Provider and Network fields is the same.

4.9.3 Decoding MPEG-2 / DVB Channels, access to Digital Services.
The MPEG-2 is an ISO/IEC (13818-1) standard that defines the audio and video
multiplexation in chains of bits form, grouped in fixed length packets. These standards
offer two multiplexation layers: the first one (Packetized Elementary Stream) manages
the synchronization between video and audio, whereas the second one depends on
used transmission media. For error-free medias, this layer is the Program Stream,
whereas at not error-free medias is called Transport Stream.
