Method and apparatus of recording a high definition digital television broadcast signal

Abstract

The present invention relates to a method and apparatus of recording a directly-received digital television broadcast signal. This method demodulates a received high definition digital television broadcast signal, extracts transport stream belonging to a chosen channel among the demodulated data stream, analyzes data of the transport stream, extracts and creates data stream- and/or recording-related information, and writes the data stream- and/or recording-related information and the extracted transport stream to a recording medium in a format suitable to the extracted and created information. According to the present method and apparatus, it is possible to record a high definition digital television broadcast signal without any intermediary set top box to a high-density recording medium in the appropriate recording format as well as to conduct a trick play for recorded television broadcast signal smoothly with such recorded format and the data stream- and/or recording-related information.

       28 . A recording apparatus for preparing data for recording in a recording medium, the recording apparatus comprising: 
 means for preparing a transport stream from the data, the transport stream comprising at least one data pack, wherein the at least one data pack comprises at least one navigation information unit for navigating transport packets; and    means for recording in the navigation information unit program clock reference information and presentation time information associated with the transport packets.    
   
   
       29 . The recording apparatus of  claim 28 , further comprising means for managing presentation data according to a map based on the presentation time information.  
   
   
       30 . The recording apparatus of  claim 28 , wherein the at least one navigation information unit comprises no presentation data.  
   
   
       31 . The recording apparatus of  claim 28 , wherein the transport stream is in an MPEG format.  
   
   
       32 . The recording apparatus of  claim 28 , wherein each of the transport packet is 188 bytes.  
   
   
       33 . The recording apparatus of  claim 28 , wherein the transport packet comprises presentation data.  
   
   
       34 . The recording apparatus of  claim 28 , wherein the at least one data pack further comprises at least one transport packet.  
   
   
       35 . A recording medium for use with a playback apparatus, the recording medium comprising: 
 a first data area adapted for recording a transport stream comprising at least one data pack, wherein the at least one data pack comprises at least one navigation information unit for navigating transport packets; and    a second data area adapted for recording program clock reference information and presentation time information associated with the transport packets, wherein the program clock reference information and the presentation time information are part of the navigation information unit.    
   
   
       36 . The recording medium of  claim 35 , further comprising a third data area adapted for recording a map based on the presentation time information for managing presentation data.  
   
   
       37 . The recording medium of  claim 35 , wherein the at least one navigation information unit comprises no presentation data.  
   
   
       38 . The recording medium of  claim 35 , wherein the transport stream is in an MPEG format.  
   
   
       39 . The recording medium of  claim 35 , wherein each of the transport packet is 188 bytes.  
   
   
       40 . The recording medium of  claim 35 , wherein the transport packet comprises presentation data.
