Problems solved by technology

Therefore, if a receiving device of a particular transmission standard is used in an environment where a broadcast transmission signal is broadcast using a different transmission standard (i.e., a different region of the world), the receiving device cannot process the data in the broadcast transmission signal

Embodiment Construction

[0015] Disclosed below is a multi-standard receiving device capable of receiving multiple broadcast transmissions from different broadcasters, where the multiple transport streams use different transmission standards. Processing the received broadcast transmission enables processing of metadata related to the particular transmission standard used by the particular broadcast transmission. A metadata item is generated and used as part of an interactive electronic program guide (EPG) user interface (UI) to represent information contained in the received metadata. This EPG is displayed to the user.

[0016] figure 1 An example delivery system 100 is shown. System 100 includes a plurality of content providers or broadcasters 105-1, 105-2, and 105-3. Use television transmissions, broadcast transmission signals, and transmission standards as examples. However, it must be taken into account that other forms of transmission may also be used such as data, wireless and non-television...

Abstract

A multi-standard receiving device processes broadcast transmission signals that use multiple differing transmission standards. Processing entails conversion of the transmission standard's protocol standard into a normalized transport agnostic representation in order to allow consistent manipulation of a broadcast transmission signal's contents regardless of the transmission standard.

Description

technical field [0001] The invention relates to a multi-transmission receiving device for receiving broadcast transmissions using different transmission standards and converting metadata in the broadcast transmissions into formatted electronic program guide items. Background technique [0002] Broadcast transmissions contain audio data, video data, and metadata which can be in-band or out-of-band. Metadata describes the audio and video content and some additional information provided by the audio and video data. Additional metadata information may include information about when a program was broadcast, where viewers can tune in to the program broadcast (i.e., tuner frequency or channel), which content provider the program originated from (e.g., broadcaster, TV network) and a description of the show. [0003] Broadcast transmission signals utilize one of several transmission standards. A transmission standard defines how to broadcast a broadcast transmission signal, and fu...
