A company that developed the first widely available PVR
product. Their name is becoming synonymous with PVR

describe something as a TiVo unless it is a TiVo-manufactured
PVR, and describing products by other manufacturers as 'TiVo
like' is also considered detrimental. These PVR devices are also
sometimes known as DVR devices, since they operate with
digitized video even when their I/O is analogue.
On a Digital Satellite system (DSat), the transport stream is
delivered one per transponder. Each transponder is quite

Data messages embedded in streams can carry event-based
information to cause things to happen in the client device.
