Backhaul logs
TiVo Stream can send logs back to the TiVo Service for troubleshooting just like any other TiVo box.
These logs are known as “backhaul” logs. TiVo Stream can send backhaul logs to the TiVo Service
only when the backhaul flag is enabled for that device. TiVo can enable this flag upon request.
If backhaul logs are desired for a particular TiVo Stream, make a request to TiVo through the
Enterprise Portal.
Functional architecture
This section describes how the TiVo Stream components—TiVo Stream, TiVo Premiere series DVR,
and Apple iOS mobile devices—interact with each other in the home.
How TiVo Stream components interact in the home
When fully installed and set up in the home, the TiVo Stream communicates and interacts in the
following way:
 The TiVo DVR sends high bit-rate MPEG2 recordings to the TiVo Stream via a hardwired
connection.
 The TiVo Stream transcodes high bit-rate MPEG2 into a low bit-rate MPEG4 format.
 The TiVo Stream wirelessly sends the low bit-rate MPEG4 video content to the Apple iOS
mobile devices.
Network communication path
The components are connected to the local network as follows:
 TiVo Stream: Hardwired to the wireless router.
 TiVo Premiere series DVR: Hardwired to the wireless router.
 Apple iOS mobile devices: Connected to the router wirelessly.
Figure 1–4 below illustrates TiVo Stream’s network communication path, from the TiVo DVR to the
wireless router via an Ethernet or MoCA connection, and then from the router to the TiVo Stream.
One or two Ethernet to Coaxial bridges (ECBs) may be necessary to connect the TiVo DVR via
MoCA.
