AVCREC is a format for recording and playback of high definition video in BDAV (Blu-ray Audio/Visual) format [1] using conventional DVD recordable discs as recording media. Presently AVCREC is tightly integrated with ISDB broadcast standard and is not marketed outside Japan.
AVCREC was defined in 2007 as the means of recording of high definition ISDB broadcasts on existing DVD recordable discs. Using widespread DVDs offers consumers an immediate economical option for HD content storage on DVDs. [2]
AVCREC is a more economical and simple version of Blu-ray video adapted for set-top device video recording, just like AVCHD is an economical version of Blu-ray video adapted to video cameras. [3]
An AVCREC recorder can use either MPEG4/AVC or MPEG-2 video encoding to record the video. In the so-called DR mode a recorder does not re-compress the incoming signal, fully preserving the original quality of a broadcast program. Some devices offer "long play" modes with compression up to 5x higher than original signal, with corresponding loss of quality. MPEG4/AVC is usually used for "long play" modes as a more effective compression scheme compared to MPEG-2. [4]
Recorded AVCREC video can be played back on a recording device, on a compatible Blu-ray player or on a computer.
Digital video is an electronic representation of moving visual images (video) in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession.
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems which, in turn, were replaced by flat panel displays of several types.
Video CD is a home video format and the first format for distributing films on standard 120 mm (4.7 in) optical discs. The format was widely adopted in Southeast Asia, Central Asia and the Middle East, superseding the VHS and Betamax systems in the regions until DVD-Video finally became affordable in the first decade of the 21st century.
WinDVD is a commercial video player and music player software for Microsoft Windows. It enables the viewing of DVD-Video movies on the user's PC. DVD-Video backups stored on hard disk can also be played. The player can also be used to play videos and audio/music files in other formats encoded with different codecs, for instance DivX, Xvid, Windows Media Video video and MP3 and AAC audio. Newer versions also support full Blu-ray Disc and HD DVD playback with menus, with CPRM DRM support.
A camcorder is a self-contained portable electronic device with video and recording as its primary function. It is typically equipped with an articulating screen mounted on the left side, a belt to facilitate holding on the right side, hot-swappable battery facing towards the user, hot-swappable recording media, and an internally contained quiet optical zoom lens.
HDV is a format for recording of high-definition video on DV cassette tape. The format was originally developed by JVC and supported by Sony, Canon, and Sharp. The four companies formed the HDV Consortium in September 2003.
SMPTE 421, informally known as VC-1, is a video coding format. Most of it was initially developed as Microsoft's proprietary video format Windows Media Video 9 in 2003. With some enhancements including the development of a new Advanced Profile, it was officially approved as a SMPTE standard on April 3, 2006. It was primarily marketed as a lower-complexity competitor to the H.264/MPEG-4 AVC standard. After its development, several companies other than Microsoft asserted that they held patents that applied to the technology, including Panasonic, LG Electronics and Samsung Electronics.
A DVD recorder is an optical disc recorder that uses optical disc recording technologies to digitally record analog or digital signals onto blank writable DVD media. Such devices are available as either installable drives for computers or as standalone components for use in television studios or home theater systems.
MPEG transport stream or simply transport stream (TS) is a standard digital container format for transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data. It is used in broadcast systems such as DVB, ATSC and IPTV.
XDCAM is a series of products for digital recording using random access solid-state memory media, introduced by Sony in 2003. Four different product lines – the XDCAM SD, XDCAM HD, XDCAM EX and XDCAM HD422 – differ in types of encoder used, frame size, container type and in recording media.
The Nextcom R5000-HD is a popular Windows-based system for digitally capturing HD (high-definition) and SD (standard-definition) TV content from satellite TV and cable TV sources. A modification is required to the set-top box, giving it a USB 2.0 output that is connected to a PC. The digital video recorder (DVR) and companion personal video recorder (PVR) software runs on any Windows 2000, Windows XP, Windows 7 and Windows 10 system and can record just about any content to hard disk or D-VHS tape. Programming can be encoded in MPEG-2, or MPEG-4 type AVC/H.264 formats. MPEG transport streams compliant with the ISO 13818-1 specification are created.
AVCHD is a file-based format for the digital recording and playback of high-definition video. It is H.264 and Dolby AC-3 packaged into the MPEG transport stream, with a set of constraints designed around the camcorders.
The first attempt at producing pre-recorded HDTV media was a scarce Japanese analog MUSE-encoded laser disc which is no longer produced.
This article compares the technical specifications of multiple high-definition formats, including HD DVD and Blu-ray Disc; two mutually incompatible, high-definition optical disc formats that, beginning in 2006, attempted to improve upon and eventually replace the DVD standard. The two formats remained in a format war until February 19, 2008, when Toshiba, HD DVD's creator, announced plans to cease development, manufacturing and marketing of HD DVD players and recorders.
The Blu-ray Disc (BD), often known simply as Blu-ray, is a digital optical disc storage format. It is designed to supersede the DVD format, and capable of storing several hours of high-definition video. The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Wii U, Xbox One, and Xbox Series X. The name "Blu-ray" refers to the blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.
The following is a list of H.264/MPEG-4 AVC products and implementations.
HD DVD is a discontinued high-density optical disc format for storing data and playback of high-definition video. Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format.
.m2ts is a filename extension used for the Blu-ray disc Audio-Video (BDAV) MPEG-2 Transport Stream (M2TS) container file format. It is used for multiplexing audio, video and other streams. It is based on the MPEG-2 transport stream container. This container format is commonly used for high definition video on Blu-ray Disc and AVCHD.
DVD-Video is a consumer video format used to store digital video on DVD discs. DVD-Video was the dominant consumer home video format in Asia, North America, Europe, and Australia in the 2000s until it was supplanted by the high-definition Blu-ray Disc. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder. Commercial DVD movies are encoded using a combination MPEG-2 compressed video and audio of varying formats. Typically, the data rate for DVD movies ranges from 3 to 9.5 Mbit/s, and the bit rate is usually adaptive. DVD-Video was first available in Japan on November 1, 1996, followed by a release on March 24, 1997 in the United States—to line up with the 69th Academy Awards that same day.
SD Blu-ray disc is a Blu-ray disc on which the main feature is standard-definition video instead of the high-definition video found on typical Blu-ray discs.
