HDCAM-SR Format Recording
Creating Visually Lossless Images:
The MPEG-4 SStP Simple Studio Profile
Yet another industry first from Sony is an integrated video
encoding/decoding chipset that conforms to MPEG-4 SStP
Simple Studio Profile (ISO/IEC 14496-2). The Studio Profile was
created to specifically address the requirements of high-resolution
image-production applications. It is free from GOP (Group Of
Pictures) structures, and is scalable in its pixel count (SDTV, HDTV,
film-resolution data), bit depth (10- or 12-bit), and color resolution
(component or RGB). In order to achieve maximum compression
efficiency, the HDCAM-SR format uses intra-frame compression for
progressive images and intra-field compression for interlaced
images. Special attention has been paid to multi-generation
dubbing performance and, in common with industry-standard
Digital BETACAM VTRs, the SRW-5800/5500/5000 is capable of
consistent dubbing without using a separate interface for a
native stream. This is only possible thanks to the high
performance of the MPEG-4 SStP Simple Studio Profile, which offers
reproduction of visually lossless images.

1080 Recording and Playback
The SRW-5800/5500/5000/5100*
1
can record and play back full
HD images with exceptionally high picture quality using 1080 x
1920 active pixels, as specified by the ITU Common Image Format
(CIF). The entire range of both interlaced and progressive frame
rates is available, from 50i/60i and 24p/25p through to
50p/60p*
2
, covering high-end HDTV production applications, and
commercial and cinema productions. The SRW-5800/5500/5000/
5100*
1
can also record and play back top-quality 4:2:2 Y/Cb/Cr
component or full-bandwidth 4:4:4 (RGB) 10-bit recordings, both
with very mild compression. The SRW-5800/5500/5000/5100*
1
offers up to 12 channels of 24-bit audio at 48 kHz or 96 kHz*
3
, to
meet the needs of the most demanding audio recording tasks in
digital-content mastering. Each channel is independently
editable. HDCAM-SR VTRs are the optimal VTR for any movie-
making task - from acquisition and editing to telecine transfers
and digital mastering.
*1: The SRW-5100 is playback only.
*2: The 1080/50p or 60p mode is available on the SRW-5800/5100.
*3: With the SRW-5800/5100 only. 96 kHz audio sampling is up to six channels for
440 Mbps mode and up to 12 channels for 880 Mbps mode.
4:2:2/1080/60p and 50p Mode
The 4:2:2/1080/60p and 50p recording mode is highly
compatible with computer graphics, games, and other
progressive-based programs such as demonstration reels for flat-
panel displays. Events with a lot of fast-moving images, such as a
sports match, are well suited to the 4:2:2/1080/60p and 50p
mode. Also, when converting material originated in 1080/60p or
50p format to 720p format, this mode offers exceptional picture
performance due to the original high resolution of 1920 x 1080.
Another benefit of using the 4:2:2/1080/60p and 50p recording
mode is that it enables image creation with extremely high-
quality slow-motion effects when a tape recorded in these modes
is played back in 23.98p, 24p, 25p, or 30p mode.
3D Stereoscopic (Dual Stream) Mode
Dual Stream mode provides the SRW-5800 with the capability to
record the images of two cameras simultaneously with in-sync
audio and time code in both 422 and 444 mode, making it
possible for users to shoot two different scenes simultaneously or
achieve 3D stereo shooting. The materials shot in Dual Stream
mode with the SRW-1 HD Portable Digital Video Recorder can be
played back with the SRW-5800/5100. The SRW-5500/5000 can
play back either channel A or channel B of the Dual Stream
recording.
