[QUOTE="deeptho, post: 1138366, member: 215446"] I have just uploaded the code for neumoDVB version 1.0. This version has many changes. [B]Important:[/B] [LIST] [*]You will need to use the latest blindscan drivers in order to make use of all features without problems. [*]It is possible to use neumoDVB with the standard TBS drivers, but features such as spectrum scan, blind scan, parallel scan and constellation display will not work. [*]Due to an incompatible change in the database format, you will need to re-enter your LNB and USALS information. Other data, such as services, muxes, ... is preserved. [*]You will need to read the documentation to understand how LNBs should be configured, because this has changed in the new version. [/LIST] The full list of changes can be found here: [URL unfurl="true"]https://github.com/deeptho/neumodvb/blob/master/docs/changes.md[/URL] [B]Some highlights include:[/B] [LIST] [*]New database format: data related to local setup is now stored in anew database, called devdb.mdb Also, the definition of LNBs and frontends has changed to better support new features. As a result of the move, old LNB definitions will be lost and need to be reentered. The remaining database now contain data that is independent of the local hardware setup and can therefore be shared with other users. [*]neumoDVB now makes better use of cards with and RF mux. These cards, such as TBS6909x and TBS6903x have multiple tuners (e.g., 4) and even more demodulators (e.g. 8). The RF mux allow connecting any demodulator to any tuner. This means that all demodulators can reach all connected satellite cables. Also, multiple muxes can share the same tuner and thus tune to multiple muxes in the same band and with the same polarisation simultaneously. [*]neumoDVB can longer needs concepts like "slave tuners" because all tuners can use al RF inputs. So the concept of slave tuner has been removed. [*]Parallel blind scan on supported cards, neumoDVB now uses all available demodulators to scan muxes. This makes blind scanning (almost) 8 times faster on supported cards [*]Parallel SI scanning was already possible in neumoDVB, but now it can exploit more parallelism by setting the RF mux than before. [*]Faster scanning: neumoDVB processes transponders with many (more than 200) multi-streams much faster by detecting streams which are not transport streams. [*]Improved spectrum analysis: very wide band muxes are no longer detected as dozens of very small peaks, but as a single or a small number of peaks. This speeds up blind scanning as well. The estimated symbol rate of peaks used to be very inaccurate and is not more accurate. [*]Change voltage from 0 to 18V in two steps to avoid current overloads when many diseqc switches switch simultaneously. [/LIST] [/QUOTE]
