Mediacorp HDTV broadcast sample screen captures

Below is a sample clip I captured using my DVB-T tuner. It is really CPU intensive. With my P4 3.0GHz and a Radeon 9500Pro, the cpu utilisation peaked at 100% and throttles between 65%-100%.

The current trial broadcast is playing back locally produced HDTV clips and also clips from Panasonic and Hitachi. It is also advertising the upcoming HDTV screen of the lord of the rings.

A video card that does native AVC decoding should help such as the ATI X1600

ATI X1600 does not decode h.264 high profile.

so where's the sample clip?

It is on the latest posting

good point on the X1600 and no high profile support. Forgot about that. Must be all the glue I am sniffing lately.

Are there any video cards that support h/w decode of AVC high profile?

hdtv said...

Even if it does, it might not work. Unless the s/w makes use of the hardware acceleration of the GPU, it is still software decoding using CPU.

Basically the software developer must have access to the ATI AVIVO features to take advantage of it to offload the CPU from decoding the h.264 streams.

Seems MediaCorp HDOne does not encrypt since u dont need a smartcard. Can any lucky trial paticipant confirms there is no smartcard on the CI slot of the STB?

The channels are not encrypted at all. So long you can receive DVB-T signals, with the proper hardare you can receiev the HD broadcast.
