Equipment for realizing content filtering of simulating multimedia broadcasting

Abstract

The invention provides an equipment for realizing content filtering of simulating multimedia broadcasting, comprising a multimedia signal input circuit, a tuning circuit, a signal storage delay circuit, wherein the multimedia signal input circuit receives digital multimedia broadcasting signals; the output of the multimedia signal input circuit is connected with the tuning circuit; the output of the tuning circuit is connected with the signal storage delay circuit; the signal storage delay circuit digitalizes the multimedia input signals output by the tuning circuit into multimedia data and stores the multimedia data in a storage; and when reaching a certain capacity, the stored multimedia data is read and is synthesized into multimedia signals which are then output, and the multimedia input signals are digitalized into multimedia data continuously in the output process of multimedia signals and are stored in the storage. The equipment realizes that a receiver filters unneeded contentaccording to own preference under the demand of minimum delay time and minimum storage capacity so as to improve receiving experience of the receiver.

Description

technical field [0001] The invention relates to a device for filtering simulated multimedia broadcasting content, in particular to a device for filtering multimedia broadcasting content by adopting methods of storing delayed playing and simultaneously storing and playing simultaneously. Background technique [0002] With the development of electronic technology and information technology, broadcast signals have developed from the original analog wireless broadcast signals to analog cable broadcast signals, analog satellite broadcast signals, digital wireless broadcast signals, digital cable broadcast signals, and digital satellite broadcast signals. The broadcast content includes multimedia broadcast content composed of audio, video, data and other information, so that people can receive multimedia broadcast content through multiple channels. [0003] On the other hand, for their own development, broadcast operators usually insert advertising information or opening and clos...

Problems solved by technology

The problems existing in the existing storage and playback equipment are: 1) because the storage and playback cannot work at the same time, the program being played will be missed during playback; 2) when the program is stored, it is necessary to record all the programs including the advertisement information in order to watch all the programs The content requires a lot of storage capacity, and its storage capacity is the sum of the storage capacity required for non-program time and the storage capacity required for program time, which increases the cost of storage and playback equipment, and the delay time for watching programs is too long, that is, when the delay time broadcast time of the entire program
