Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] In the embodiment of the present invention, the storage unit receives the transport stream to be smoothed according to the received first write command, sends the transport stream according to the received read command, and the cache unit receives the transport stream sent by the storage unit according to the received second write command. The transport stream finally outputs the transport stream stored in the cache unit, which realizes the smooth processing of the burst transport stream at a large bit rate, with high speed and low cost.

Abstract

The invention is applicable to the field of multimedia communication, and provides a method and a system for smoothly processing transmission stream and front-end equipment of a digital television. The system comprises a storage unit, a buffer unit, an access control unit and an output control unit, wherein the storage unit is used for receiving a first write instruction, receiving the transmission stream to be smoothly processed according to the first write instruction, receiving a read instruction, and sending the transmission stream according to the read instruction; the buffer unit is usedfor receiving a second write instruction, and receiving the transmission stream sent by the storage unit according to the second write instruction; the access control unit is used for sending the first write instruction to the storage unit according to the detected transmission stream to be smoothly processed, sending the read instruction to the storage unit according to a storage space state ofthe buffer unit, and simultaneously sending the second write instruction to the buffer unit; and the output control unit is used for selecting output transmission stream or output space packets according to the length of the transmission stream in the buffer unit. The method and the system achieve smooth processing of burst transmission stream at large code rate, and have high speed and low cost.

Description

technical field [0001] The invention belongs to the field of multimedia communication, and in particular relates to a method, system and digital TV front-end equipment for smooth processing of transport streams. Background technique [0002] Motion Picture Experts Group (MPEG-2) is an international standard for digital television, which defines the data structure used for video compression data, audio compression data, control data and private data consumption, including program stream (Programme Stream, PS) and Transport Stream (TransportStream, TS). Among them, the transport stream is a data structure with a fixed packet length, taking frames as the unit, and is mainly used for the transmission of compressed code streams. [0003] With the further maturity of digital TV technology, in terms of video servers, it is necessary to handle a large number of concurrent tasks and high bit rate burst stream transmission. Burst data transmission is shown in Figure 1(a), that is, t...
