DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcast receiving and recording method and a digital broadcast receiving and recording apparatus.

[0002]

2. Description of the Related Art In recent years, digital broadcasting has been actively standardized in various countries. In the United States, broadcasting systems referred to as Attempt Television (ATV) and in Europe are referred to as Digital Hierarchy Off-Road Casting (DVB), and digital broadcasting services based on these systems will be launched in a few years. In Japan, the Radio Industries Association (ARIB) is working on the standardization of digital broadcasting in Japan. The MPEG2 standard is the basis of these broadcasting systems, and the MPEG2 standard is 199
It became an international standard in four years.

[0003] First, the MPEG2 system standard, Generic Coatings Off Mocking Techniques Ant Associates Audio: Systems Recommendations H.222.0, I / O / I.C.
18-1 (GENERIC CODING OF MOVING PICTURES AND ASSOCI
ATED AUDIO: SYSTEMS Recommendation H.222.0, ISO / IE
The part related to program reception and program display will be outlined based on C 13818-1). As information necessary for selecting a program at the time of reception, MPEG2 uses Program Specific Information (PS).
It defines a table called I). There are the following three types of PSI tables defined by MPEG2.
These are all MPEG2 section type data.

PAT (Program Association Table): Program Association Table PMT (Program Map Table): Program Map Table CAT (Conditional Access Table): Conditional Access Table The data formats of PAT and PMT are shown in Tables 1 and 2, respectively. .

[0005]

[Table 1]

[0006]

[Table 2]

[0007] The PAT of a certain physical channel (transport stream) includes a program number (program_number) belonging to the physical channel and a packet ID indicating the PMT.
It is a table showing the relationship of (PMT_PID or program_map_PID). The PMT is composed of a program number and components of the digital stream (video data,
3 is a table showing a relationship between audio data and clock reference data). A detailed description of the parameters that make up the PAT and PMT is left to the MPEG2 system standard.

[0008] The European DVB standard also defines a table called service information (SI) for assisting program selection during reception. The DVB specifications for which SI is specified are: Digital Flowcasting Casting Systems for Telecommunications, Sound Anteater Services;
For Service Information (SI) Integral Video Float Casting Quark (DVB) Systems, HRTS 300 468, Zhun 1995
(Digital broadcasting systems for television, sou
nd and data service; Specification for Service Inf
ormation (SI) in Digital Video Broadcasting (DVB) sy
stems, prETS300 468, June 1995 "). In a digital receiver, even if only the PSI specified by MPEG2 is used,
Although the minimum program selection function can be realized, in DVB, S
By introducing I, it is intended to realize simpler program selection as compared with the case where only PSI is used. The following two types are the most influential SIs that support program selection.
DVB SI is MPEG2 like MPEG2 PSI.
This is section type data specified by.

SDT (Service Description Table): Program Description Table EIT (Event Information Table): Event Information Table The SDT describes a program (service) of a certain physical channel (transport stream). Table 3 shows the format of the SDT.

[0010]

[Table 3]

Next, a general mechanism of digital recording of a program using these tables will be described. Here, the recording of a single program will be described first.

It is assumed that a system for digital recording includes a receiving device and a digital video cassette recorder (digital VCR). FIG. 12 shows a conventional configuration. Digital broadcast receiving devices (receiving terminals) are usually
Digital set-top box (digital STB)
Alternatively, it is called an integrated receiver decoder (IRD). The digital receiving apparatus is usually provided with an interface for an external device called a high-speed interface, and is used for connecting a device such as a digital VCR. In FIG. 12, reference numeral 1 denotes a demodulation unit for digitally demodulating a received bit stream. Reference numeral 2 denotes a channel decoding unit which performs Viterbi decoding, deinterleaving, error correction, etc.
It reproduces the transport packet of EG2. Reference numeral 3 denotes a program designation unit for designating a program number of a program to be recorded. Reference numeral 4 denotes a PAT extraction / analysis unit for extracting and analyzing PAT. A PMT extraction / analysis unit 5 extracts and analyzes PMT. Reference numeral 6 denotes a recording packet extracting unit for extracting stream data such as video data and audio data to be recorded on the digital VCR. A PAT correction unit 7 rewrites the contents of the PAT according to the program to be recorded. 8
Is a high-speed interface for outputting stream data to be recorded from a receiving apparatus to a digital VCR. Reference numeral 9 denotes a digital VCR for recording a bit stream output from the receiving device.

The operation of the conventional example configured as described above will be described. First, the program specifying unit 3 specifies a program number to be recorded. The PAT extraction / analysis unit 4 extracts the PAT and outputs a PM corresponding to the program number (program_number) of the program to be recorded.
Extract T_PID (program_map_PID). The PMT extraction / analysis unit 5 stores the PAT extracted and analyzed by the PAT extraction / analysis unit 4.
A PMT packet having an MT_PID is extracted, and the PID of an elementary packet (video, audio, data) constituting a program to be recorded, that is, an elementary P
Take out the ID. The recording packet extraction unit 6 extracts an elementary packet having the elementary PID extracted by the PMT extraction / analysis unit 5. PAT correction unit 7
Invalidates the rest of the PAT extracted by the PAT extraction / analysis unit 4, leaving only the description relating to the designated program number, that is, the description indicating the correspondence between the designated program number and the PMT_PID.

The high-speed interface 8 includes a recording packet output from the recording packet extraction unit 6 and a P packet corresponding to the program number of the designated program output from the PMT extraction / analysis unit.
The PMT having the MT_PID and the rewritten PAT output from the PAT correction unit 7 are output to the digital VCR.

Here, it is assumed that three programs are simultaneously recorded in the configuration shown in FIG. The program numbers of the three programs to be recorded are program numbers a, b, and c (a, b, and c are natural numbers different from each other). These program numbers are selected by the viewer. Now, suppose the description about program_number = a is
In the section indicated by the section number section_number = p, the description about the program number = b is written as section_number = q
Is described in the section indicated by section_number = r (p, q, and r are mutually different values) in the section indicated by. That is, the description about the program number selected for recording is P
Suppose they belong to different sections of the AT. This is shown in FIG. Here, L PATs (L-1 is p, q,
(natural number not less than r). That is, last_section_number = L-1. When recording on a digital VCR, in order to indicate which program is to be recorded, only the description of the section corresponding to the program to be recorded, that is, the description corresponding to the program number and PMT_PID is extracted from the PAT, and the high-speed interface is executed. Must be recorded on the VCR via the Internet.

[0016]

In such a conventional example, when information of a program to be recorded is described in separate sections of the PAT as described above, the digital receiving apparatus operates in the corresponding section. Must be output to a digital VCR via a high-speed interface. The digital VCR needs to record all the sections (section p, section q, and section r) output from the digital receiver.

Considering the contents of the sections constituting the PAT of a certain transport stream, data other than section_number among the data constituting the section are almost common to each section except for the description in the loop. Recording the intersection of these sections is
It is inefficient from the viewpoint of the digital VCR recording band. Here, PAT has been described as an example, but the section loop is defined as service_id (synonym of program_number).
The recording of DVB SDT has the same problem as PAT in the sense that it rotates every time.

[0018]

In order to solve the above-mentioned problems, a method for constructing program information according to the present invention comprises the steps of, when recording a program, extracting a program association table from received data, and specifying a program to be recorded. And a step of newly configuring a program association table describing only information of one or a plurality of programs to be recorded based on the extracted program association table, and a newly configured program association table.
