摘要:
A method for processing a digital audio broadcast signal in a radio receiver includes: receiving a digital audio broadcast signal; demodulating the digital audio broadcast signal to produce an analog audio stream and a digital audio stream; determining a digital signal quality value for the digital audio stream; blending an output of the radio receiver from the analog audio stream to the digital audio stream when the digital signal quality value exceeds an adaptive analog-to-digital threshold value; and blending the output of the radio receiver from the digital audio stream to the analog audio stream when the digital signal quality value falls below an adaptive digital-to-analog threshold value, wherein the adaptive digital-to-analog threshold value is lower than the adaptive analog-to-digital threshold value.

本発明は、放送されたコンテンツデータの欠損データを補完する際において、通信網のトラフィックを極力軽減することができる放送補完データ伝送装置および放送補完データ伝送方法、ならびに放送システムを提供することを目的とする。 受信装置から時刻情報を含んだ欠損データの再送要求である、"GET HTTP/1.1 If Unmodified Since 時刻情報"を受信すると、当該再送要求に含まれる時刻情報に基づいて、HTTP応答部は、欠損データを含んだコンテンツの再放送の有無を判断する。そして、HTTP応答部により再放送があると判断されると、レスポンスとして、エラー通知の一つである"412Precondition Failed"を受信装置に送信して、通信網を介したコンテンツの送信を行わない。
摘要:
The present invention relates to a system and method for providing content using a mute period of a digital TV. The system of the present invention comprises: a digital broadcast receiving system which displays pre-selected content using a display panel of the digital TV during a mute period provided upon changing a channel; and a content management server which provides the digital broadcast receiving system with content, whereby improving user convenience and making profits.
摘要:
In general, this disclosure relates to techniques for switching between media broadcast streams having varying levels of quality. In one example method, a processing pipeline of a communication device processes a first broadcast stream representing a first version of media content. The processing pipeline includes quality checkpoints at which broadcast stream quality may be determined, and receives a second, different broadcast stream that is broadcasted at another data rate. The second broadcast stream represents a second version of the media content of different media quality. The processing pipeline measures a quality of the first broadcast stream and a quality of the second broadcast stream at one or more of the quality checkpoints, and switches the processing from the first broadcast stream to the second broadcast stream if the quality of the second broadcast stream exceeds a defined threshold at one or more of the quality checkpoints.
摘要:
An audio dynamics processor or processing method that uses a reset mechanism or process in order to adapt quickly to content changes in the audio signal. A reset signal may be generated by analyzing the audio signal itself or the reset may be triggered from an external event such as a channel change on a television set or an input selection change on an audio/visual receiver. In the case of an external trigger, one or more indicators of the state of the dynamics processor for a current audio source may be saved and associated with that audio source before switching to a new audio source. Then, if the system switches back to the first audio source, the dynamics processor may be reset to the state previously stored or an approximation thereof.

This invention relates to a user interface to be implemented in a device, wherein the device comprises a tuner and a receiver for receiving broadcast signals from broadcast stations. The user interface uses semantic information associated with the received broadcast signals for sorting the received broadcast stations based on sorting criteria and displays the sorted broadcast stations on a display.

摘要:
A memory control system (130, 200) for a network (10) that broadcasts to multiple terminals (16) content data including music, video and the like, and also including commercial advertisements. A memory (208) in the terminal unit (16) stores content data that is played upon a loss of signal from the broadcast network (10). The memory (208) also stores commercial advertisements for playback from the terminal memory (208) according to schedule control instructions, which are also stored in a memory (210) at the terminal unit (16). Writing of content to a memory and reading content from the memory may be executed concurrently by interleaving. A microprocessor (206) arbitrates use of input, output and memory buffers (202, 204, 208) such that reading content from memory provides content output maintaining uninterrupted real time play even when new content data is being stored concurrently. Content data memory addresses are stored in sector tables that are further arranged in File Allocation Tables in a second memory (210).
