Abstract
A system and method of wireless display, including a transmitter processing a first encrypted content into a second encrypted content without decoding, and transferring the second encrypted content over a wireless display connection to a receiver.
Claims25
A method of wireless display, comprising:
- negotiating a wireless connection between a transmitter and a receiver to wirelessly couple the transmitter and the receiver;
- establishing a wireless display connection between the transmitter and the receiver;
- receiving at the transmitter a first encrypted content;
- processing, via the transmitter, the first encrypted content into a second encrypted content without decoding;
- and
- transferring, via the wireless display connection, the second encrypted content from the transmitter to the receiver.
3 more elements
A method of wireless display, comprising:
- establishing a wireless display connection between a transmitter and a receiver;
- and
- performing by the transmitter:
- dividing a first encrypted content into a first encrypted video and a first encrypted audio;
- decrypting the first encrypted video to give decrypted video, and decrypting the first encrypted audio to give decrypted audio;
- encrypting the decrypted video to give a second encrypted video, and encrypting the decrypted audio to give a second encrypted audio;
- combining the second encrypted video and the second encrypted audio into a second encrypted content;
- and
- transferring, via the wireless display connection, the second encrypted content to the receiver.
6 more elements
A transmitter configured for wireless display, comprising:
- a processor;
- and
- memory storing instructions that when executed by the processor cause the transmitter to:
- receive a first encrypted content and divide the first encrypted content into a first encrypted video and a first encrypted audio;
- decrypt the first encrypted video to give decrypted video, and decrypt the first encrypted audio to give decrypted audio;
- encrypt the decrypted video to give a second encrypted video without decoding the decrypted video, and encrypt the decrypted audio to give a second encrypted audio without decoding the decrypted audio;
- combine the second encrypted video and the second encrypted audio into a second encrypted content;
- and
- transfer the second encrypted content over a wireless display service connection to a receiver.
6 more elements
A tangible, non-transitory, computer-readable medium comprising instructions that, when executed by a processor of a computing device, cause the computing device to:
- receive a first encrypted content and divide the first encrypted content into a first encrypted video and a first encrypted audio;
- decrypt the first encrypted video to give decrypted video, and decrypt the first encrypted audio to give decrypted audio;
- encrypt the decrypted video to give a second encrypted video without decoding the decrypted video, and encrypt the decrypted audio to give a second encrypted audio without decoding the decrypted audio;
- combine the second encrypted video and the second encrypted audio into a second encrypted content;
- and
- transfer, via a wireless display service connection, the second encrypted content to a receiver.
