While 1080p is sometimes referred to in marketing materials as "True High-Definition" or "Full High-Definition", what constitutes ) shoot their digital films in this high definition mode to be shown in theaters equipped with 1080p digital projectors. BROADCASTING STANDARDS Due to Bandwidth limitations of broadcast frequencies, the ATSC and DVB have standardized only the frame rates of 24, 25, and 30 frames per second (1080p24, '''1080p25''', '''1080p30'''). 1080p30 is currently the most bandwidth-intensive video mode supported. If the standard MPEG-2 compression is used, versions with higher frame rate such as '''1080p50''' and '''1080p60''' could only be sent over higher-bandwidth channels; to send these over normal-bandwidth channels, a more modern Codec such as the H.264/MPEG-4 AVC codec must be used. Higher frame rates such as 1080p50 and 1080p60 are currently for private or internal use only, and are not part of the broadcasting standard. The ATSC is considering amending its standard to allow the incorporation of the newer codecs for optional usage like the DVB Consortium already has done with DVB-S2 . However, this is not expected to result in widespread consumer availability of broadcast 1080p programming, since most of the existing digital television sets, or external digital receivers would still only be capable of decoding the older, less-efficient MPEG-2 codec, while the bandwidth limitations do not allow for broadcasting two simultaneous streams (i.e. both a 1080i or 720p MPEG-2 stream alongside a 1080p MPEG-4 stream) on the same broadcast channel. PRODUCTION STANDARDS A new high-definition progressive scan format for picture creation is currently being developed to operate at 1080p at 50 or 60 frames per second. This will require a whole new range of studio equipment including cameras, storage, edit and contribution links as it has double the data rate of current 50 or 60 field interlace 1920 × 1080 from 1.485 Gb/s to nominally 3 Gb/s. It is unable to be broadcast in a compressed transmission to current MPEG-2 based HD receivers. This format will improve final pictures because of the benefits of "over-sampling" and removal of interlace artifacts. AVAILABILITY Broadcasts Even though various television networks in the world broadcast HDTV programming in 1080i and 720p , no 1080p broadcasting actually exists at this time. Material that has been digitized from a 35-mm film source is basically 1080p24 though, fit into 1080i50 or i60 (''progressive with segmented frames''). Consumer televisions There is a growing selection of consumer released ''Qualia 004'' , a 1080p-resolution front-projector (it could not accept 1080p signals), while Mitsubishi released a 1080p rear-projection TV; both were based on LCoS technology and had limited availability. Several televisions in 2005 offered 1080p, including sets from HP , Mitsubishi, Samsung and Sony. The 2006 CES introduced 1080p displays from most manufacturers, available in various display technologies. Computer monitors monitors use 1080p as a Native Mode . Storage format 1080p-encoded titles have been released on . 1080p and near-1080p content has also been released on regular DVD-ROM disks using WMV HD compression. These titles cannot be played in normal DVD players and can only be viewed on a Windows -based computer with a 3.0 GHz Intel Pentium IV equivalent or better CPU , among other hardware requirements.Microsoft.
