It is valid for all DVB and ATSC types (valid ones are DVB-S
(satellite), DVB-C (cable), DVB-T (terrestrial) and ATSC (the American
version)). Even Conditional Access is available and works for all these
types. DVB S2 (Satellite version 2) and DVB H (mobile) is on the way, so
is basic DSS support. And the libs are valid for _any_ MPEG2 TS
application. With the exception of DVD's (DVD's use Program Streams
instead of Transport Streams) etc, basically we use a TS in many
situations as a TS is more robust than a PS in all aspects. One can
convert TS's to PS's quite easily.
Personally doing DVB-S2 and DSS API support ATM.
The issue with Xine is that it doesn't make use of PCR's and thus has
MPEG2 decoder problems with Transport Streams. Watching Transports
streams on Xine continuously ~24 hrs the ringbuffer underrun occurs (at
PTS wraparound, since PTS is a 33 bit value) and one sees all nonsense
(causing a rebuffering and this can be seen as breaks in the output
video). Basically a major design issue in the player, which is well
known and hence is "not" preferred for high availability applications.
There are many ways in which these issues can be solved by using filters
like the Kalman and H-Infinity filters. Soon we may see applications
based on these filtering algorithms.
