A Model for the Transmission of Multimedia Data Flow Based on the Use of Shared Memory Mechanism

The communication between multimedia components located on the same physical machine, but in different address space, uses mechanisms designed for distributed environments. The present paper proposes an inter-component communication model in this context through the use of a shared memory mechanism. This model is based on the shared memory primitives offered by different operating systems. The model can be used in different middleware platforms. To evaluate the model, an application written in Java was developed, that, through functions written in C language, has access to the primitives of manipulation of the shared address space.
