Okay, so first of all, for getting a second source for our customers, obviously all our customers probably want to look for second source today. But if that’s you have kick off project to switch a different sensor at this point usually to three to four months of a project because we need to redesign the hardware, get a new sensor, new build, and after you get it done, we have to go in there to reach the video quality for that particular set. So that’s three four months delay. I really don’t think that at this point getting a second source will improve this short term problem. I think moving forward with our customer demand, second source is different question but I do say that Sony provides probably the best solution for the -- especially for the high end sensors, if you look at all of the high resolution 4K sensors that our customers using, majority of them are Sony based. So, it’s going to be ongoing problem, we’re going to continue to talk to our customer. But to solve this short term problem, changing sensor is not really option here. In terms of competition, I think in general, in the last three months, we don’t see the competitive landscape changed at all. For HiSilicon, we still that it’s our major competitor in IP camera. And the one thing we did is after we introduced our S3L and S3LM HEVC solution, we have a lot of design win momentum and that’s why we believe that we have a strong HEVC roadmap for our customer for IP security camera now. And for the Qualcomm [ph] competitive landscape didn’t change that much either, although they continue to try to approach our customer on the drone side, but I think they still either focus on the high end drone products like control [ph] portion, not a video portion or for a low end drone, they try to do a total solution. But, in our current latest roadmap to our customer that we show A12 and A9ES and H2 could cover on low end to mid end, to high end, we have a complete roadmap to grow against our competitors. So, in quick summary, in the last three months, we don’t see the composition landscape changed.
