    • In order to eliminate image defects produced by high-energy particles passing through an image sensor, with signal scrolling and integration, the method involves upstream detection, on the digital values supplied by the pixels of a same row having successively observed a same scene point. Said detection makes it possible to ignore or correct the values from corrupted pixels in the establishment of the digital signal representing the luminance of an observed scene point. The detection is based on calculating the difference between a first digital value P
      i,a (t
      1 ) and a second digital value P
      i,b (t
      2 ) provided by two pixels Ρχ
      i,a and Px
      i,b having observed the same scene point, subtracting the second value from the first, and comparing it to a predefined threshold k. If said difference is greater than the threshold, the first value is too high, and the first value is ignored in the summation ∑'
      i carried out in order to establish the luminance of the scene point, said value being replaced with the second value with which it has been compared. In one alternative, the first value is replaced with an average value; or is excluded from the calculation.
    • 为了消除由通过图像传感器的高能量的粒子产生的图像缺陷,具有信号-滚动和集成,该方法包括上游的检测,在由同一行的像素提供具有依次观察相同场景点的数字值。 所述检测使得可以忽略或在建立代表观察点的场景的亮度的数字信号的校正从破坏的像素的值。 所述检测是基于计算由两个像素Ρχi,a和PXI提供的第一数字值裨,一个(t1)和一个第二数字值裨,B(T2)之间的差值,b。具有观察到的相同场景点,减去 从第一第二值,并将其与预定的门限值K。 如果所述差大于阈值,第一个值过高,且第一个值是为了建立现场点的亮度进行了总结Σ'i忽略,所述值与第二值替换为 它已进行了比较。 在一个替代方案中,所述第一值被替换为平均值; 或从计算中排除。

    • A system and method for system and method for video distribution over a range of devices over Internet Protocol (IP) networks are provided. The system and method provide for connecting to the network at least one additional content source, communicating a first request over the network, the request requiring each of the plurality of content sources to identify channels on which each of the content sources provides content, and selecting a channel not being used by the content sources to provide content. The method and system may also provide for connecting at least one client to the network, communicating a second request over the network, the second request requiring each of the plurality of content sources to identify channels on which each of the plurality of content sources provides content, selecting an identified channel by the at least one client, and providing content to the at least one client on the selected identified channel.
