Embodiment Construction

[0033] Various embodiments of the present invention will be described below with reference to the accompanying drawings.

[0034] The MPEG-TS scheme is divided into a packet management data field and a payload as a basic format shared with a broadcasting scheme that broadcasts (distributes) compressed moving picture data, such as digital television broadcasting, broadcasting using a cable network such as the Internet, etc. etc. The payload includes data to be reproduced in a scrambled state. According to ARIB, PAT (Program Associate Table), PMT (Program Map Table), and SI (Service Information) are not scrambled. Also, various management information (SDT: Service Description Table, EIT: Event Information Table, BAT: Business Group (Bouquet) Contact Table) are generated using PMT and SI. Content to be reproduced includes MPEG video data, Dolby AC3 audio data, MPEG audio data, data broadcast data, and the like. Also, the content includes information such as PAT, PMT, SI, etc. ...

Abstract

The invention allows identification of a data recording unit that does not include any reference picture and a data recording unit that includes a reference picture. Specifying information (SOBU_MODE) indicating whether or not a target object (ESOB) includes the data unit (Non-Intra ESOBU) that does not include any reference picture or I-picture is provided in management information associated with that object.

Description

technical field [0001] The present invention relates to an information recording medium (or data structure), an information recording and reproducing method, and an information recording and reproducing apparatus suitable for recording and reproducing digital stream signals used in digital television broadcasting and the like, Background technique [0002] In recent years, television broadcasting has entered the era of digital broadcasting in which high-fidelity video programs (high-definition AV information programs) are the main broadcast content. Current BS digital broadcasting (and upcoming terrestrial digital broadcasting) employs MPEG2 transport stream (hereinafter abbreviated as MPEG-TS as needed). In the field of digital broadcasting using moving pictures, MPEG-TS is to be used as a standard format in the future. In the initial stage of such digital TV broadcasting, there is an increasing demand in the market for a stream converter that can directly record the conte...
