[linux-dvb] [PATCH] Uniquely identify unknown services

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Here's a very simple patch to scan that I've found useful while
playing around with my new Fusion HDTV card.  If scan detects a
service that can't be named, it generates one based on the service_id.
This can leas to duplicate names in the resulting channels file if
unnamed services are found on different frequencies with the same
service_id.  This patch remedies the problem by prefixing each
generated name with a unique number.
