Benefits of technology

[0008]Another object of the present invention is to provide a cable broadcast program receiver and a diagnostic method of the cable broadcast program receiver that enables a user of the cable broadcast program receiver to directly diagnose status of the DiiVA interface of the cable broadcast program receiver or that enables a head-end to remotely diagnose status of the DiiVA interface of the cable broadcast program receiver.

Problems solved by technology

In a case in which a conventional cable broadcast program receiver has a DiiVA interface, however, a method of diagnosing the DiiVA interface of the cable broadcast program receiver is not provided.
Although the DiiVA interface has trouble, therefore, it is not possible for a user or a head-end to find or solve the trouble of the DiiVA interface.

Embodiment Construction

[0028]Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0029]A cable broadcast system broadly includes a cable broadcast station or cable TV station) and a cable broadcast program receiver (or digital cable TV receiver). Herein, the cable broadcast station is a transmitting and receiving end transmitting cable broadcast programs, and the cable broadcast program receiver receives the transmitted cable broadcast program. The cable broadcast station may be referred to an SO head-end or an MSO head-end. The SO refers to a System. Operator (SO), which is a Korean Cable System Operator (i.e., the Local Cable TV System Operator), and the MSO refers to a Multiple System Operator (MSO), which is a group of system operators.

[0030]Moreover, the cable broadcast program rece...

Abstract

The present invention relates to a cable broadcast program receiver and a diagnostic method of the cable broadcast program receiver. In an aspect of the present invention, a diagnostic method of a cable broadcast program receiver may include transmitting, at a cablecard, a diagnostic request containing diagnostic information regarding DiiVA connection status to a host according to a protocol of an interface between the cablecard and the host; and receiving, at the host, the diagnostic request and transmitting diagnostic confirmation information containing a diagnostic status report regarding the DiiVA connection status to the cablecard according to the protocol of the interface between the cablecard and the host in response to the diagnostic request.

Description

[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 549,754, filed on Oct. 21, 2011, which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a cable broadcast program receiver and a diagnostic method of the cable broadcast program receiver.[0004]2. Discussion of the Related Art[0005]A high-speed interface standard used in audio / video devices, i.e. a digital interactive interface for video & audio (DiiVA), has a network function operating at high speed and a level equivalent to Ethernet. DiiVA is a next-generation display interface that is capable of freely achieving connection among a personal computer (PC), a digital TV, and all display devices (Blulay Player, Set-top box, etc.) using one of the latest connectors. DiiVA may completely substitute the existing standard to achieve connection between a TV and a digital device in a high definition multimedia interface (HDMI) m...
