Techniques for rapidly delivering broadcasted live content are described. In an example, a transaction request to create placeholder non-fungible tokens (NFTs) in a token repository (106) is sent, where NFTs represent unique digital items. In response to the transaction request, an address allocated to a placeholder NFT from the plurality of placeholder NFTs in the token repository (106) is received. A notification indicating availability of the piece of live content is then transmitted to a user device (102), where the notification is indicative of the address allocated to the placeholder NFT in the token repository (106). In the meantime, a unique representation of the piece of live content is generated and populated on the token repository (106).

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Test code is embedded in ATSC 3.0 content to determine whether a receiver can render the content. The results are reported back to the broadcaster, which can alter content or perform other modifications based on aggregated rendering statistics.

This application provides an image model file transmission method and computing device. The method includes: receiving an image model file of a first online streamer that is sent by a first client; obtaining a target key, and encrypting the image model file based on the target key to obtain an encrypted image model file; in response to determining that an interaction request for the first online streamer and a second online streamer is received, sending the encrypted image model file to a second client based on an online streamer identifier of the second online streamer that is carried in the interaction request; and in response to determining that a decryption request sent by the second client is received, sending the target key to the second client, where the target key is used by the second client to decrypt the encrypted image model file to obtain the image model file.

This application provides an online streamer image picture transmission method and computing device in live interaction. The method applied to a server, the method includes: receiving an online streamer image picture sent by a first online streamer end, and obtaining a target obfuscation key; performing encryption processing on the online streamer image picture based on the target obfuscation key and picture information of the online streamer image picture, to obtain an encrypted online streamer image picture; and in response to determining that a live interaction request for the first online streamer end and a second online streamer end is received, sending the encrypted online streamer image picture and the target obfuscation key to the second online streamer end.

A method and apparatus for secure multimedia transfer provides an encrypted data transfer system that makes transferring multimedia content from a client to any incompatible system or to a system outside the location of the client very difficult.

A secure media player system for communicating media content information from an encoder to a decoder is provided. The encoder is operable to: process and encode media content information into section(s) of encoded data. The section(s) of encoded data include parameters which enable the media content information to be regenerated from the section(s) of encoded data; encrypt the section(s) of encoded data to generate corresponding encrypted section(s) of encoded data; and communicate the unencrypted and/or encrypted section(s) of encoded data to the decoder for the decoder to process the unencrypted and/or encrypted section(s) of encoded data to render the media content information to one or more users, wherein the secure media player system does not store or allow storage, namely prevents storage. of the section(s) of encoded data in a decrypted form to unprotected memory.

A content viewing method uses a viewing system including a content distribution server distributing contents, a mobile information terminal, and a viewing device reproducing a content. The mobile information terminal transmits user identification information and a user password to the content distribution server. The content distribution server authenticates the mobile information terminal based on the user identification information and the user password. The mobile information terminal transmits an account issue request requesting an account for reproducing a desired content to the content distribution server. The content distribution server issues the account based on the account issue request and transmits the account to the mobile information terminal. The mobile information terminal stores the account. The mobile information terminal transmits the account by short-range wireless communication. The viewing device stores the account received by short-range wireless communication. The viewing device reproduces the desired content using the stored account.

Techniques are provided for dynamically creating index files for streaming media based on a determined chunking strategy. The chunking strategy can be determined using historical data of any of a variety of factors, such as Quality of Service (QoS) information. By using historical data in this manner, index files can be generated using chunking strategies that can improve these factors over time.

The present invention allows the combination and adaptation of a broadcast data reception system with a Conditional Access System which may be embedded in the receiving device, such as a television, or can be provided as a module which is connected to the receiving device and which allows service provider controlled, typically cloud based, interactivity via the same CAS with different Multi Channel video programming distributors (MVPD) service providers.

Techniques and a system are provided for protecting content (or media item) streamed over a network from unauthorized access. As an example, the streaming protection system generates statistics when a client requests a media item. The statistic may be generated based on various factors. The media item is divided into different portions, each portion requiring a different key to decrypt the portion so that it may be viewed by a user. Based on the generated statistic, the streaming protection system determines whether or not to allow the client access to the decryption key for a portion of the media item.
