f Creative is a digital wireless audio and video transmission and display device, which can accept various program contents at any time, and the audio and video data must be stable and not easily interfered. See the first figure for a block diagram of the structure of the device. A portable radio frequency transceiver 1 has an antenna 15 and can receive radio frequency signals.

M272316 IV. Creative instructions (3) Process it into digital video and audio signals and convert digital control signals into radio frequency signals. A flat display 1 2 can receive digital video signals output by radio frequency transceivers 3 and display the images to the user for viewing. , Two la 17, 17, can receive digital sound signals and play the left and right channel sounds, an infrared receiver 14 can receive infrared signals and convert them into digital control signals before transmitting to radio frequency Transceiver 1 3. The portable TV 1 is located in the wireless area network (WLAN) covered by the 802.1la transmission standard. Users can use the remote control (not shown in the figure) of the portable TV directly to the portable TV. 1 For remote control operation, the infrared receiver 14 transmits the signal to the radio frequency transceiver 13 after receiving the operation signal, and the radio frequency transceiver 13 transmits wirelessly via the antenna according to the 80211a wireless LAN protocol. 5 Transmission starts receiving TV program signals. Portable TV 1 then uses antenna 15 to receive radio frequency signals in the local area network. After processing by the radio frequency transceiver 丨 3, digital video signals are generated. Digital video signals include video signals, left channel signals, and The right channel signal, the video signal is transmitted to the flat display 12 to display the program content for the user to watch, the left channel signal and the right channel signal are transmitted to the two speakers 丨 7, 17, play the sound The flat display 12 may be a liquid crystal display or an organic light emitting diode display (0LED), or a conventional projection display. Lu ^ Please refer to the second picture for a schematic diagram of an application block of this creation, usually a digital entertainment center used in ordinary households, including portable TV 1, DVD projector 3, set-top box 4, and video control box 2. The third is a block diagram of the structure of the video control box 2. The video control box 2 includes an M272316 g on page 7 and a description of the creation. (4) The radio frequency transceiver 23 can transmit and receive radio frequency $, A video switcher 2 1 can switch between different video sources and an infrared transmitter + number to the so-called projector 3 and set-top box 4, | \ 243 can transmit infrared signals nu Y 砚 Al source is from DVD recorder 3, set-top box 4. The video signal and sound signal or TV program signal transmitted by the TV antenna or cable TV station to the video control box 2. In the second picture, the portable TV 1 and the video control box 2 are connected by a wireless LAN. The network structure of the basin is 802.1 1 a transmission standard. The video control box 2 is a wireless network console, and the radio frequency is transmitted and received. The device 23 calls other devices with a radio frequency transceiver. If the user wants to watch video programs in the home kitchen, the portable TV 1 will be turned on. 'When the portable TV 1 is turned on, it will send a message requesting connection, the video control box 2 After receiving the message requesting connection, the connection is established. When the user operates the TV remote control to choose to watch the TV station program, the infrared receiver M receives the signal from the TV station and transmits it to the video control device 2 via the RF transceiver 丨 3. After receiving the control signal, the radio frequency transceiver 23 sends the video signal ^ to the video switcher 21, and after receiving the signal, the video switcher 21 switches to the cable television signal to receive the TV station signal, and the TV station signal is transmitted to the radio frequency. The transceiver 23 is transmitted via radio waves, and then transmitted to the flat-screen display 12 via the microwave transceiver 13 of the portable TV 丨 and displayed on the flat panel display 12 via the regulator. Watch TV programs transmitted by cable TV stations or watch TV programs received by TV antennas. In another use case, when a user operates a DVD player to watch the contents of a DVD disc, the infrared receiver 4 receives the DVD player The control signal transmitted by the remote controller is transmitted to the RF transceiver 23 of the video control box 2 through the RF transceiver 丨 3, and the RF transceiver 23 transmits the processed signal to the infrared

M272316

The line transmitter 24 and the infrared transmitter 24 transmit control signals to the DVD player 3 by infrared light. The DVD player 3 operates according to the control signals and generates different audio and video signals. The audio and video signals enter the video switch 21 of the video control box 2. At the same time, the microwave transceiver 23 will send a control signal to the video switcher 2 and cut the video and audio signals transmitted by the DVD recorder 3 to the radio frequency transceiver 23. The radio frequency transceiver 23 compresses the control signal and the video and audio signals at the same time and shares the same frequency. Wide transmission, transmitted to the portable TV via RF signal 丨, the portable TV 丨 after receiving the RF signal is converted into a video signal by the RF transceiver 13 and displayed on the flat display screen, the user can watch the DVD recorder 3 playback DVD content; you can also use the VHS player remote control to control the VHS player to watch VHS movies. μ% In the foregoing case, the user can also use the remote control of the set-top box to watch the video content transmitted by the set-top box, making the portable TV 丨 the content that can be watched is abundant, and when multiple portable TVs 丨 watch various kinds in this system When watching different programs or watching the same program at the same time, using the increased quality of service (qoS) packet technology in the wireless local area network can simultaneously process the program transmission of multiple portable TVs, making each portable TV 1 will not be affected by other portable TVs and will get high picture quality and stable video quality services. # 中 的 Remote Control transmission is controlled by the service product f (Quahty of Service, Q0S) packet technology. The signal and the video signal are compressed at the same time and share the same-bandwidth transmission, and then the video control box 2 = radio frequency transceiver 23 decompresses the receipt signal and separates the processing signal and the video signal. @ This author uses the wireless receiving function of the above portable TV in a wireless M272316

With the in-house control box, users in ordinary households can receive TV programs in the room, and even in outdoor courtyards, they can also receive the wrongdoing, and the video control box can connect several different video sources.丄 Enables portable TVs to watch digital wireless transmission of DVD, VHS and set-top box video Inner Valley Reuse Quality of Service (QoS) packet technology, and enables several users to watch several video content. Therefore, this creation can not only effectively solve the problem of conventional wiring, but also
