Re: USB HDD Drive recording
Hello! Actually I don't have D-series TV but I was analyzing SRF file recorded by Samsung BD-D6990 PVR-ready blu-ray. This is what I got to know:
1. SRF file is TS file with partially scrambled contents.
2. There is no file header. File consists of number of packets without any gaps between.
3. Each packet is 188 bytes long (as in TS file): 4-byte for header, and 184 bytes of payload.
4. Each packet starts with 0x47 byte and 2-byte-PID-number so it seems that packet's header is not scrambled.
5. EPG packets (EIT,ST) aren't scrambled.
6. PMT and PAT packets aren't scrambled.
7. Audio and video packets are scrambled.
9. There are 2 smaller scrambled files stored together with SRF file (CKF, ENC). Other additional files (MDB, INF) probably are not scambled.
10. Timeshift file is scrambled.
BTW, I don't know why Samsung decided to scramble user's recordings (even FTA ones!). There are many devices on the market that doesn't scramble recordings made on external USB. I think Samsung is (or will be) loosing customers by such ideas.
