Abstract: The disclosure is related to a real-time analysis of social network service (SNS) data associated with a multimedia content service. Particularly, SNS users may be classified into active SNS users and non-active SNS users, based on an SNS activity amount. SNS data collection/analysis periods may be differently determined according to SNS user types. Furthermore, a statistical analysis result of the SNS data may be directly or indirectly provided to one or more user equipment such that the SNS data analysis result can be displayed along with a corresponding multimedia content.

Abstract: A shadow mask for a cathode ray tube includes a beam-guide member having a substantially rectangular shape with short opposite sides in a vertical axis direction and long opposite sides in a horizontal axis direction. The beam-guide member is provided with a plurality of apertures and tie bars interconnecting the neighboring apertures in the vertical and horizontal axis directions. Each aperture has an opening portion and a tapering portion surrounding the opening portion. A skirt with a bent end portion is extended from the beam-guide member. The beam-guide member is structured such that the relationship of a length A of the tie bar in the vertical axis direction to a pitch Pv between the neighboring apertures in the vertical axis direction satisfies the following condition: 0.05≦APv≦0.15.

Abstract: A cathode ray tube for multimedia includes a shadow mask having a plurality of beam-guide apertures. Each of the beam-guide apertures has a stripe shape and the ratio of a horizontal length of an effective screen to a horizontal pitch of the beam-guide apertures in the center of the shadow mask is in the range of 1:8.81×10−4 to 1:1.23×10−3. The ratio of the horizontal pitch of the beam-guide apertures in the center of the shadow mask to the thickness of the shadow mask is in the range of 1:0.25 to 1:0.56.
