Linux support for digital video broadcasting
Mauro Carvalho Chehab, the maintainer of the kernel's media subsystem, has
posted the first two in a series of articles on digital video broadcasting
support in Linux. Part 1
gives an overview of how the devices and protocols work, while part 2
looks at digital TV network interface use. "Supporting embedded
Digital TV hardware is complex, considering that such hardware generally
has multiple components that can be rewired in runtime to dynamically
change the stream pipelines and provide flexibility for things like
recording a video stream, then tuning into another channel to see a
different program. This article describes how the DVB pipelines are setup
and the needs that should be addressed by the Linux Kernel."
