Blu-Ray Vs. HD-DVD - Contagem de Espingardas

Permite leitura bitstream dos audios dito normais, Dolby Digital e DTS. O True HD e DTS HD MA não permite, devido a uma limitação de hardware qualquer na saída HDMI, nunca irá permitir.

Entrando na conversa ...

A PS3 descodifica Dolbi TrueHD e passa por HDMI PCM Linear.
O DTS HD MA não descodifica mas extrai o DTS core @1.5 mbps, mas que não é lossless, mas é superior ao DTS normal dos DVDs.

Em alguns foruns falam que nos próximos firmwares (2.30 ou 2.40) a PS3 já vai ser capaz de descodificar DTS HD MA.

Desta maneira para estes audios HD, com a PS3, basta possuir um AV Amp. com entradas HDMI capazes de tratar PCM Linear de 5.1 ou 7.1 canais.

Pois, mas continua a não permitir a leitura por Bitstream e praticamente sempre a performance é bem melhor quando deixamos o receiver fazer esta função.
Neste momento só os receiver de baixa gama é que ainda não descodificam os novos audios e dentro de um ou dois anos, até estes. Para quem quer comprar um receiver de gama média o alta, é PS3 não chega.
Seria bom que a Sony lançasse um modelo revisto, que tivesse uma saída HDMI que permitisse a leitura dos audios por bitstreaming. O upgrade seria insignificante para a maioria, mas útil para uns poucos.

A sony está a lançar novos amps (linha de 2008) nos States:

STR-DG520 5.1 ($199), STR-DG720 7.1 ($299), STR-DG820 7.1 ($399) e STR-DG920 7.1 ($599)...

Todos 1080/24p path-thougth

STR-DG720 tem suporte para PCM Linear de 8 canais
STR-DG820 e STR-DG920 já suportam descodificação Dolby True HD e DTS HD MA

Outras caratecteriscas no site da sony US...

Acho que estão a um preço interessante se forem lançados na Europa com preço semelhante, principalmente o STR-DG820.

Opah, tendo os novos formatos tanta qualidade, deves mesmo notar qq diferença entre ser a PS3 a descodificar o som ou um receiver a fazer esse decode.
E so mesmo se tivesses um receiver muito caro é que talvez notasses qq diferença...
Se sair o decode do DTS-HD MA na PS3, caga mas é nessa ideia e compra um PS3!!

Se sair Nuno, se sair. Depois chamem-me picuinhas, chame-me o que quiserem. Mas não ver no receiver novo, que eventualmente comprarei, no visor a nominação True HD DTS HD, mas sempre Multichanel ... ná

Many of you asked for it, and this week you got it, thanks to Home Media Magazine's Nielsen VideoScan numbers, we now know how the favorite HD home movie format compares to the reigning home media champion. Sure, 6 percent isn't that much, but it's more than most people thought it was, but to be fair it is only taking into account the top 20 BDs vs the top 20 DVDs. This is an interesting way to compare the two formats as seven out of the top 20 -- three in the top 10 -- DVDs aren't available on Blu-ray, but DVD has many more releases than Blu-ray, so while the angle is obviously in Blu-ray's favor, it'll become even more true, as more Blu-ray titles are released day-and-date with DVDs. Looking back at our old fight, HD DVD's last exclusive is now done and gone and as expected, HD DVD has its worst week ever, but with the recent events we only expect this to get worse, and wonder how long HMM will continue to compile results. The other indicator that it's officially over -- as if we needed another -- is the lack of a single HD DVD on the HDM top ten chart. Not even HD DVD's last exclusive could make the list, but Blu-ray's latest didn't have any problem killin' the competition as I Am Legend destroyed Disney's Enchanted by almost four to one. The other interesting thing about this week's chart is that most of the rest of the 10 ten is made up of oldies, which makes us want to know; where are all the sales?

Here we are two weeks into the new Nielsen VideoScan charts courtesy of Home Media Magazine, and Blu-ray has managed to increase its share from 6 percent to 8. This was mostly due to the super hot I Am Legend that has once again dominated both the High-Def Sellers list, as well as the DVD charts. The big missing title for Blu-ray this week was The Mist from the once Red exclusive studio Weinstein. So while Weinstein has been quite about its HD plans, this new release takes the number two spot on the DVD charts. This is only one of eight titles that makes the DVD top 20 list, but isn't available in HD. Meanwhile, half the titles on the HD top ten are older titles, so no doubt promotional sales are making the difference here. HD DVD didn't make the list, but did manage to regain some market share overall -- but not much. We'd be very surprised to see that become a trent as the format is officially out of exclusive new releases. At the same time, we'd be surprised if Blu-ray was able to keep its 8 percent share next week considering the lineup, but sometimes catalog titles sell so well, Blu may prove us wrong.
