HDCAM, introduced in 1997, is a high-definition video digital recording videocassette version of digital Betacam, using an 8-bit discrete cosine transform (DCT) compressed 3:1:1 recording, in 1080i-compatible down-sampled resolution of 1440×1080, and adding 24p and 23.976 progressive segmented frame (PsF) modes to later models. The HDCAM codec uses rectangular pixels and as such the recorded 1440×1080 content is upsampled to 1920×1080 on playback. The recorded video bit rate is 144 Mbit/s. Audio is also similar, with four channels of AES3 20-bit, 48 kHz digital audio.
Like Betacam, HDCAM tapes are produced in small and large cassette sizes; the small cassette uses the same form factor as the original Betamax.
The main competitor to HDCAM is the DVCPRO HD format offered by Panasonic. It uses a similar compression scheme and bit rates ranging from 40 Mbit/s to 100 Mbit/s depending on frame rate.
HDCAM is standardized as SMPTE 367M, also known as SMPTE D-11.
SMPTE 367M, also known as SMPTE D-11, is the SMPTE standard for HDCAM. The standard specifies compression of high-definition digital video. D11 source picture rates can be 24, 24/1.001, 25 or 30/1.001 frames per second progressive scan, or 50 or 60/1.001 fields per second interlaced; compression yields output bit rates ranging from 112 to 140 Mbit/s. Each D11 source frame is composed of a luminance channel at 1920 x 1080 pixels and a chrominance channel at 960 x 1080 pixels. During compression, each frame's luminance channel is subsampled at 1440 x 1080, while the chrominance channel is subsampled at 480 x 1080.
Un-spoken words, un-kept promises
This is what a man should do in his life
Un-broken alliance, still on and on and on
We just don't know, time after time
Lost in this world
I'll find a reason why
To live in perfect harmony with you my shining star, side by side
Together we will fight
Together we'll survive
To millions battle just to testify our love
Who will be the next today
To forget the lesson learned in wasted years long long time ago
It's been a shame, it's been so fake
To be prisoners of ourself
We just don't know, time after time
Lost in this world
Story will tell, who will be wise
And who will survive
Caught in this world
Caught through this lies
