摘要： A television system whose full coloured television signal (EM(t)) is formed by the use of reflex-modulated signals (E3(t)), where, at the transmitting side, the quadrature modulation of subcarrier frequencies in the phases ''0'' and ±(π/2) is effected by means of videosignals (E1-1(t), E1-2(t)) so as to form reflex-modulated signals (E3(t)) on the subcarrier frequencies f chosen so that the required phase differences are obtained in the subcarrier frequencies in the neighbouring lines of the same frame and in the numerically identical lines of the subsequent frames, the thus formed reflex-modulated signals being then transmitted within the time intervals of the full coloured television signal (EM(t)) which are provided for them, whereas, at the receiving side, the packages of the reflex-modulated signals (E3(t)) are discriminated from the received full coloured television signal (EM(t)) and delayed in delay units (11) for time intervals which are multiples of the television scanning durations, after which the delayed and non-delayed packages are multiplied by harmonic signals (U1(t), U2(t)) in multiplying units (121, 122), are algebraically added in an adder (13) and then the modulating videosignals (E1-1(t), E1-2(t)) are discriminated from the signals obtained as a result of said adding.

摘要： A digital video transmission system that operates with three different video rendering paths. A first rendering path operates by receiving display requests and rendering bit-mapped graphics in a local screen buffer. The display information in that local screen buffer is then encoded and transmitted to a remote display system that recreates the content of that local screen buffer in a video buffer of remote display system. A second rendering path operates by receiving encoded video stream requests that can be decoded by the remote display system. Such encoded video streams are sent to the remote display system with minimal addition transport encoding. The third rendering path handles encoded video streams that cannot be handled natively by the remote display system. Such video streams may be either transcoded before transmission or decoded and stored within the local screen buffer.

摘要： Television receiver with a receiving section, a circuit for processing a received television signal which preferably contains digital data, whereby the circuit has a selection stage (4, 5), and a measuring circuit (9), which has an output (8), for measuring the signal quality or a measured variable representative for that (quality) like, e.g., signal-to-noise ratio, field intensity, bit error rate, etc, of the received television signal. The selection stage (4, 5) possesses a controllable transmission band (range) and has a control input (6, 7). The control input of the selection stage is connected with the output (8) of the measuring circuit (9). The measuring circuit controls the transmission band of the selection stage depending on the measured signal quality in such a way that upon worsening/improving of the signal quality of the received television signal, transmission band of the selection stage is reduced/increased.

摘要： A method and apparatus for reformatting MAC color television signal to reduce bandwidth. Chrominance and luminance components are serially arranged on a line by line basis with the luminance component not compressed or minimally compressed. The aspect ratio is reduced from the standard aspect ratio by a gate (5) which truncates the edges and feeds the MAC signals into memories (10, 11) for subsequent time expansion. Since a normal television picture tube overscans, the edges of the picture are never displayed and need not be transmitted or recorded. The reformatted signal can be made compatible with a standard composite signal by merely expanding (22) and modulating the chrominance and adding to the luminance (25). The compatible signal has a shorter active video time and a smaller aspect ratio.
摘要翻译：一种用于重新格式化MAC彩色电视信号以减少带宽的方法和装置。色度和亮度分量与未压缩或最小压缩的亮度分量逐行排列。宽高比通过栅极（5）从标准宽高比减小，该栅极截断边缘并将MAC信号馈送到存储器（10,11）中以用于随后的时间扩展。由于普通电视显像管过扫描，图像的边缘从不显示，不需要传输或记录。重新格式化的信号可以通过仅扩展（22）和调制色度并添加到亮度（25）而与标准复合信号相兼容。兼容信号具有更短的有效视频时间和更小的宽高比。

摘要： Chrominance component signals of two different types are produced such that the chrominance signals alternate within a field and between adjacent fields in order to provide an improved amount of information from which to enhance the vertical chrominance resolution of a television receiver. The appropriate chrominance structure is either provided by a special source or else a conventional source is filtered in order to produce the appropriate structure. The filter comprises two portions, one for filtering chrominance signals of a first type from a first field and one for filtering chrominance signals of a second type from the first field in order to provide interpolated signals. A specific filter structure is disclosed which may be used for either pre- or post-filtering.
