Abstract:
(EN) The purposes of the present invention are: to enable a swift return to a normal state from a link loss state; and to inhibit flickering of a screen due to the effect of noise or the like. A CPU 28 implements control such that the output, to a source device 10, of a hot plug detection signal HPD indicating that link loss has occurred after a link was initially established, becomes invalid. A DPRX 22 performs the function of detecting the occurrence of link loss during the reception of a data stream continuously transmitted from the source device 10. If the occurrence of link loss is detected, the DPRX 22 performs the function of extracting a clock signal embedded in the data stream. If the occurrence of link loss is detected, the DPRX 22 performs the function of detecting a blanking start symbol embedded in the data stream. An RT register 32 stores signal reception conditions when the link is established. The extracted clock signal, the signal reception conditions, and the detected blanking start signal are used to re-establish the link.
(FR) La présente invention vise à permettre un retour rapide à un état normal depuis un état de perte de liaison ; et à empêcher le papillotement d'un écran sous l'effet du bruit ou analogue. Une UC (28) exécute une commande de sorte que la sortie, vers un dispositif source (10), d'un HPD de signal de détection de branchement à chaud HPD indiquant l'apparition d'une perte de liaison après l'établissement initial d'une liaison, devient invalide. Un DPRX (22) réalise la fonction de détection de l'apparition d'une perte de liaison pendant la réception d'un flux de données transmis en continu à partir du dispositif source (10). Si l'occurrence d'une perte de liaison est détectée, le DPRX (22) réalise la fonction d'extraction d'un signal d'horloge incorporé dans le flux de données. Si l'occurrence d'une perte de liaison est détectée, le DPRX (22) réalise la fonction de détection d'un symbole de début de suppression incorporé dans le flux de données. Un registre RT (32) stocke des conditions de réception de signal lorsque la liaison est établie. Le signal d'horloge extrait, les conditions de réception de signal et le signal de début de suppression détecté sont utilisés pour rétablir la liaison.
(JA) リンクロスの状態から迅速に正常状態に復帰すること、ノイズ等の影響による画面のちらつきを防止することにある。CPU28が、初期リンク確立後に、リンクロスが発生したことを表すホットプラグ検知信号HPDのソース装置10への出力が無効状態になるように制御する。DPRX22における機能が、ソース装置10から継続して伝送されるデータストリームの受信中にリンクロスの発生を検出する。DPRX22における機能が、リンクロスの発生が検出された場合に、データストリームに埋め込まれたクロック信号を抽出する。DPRX22における機能が、リンクロスの発生が検出された場合に、データストリームに埋め込まれたブランキング開始シンボルを検出する。RTレジスタ32が、リンク確立時の信号受信条件を記憶する。抽出されたクロック信号、信号受信条件、及び検出されたブランキング開始信号により再リンクを確立する。
