Abstract

The present invention relates to a data CODEC system for computer. The data CODEC system for computer comprises a system control software, a multichannel audio/speech and multimedia data signal processor, and a multichannel audio/speech and multimedia data input-output unit. The system control software communicates multichannel audio/speech and multimedia data with the multichannel audio/speech and multimedia data signal processor according to control of various application programs. The multichannel audio/speech and multimedia data signal processor processes multichannel audio/speech and multimedia data. The multichannel audio/speech and multimedia data input-output means inputs/outputs multichannel audio/speech and multimedia data from/to an external system.

Claims20

Dependent claims

A data encoder/decoder (CODEC) system for use in a host computer to control signal processing operations, including encoding and decoding multichannel audio/speech and multimedia data, the data CODEC system comprising:

a system control software section arranged to communicate with one or more application programs stored in storage media of the host computer;
a signal processing section arranged to control signal processing operations, including encoding and decoding multichannel audio/speech and multimedia data under control of the system control software section;
and
an input-output section arranged to input multichannel audio/speech and multimedia data from an external system, and to output processed data to the external system;
wherein said system control software section communicates multichannel audio/speech and multimedia data with said signal processing section under control of said application programs;
and
wherein said signal processing section processes multichannel audio/speech and multimedia data using said application programs under control of said system control software section.

4 more elements

A data encoder/decoder (CODEC) system installed in a host computer, comprising:

a system control software section arranged to communicate with one or more application programs stored in storage media of the host computer;
an input-output section arranged to receive data from an external device, and to output processed data to the external device;
and
a signal processing section arranged to receive data from one of an application program and the external device, via the input-output section;
to control signal processing operations, including data encoding and data decoding in accordance with the application program;
and to transmit processed data to the application program for storage in the storage media or to the external device, via the input-output section,
wherein the system control software section loads the application program from the storage media, activates operations of the signal processing section and the input-output section, generates system status information to the application program, and transmits data stored in the storage media to the signal processing section and processed data from the signal processing section to the application program for storage in the storage media.
