Topfield creates Personal Video Recorders (PVR), which can be used to receive and record digital television channels. Also music (MP3) can be listened with Topfield products. Topfield features can be enhanced and corrected with TAPs (Topfield Application Programs). It is for example possible to watch digital camera images (e.g. jpg) and timers can be created automatically by search words using TAPs. It is also possible to correct bugs with 3rd party patches. This site lists all TAPs and patches developed for Topfield.


HDD Patch [H] V3 and test TAP

This patch module can be installed with Firmware Patcher.

Removes a stupid spin-down/spin-up in the boot sequence.

DeadBeef:
"For whatever reason, Topfield initializes the standby timeout period of the harddisk with the WIN_STANDBY (0xE2) ATA command followed by WIN_IDLE (0xE1). My 80GB Samsung HDD reacts to this command sequence with an audible spin down / spin up which delays the availability of the HDD by a couple of seconds.

So I patched the TF5000 FW with respect to the harddisk initialization. That is, I just replaced the WIN_STANDBY (0xE2) with WIN_SETIDLE1 (0xE3) which sets the standby timeout without putting the HDD to standby immediately. This decreased the boot time by 4 seconds. Many users from the German board confirmed the improvement. However, this value depends on the HDD model. Newer/bigger Samsung HDDs handle the commands faster so that the patch benefit is not that significant. Seagate HDDs seem not to care about the initialization sequence (almost no difference measured)."
