A individual expert within the art will derive many methods from explanation above and the three examples mentioned below. Figures 6b and 6c are schematics of the components of alternative embodiments for a digital cable headend. DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic of an present analog cable television supply system. It is an object of this invention to supply a cable headend that decrypts indicators received in various encryption codecs and encrypts all signals transmitted to viewer properties into one encryption format. A variety of analytical and statistical methods could also be used to determine the precedence of the FIFOs 156 for sequencing. These commands will embody which video signals should be chosen and different information such because the kinds of indicators , whether or not the video is encrypted and the encryption methodology used, and so forth.

Depending on the precise embodiment, the television program sign could must be compressed, combined/multiplexed, encoded, mapped, modulated, upconverted and amplified. Each transponder is just capable of handling a single analog television program at a time. The acquired analog tv program alerts are combined by the cable headend 34 and routed to the concatenated cable system 32. The one program per transponder limitation of the analog television delivery system could be eradicated with the introduction of digital technology. In the popular embodiment, two-way communications between the network controller 304 and set high terminal 58 will happen over cable strains. Interactive tv programming could be accommodated through the community controller 304.

Although uplink sites and satellite dishes can transmit and obtain a number of video/audio program indicators, presently, every satellite transponder usually carries just one video/audio program at any given time. Further, there is typically one Integrated Receiver and Decoder per transponder on the analog cable headend to receive the signal from the transponder.

42 with a Combiner 104 that solely handles digital television programming alerts 103.

Since the video sign's MPEG packets are addressed, each FIFO 156 is assigned to obtain sure video packets in MPEG format that have the suitable tackle assigned to that FIFO 156. This embodiment additionally offers for remote management of the Control CPU ninety by modem 116. Many compression techniques corresponding to MPEG can be found and can be used with the current invention. What is needed is a cable headend that can handle any essential sign encryption or decryption. Figure 10c shows a easy example of how the overflow situation may be handled with software on the Control CPU ninety. This subroutine 224 should decide which packets of video/audio information are to be deleted and what quantity of packets are to be deleted.

Each vendor makes use of scrambling strategies which are incompatible https://foxz89.com/tag/สล๊อตpg with the every other vendor. There https://foxz89.com/tag/เว็บ-เล่นเกม are two major cable trade leaders in scrambling formats, Scientific-Atlanta, Inc. , 4386 Park Drive, Norcross, GA and General Instrument Corporation, Gerald Communications Division , 2200 Byberry Road, Hatboro, PA 19040. The Control CPU 90 of figure 6a may be instructed by a remote site (e.g., a nationwide site) via a modem 116 or related connection. Alternatively, as an alternative of enabling the https://foxz89.com/tag/สล็อต-joker-2 outputs of the demultiplexers 120, the inputs of the Combiner 104 could additionally be selected by the Control CPU 90. By enabling or deciding on multiplexer outputs, the Control CPU ninety is able to control which tv packages are combined and transmitted to the viewers.

Analog cable television supply systems operate with an analog cable converter box in the viewer residence which makes use of a television to display video programs. To carry out its features, the community controller 304 should work closely with the sign processing system 300. In many instances the info sign obtained from the Operations Center fifty six should be modified previous to being sent to the set prime terminals. These modifications to the program control data are made by the network controller 304 working along side the signal processing system 300 to send a set high terminal 58 management information stream .

What is needed is a cable headend that can combine varied digital video/audio indicators to create tiered program offerings for viewers. What is needed is a cable headend which receives multiple https://foxz89.com/tag/โปรสล็อต-100 video/audio program signals from a single satellite transponder. In addition, at present's cable tv delivery systems carry indicators which are scrambled for security reasons.

In a easy embodiment, this system management data sign could be handed via the cable headend 42 to the set high terminal 58 with none modifications. ADVANCED EMBODIMENT Figures eleven shows an overview of the operation of a more advanced program delivery system 40. Figure 12 is a schematic of the popular embodiment of a digital cable headend 42 to assist the more advanced program supply system forty.

Figure 9a reveals the precise hardware of the Combiner 104 in an embodiment which makes use of IRDs 86 and a QAM 102. Figure 9b exhibits the output management logic one hundred ninety which may be situated remotely from the Combiner 104. In the preferred embodiment, the output control logic a hundred ninety is situated between the Control CPU ninety and Combiner 104.

for a cable headend which combines digital video/audio indicators of various data charges. It is an object of this invention to provide a Combiner component for a cable headend which mixes digital video/audio alerts obtained from two different transponders. It is an object of this invention to supply a Combiner https://foxz89.com/tag/สล็อต-kub part for a cable headend which combines digital video/audio indicators and analog video/audio signals. It is an object of this invention to supply a digital cable headend for a cable tv supply system.

Those outputs of the multiplexer which might be enabled are then enter to the Combiner 104. For this primary method, a central Operations Center 56 should divide this system sign into three parts and ship a separate leading header earlier than every sign for every half. This technique requires the extra signal overhead of a header on this system sign. There are several methods by which the cable headend forty two could strip the pointless indicators.

In this fashion, a single digital program could additionally be selected from a transponder 52 carrying multiple digital packages. Priority two tv programming is not accepted by the cable television system whose digital capability is the smallest, or in this case, the 48 mHz system 60. Priority two tv programming is accepted and utilized by the 2 bigger capacity cable television techniques shown sixty two, 64 respectively.
