A handful of people have asked about current and future support for the SAA7164 features. Digital TV, Remote control, Analog, VBI, FM Radio, Raw Video and Encoded video for NTSC, PAL and SECAM. Firstly, thank you for writing. Second, I thought it would be useful to outline the current status and future roadmap for the driver.
Today, the only supported features of the HVR-2200 and the HVR-2250 products are the digital TV inputs. So, if you have access to DVB-T signals in Europe or Australia, or you’re lucky enough to be able to receive ATSC or Digital Cable (QAM Annex-B) in North America, Mexico or Canada then one of these two boards would be useful to you. You’re in luck. The HVR-22×0 series products are dual tuners so you can use both digital TV tuners independently and concurrently.
Today, if you need analog TV support (US cable comes to mind), remote control support, VBI / Closed Captions then you’re out of luck. The driver has no support for any of these features.
Generally speaking, the current driver is fairly stable for a large number of people but a handful are experiencing a full system lockup. I’m covering that separately on the blog so I’ll skip the detail here. Importantly, I have no plans to develop new driver features (analog etc) until we get digital TV support reliable and stable across all platforms, including 32 and 64bit. Why? It’s a question of overall quality and currently it’s not high enough for the Kernel Labs seal of approval.
Work is progressing on the driver. In the coming days / weeks I’ll isolate then fix the hang and prepare the driver for another round of testing, followed by requesting merge into the master repositories at linuxtv.org. Once this is complete then we’ll review the other missing features and outline a roadmap for implementation.
The long-term goal is to have all of the missing features working in the driver, where possible.
