QUOTE
With the new RTD1283 program listing of the major forums for Sigma Designs and the two chip manufacturers Realtek contrast more intense discussion, of course, there is also no lack of manufacturers representatives Huyou, misleading consumer choices consumers make mistakes. Well, today we have to broke the news about the two mainstream chips, "hidden rules."

RTD1073 and SMP8635 sound quality comparison
Sound quality, SMP8635 supports DTS-HD source output, sound quality is also ahead of other decoding RTD1073, a next-generation power amplifier cares about sound quality would no doubt choose SMP8635, or no less demanding on the next-generation audio amplifier can choose to RTD1073. However, Realtek chip, the emergence of newly published RTD1283 changed the status quo, it can well supported next-generation audio, but now on the market use RTD1283 chip players still less than normal.

RTD1073 and SMP8635-quality comparison
Quality aspects, RTD1073 Although the program's products have also played the banner of 1080p, but the actual number of low-end products only go to 720p. If you need to use super-high-definition projection watch, then 1080p will find RTD1073's a lot less than the SMP8635 of 1080p. So SMP8635 is more practical for high-quality requirements, and recommended the use of home theater program.

RTD1073 and SMP8635 Network Comparison
In the network support, although the RTD1073 and SMP8635 support network function, support BT download. However, the reasons are basically SMP8635 software and hardware products in the domestic BT download difficult to achieve. RTD1073 relatively simple to set up the software, the hardware also has good support, BT download can be a very good implementation. But the Realtek network advantages not only this, the new RTD1283 chip also supports the popular WiFi networks, including direct support for large-scale video website YouTube in support of the mainstream media, RSS capabilities. That a rich network applications will also become an important reason why users choose Realtek.
RTD1073 and SMP8635 File Format Comparison

For the file format support, RTD1073 have an absolute advantage, SMP8635 is no advantage at all, because RTD1073 supports RMVB, RM, if you have to look at RMVB, then definitely choose RTD1073 program. After all, some of the many resources online to download or use of RMVB format, high-definition player, the necessary functions less.
RTD1073 and SMP8635DTS decoding contrast

In the DTS decoder area, RTD1073 chip products basically support DTS software decoding. The SMP8635 also features soft solution although the DTS capabilities, but not with SMP8635 software products that support DTS decoding, we pay special attention to the time of purchase, different brands have different models, if the product was not bought SMP8635 software solution DTS capabilities, but also want to buy their own decoders, it uneconomical. RTD1073 and the use of technology RTD1283 Comparison

Although the division RTD1073 and RTD1283 out of the same door, but they are prepared for different purposes. RTD1073 targeted at players, but RTD1283 located in the hard disk-like video recorders, playback, if only from the point of view, no distinction between the two. From the view of the chip manufacturing process, RTD1283 using more advanced technology, RTD1283 is a BGA package, rather than RTD1073.
RTD1073 and RTD1283 thermal stability of the contrast


Realtek RTD1073 program the biggest bottleneck is the heat, high heat to bring the stability and reliability also will be reduced; Another problem is the firmware, for now, Taiwan's Realtek has not done right, as the United States, SIGMA Customers open source, such RTD1073 inside BUG, also need to Realtek themselves gradually solved.

From the comparison, it seems that the output of Realtek is brighter and crisper and to my eye it is better, the Sigma tends to give softer picture...

my observation is opposite, i..e sigma is sharper (realtek softer).. so does owners who own both units and spend considerable time on both units..


Added on December 19, 2009, 3:44 pmas your link show, which is sharper and which is softer..

Even though this result shows the Sigma is shaper but overall I feel the realtek graphic is much saturated giving vivid colors.

Its almost the same except that the Live got network capability so can stream video from your PC's HDD and got youtube, internet radio and flickr built in.

Live also have cpu twice the speed so it can play any mkv you throw at it and can even play the high reframe rates mkv.

Even the WDTV (non-live) has 2 versions. The very first one does not have DTS downmix and does not support DeepColour because it is HDMI1.2. The second version is HDMI1.3, has DTS downmix, and supprts deepcolour. The latest firmware for this second version has already been released and can be found on WDC homepage.

Has this been verified with a meter? If not, and someone is willing to loan me one to generate the charts, I would be happy to show the results. I can get hold of the Live for comparison, just need one with the Realtek chip.

I just checked out the comparison, which in my opinion is not the correct way. The author is comparing apples to oranges. These shd be compared post calibration. From what I read, he is comparing out of the box. Each chipset will be different.

Also, most definately, the Realtek has an in built sharpening tool. It is clear in the test pattern. The only way u can see the artefacts like jagged lines is when u turn up sharpness too much.

As such, to the untrained eye, on normal pictures the Realtek will appear sharper, albeit, wrong.

Based on just images, the Sigma seems to be doing a more accurate greyscale, whereas the Realtek is way too cool whites.

Err..not exactly the right thread but while we're still "hoping" for HD audio, anyone here knows where I can get this (HDX BD-1)?

http://www.hdx1080.com/

which looks to be the ultimate player. Sometimes, u just wanna pay a premium price and get a unit with the "least" amount of problems.
