System and method for transcoding signal content
First Claim
1. A method comprising:
- receiving in a set-top-box a signal having a conditionally accessible content and encoded based on a first audio/video encoding scheme;
conditionally accessing the content of the received signal in the set-top-box based on predetermined access criteria;
transmitting the conditionally accessed content to a decoder within the set-top box and maintaining the conditionally accessed content entirely within the set-top box if a logic within the set-top box determines that the first audio/video encoding scheme is compatible to a second audio/video encoding scheme supported by the decoder within the set-top-box;
transmitting the conditionally accessed content to a device external to the set-top-box in lieu of transmitting the conditionally accessed content to the decoder after the logic within the set-top-box determines that the first audio/video encoding scheme is incompatible with the second audio/video encoding scheme supported by the decoder within the set-top-box;
transcoding the conditionally accessed content by the device from the first audio/video encoding scheme to the second audio/video encoding scheme if the conditionally accessed content is transmitted to the device external to the set-top box; and
providing the transcoded content back to the set-top-box if the conditionally accessed content is transmitted to the device external to the set-top box.

Abstract
In one embodiment, a method and system for receiving in a set-top-box a signal including a conditionally accessible content and encoded based on a first audio/video encoding standard (AVES); conditionally accessing the content of the signal in set-top-box based on predetermined access criteria; transmitting the content to a device external to the set-top-box; transcoding the content by the device from the first audio/video encoding standard to a second AVES; and providing the transcoded content to the set-top-box. In another embodiment, an apparatus including a set-top-box including a conditional accessing logic to access the content of a signal; and a set-top-box housing including an opening to allow interfacing between set-top-box and a transcoder system, the transcoder system to receive the content from the set-top-box via the opening, to transcode the content from a first AVES to a second AVES, and to provide the transcoded content to set-top-box via the opening.

9. A system comprising:
-
a set-top box to receive a signal having a conditionally accessible content and encoded based on a first audio/video encoding scheme, the set-top box including a decoder and a conditional accessing logic to conditionally access the content of the received signal based on predetermined access criteria, the conditional accessing logic to maintain the conditionally accessible content within the set-top box and to route the conditionally accessible content to the decoder if the first audio/video encoding scheme is compatible to a second audio/video encoding scheme supported by the decoder; and a transcoder system to receive the conditionally accessed content from the set-top box only when the first audio/video encoding scheme is incompatible with the second audio/video encoding scheme supported by the decoder, to transcode the conditionally accessed content from the first audio/video encoding scheme to a second audio/video encoding scheme, and to provide the transcoded signal to the set-top box. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. An apparatus comprising:
-
a decoder; a demultiplexer having a first output coupled to the decoder; conditional access logic in communication with an input of the demultiplexer, the conditional access logic to conditionally access content of a received signal based on predetermined access criteria, the received signal including data encoded according to a first audio/video encoding scheme, the conditional accessing logic further determining if the first audio/video encoding scheme is incompatible with a second audio/video encoding scheme supported by the decoder; and a housing to contain the decoder, the demultiplexer and the conditional access logic, the housing including an opening adapted to receive a transcoder system that, in communication with the demultiplexer, (i) receives the content from the conditional access logic only after the conditional accessing logic determines that the first audio/video encoding scheme is incompatible with the second audio/video encoding scheme supported by the decoder, (ii) transcodes the content from a first audio/video encoding scheme to a second audio/video encoding scheme, and (iii) returns the content formatted in the second audio/video encoding scheme via the opening for subsequent rendering and display, wherein the decoder to receive the content from the conditional access logic via the demultiplexer in lieu of routing the content to the transcoder system when the first audio/video encoding scheme is compatible with the second audio/video encoding scheme supported by the decoder. - View Dependent Claims (20)
