Problems solved by technology

[0008]However, converting a stream multiplexed into MPEG_TS to MPEG_PS involves recalculation of decoder buffer management, TS2PS conversion is time consuming and often involves Re-encoding of elementary streams, resulting in reduced picture and sound quality

[0283] The basic recording and playback operations of the data recording and reproducing apparatus according to the present invention have been roughly described above, and therefore, the following reference Figure 20 Only the basic operation of recording analog line input is described in detail. The object type recorded in this example is TS1_VOB.

[0284] An analog line-in recording request from a user is transmitted from the user interface 222 to the system controller 212 . Then, the system controller 212 sends a receive command to the line input unit 223 and a data encoding command to the encoder 214 .

[0285] The MPEG transport stream from encoder 214 is sent to track buffer 220 .

[0286] To generate the VOB information (TS1_VOBI) of the encoded MPEG transport stream (TS1_VOB), the encoder 214 first sets time stamp information as a presentation start time (TS1_VOB_V_S_PTM), and sends it to the system controller 212 . This start time value is set as Start_PTM of the ...

[0368] Another embodiment of the present invention is described below. First, the encoder of the data recording apparatus according to the present invention will be described by focusing on the encoding process of receiving and self-encoding AV input into an MPEG transport stream.

[0369] Figure 33 The configuration of the encoder in the data recording device according to the present invention is shown. As shown, encoder 214 includes elementary stream encoders 230 a , 230 b , and 230 c , and system encoder 232 . Encoder 214 receives a control signal from system controller 212, and then performs an encoding process through elementary stream encoders 230a, 230b, and 230c, or system encoder 232, while switching between elementary encoding and system encoding. Each elementary stream encoder 230a, 230b, and 230c receives video, audio, and VBI (vertical blanking interval) signals for encoding.

[0370] Video encoder 230a receives control signals from system controlle...

Abstract

The present invention provides an apparatus and a method for recording on the information recording medium. Flag information indicating that data has been recorded by a limit format capable of converting a first stream (such as an MPEG transport stream) to a second stream (such as an MPEG program stream) is recorded in management information (VOBI). By referencing this management information, it is possible to easily recognize whether record data has been recorded by the limit format or not without analyzing the data recorded on the information recording medium.

Description

[0001] Case Description [0002] This application is a divisional application of a Chinese patent application with an application date of July 23, 2002, an application number of 02814868.1, and a title of "A device and method for recording information to an information recording medium". technical field [0003] The present invention relates to a readable and writable data recording medium, and more particularly to data recording of moving picture (video) data, still picture data, audio data, and other types of multimedia data in data broadcasting and various other formats recording medium. The invention also relates to apparatuses and methods for recording data to the data recording medium, and for playing the data from the data recording medium. Background technique [0004] Rewritable optical discs have had a maximum storage capacity of about 650MB, but the introduction of DVD-RAM discs, a phase change type of storage medium, has pushed this constraint to several gigabyt...
