DSTV: Ironic

Isn’t it ironic, that I posted the article DSTV – High-definition – WTF? almost 12 months ago?

If you go back to the original article you will still cringe. There is still only one channel, the HDPVR costs now R 1000,00 more (retailing at R 3,499.00) and still offers an inferior viewing experience (due to the many bugs).

There is still no proper solution for the now discontinued SDPVR which at least had dual-view capabilities. XtraView is cumbersome and you will land up recabling most of your house to get it going. There is also uncertainty about new players entering the South African market and with Seacom’s “broadband revolution” other means of high-def experiences such as Netflix might be a more feasible option.

DSTV – High-definition – WTF?

DStv operator MultiChoice announced at a press-release last week, that they will (finally) launch O-N-E high-definition channel on August 1. The channel, which will be available in a resolution of 720p, will be used to broadcast the Olympic Games from August 8 (apparently not life, but re-broadcasts), and from August 24 it will carry a new entertainment channel called M-Net HD.

The device, which includes a 500GB hard drive, costs the same as the standard-definition (SD) PVR model — R2 499 — and is capable of storing 150 hours of SD content and 50 hours of HD material.

Come on Multichoice — ONE CHANNEL???? Most of the HD-content broadcast on the marvelous new HD-channel will be anyway multi-cast on standard definition: Season 6 of CSI Miami (Tuesdays at 8.30pm), Season 4 of CSI New York (Thursdays at 9.30pm, and Season 1 of Gossip Girl. Other shows include season 3 of My Name is Earl, season 1 of Samantha Who, season 4 of Lost and season 1 of Reaper.

But wait – there is more – a whole bucket of high-def movies (all of which you should have on Blu-ray already): Die Hard 4, Zodiac, Fantastic Four: Rise of the Silver Surfer, Spiderman, Oceans Thirteen and Shrek the Third.

The new HD-PVR is a step backwards though. While the current SD-PVR features dual-view (you can hook up two TVs, record one programme but watch two different channels in parallel), the “new” HD-PVR will only support watch one and record two – WTF? DSTV is broadcasting so many repeats anyway, so it is pretty pointless two record two programmes simultaneously anyway.

But there is XtraView which eventually will allow you to pair your existing decoder/PVR with your HD-PVR and will then give you view-three/record-three (if you pair the HD-PVR with a SD-PVR).

The device would have been appealing if even SD content looked better via HDMI (if you are running an LCD bigger than 46″ you will find out that most programming appears washed out or grainy). But to just watch one channel with re-broadcasts in high-definition defeats the purpose of forking of R 2,500.00.

I am certainly not going to get a HD-PVR, as Multichoice will only launch XtraView “sometime in October”. Multichoice was supposed to provide a firmware update to stabilise the PVR’s by last year October and is only now managing (10 months later) to deliver it. So who believes that XtraView will be on time. Not to mention that you will either have to fit a splitter/multiplexer and in the worst cast re-cable/re-install (if you do not have a twin-LNB).

Color calibrating your HDTV

If you own a PS3, chances are that you also own Casino Royale (either because you got the movie from SterKinekor for free like I, or you bought it). Like many Sony titles, this Blu-ray title includes test-patterns – you just type in “7669″ and OK on the main-screen and will then be able to skip through a number of test-patterns. (BTW: 7669=SONY).

Most high-definition TVs sold in shops have high-contrast levels and vivid-color settings, which are not natural. Ever since I got the Sony Bravia KLV-46X300A, I wanted to achieve D65 picture settings – in essence getting a neutral grayscale that puts the “color of white” just where it belongs, at the chromaticity known as D65. D65 is sometimes (slightly erroneously) identified with the D6500 or 6500K “color temperature,” but whatever it’s called, the accuracy of a TV’s white point is important. All colors are in effect computed from four anchor points: the white point and the three primaries. So if the white point is wrong, all the computations are wrong.

The ultimate goal is to adjust the three primary colors to produce whites and grays as close to perfect as can be achieved at every level along the available brightness scale from near-black dark grays on up to near-white light grays, and finally to so-called “reference white.”

Take a look at a screenshot from Die Hard 4.0 (blu-ray) – you will notice D65 settings in the 1st, 3rd and 5th block (2nd/4th are the factory default settings) of the image below:

If you’re not used to D65 images, you may find the picture too yellow / red at first glance. This is because most of us are used to the 9300k colour temperature on most computer monitors, and have been conditioned to think that these whites are the real “white” (when they in fact look brighter due to their cooler colour temp). All I can say is that D65 is the standard adopted by movie makers and broadcast studios, which means that you should calibrate your television to D65 if you wish to see the colours in a movie reproduced as the director intended.

What I suggest is to persevere with the above settings for 3 days to 1 week to get used to D65, and then revert to the out-of-the-box settings, at which point hopefully you’ll realise how artificial the colours were before calibration.

For the PS3 I turned off all noise-reductions and corrections and enhances (such as MPEG, edge, detail). For standard definition TV (DSTV) I left all D65 customisations the same but turned on the DRC enhancements (switched to DRC Mode 1, changed DRC palette reality to 20 and DRC palette clarity to 100)

Big Buck Bunny premiere

I stumbled across Big Buck Bunny – a 10 minute video rendered completely on Linux Blender.

Big Buck Bunny is a comedy about a well-tempered rabbit “Big Buck”, who finds his day spoiled by the rude actions of the forest bullies, three rodents. In the typical 1950ies cartoon tradition Big Buck then prepares for the rodents a comical revenge.

It took 6 months to produce the clip on open-source technology and the 200MB 480p clip looks amazing:

If you do not mind watching a couple of cute, furry animals being killed, watch below or download the high-definition version from the above website.

Sofar there are over 400,000 downloads and the clip has been watched over 1,000,000 times. The downloads alone amounted to 29TB of traffic (IN ONE WEEK).
