Title: Automatic gain control
IPC: H03G3/20
Filed: 1972-03-03
Abstract: 1374540 Automatic gain control; limiters PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 March 1972 [6 March 1971] 9996/72 Headings H4R and H3T A threshold circuit for use in an automatic gain control arrangement includes a first transistor to the base of which a gain controlling signal is supplied and to the emitter of which is connected the parallel arrangement of a rectifier, e.g. a PN junction, and the base emitter junction of a second transistor, first and second gain controlling voltages being derived from the collector potentials of the first and second transistors respectively. The arrangement is such that the first and second gain controlling voltages are produced over different ranges of variation of said gain controlling signal supplied to the base of the first transistor. The circuit is shown as used in the gain control for a television receiver having RF and IF stages designated 22 and 15 respectively. Connected to the IF stage is a detector circuit 27 for producing a gain control signal in dependence on the signal level produced by the IF stage. When the output of the IF stage is at its required level the gain control signal is at its highest level resulting in transistors 3 and 7 being bottomed, i.e. turned hard on. The gain control voltages at points 9, 17 are therefore substantially zero. However, as the gain control signal at the base of transistor 3 is decreased the potential at terminal 9 drops and a gain control voltage is supplied to IF stage 15 of the receiver. By choosing the surface area of the base emitter junction boundary of transistor 5 connected to operate as a diode to be about a sixth of that of transistor 7 it can be arranged that the potential at the point 9 will have increased to 80% of its maximum value before the potential at the point 17 starts to increase, thereby supplying a gain control voltage to the R.F. stage only after the gain of the IF stage has been increased considerably. Fig. 2 (not shown) illustrates a modification to the Fig. 1, circuit for providing a gain control voltage to the RF amplifier which decreases rather than increases, with a decreasing gain control signal applied to transistor 3. This is accomplished by connecting the collector of transistor 7 to the parallel arrangement of a fourth transistor (23) connected as a diode and the base emitter junction of a fifth transistor (25). The gain control voltage for the RF stage is then derived from the collector of the fifth transistor. The circuits may be made in integrated circuit form and an external variable resistor may be provided for altering the stage of operation at which the potential for controlling the RF storage starts to increase (or decrease).

IPC: H04N5/45
Filed: 1991-09-17
Abstract: An interactive videotex system with distributed processing and storage of video picture information in nodes (12) disposed throughout a cable television distribution system. The nodes (12) are coupled to the feeder cable (30) of the cable distribution system. Each node (12) in the system receives a substantially identical copy of the interactive video picture information and related data from a regional processing center (4). The users at home televisions (38) associated with a particular node (12) interact directly with the video picture information in that node (12), rather than with the information stored in the regional processing center (4) or some other remote location, which enables the system to quickly display photographic quality images and complex graphics, as well as sound, at the users' televisions (38) in response to commands received by the users. The nodes (12) can also be used for decompressing compressed television programming and distributing the decompressed programming to home televisions (38) connected to the system. <IMAGE>
