Video and audio streaming method of multi-angle interactive TV

Abstract

A video and audio streaming method of a multi-angle interactive TV can transmit different-angle videos and audios according to user' needs. By using an image cutting method, the method simultaneously synchronizes a plurality of cameras to images photographed from different angle, cuts each group of consecutive images into small videos, and then transmits the consecutive small videos with specific angle to clients through a streaming network transmission mode in accordance with needs of watching and angle switching of the clients. The clients receive videos through a hardware player and select watching angle. The method can provide interactions between the clients and the TV and the autonomy to choose watching angles without additional network load, so as to improve user' watching quality and abundance.

Description

technical field [0001] The present invention relates to an audio-visual streaming method for a multi-view interactive TV. According to the user's different switching angle requirements, the correct angle and time point are converted in real time, and the corresponding series of small The videos are combined into a user-specific channel, which is transmitted to the client for viewing through the streaming network transmission method. Background technique [0002] Before this case, there was no exact technology to achieve this effect. The channels provided by the current Internet TV (IPTV) are all previously recorded or operated by professionals (for example: real-time football game broadcast, concert, etc.) Users can only use the channel switching function to choose a channel that is more suitable for them to watch the filmed film, but cannot change the content of the channel. With the advancement of technology and the advent of the interactive era, channel switching alone w...

Problems solved by technology

[0002] Before this case, there was no exact technology to achieve this effect. The channels provided by the current Internet TV (IPTV) are all previously recorded or operated by professionals (for example: real-time football game broadcast, concert, etc.) For the produced videos, users can only use the channel switching function to choose a channel that is more suitable for them to watch, but cannot change the content of the channel

With the advancement of technology and the advent of the interactive era, channel switching alone will not be able to meet the diverse needs of users

[0003] In order to meet the needs of users for innovation and change, the function of interacting with users will bring different feelings to users. To achieve the effect of multi-view interactive TV, the traditional method is to treat each angle as a different channel. It is for users to switch, but in this way, the video server needs to transmit channel content from various angles for users to choose at the same time, resulting in doubled network load and it will be difficult for users to watch pictures from different angles at the same time, and in essence, it still provides the function of channel switching instead of actually interacting with the user

[0004] It can be seen that the above-mentioned traditional method still has many deficiencies, it is not a good design, and needs to be improved urgently
