Abstract
A video processing apparatus and method of operation are provided. The video processing apparatus includes: a video processing part which performs a video processing of a video signal and allows to display a video based on the video signal; a storing part which stores a control program related to the video processing of the video processing part; a receiving part which receives an encrypted updating program for updating the control program which is stored in the storing part; and a control part which updates the control program based on an updating program which is obtained by decrypting the encrypted updating program which is received by the receiving part by a unit of a piece of predetermined size.
Claims19
A video processing apparatus, comprising:
- a video processing part which performs video processing of a video signal and allows displaying of a video based on the video signal;
- a storing part which stores a control program for the video processing of the video processing part;
- a receiving part which receives an encrypted updating program for updating the control program which is stored in the storing part;
- and
- a control part which updates the control program based on an updating program which is obtained by decrypting the encrypted updating program which is received by the receiving part, in a unit of a piece of a predetermined size.
A control method of a video processing apparatus, the method comprising:
- decrypting an encrypted updating program which is received by a receiving part, in a unit of a piece of a predetermined size;
- and
- updating a control program which is stored in a storing part based on an updating program which is obtained by the decrypting.
An electronic apparatus, comprising:
- a functioning part which performs at least one function;
- a storing part which comprises a storing space which stores a control program for the at least one function which is performed by the functioning part;
- a receiving part which receives the control program encrypted;
- and
- a control part which stores, in the storing part, the control program which is obtained by decrypting the encrypted control program which is received by the receiving part, in a unit of plural pieces.
A control method of an electronic apparatus, the method comprising:
- decrypting an encrypted control program which is received by the receiving part in a unit of plural pieces;
- and
- storing the control program which is obtained by the decrypting in the storing part.
A method of encrypting an updating program for updating a control program of a video processing apparatus, the method comprising:
- evaluating a property value of a first piece of an updating program;
- encrypting said first piece;
- and
- selectively encrypting each of a subsequent plurality of pieces of the updating program based on property values of previously encrypted pieces.
