Contents data processing device and method

Abstract

It is difficult to implement an arrangement for handling of contents data such as moving picture and audio data because of a need to ensure the desired bit rate, etc. In ordinary cases, therefore, a configuration dependent on hardware results and the portability of the system is low. A layered contents processing architecture improves the portability of the system and facilitates the development of application programs. In a case where part of devices are combined into an LSI, the layered architecture can also be applied to the LSI.

Description

technical field [0001] The present invention relates to software and hardware architectures for multimedia data processing. Background technique [0002] In recent years, multimedia data processed by a computer has been used for various purposes such as moving images and audio. For example, a device called a hard disk recorder that converts moving images such as television broadcasts in real time by a moving image encoder and records them on a hard disk, or records moving images as digital data on optical discs such as DVDs The content data is displayed on a player or the like on a video display device. Generally, in these content processing, it is necessary to read content data at a specified bit rate and process it within a certain period of time. It is important to be able to easily develop a program module that performs these complicated streaming processes in use, and therefore, there is a method of executing a program that performs content processing in the core of a...

Problems solved by technology

[0007] Since each platform has its own content data processing device, the development of a program using content must be performed for each OS or hardware configuration, resulting in an increase in the development process.
