In addition, in the EPG recommendation page switching platform, the method further includes: and the frequency division duplex communication equipment is connected with the personnel identification equipment and is used for receiving the personnel patterns and counting the number of the personnel patterns to obtain the number of real-time people so as to wirelessly transmit the number of real-time people in a frequency division duplex communication mode.
Frequency division duplexing means that uplink and downlink transmissions are made on different frequencies, respectively. In the frequency division duplex mode, the uplink and downlink transmissions are made on different frequencies, respectively.
In the first and second generation cellular systems, FDD technology is basically used for duplex transmission. In particular, in the first generation cellular systems, since continuous baseband signals are transmitted, duplex uplink and downlink channels must be provided using different frequencies. In the first generation cellular systems, in which FDD is used for continuous information transmission, frequency synthesizers for generating different carrier frequencies are required at both the transmitting and receiving ends, and a duplex filter for preventing the transmission signal from leaking to the receiver is required at the receiving end. In addition, in order to facilitate the fabrication of the duplexer, a certain frequency interval is required between the transmission and reception carrier frequencies. In the second generation of systems such as GSM, IS-136 and IS-95, FDD technology IS also used. In these systems, since the information is transmitted in time slots, the transmission and reception can be performed in different time slots, and the transmission signal of the mobile station or the base station does not interfere with the receiver. So, despite the FDD technique employed, no expensive duplex filters are required.
The FDD mode is characterized by receiving and transmitting in two symmetric frequency channels separated (190 MHz between uplink and downlink frequencies), and separating the receiving and transmitting channels by guard bands. By adopting the technologies of packet switching and the like, the bottleneck of the second generation development can be broken through, the high-speed data service can be realized, the frequency spectrum utilization rate can be improved, and the system capacity can be increased. FDD must provide third generation services using paired frequencies, i.e., within a bandwidth of every 2x5 MHz. The mode can fully utilize the uplink and downlink frequency spectrums when supporting the symmetric service, but the frequency spectrum utilization rate is greatly reduced (about 40 percent of the frequency spectrum utilization rate is reduced due to low uplink load) when the asymmetric packet switching (Internet) works, and in this regard, the TDD mode has incomparable advantages compared with the FDD mode.
By adopting the EPG recommended page switching platform, aiming at the technical problem that the corresponding EPG page style cannot be determined according to the average age of the people watching the television at present in the prior art, the EPG recommended page of the set top box is subjected to detailed management, and the corresponding EPG page style is determined according to the average age of the people watching the television at present; more importantly, in the specific image processing, the characteristics that the performance of eliminating edge noise by using corrosion expansion processing is superior to that of opening and closing operation processing, and the detail of a protection target of the opening and closing operation processing is superior to that of the corrosion expansion processing are utilized, on the basis of analyzing the noise distribution condition of the image, a morphological processing mechanism based on the image content characteristics is established, and various defects caused by the originally rigid image processing mechanism are overcome; thereby solving the technical problem.
It is to be understood that while the present invention has been described in conjunction with the preferred embodiments thereof, it is not intended to limit the invention to those embodiments. It will be apparent to those skilled in the art from this disclosure that many changes and modifications can be made, or equivalents modified, in the embodiments of the invention without departing from the scope of the invention.
