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).

The present invention relates to an apparatus and a method of generating compressed data that compresses and encodes imputted data and outputs the compressed data generated through the compression and encoding process to communication media.
Advances in digital techniques have allowed practical utilization of a multimedia system. The multimedia system is defined as a system for integrational handling of multiple representation media (video data, audio data, additional data and so on) with a single communication medium (a telecommunication medium, a storage medium, a broadcast medium and so on).
The multimedia system includes a digital video disk (DVD) authoring system and a digital satellite broadcasting system. The DVD authoring system is a system for recording multiple representation media such as video data (referred to as ‘material data’ in the following description) in a unified form on a single DVD (a storage medium). The digital satellite broadcasting system is a system for broadcasting program data of multiple channels (data made up of a plurality of material data) in a unified form through a single communications line (a broadcast medium).
Other and further objects, features and advantages of the invention will appear more fully from the following description with reference to accompanying drawings.
FIG. 1 is a block diagram of an apparatus for generating compressed data of a first embodiment of the invention.
FIG. 2 is a flowchart showing a process of a CPU of the first embodiment.
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
A first embodiment of the invention will now be described in detail. The first embodiment allows compressed data generated through a compression and encoding process of a means for compression and encoding to be transferred to a means for data output through a data transfer line. The transfer process is controlled through a transfer control line other than the data transfer line.
FIG. 1 is a block diagram showing a configuration of the first embodiment. FIG. 1 illustrates an output of compressed data generated through a compression and encoding process to a storage medium wherein the compressed data is outputted to the storage medium as it is.
