    Abstract: A film-to-video format detector (24) for a digital television receiver (10). The detector (24) receives pixel data from a current field and a second preceding field. It determines a set of pixel difference values, sums them to obtain a field difference value, and compares the field difference value to a threshold. These steps are repeated to obtain a series of field difference indicators. This series is analyzed to determine whether it has a pattern corresponding to a film-to-video format.

    Abstract: A method of adjusting color temperature of images displayed by a display system (10) whose images are based on sequential pixel data and are filtered with a color wheel (15, 15', 15''). The relative display times for each color are adjusted to result in a corresponding adjustment of color temperature. In a first embodiment (Figure 2), the size of the color wheel's segments are changed as well as the display times for data corresponding to each segment. In a second embodiment (Figure 3), the display times for data corresponding to one or more segments are decreased with a black display time to fill in the difference.

    Abstract: A digital television system (10) is provided. System (10) may receive a video signal at composite video interface and separation circuit (16). The video signal is separated into component form by composite video interface and separation circuit (16). The component video signals are converted to digital component video signals in analog to digital converter circuit (18). Line slicer (14) divides each line of digital component video signal into a plurality of channels such that each channel may be processed in parallel by channel signal processors (22a) through (22d). Each channel signal processor (22a) through (22d) may provide two lines of output for each line of video input. The processed digital component video signals may be formatted for displays (26a) through (26c) in formatters (24a) through (24c). Each formatter (24a) through (24c) may comprise a plurality of first in-first out buffer memories (34a) through (34j). One of each channel signal processors (22a) through (22d) may be coupled to two of first in-first out buffer memories (34a) through (34j). Additionally, each formatter (24a) through (24c) may comprise channel data format units (38a) through (38d), each associated with a channel of, for example, display (24a). Channel data format units (38a) through (38d) are coupled to appropriate of first in-first out buffer memories (34a) through (34j) via multiplexers (36a) through (36d). Each formatter (24a) through (24c) may remove overlap between channels of system (10) and may format the processed video signal into appropriate channels for displays (26a) through (26c).

    Abstract translation: 提供数字电视系统（10）。 系统（10）可以在复合视频接口和分离电路（16）处接收视频信号。 视频信号由复合视频接口和分离电路（16）分离成组件形式。 分量视频信号在模数转换器电路（18）中转换成数字分量视频信号。 线路限幅器（14）将每行数字分量视频信号划分为多个通道，使得每个通道可以由通道信号处理器（22a）至（22d）并行处理。 每个通道信号处理器（22a）到（22d）可以为每行视频输入提供两行输出。 经处理的数字分量视频信号可以格式化为在格式化器（24a）到（24c）中的显示器（26a）至（26c）。 每个格式化器（24a）到（24c）可以包括多个先进先出缓冲存储器（34a）至（34j）。 每个通道信号处理器（22a）至（22d）中的一个可以耦合到两个先进先出的缓冲存储器（34a）至（34j）。 另外，每个格式化器（24a）到（24c）可以包括通道数据格式单元（38a）至（38d），每个与例如显示器（24a）的通道相关联。 信道数据格式单元（38a）至（38d）通过多路复用器（36a）至（36d）耦合到适当的先进先出缓冲存储器（34a）至（34j）。 每个格式器（24a）到（24c）可以去除系统（10）的通道之间的重叠，并且可以将经处理的视频信号格式化成用于显示器（26a）至（26c）的适当通道。

    Abstract: A system (10) for processing pixel video data having a selectable number of bits is provided. The system (10) comprises first, second and third video processors (12), (14) and (16). The first video processor (12) receives and processes pixel data of a luminance video signal. The second video processor (14) may receive and process pixel data of a chrominance video signal and may generate one of first, second and third video signal outputs. The third video processor (16) may process the chrominance video signal and may also generate at least two of the output video signals.
