1080p1080p is the shorthand identification for a set of HDTV high-definition video modes that are characterized by 1080 horizontal lines of vertical resolution and progressive scan, meaning unlike the 1080i display standard, the image is not interlaced.The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 1,920 pixels wide by 1,080 high. This resolution is similar to that of 2K digital cinema technology. The frame rate can be either implied by the context or specified after the letter p1, such as 1080p30, meaning 30 progressive frames per second.1080p, sometimes referred to in marketing materials as Full HD, typically refers to the capability to accept 1080p signal and display it with native resolution of at least 1080 lines, as well as the capability to upscale lower-resolution material to 1080p.The HD ready 1080p logo program by DIGITALEUROPE requires that certified TV sets support 1080p24, 1080p50, and 1080p60 formats, and feature a native resolution of at least 1920x1080 pixels, among other requirements.Production and broadcasting standards1080p HDTV1080pThe filmmaking industry has embraced 1080p24 (i.e. 1080p displayed at 24 frames per second) as a digital mastering format in both native 24p form and in 24PsF form. 1080p24 has become an established production standard for digital cinematography and there is plenty of equipment capable of capturing and processing 1080p24 signals. This may be the first universal video standard which transcends continental boundaries, an area previously reserved for 24-frame film.For live broadcast applications, a high-definition progressive scan format operating at 1080p at 50 or 60 frames per second is currently being evaluated as a future standard for moving picture acquisition. EBU has been endorsing 1080p50 as a future-proof production format because it improves resolution and requires no deinterlacing, allows broadcasting of standard 1080i25 and 720p50 signal alongside 1080p50 even in the current infrastructure, and is compatible with DCI distribution formats.1080p50/p60 production format will require a whole new range of studio equipment including cameras, storage and editing systems, and contribution links (such as Dual-link HD-SDI and 3G-SDI) as it has doubled the data rate of current 50 or 60 fields interlaced 1920 x 1080 from 1.485 Gbit/s to nominally 3 Gbit/s using uncompressed RGB encoding. Most current revisions of SMPTE 374M and EBU Tech 3299 require YCbCr color space and 4:2:2 chroma subsampling for transmitting 1080p50 (nominally 2.08 Gbit/s) and 1080p60 signal.Recent studies show that for digital broadcasts compressed with H.264/AVC, transmission bandwidth savings of interlaced video over fully progressive video are minimal even when using twice the frame rate, i.e. 1080p50 signal (50 progressive frames per second) actually produces the same bit rate as 1080i50 signal (25 interlaced frames or 50 sub-fields per second).ATSCIn the United States, the original ATSC standards for HDTV supported 1080p video, but only at the frame rates of 23.976, 24, 25, 29.97 and 30 frames per second (colloquially known as 1080p24z 1080p25, and 1080p30).In July 2008, the ATSC standards were amended to incorporate H.264/MPEG-4 AVC compression and 1080p at 50, 59.94, and 60 frames per second (1080p50 and 1080p60). Such frame rates require H.264/AVC High Profile Level 4.2, while standard HDTV frame rates only require Level 4.0. This update is not expected to result in widespread availability of 1080p60 programming, since most of the existing digital receivers in use would only be capable of decoding the older, less-efficient MPEG-2 codec, and operator bandwidth limitations do not allow for broadcasting two simultaneous streams on the same broadcast channel (e.g. both a 1080i MPEG-2 stream alongside a 1080p MPEG-4 stream).DVBIn Europe, 1080p25 signals have been supported by the DVB suite of broadcasting standards. The 1080p50 standard has been foreseen as a future-proof production format, and eventually a future broadcasting format. 1080p50 broadcasting should require the same bandwidth as 1080i50 signal and only 15-20% more than that of 720p50 signal due to increased compression efficiency though 1080p50 production requires more bandwidth and/or more efficient codecs such as JPEG 2000, high-bitrate MPEG-2, or H.264/AVC and HEVC.Since September 2009, ETSI and EBU, the maintainers of the DVB suite, added support for 1080p50 signal coded with MPEG-4 AVC High Profile Level 4.2 with Scalable Video Coding extensions or VC-1 Advanced Profile compression; DVB also supports 1080p encoded at ATSC frame rates of 23.976, 24, 29.97, 30, 59.94 and 60.EBU requires that legacy MPEG-4 AVC decoders should at least not crash in presence of SVC and/or 1080p50 (and higher resolution) packets. SVC enables forward compatibility with 1080p50 and 1080p60 broadcasting for older MPEG-4 AVC receivers, so they will only recognize baseli。
