Abstract
Compression and encoding sections (311 (1), 311 (2) and 311 (3)) compress and encode input signals VS, AS and SS separately to generate compressed data. A SCSI interface (32) outputs the compressed data to a DSM (50). Output buffers (312 (1), 312 (2) and 312 (3)), a stream interface (34) and an input buffer (33) transfer the compressed data generated at the compression and encoding sections (311 (1), 311 (2) and 311 (3)) to the SCSI interface (32) through data transfer buses (38 (1), 38 (2), 38 (3), 39 and 40). A CPU (35), a RAM (36) and a ROM (37) control data transfer through a CPU bus (42).
Claims14
An apparatus for generating compressed data comprising:
- a compression and encoding means for compressing and encoding input data and outputting the data;
- an output means for outputting the compressed data outputted from the compression and encoding means;
- a data transfer means for transferring the compressed data outputted from the compression and encoding means to the output means;
- and
- a control means connected to the compression and encoding means through a control bus for performing control for inputting the compressed data outputted from the compression and encoding means to the data transfer means based on control information from the control bus.
A method of generating compressed data comprising:
- a step of compressing and encoding input data by a compression and encoding means;
- a transfer control step of receiving control information on the compressed data compressed and encoded in the step of compressing and encoding through a control bus and controlling transfer of the compressed data based on the received control information;
- a data transfer step of transferring the compressed data compressed and encoded in the step of compressing and encoding based on the transfer control step;
- and
- a step of outputting the compressed data transferred in the data transfer step to outside.
