Welcome to the linuxtv.org V4L-DVB Wiki !

This wiki is intended to become an authoritative source of information regarding the use of analog video and digital TV sources under Linux -- i.e. the subject matters covered under the V4L-DVB framework. The basic plan is to aggregate information about: available hardware; how v4l or dvb work; software used with the hardware and so forth. Like all other wikis, the V4L-DVB wiki relies upon the contributions of its users. Hence, it will only be as useful as we make it! So we encourage you to share your knowledge and help with the task of turning this site into a grand repository of knowledge. Your input (whether it be by providing a set of instructions for how to get a certain device working; a minor improvement to an existing article; or an explanation for some complex concept) will be highly appreciated. -- The LinuxTV V4L-DVB wiki team / People behind V4L-DVB

IMPORTANT NOTICE: Hi everyone, the merger of the V4L and DVB wikis is now underway! Articles within the V4L wiki will progressively be transferred into this wiki. Please see here for the important details.
