Hello, there
I am studying DVB-H and have these questions. Hope any of you could
throw some light on them.
1) If MPE-FEC is used, the receiver would need two RS decoders,
RS1(255,191,64) and RS2(204, 188). The result of RS1 is scrambled
and fed to RS2. Is my understanding right?
2) With Time Slicing. how is boundary of two adjacent bursts is treated
in the outer-interleaver? Will the data at the boundaries of two bursts get
mixed up? One receiver only takes one of the burst. how can it sort out
the interfering data from adjacent bursts?
I didn't find any clause in EN.301.192 indicating each burst is interleaved
independently in the outer-interleaver.
3) Spec EN.301.192(2004.06) doesn't explain the Table Boundary and
Frame Boundary, etc. I saw them on
**broken link removed**.
Do I miss out a specification?
4) MPE and Time Slicing are compulsory in DVB-H, while MPE-FEC
shall be made bypass-able, am I right?
Thank you!
