Embodiment Construction

[0027] Specific embodiments of the present invention are described below:

[0028] The method provided by the present invention performs corresponding processing on the video before the start time of the first broadcast of the video, such as figure 1 As shown, before the first broadcast point, the video file is divided into n video fragments in the order of front and back; each video fragment is selected for encryption with a random independent key, and the encrypted n video fragments are encrypted according to the order of front and back. Text information flow, and n keys form a key information flow in sequence; upload the ciphertext information flow and key information flow to the publishing server; the publishing server publishes the ciphertext information flow for the user terminal to download locally.

[0029] After the start time of the video premiere, perform corresponding processing on the video, such as figure 2 As shown, after the first broadcast point, the publish...

Abstract

The invention relates to a network video premiering method. The method comprises the content of dividing a video file into n video segments in sequence before a premiering time point; encrypting each video segment by selecting a random independent key, forming ciphertext information streams in sequence according to the encrypted n video fragments, and forming key information streams in sequence according to the n keys; uploading the ciphertext information streams and the key information streams to a release server; releasing the ciphertext information streams by the release server, wherein the ciphertext information streams are used for a user terminal to download to the local; releasing one key each time in sequence by the release server after the premiering time point, wherein the key is used for the user terminal to download to the local; decrypting the corresponding encrypted video fragments in the downloaded ciphertext information streams by the user terminal through utilization of the keys, thereby obtaining the video segments before encryption; and after the user terminal caches to obtain the former m video segments, starting integrating the video segments for playing.

Description

technical field [0001] The present invention relates to the technical field of streaming media, and more specifically, to a network video premiere method and system. Background technique [0002] With the development of Internet technology, watching online video has become one of the main ways of people's leisure and entertainment. At the same time, people have higher and higher requirements for the clarity and fluency of online video. Current network video mainly adopts technologies such as P2P, streaming media and buffering to improve the clarity and smoothness of video. However, due to the limitation of network bandwidth and the influence of network delay, the user experience is still difficult to match that of cable TV. [0003] At present, many TV dramas or movies are premiered synchronously through the Internet and cable TV. For commercial reasons, network users cannot download or watch TV dramas or movies before the premiere point; after the premiere point, network u...
