Abstract

The invention discloses a TV program transmission method based on the HTTP real-time streaming media protocol, comprising: preparing a slice cache with a fixed data capacity; and sending the index list number of the slice cache to the client according to the index file request sent by the client ; When there is a complete image group in the tile cache, send the image group to the client. The invention also discloses a TV program transmission device based on the HTTP real-time streaming media protocol. By adopting the invention, the time delay of transmitting live TV programs through the HLS protocol can be reduced, thereby improving user experience.

Description

technical field [0001] The present invention relates to the communication field (technique), in particular to a method and device for transmitting television programs based on the HTTP real-time streaming media protocol. Background technique [0002] With the development of computer and network technology, smart set-top boxes gradually replace traditional digital set-top boxes and become the control and service center of home multimedia. At present, a common solution is that smart set-top boxes serve as a home sharing center, allowing users to watch TV programs through smart terminals. So you don't have to be limited to watching programs in front of the TV. Smart set-top boxes and smart terminals can transmit streaming media through the HLS protocol. HLS (HTTP Living Streaming) is an HTTP-based real-time streaming media transmission protocol, which can divide the entire media stream into small HTTP-based program data streams for transmission. However, the transmission of li...
