream and (b) said first or second encoding type is selected on a per packet basis.
