Embodiment Construction

[0123]The broadcast type NVOD program making, sending and receiving device involved in the present invention is used in China's one-way digital cable broadcasting television network to carry out NVOD business. Now the DVB standard is adopted in China's one-way digital cable broadcasting television network, and program compression generally uses MPEG2 standard.

[0124] Refer below figure 1 , 2 and 3 illustrate a block diagram of an apparatus for producing, transmitting and receiving broadcast NVOD programs according to an embodiment of the present invention. Video and audio signals are sent from video and audio program playback equipment 11 such as tape machines, DV cameras, VCD / DVD players, etc. through S terminals, CVBS (composite signals), YUV (component signals), SDI (digital signals) or XLR connectors (analog audio or digital audio) and the like output to the program collection workstation 12. In the program acquisition workstation 12, the video and audio data acquisit...

Abstract

A device and method for producing, sending and receiving broadcast quasi-video-on-demand programs, mainly comprising: video and audio program playback and recording equipment; program collection and production workstations; storage equipment; broadcast servers; code stream re-multiplexers and channel modulation Equipment; a terminal receiver that receives programs over a network. Broadcast NVOD program technology from the broadcast server to the terminal through any remote communication network, including program production, transmission, reception and display. The program production workstation divides, multiplexes and packages the compressed and coded program content, and at the same time adds a specific code stream identifier to be broadcast and sent by the broadcast server; the terminal receiving device selectively buffers the program content information according to the code stream identifier, And the received program content information is reassembled, decompressed and displayed. There is no limit to the number of receiving ends, and the network provides a connection with a certain unidirectional transmission bandwidth, so that users can watch a program from the beginning in a very short time.

Description

technical field [0001] The invention relates to a device and method for making, sending and receiving broadcast-style near-video-on-demand (NVOD) programs. Background technique [0002] Video on Demand (VOD) is a very valuable service, and it is also one of the hot spots in the development of digital TV in recent years. In a broad sense, the VOD service system should be able to process multimedia information including still images, high-quality video and audio programs, and computer software, but at present it is mainly used to process movies and TV programs. The VOD service system is generally realized by two-way network. The client obtains the program list available for on-demand from the VOD play center, and submits an operation request to the play center. Users generally watch through a TV or PC monitor. Because the amount of data required for video and audio information is very large, and the processing power of the VOD playback server and the bandwidth resources of t...
