The present invention describes and claims a new system and technique or method for decoupling the interpretation of broadcast content information from the display of this information. The information may exist in any of the available types, such as audio, video, or data. In addition, the information may be received in any form, such as streaming or non-streaming, combinations of the two, or even parts thereof. The decoupling and encapsulating of the broadcast content information is accomplished using a content proxy. All content information in the content proxy is accessed via an Application Program Interface. The content proxy employs a hierarchical Document Object Model (DOM) that contains Program and System Information Protocol (“PSIP”) data, that has been converted to an eXtendible Markup Language format using a conversion algorithm, broadcast content data, as well as content data or information about all of the hardware, software, and appliances connected within the networked environment. The proxy concept is applicable to the design and implementation of a Digital TV broadcast rendering device within a Digital TV Application Software Environment framework.

A splicing system includes a splicer for seamlessly splicing togther digitally encoded data streams. In a preferred embodiment, the splicer preferably parses successive splice buffers of data stream data for a splice-out point and a splice-in point, closing an initial group of pictures GOP if needed. The preferred splicer further finds a new data stream real-time program clock reference PCR value for aligning new data stream decode / presentation, and aligns the new data stream start time. Concurrently, the splicer preferably uses a frame table to detect overflow and corrects such overflow by adding null packets, thereby delaying portions of data stream data. The splicer also preferably restores data stream encoding by deleting null packets, and thereby accelerating a portion of data stream data. In a further preferred embodiment, the splicer preferably uses a bit-clock schedule offset to delay or accelerate portions of data stream data.

Disclosed is a system and method for correcting the separation of synchronized video signals resulting from transmission over wires of different lengths. Preferably, circuitry is used to inject a signal pulse along the red, green, and blue video signal transmission lines through a selectable delay circuit to a skew compensation circuit located at a user workstation. The skew compensation circuit sums the amplitudes of the received signal pulses and compares the result to a reference amplitude. This is repeated for each possible delay combination of the selectable delay circuits.

This delay combination is implemented in the selectable delay circuits and normal video transmission is allowed to resume such that the red, green, and blue components of the video signal arrive at the video monitor at approximately the same time.
