A deflection-distortion correcting circuit for correcting deflection-distortion of an image on a screen by modulating a source voltage for horizontal deflection is disclosed. The deflection-distortion correcting circuit includes a first correcting data generating unit for generating a first correcting data for an image display period, a second correcting data generating unit for generating a second correcting data for a vertical blanking period, deflection-distortion correcting signal generating unit for generating a correcting signal for the image display period and the vertical blanking period in accordance with the first and second correcting data, and a horizontal-deflection circuit which modulates a source voltage for horizontal deflection with the correcting signal. The second correcting data generating unit generates the second correcting data such that the correcting signal has a value, at a start of a vertical blanking period, which is equal to a value of the correcting signal at an end of an image display period, and that the correcting signal varies monotonically during the whole period of the vertical blanking period and reaches, at an end of the vertical blanking period, a value at a start of the image display period.

In order to provide various service types to the users in a case of supplying the contents constituted from multiple resources via broadcast, the following apparatuses are provided. An encryption apparatus (100) encrypts the resources-to-be-encrypted of the contents, stores the encrypted resources in the packets and transmits the packets via broadcast. An encryption portion which encrypts each of contents constituted from multiple resources by applying a corresponding encryption key and generates and transmits packets that store encrypted data or non-encrypted data of the resources. A licensing apparatus (2) providing a license via communication network while the license includes both a license identifier which indicates a broadcast range in which the license is effective and the decryption key provided in correspondence with each of resources-to-be-encrypted. A decryption apparatus (300), by using the corresponding decryption key included in the license received via communications lines, decrypts the encrypted data of the packets received via broadcast.

A first PLL circuit (100) receives a flyback pulse (VFB) as a reference signal and outputs a clock signal (CLK1), and a delay circuit (200) outputs a flyback delay signal (VFBD) having a predetermined delay time corresponding to the amount of horizontal movement on a screen. A second PLL circuit (300) receives a horizontal synchronizing signal (VHSYNC) and the flyback delay signal (VFBD) as a reference signal and a compared signal, respectively, and generates a horizontal drive pulse (VHD). A deflection yoke (12) receives the horizontal drive pulse (VHD) and generates a flyback pulse, and a step-down transformer circuit (16) outputs the flyback pulse (VFB) whose voltage is lowered. With this constitution, it becomes possible to generate a stable horizontal drive pulse which causes no jitter on the screen when a PIN balance correction, a KEY balance correction and a horizontal position adjustment of a CRT are performed by digital processing.
