Foxsat HDR - Recording Buffer

[marc-h]

Does anyone know why the Foxsat HDR can't record from the instant rewind buffer? I understand Humax have said it just isn't possible. What is the actual reason for this? If I switch to a channel and hit the record button there is no delay or slowness, can't the box effectively just do that itself without any of the notifications on screen? I'm sure it isn't that simple but why?

Most likely reason is that if you could then you would be able to record HD without encryption. HD content is written to the timeshift buffer file (0.ts) withi
without encryption. The custom firmware lets you stream this file to a suitable PC so you can watch HD on a PC just behind real time.

That does make sense but what would stop them using the same process as a proper recording for the timeshift buffer so it was encrypted. There doesn't seem to be any noticeable delays so why does the time shift buffer have to be unencrypted?

Because it's a single large file that every time you swap channels it starts recording over the original content, leave it long enough it will start overwriting from the beginning of the file. Handling HD channels without the encryption flag and SD ones directly within the same file is going to get rather complex. HD recordings don't have to be encrypted (BBC1-HD transmitted after launch for a long time without the BBC invoking the encryption flsg). The Humax Freeview+ box does it differently. Everything is encrypted SD and HD. Copying SD content to usb the encryption is removed. Copying SD content to USB is significantly slower than the Foxsat due to the decryption process. As a result buffer rewind recording works on the HDR FOX T2.
