As illustrated in Figure 1, in the method according to the invention there are used six distinct steps, to wit:
  • Video pre-production 3. Interactive data pre-production;
  • Step 1 Audio pre-production
  • the audio intended to be used originating from various sources, must be received by the computer, by means of a standard digital sound card of 24 bits or above, and must be stored in a file.
  • the digitized audio file is processed by computer programs for audio treatment, that will correct problems related to equalization, noise and other faults.
  • the audio matrix in a file which will be used in subsequent steps.
  • the audio matrix in a file undergoes two distinct types of treatment, one intended for use of the audio to render the same compatible with the CD-DA (Compact Disc Digital Audio) standard, as shown in step 1.1 below, and another that will be used to render the same compatible with its respective content in digital video as shown in step 1.2 below.
  • CD-DA Compact Disc Digital Audio
  • Step 1.1 Compatibilization with the CD-DA standard
  • the audio matrix in a file is processed by an audio treatment program, where its audio frequency is set to 44.100 Hz, its transfer rate (bit rate) is set to 128 Kb/s (kilobits per second) and its resolution is set to 16 bits.
  • Step 1.2 Compatibilization for multiplexing with digital video
  • the audio matrix in a file is processed by an audio treatment program, where its channel format is defined in "joint stereo", its audio frequency is set to 44.100 Hz, its transfer rate (bit rate) is set to 112 Kb/s (kilobits per second) and its resolution is set to 16 bits.
  • WAV format Windows Audio File Format
  • Step 2 - Video pre-production ( Figure 3)
  • the video should be captured into the computer by means of a professional vide capture board and should be recorded in a MPEG standard digital video file.
  • step 1.2 the multiplexing (joining) of the MPEG digital video file with the digital audio file obtained in step 1.2, which will generate the file known as System MPEG, which will have its GOP structure altered for optimization of its compression rate, allowing to record, in a 74-minute CD (Compact Disc), up to 128 minutes of video, which exceeds, for example, the storage capacities provided in standards such as the VCD (Video Compact Disc) and SVCD (Super Video Compact Disc).
  • VCD Video Compact Disc
  • SVCD Super Video Compact Disc
  • Step 2.1 Alteration of the GOP (Group of Pictures) structure of the System MPEG file
  • System MPEG file should have the following initial characteristics: System MPEG Version 1.0 (MPEG-1);
  • Video size 352 X 240 pixels (video resolution measurement unit); Screen proportion standard: 4:3 525 lines NTSC (National Television System Committee);
  • Video speed 29.97 frames per second to obtain greater quality, or 23.976 frames per second to obtain greater compression;
  • Variable bit transfer rate minimum of 300 Kb/s and maximum of 1,150 Kb/s.
  • I-Picture Intra coded frames
  • P-Picture Predicted frames
  • B-Pictures Bidirectional frames
  • Video, data and audio compatibilization step makes possible the creation of the ISO 9660 image in mixed mode 2, allowing the various playback devices in the market (CD Player, DVD/VCD Player, DVD-ROM, D-ROM etc.) to identify the information that is compatible with their playback system and to execute the same.
  • the first track will be mandatorily composed by the information related to the interactive data pre-production step (interactive data), following the guidelines defined in the ISO 9660 standard; from the second track onwards, there will be recorded the information relative to the desired video pre-production step, where each digital video file comprises an individual track.
  • These tracks will be recorded using the RAW data standard (data organized in sectors of 2,352 bits); upon having recorded the video tracks, there will be recorded the information related to the compatibilization with the CD-DA standard of the audio pre-production step, where each digital audio file comprises an individual track, following the specifications defined for the Red Book (audio CD) format.
  • Step 5 Pre-mastering in hybrid format of the ISO 9660 image
  • the purpose of this step is to perform the "burning recording" of the ISO 9660 image generated in the video, data and audio compatibilization step, using the following specifications:
  • Type of medium CD-R 74 minutes, matte silver.
  • Step 6 Mastering The purpose of this step consists in performing the recording by "pressing" of the CD, which will allow the same to be read in CD Player and DVD/VCD Player apparatuses.
  • This step is performed by companies specializing in this operation, which will reproduce the desired medium in a scale fit for commercialization.
