Benefits of technology
Enables the direct recording of HDTV signals to high-density media without intermediary devices, supporting trick play functionality and adapting recording formats to the received data streams, thus overcoming bit rate limitations and enhancing storage capacity for HDTV content.
Problems solved by technology
As a result, a streamer observing the provisional standard can not record high definition moving pictures broadcasted from a broadcasting station to a disk recording medium normally.

Embodiment Construction
[0024] In order that the invention may be fully understood, a preferred embodiment thereof will now be described with reference to the accompanying drawings.
[0025]FIG. 2 shows an example of home appliance network. In network of FIG. 2, a high-density DVD recorder 400 records a received HDTV broadcast signal to a writable high-density DVD or transmits the received HDTV signal to a digital television 500 being able to accept data stream of HDTV signal or a STB 600 which is connected through IEEE 1394 standard. The data stream of HDTV signal may be received from a digital broadcasting station or a high definition digital video camera connected through IEEE 1394.
[0026] The high-density DVD recorder 400 may have an MPEG decoder decoding digital data stream to analog video and audio signal which is for a high definition monitor 700 not equipping with a MPEG decoder.
[0027] The internal components of the high-density DVD recorder 400 and their operations are explained in detail hereinaft...

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.
Description
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a method and apparatus of recording a high definition digital television (HDTV) broadcast signal to a high-density disk storage medium such as a HD-DVD (High-Density Digital Versatile Disk). [0003] 2. Description of the Related Art [0004] A conventional analog television signal is transmitted through air or cable after AM or FM modulation. [0005] In these days, digital technologies related with video compression and modulation / demodulation has been remarkably advanced, so that digital television broadcast, whose standard is locally under discussion, is being introduced in air broadcasting system. The digital television broadcast system has adopted MPEG standard as video and audio compression method. [0006] The digital broadcast system can provide higher quality than analog system, transmit several different programs through an allocated single band, and make it possible to fully use ...
