Programmable Receiver for a Multi-Media System

      Disclosed is a programmable television receiver which includes
full motion video processing capability.  The two main sections of
the receiver, as shown in the Figure, are RF tuner section 10 and
media bus interface section 12.

      RF tuner, section, 10 includes a family of different tuner
modules 14, which allows the programmable receiver to receive and
demodulate compatible television signals in all of the currently
utilized formats.  The NTSC, PAL, and SECAM formats are the
conventional television formats used in different parts of the world.
The MUSE HDTV, US HDTV, and HD-MAC formats are for high- density
television.  The SMPTE, CCIR-60i, and Multi-Vid modules allow
operation in a studio mode with multiple video cameras, etc.  Each of
the tuner modules provides, as its output, a common format digital
video and attendant audio signal.  Since RF tuner section 10 is built
in accordance with a modular concept, new formats can easily be added
by developing new tuner modules 14 as they become necessary.

      The output of RF tuner, section 10, is fed directly along a
media bus 16, into media bus interface section 12, which provides the
interface between section 10 and the rest of the multi-media system.
In interface section 12, signals from media bus 16 are processed by
bus interface module 18 to be transmitted along a local
analog/digital bus 20 to an integrated micro- controller 22, which
controls al...
