Embodiment Construction

[0021] The radio and television service data processing device in each embodiment of the present invention may be a head-end device for receiving and processing broadcast and television service data packets, and the head-end device sends the broadcast and television service data packets to multiple Terminal Equipment. The terminal equipment can be used as a functional module in the set-top box and built in the set-top box. After the radio and television service data processing device receives the broadcast and television service data packet, it does not use DVB technology to process the broadcast and television service data packet, but uses the broadcast and television service data processing method provided by the embodiment of the present invention to process.

[0022] Compared with the two-way data signal, the radio and television service data packet has the following characteristics. The transmission direction is one-way transmission, and it is sent to multiple terminal de...

Abstract

The invention provides a radio and television service data processing method and a device. The radio and television service data processing method comprises a step of calculating the number of radio and television service data packets which can be borne by each broadcast frame according to the frame length of each broadcast frame and the packet length of each received radio and television business packet, a step of packing radio and television service packets of the number in a broadcast frame if the judged number is a whole number, and a step of adopting a concatenated code to carry out coding to the broadcast frames and obtaining broadcast frames, wherein channel coding is carried out to the broadcast frames. Through the fact that improvement of the an EOC technology is carried out, the radio and television service data processing method is adopted to process the radio and television service packets, larger bandwidth and higher transmission rate can be used for transmitting the radio and television service packets, and lower probability of errors and higher transmission reliability further can be guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to cable television technology and communication technology, and in particular to a method and device for processing broadcast and television service data. Background technique [0002] The traditional cable TV network is a point-to-multipoint unidirectional broadcast network, which uses frequency division multiple access to transmit signals without congestion control, and is used to carry unidirectional broadcast services. In the cable TV network, the front-end computer room converts the input signal into a high-frequency TV signal that meets the transmission requirements, synthesizes multiple TV signals into one signal, and feeds it to the hybrid fiber-optic coaxial cable composed of the trunk transmission network and the user distribution network ( Hybrid Fiber-Coax, HFC) network, and finally sent to the set-top box as the user terminal. [0003] The cable TV network uses Quadrature Amplitude Modulation (...
