Though, decoding itself is particularly difficult to just PS3 which loads Cell where also 7 are built in, with cannot think SPE which is the processor whose stream processing is proud. To H.264 because there is the transaction of operation which cannot do concurrent processing, it is certain for software decoding with the general-purpose processor to be heavy, but suffering hardship in some point?
"Certainly Cell is the processor which faces to stream processing, but very careful optimization is necessary. As for decoding itself it reached the point where it can do directly, could put out also image directly. That, from first real time decoding being possible, at this point in time about SACD playback was not serious ",
But ", at that time because it is not visible completely, using the video transfer zone of 40Mbps in full, the specification of BD-ROM how becomes, advancing development with the rather high goal whether 2 streams it can play back the H.264 image of full HD simultaneously, hurting, it does. Because with BD the image stream can be handled 2 systems simultaneously, at most in parallel 2 the stream of full HD, you must decode. Furthermore as for the machine for development there is also a circumstance that "it was moving at only the clock frequency which is lower than the end product,
So at present time, as for the H.264 image stream of full HD, it will be operational by some load? To tell the truth SPE5 which is necessary with decoding processing at the time of SACD playback it is much lower than ability of amount, you say that SPE3 processing is possible by load of amount. As for this, there is a sufficient thing which the preparation carefully repeats preparation.
But, thing and the high picture quality which can be played back/high quality being the player is different. Also the point where several should improve was seen in the BD player and the DVD player who are included in the firmware at writing point in time. Concerning those are improved in the future, how, it tried hearing.
